What is thermal underwear? How does it work and what is it used for?
Thermal underwear, associated with practicing sports in demanding weather conditions, is also a common choice for people who work outdoors at any time of year. It works great for construction workers, providing them with much higher thermal comfort while performing tasks. On the market we can find a wide selection of this type of clothing - including thermoactive. However, it's worth knowing what thermoactive underwear differs from thermal underwear and which one to choose. Thermal underwear: what is it and what does it do? Thermal underwear is clothing designed to provide high thermal insulation for the person wearing it. It ensures the maintenance of the body's thermal comfort while protecting it from cooling in low temperatures, which is why it works perfectly, for example, for outdoor workers in winter. Thermal clothing is usually made from natural fibres that provide proper warming properties - e.g. wool or cotton - supplemented by synthetic ones that prevent the loss of that heat - for example by protecting the body from wind. This type of clothing is therefore an ideal choice for people who spend long periods outdoors in low temperatures, providing them with thermal comfort and preventing the body from cooling down. How does thermal clothing work? You may be wondering: how does thermal underwear work? It is a type of clothing that functions similarly to a wool sweater. At the same time, however, it is much thinner and more comfortable to wear. Its role is to retain the heat generated by the warmed body and thus protect the user from cooling. Its construction allows this - the use of natural fibres such as cotton or wool, which retain heat, and synthetic fibres that insulate against the loss of heat obtained in this way - e.g. under the influence of wind. Thermal underwear is therefore the ideal choice for people working outdoors in winter or anyone else exposed to prolonged stays in freezing conditions with limited physical activity. For construction workers, buying a set of thermal underwear is a good choice - e.g. ZEVEN dark grey thermal shirt and ZEVEN thermal long johns. Thermal clothing and thermoactive clothing are not the same: learn the differences Thermal underwear and thermoactive underwear - you have certainly heard these terms used interchangeably. But is that correct? Not entirely. Every thermoactive garment is at the same time thermal, but it doesn't necessarily work the other way around. What is the difference between thermoactive underwear and thermal underwear? The role of the former is primarily the transport of moisture and its proper wicking to the outside, which helps maintain an optimal body temperature. Thermo garments are therefore ideal for people who perform physical activity outdoors in low temperatures - they will wick away sweat properly and help maintain optimal thermal comfort. Interestingly, thermoactive underwear is not only used in winter. The ventilation properties of this type of clothing mean it also works very well in summer - wicking sweat away and ensuring proper thermoregulation for the user. How does thermal clothing work? As we mentioned above - its main role is to maintain the proper temperature of the human body and to warm it. A set of thermal clothing, for example SIEG graphite thermal long johns and OSTE graphite thermal shirt will therefore be a good choice for people spending time outdoors in low temperatures and performing moderate physical activity. How to wear thermal underwear? Thermal clothing should be worn as one of the first layers of clothing - manufacturers usually recommend putting it on directly against the body to make full use of its properties. This is especially recommended in the case of thermoactive underwear, which will properly wick moisture only when worn as the first layer of clothing. Purchasing appropriate thermal or thermoactive clothing can significantly affect the comfort of tasks performed outdoors - regardless of the prevailing weather conditions. So if you are looking for clothes that will protect you from cooling while working outdoors in winter, opt for thermal clothing - you can choose proven models - OSTE blue thermal shirt and SIEG blue thermal long johns. If, however, you are looking for year-round clothing that will provide comfort and wick away excess moisture during intense physical activity - opt for thermoactive underwear.

What is DWR coating?
An important concept, most often encountered in descriptions of outdoor clothing, is the term DWR. It is an essential element of protection against rain. Durable Water Repellency (DWR) is a treatment of clothing that protects against rapid soaking by imparting hydrophobic properties. The coating that is added to fabrics by impregnation provides a thin water-repellent layer over which water can run off. The most commonly factory-applied agent for this purpose is a fluoropolymer.The DWR coating is therefore a great addition that enhances a material's water resistance. Fabric without DWR treatment looks heavy and soaked in the rain, even when the material has not actually become saturated. The DWR coating technique is now essential to ensure appropriate comfort of use. However, it should be remembered that through improper use or lack of care the DWR layer can be damaged. It is negatively affected by: oil cigarette smoke other types of contaminants washing is also detrimental. Therefore an important aspect is cleaning and refreshing the DWR coating, which allows us to enjoy the practical properties of the clothing for a long time. However, appropriate detergents should be used for this purpose. For a complete renewal of the DWR layer, a dedicated spray will be helpful, thanks to which our coating will be like new and clothing equipped with DWR will serve us for a very long time.Author: Grzegorz Nowak

Torque wrench. What is it? How to use it? How to set it correctly?
The correct torque is crucial for the proper assembly and operation of bolted connections in various structures and mechanisms. In such cases you cannot rely on feel alone; you must use appropriate tools that limit the maximum tightening force. However how do you set the correct Nm value on a torque wrench? And how do you calibrate a torque wrench? You can read about this in the article below What is a torque wrench and how does it work? To properly set a torque wrench, it is worth understanding how it works. The secret lies in a small spring. When the wrench encounters resistance, this spring stretches until the set torque (the Nm value on the scale) is reached — then a release of the lock occurs, preventing further tightening of the bolt. These tools belong to ratchet wrenches, which means they transfer torque in only one direction (tightening bolts). Analog or digital torque wrenches? Learn the different types Among popular solutions, one can particularly mention: Pointer (analog) torque wrenches. A classic solution equipped with a simple pointer and a graduated scale. This way you can monitor the correct tightening torque of bolts during work. Some models additionally have a locking pawl that prevents tightening beyond the set torque. Mechanical torque wrenches. The tool has a ratchet mechanism, so using a mechanical torque wrench is often associated with a characteristic click that indicates the set torque has been reached. Electronic torque wrenches. They have an LCD screen showing the current torque. Electronic wrenches store presets, which significantly speeds up work, especially in auto workshops. Break-type torque wrenches, which have an additional hinge. When the set torque is reached, the wrench 'breaks', preventing further operation. After removing it, it returns to the standard position, allowing further work. Whether they are click wrenches, or professional torque wrenches with a scale, it is important to set the wrench correctly. How do you use it properly? How to use a torque wrench? A torque wrench is a delicate precision tool. Therefore knowing why and how to use it is very important. A torque wrench is useful for tightening bolts during the assembly of many mechanical components, especially in automotive work or bicycles. Different types of wrenches have different torque ranges, so they must be matched to the specific application. Proper storage of torque wrenches and regular calibration of the tools are also important. Correct wrench setting allows you to achieve the right tightening torque and will indicate the correct torque measurement. What does Nm on a torque wrench mean and how important is torque? The wrench's measurement range is very important. It is marked with a scale expressed in Nm. It represents tightening torque values and stands for newton-meters. In other words it is the product of force (measured in newtons) and the lever arm at which it acts (in meters). By definition, one unit of torque means a force of 1 N acting on a lever arm (wrench length) of 1 m. The torque range depends on the mechanism used, i.e., the type of wrench. Why should torque wrenches be used? The user manual for many components specifies the need to use a torque wrench. Why is this so important? Sometimes there is a risk of damaging the connection if a bolt is overtightened. In other cases the bolt's structure may be compromised. In such a case the connection may fail at any time (e.g., during machine operation). Tightening wheel bolts should also be done with the correct torque so that the wheel does not come loose while driving. Precise tightening of bolts guarantees the proper functioning of the component. How to set a torque wrench for wheels? The tightening force for car wheel bolts is in the range of 110-140 Nm. Such a torque value secures the wheel against coming loose. Tightening wheel bolts should be done according to the vehicle's manual, because in some cases the recommended setting may fall outside the range mentioned above. It is also worth remembering that bicycle torque wrenches operate with much smaller torque. Which torque wrench will fit an engine? A wrench is also necessary when assembling an engine block. For this purpose a professional tool is used, whose torque measurement range is adjusted to that specific task. When assembling a block torque is important, but the correct sequence of tightening the individual bolts is equally crucial. Setting the torque wrench differs at various stages of engine assembly. It is often also necessary to calibrate the torque wrench before starting work. The correct torque ensures the sealing of the entire assembly and trouble-free operation. Remember that the engine is not the only component in vehicles. Bolted connections occur, for example, in the running gear and in many other constructions, including those not related to cars. Can you loosen bolts with a torque wrench? Torque wrenches are intended for tightening bolts. As for loosening — do not do this, because it can lead to damage to the mechanism. Such damage to a torque wrench excludes further use of it. Indicated tightening torque values may become inaccurate. In most cases there is no possibility to calibrate a torque wrench. Torque wrench: match the force to the application! Proper use of an electronic wrench starts with choosing its power. Which wrench is needed for a given task depends on the job. That is why different types of torque wrenches are available. How to choose them correctly? Tightening car and motorcycle wheels requires quite a lot of force. Therefore in this case it is worth choosing a torque wrench with a range from 40 to 200 Nm. To assemble an engine block, wrenches with a range up to 25 or 30 Nm are used. Smaller components, like spark plugs, have more delicate threaded connections. The best choice is a torque wrench with a range up to 25 Nm. Meanwhile, a torque wrench for valve stems has a range of only up to 0.45 Nm. The wrench's measurement range should be larger than the recommended setting, by at least several percent. Precise tightening is not possible near the ends of the scale, where the mechanism may show some deviations. Professional torque wrenches are designed for specific tasks so that recommended settings fall near the middle of the scale, providing the best accuracy of settings. Which torque wrench will work well in a home garage? Digital torque wrenches work best in a home garage, providing the correct tightening torque. The torque setting is made using buttons and options visible on the screen, which makes the torque wrench easier to use for people who need them only occasionally. Memory presets also make it easier to reconfigure the device for repetitive tasks. For professional operators different types of tightening wrenches are recommended depending on the task, such as a torque wrench for engines. However, in a home garage a universal model with a wide adjustment range is often sufficient. How to calibrate a torque wrench? What is tool calibration and how does it work? It is a check to ensure that the tightening force corresponds to the reading. Using a torque wrench relies on the correct tightening torque - therefore the measurement error cannot be too large. How to calibrate a torque wrench? The simplest way to calibrate is to send the wrench to a service. An alternative is to purchase a calibration device. This is a good solution for workshops that frequently use torque wrenches. Calibration should be performed at least once a year or after 5,000 uses. Author: Paweł Sokołowski

Power station: what is it and what is it used for?
Most devices around us require electricity to function properly. However, while traveling or on vacation access to the power grid is often severely limited, and sometimes even impossible. In such situations, reliable power stations that provide large amounts of electricity anywhere come to the rescue. They also work well as backup protection in case of a power outage. What is a power station? Modern technologies bring us closer together, but at the same time mean that without electricity we become completely cut off from the world. How to cope in such a situation? One solution is a power station: high-capacity batteries with universal USB, AC and DC outputs. Just plug in a computer or phone to regain access to the virtual world. Moreover, mobile power stations are also perfect for trips. Especially for various kinds of campsites where access to the power grid is limited. A small gel travel battery – a power station will make your stay more enjoyable. How does a power station work? Why is a power station so reliable? Because its operation is very simple. The most important components are lithium-ion batteries that store electrical energy. The device also has power inverters to provide the appropriate current parameters for connected devices (AC/DC). A power station does, however, require charging. This is most often done by plugging the device into a socket. But what if there will be no access to the power grid for an extended period? Then a power station with photovoltaic panels will be indispensable. With a bit of sun (which should never be lacking on vacation), the batteries will fill up with green energy. Power station and its applications Where are high-capacity batteries most often useful? Home power stations are very popular. They are an ideal backup in case of a power outage. You can connect an internet router to the station and recharge a laptop – useful for people working remotely. In winter it can also serve as emergency power for a furnace or other important home systems. On the other hand, portable power stations can be taken on vacation. While relaxing in nature, away from the hustle and bustle of the city, stations will allow you to top up the batteries of basic devices we use daily: phones, smartwatches, or navigation devices. You can connect several devices to a single power station. This way it can act as a large power bank during an organized trip. When away from home, a power station combined with a photovoltaic panel becomes a small solar power plant. Now you can enjoy access to green energy anywhere. It is a universal device with a reserve amount of electrical energy. The user decides when the stored power will be needed. Power station or generator — key differences How does an emergency power station differ from a generator? It may seem that both devices serve the same function, but their operation is completely different. A generator needs fuel, which is then converted into electricity by an internal combustion engine and an alternator. This means high noise levels and exhaust emissions. For this reason, in enclosed spaces a power station is preferable to a generator. Although its price is somewhat higher, it does not require the additional purchase of diesel oil or extra servicing. Additionally, a power station with a photovoltaic panel can generate electricity on the go — without noise or fumes. Emergency power station — usefulness and features Modern power stations provide energy security while traveling or on vacations spent in places without access to electricity. The available power of such devices varies by model. The smallest 350 W models allow 7 charges of a tablet or camera. They can also power a car fridge for over 4 hours. A 1000 W travel power station can power the same fridge for a 16-hour stop. These devices also have many additional features and conveniences. They can be charged in three different ways. The greatest security is provided by a power station with photovoltaic panels. In sunny weather it charges continuously, providing even larger power reserves. Stations allow connecting up to 8 devices to 5 types of outputs with voltages from 5 to 230 V. Wireless charging is also possible. In addition, all models, including the 600 W travel power station, are equipped with LED lighting. Energy-efficient and reliable lights are a perfect addition to evening conversations in a group. Which power station is best for home? A mobile power station for trips, especially with the ability to connect photovoltaic modules, is an excellent investment for travelers. Which power station will be best for home use? In that case, the device's weight is less important, while its capacity matters — you never know how long a network failure will take to fix. That is why a 1000 W or even 2000 W power station is the best choice. You can find such models in our store. Check our offer and never worry about sudden power cuts again!Author: Paweł Sokołowski
