Screws are commonly referred to as wood screws; they have a pointed tip with a larger pitch, typically used for fastening wood or plastic parts. Mechanical screws, on the other hand, have a smaller and more uniform pitch, designed for securing metal or machine parts. Our product range includes high-quality screws with long service life. Our company has obtained ISO9001 certification, ensuring product quality. The application areas of our screws include: 1. Stainless steel plates, metal plates, galvanized steel plates, and engineering installations. 2. Metal curtain walls, light compartments, and other indoor and outdoor installations. 3. General angle steel, channel steel, iron plates, and other metal materials combined installation. 4. Car trunks, container boxes, shipbuilding, refrigeration equipment, and other assembly works. 5. Automobile engines, heavy machinery, garden machinery, and petrochemicals. 6. Aerospace, energy, machinery, chemicals, military, metallurgy, molds, and hydraulics. 7. Motorcycles, sports equipment, cars, and many other industries. 8. Electronics, electrical appliances, motors, lighting, communications, home appliances, and furniture.

Externally Heated Desiccant Compressed Air Dryers
For decades, compressed air users have relied on YUKA HL-WR series heated desiccant air dryer to deliver technology that reduces the cost of operation and improves the reliability of air driven processes.
The HL-WR Series is engineered to deliver ISO 8573.1. Air Quality and reduce purge air consumption.
The micro heated regeneration adsorption dryer is a kind of humidification purification device that uses micro heat regeneration method to adsorb and dry compressed air according to the principle of pressure swing adsorption.
Feature & benefit
1. Micro-thermal regeneration adsorption dryer (hereinafter referred to as micro-thermal suction dryer), which has the advantages of both heating regeneration and non-thermal regeneration. The regeneration gas is micro-heated to reduce the regeneration air consumption and the regeneration is more thorough, Extend the tower switching cycle.
Under normal operating conditions, the dew point (under pressure) of the air can be reduced to below -40℃, and the lowest can reach -70℃. It can provide oil-free and water-free high-quality compressed air for a few applications that have high requirements for air quality.
It is especially suitable for use in cold areas in the north and other places where the ambient temperature is below 0°C.
2. The micro heat absorption dryer adopts a double tower structure, one tower absorbs moisture in the air under a certain pressure, and the other tower uses a small portion of dry air slightly higher than atmospheric pressure to regenerate the desiccant in the adsorption tower after a certain period of time , The two towers are switched to ensure continuous supply of dry compressed air.
3. On the basis of having all the advantages of the non-heat regenerative adsorption dryer, it adopts high-quality stainless steel finned U-shaped heating tube, which has uniform heating and high heat transfer coefficient, which can ensure long-term trouble-free operation.
4. Unique computer control system, visually display the running status of the dryer, and has multiple alarms, protection functions and DCS remote control interface to ensure trouble-free use.
5. The actuator adopts pneumatic angle seat valve and pneumatic butterfly valve. The pneumatic control system adopts deep dry air source and then filtered to ensure reliable action and avoid valve leakage.
6. The height and diameter of the adsorption tower are accurately calculated and experimental results, and the important parameters such as flow velocity and heat and mass transfer are indeed mastered, so as to avoid excessive wear of the adsorbent and tunnel effect.
7. Professional program control design, small air pulse and air pressure fluctuation, effectively reduce the outlet air dust and the regeneration air noise.
8. Convenient and practical cycle time mode and energy-saving economic mode. Regenerative air volume and time program can be adjusted to adapt to various actual use conditions and outlet dew point requirements. The support base has a stable and beautiful appearance, and is easy to install, use and maintain.
