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.

Rotary vane pump can be sealed off the sealed container of dry gas, if accompanied by gas-town device, you can also pump a certain amount of condensable gas. However, it is not suitable for the extraction of gases that are highly oxygenated, corrosive to metals, react chemically to pump oils and contain particulate dust.
Rotary vane pumps are one of the most basic vacuum acquisition devices in vacuum technology. Rotary vane pump for small and medium-sized pump. Rotary vane pump has a single-stage and two-stage. The so-called two-stage, is the structure of two single-stage pump in series. Generally made more double-stage, in order to obtain a higher degree of vacuum.
The relation between pumping speed and inlet pressure of rotary vane pump is as follows: Under the inlet pressure of 1333Pa, 1.33Pa and 1.33 × 10-1 (Pa), the pumping speed shall not be less than 95% of the nominal pumping speed of the pump respectively, 50% and 20%.
