Why Choose Our Refrigerant Air Dryer?
(1) Stable Performance And Dew Point
We design a heat exchange system for the dryer with HTFS software. There is a margin of more than 20%. It adopts a counter-flow design. So the heat transfer efficiency is higher. The evaporator and air exchanger adopt the structure of copper tubes and aluminum fins. High heat exchange efficiency. Oltretutto, the air volume of the condensing fan is large. Increase the cooling effect of a low-pressure air dryer. So ensure long-term efficient and stable operation of the system.
(2) Famous Brand Refrigerant Compressor
This low-pressure refrigerator air dryer uses a Copeland compressor. It is a famous brand and has super performance. In primo luogo, it has a high cooling effect and stable quality. In secondo luogo, this compressor has an internal safety device. So make sure that the refrigerant dryer works well. Oltretutto, it has low noise and is power-saving and durable.
(3) High-quality Refrigerant Spare Parts
In primo luogo, we use the Danfoss brand expansion valve. It can control the supply of refrigerant entering the evaporator. So can prevent liquid refrigerant from flowing into the compressor. In secondo luogo, it uses an EMERSON brand filter dryer. It purifies the refrigerant. Protect the refrigeration system. In terzo luogo, the refrigerated dryer uses a Sporlan brand hot gas bypass valve. It can maintain the evaporating temperature above zero all the time. So avoid water freezing and ice blockage.
(4) 99.9% Air-water Separation Efficiency
The dryer uses a three-stage steam-water separator. It can separate 99.9% of liquid moisture from compressed air. Prevent secondary evaporation of water. So it can guarantee the low dew point quality of the product air.
*How to Choose Low Pressure Refrigerated Air Dryer For Air Compressor?
Infatti, for low-pressure dryers, there is a quick selection formula:
Dryer air flow=air compressor airflow * 8bar/(working pressure +1bar)
This formula applies to dryers, filters, coolers, eccetera. The pressure range is 3.5 bar to 6 sbarra. Volume is inversely proportional to pressure. So the lower the pressure, the higher the dryer flow.
Assume that the air compressor capacity is 13.5Nm3/min. Its exhaust pressure is 0.45MPa. La temperatura di scarico è di 40°C. Inoltre, it needs a pressure dew point of 2 a 10°C. Poi, the airflow of the refrigerant dryer = 13.5*8/5.5=19.6 Nm3/min. Perciò, choose a 150P air dryer.
The pressure drop will be too large if the dryer selection is too small. It will also cause problems such as substandard export dew point. Inoltre, if there are strict requirements for pressure drop, it requires a special design.
Domande frequenti
This low-pressure dryer has no remote control function. But we can customize it and add PLC.
Our compressed air dryer has reliable quality. And the lifespan is one year. It means that we’re responsible for dryer quality. If there is a problem, we provide free accessories.
The refrigerant of this dryer is R22. But we can also supply other eco-friendly types, such as R410A, R407C, and R134A.
