• Mr.Kerry Robinson from Australia
    today I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption.

    We've been used Shanghai Rotorcomp compressors over 18 sets from 10hp to 160HP installed with Oxygen generator since 2008. Most of compressors still in good working conditions without much maintenance.

Description of 200HP 28m3/min compressed air dryer for 200Kw industrial air compressor:

1. As reliable compressor dryer manufacturer, Air heat exchanger using corrugated copper tube inner and outer walls, increasing the cooling capacity utilization, countercurrent structure, return temperature is good, no condensation.

2. Evaporator processing thin-walled copper tube with a hydrophilic aluminum fin, spoilers structure heat transfer efficiency in our refrigerated Air Dryer.

3. The Sewerage system of refrigerated compressed air dryer optimization. Cold and dry structure using three or more drainage, timely and effective emit large amounts of condensate and oil, and thus ensure that the system clean and dry air also reduces the system load.


What is the impact of the ambient temperature on the operation of the dryer?

High ambient temperature is very unfavorable for the cooling of the refrigeration system.

When the ambient temperature is higher than the normal refrigerant condensation temperature, the refrigerant condensation pressure is forced to increase, which will reduce the compressor cooling capacity and eventually lead to the “pressure dew point” of the compressed air. Raise.

In general, a lower ambient temperature is beneficial to the operation of the dryer.

However, at too low ambient temperatures (eg, below zero degrees Celsius), the compressed air dew point does not change significantly, although the temperature of the compressed air entering the dryer is not low. However, when the condensate is drained outward through the automatic drainer, it is likely to freeze at the drain, which must be prevented.

In addition, during shutdown, the condensed water originally accumulated in the evaporator of the dryer or the condensed water accumulated in the water storage cup of the automatic drainer may freeze, and the cooling water stored in the condenser may also freeze, all All of this will cause damage to the components related to the dryer.
