Oil flooded rotary screw air compressor - low ambient temperature
Oil flooded rotary screw air compressor - low ambient temperature
(OP)
My company just purchased two air-cooled oil flooded screw air compressors. The actual site temperature range is -15 to 40 C,but the manual says the air compressors can only operate at the minimum ambient temperature above 0 C.
Is the 0 C degree limit applied for all oil-flooded air compressors?
Is there any solution for that problem? Since the air compressors are indoor installed with duct on outlet. I plan to have an electrical damper on the outlet duct, when the compressor room temperature is below zero C degree, the damper will close, and a bypass opening will conduct the exhaust hot air to the compressor room to warm it. Please see if it is practical.

I contacted with the Vendor, it seems that 0 C is their standard. They don't want the room temperature under zero degree. Using exhaust hot air to warm the room in the winter is their proposed solution. Since oil flooded screw compressors are widely used in the world, I am wondering if they are operating in this way in the winter, anyhow, only a small portion of the world are tropical.

There are a lot of possible techniques, but they all require knowledge of the local conditions and of the heat sources that a clever engineer can adapt to his needs.
