How does a screw compressor work?

A screw compressor can run loaded ('pumping air') or unloaded ('idle'). The inlet/loading valve opens and closes according to air demand. The inlet valve is controlled by a solenoid valve that supplies control air to the inlet/loading valve. Check solenoid valve coil and solenoid valve operation.

Why is it important to piping air compressors to the header?

Properly piping compressors to the header is extremely important especially because improperly piped air compressors can cause leaks, pressure drops or machine failure. If the piping is too small than the velocity of the air will increase.

Should you duct a compressor room?

If the design of the compressor room makes it too difficult for cooling air to flow across the compressor then ducting is the best alternative. You have the option of ducting both the inlet and outlet air, or just one, depending on your current setup.

What causes a compressor to shut down?

Cool air needs to flow across all of the equipment in the room. This is why it is critical to have intake and exhaust ducts on opposite walls. One of the most common reasons for compressor shutdowns is due to high temperatures, typically occurring when there is insufficient ventilation.

How much heat does a rotary screw compressor produce?

For example, a rotary screw compressor will produce approximately 3000 BTU/hr of heat energy per horsepower. Ideally, the installation will use this heat energy as an extra heat source in cold weather months or to heat water for an application. If the heat is unable to be reused then proper ventilation is critical.

How should a compressor room be ventilated?

If the heat is unable to be reused then proper ventilation is critical. Ventilation air should be drawn from the exterior of the compressor room at the lowest and coolest possible point on one of the room’s walls. On the opposite wall, temperature-controlled ventilation fans should be installed at the highest point of this wall.
