Cooling system
A cooling system must be provided on compressors in order to:
- Cool the gas after compression downstream of each compression stage.
- Cool the compression cylinders, which heat up due to contact with the compressed gas and to the friction of the moving parts.
- Cool the lubrication oil, which in turn cools all the moving mechanical parts of the compressor.
SAFE provides a water-cooled system. An air-cooled system can also be provided on request.
⠀
Water-cooled system features:
- It can be positioned outside the premises (on the forecourt or above the roof of the compressor room). It cools a water-glycol solution, which is sent to the compressor by an electric pump positioned on the same cooling system.
- It can be an ATEX version, i.e. suitable for installation in areas where presence of gas is possible (i.e. near the compressor/storage room openings when the space available does not allow the minimum distance to be respected).
- It can be configured to achieve minimal noise levels if required.
- The water-glycol solution cooled by the system on the compressor skid feeds the gas-water, oil-water heat exchangers and the cooling jackets of the compression cylinders.
The water cooling system can be supplied with the following components:
- Battery of fans
- Water pump
- Water tank
- Pressure indicator
