Have you got money to give away?
If your answer to this question is "No", you should make use of the potential energy savings achieved by distributing the heat from your compressor!
The energy consumed for generating compressed air is fully converted into heat.
The heat diagram shows the quantity of heat that arises on an oil-injected screw compressor (the values may vary slightly depending on the design).
Waste heat from oil-injected screw compressors can be utilised in the following ways:
Hot air for heating purposes
The heated cooling air is used to support the room heating via a anal system. Temperature-controlled flaps are used to achieve a controlled, adjustable room temperature.
In winter the heat from the exaust air is used completely or partially for heating purposes, in summer it is blown outdoors via an exhaust air channel.
Heating water
For this process, the heat taken from the oil that is discharged via the oil cooler in the normal operating mode is transferred to the water that has to be heated via a heat exchanger (plate or shell-and-tube heat exchanger).
Some 72% of the electrical energy thus absorbed can be utilised.

Heat for process waterPotential energy savings through heat distribution
A compressed air station requiring 160 kW consumes approximately 1,280,000 kWh p.a. for 8,000 operating hours. There are good possibilities for recovering this output in the form of hot exhaust air or hot water.
The quantities of energy that can be saved depending on the installed rated power output of the compressors can be seen from the table below:

You have two alternatives:
- To purchase a new compressor with integrated heat disribution, i.e. save money from the very beginning
- It is also quite feasible to retrofit existing compressors / compressor stations.
