Heat Recovery System
Model: PTG 140 - 55
- Hot water from KAESER rotary screw compressors -

Heat recovery reduces costs and protects the environment. By reusing warm air, up to 96% of the energy consumed by the compressor can be recovered. Using a PTG plate heat exchanger, up to 76% of the compressor’s energy consumption can be recovered as hot water.

Each liter of fuel saved reduces CO2 emissions by 2.727 kg, which is beneficial not only for the environment but also significantly lowers energy costs. At today’s energy prices, payback period for a heat recovery system varies between 6 months and 2 years (when using the recovered heat with a plate heat exchanger in the heating system).

Technical specification (operating characteristics for the compressor at full load, at maximum working pressure)
- Maximum available heat: 66 (238) kW (MJ/h)
- (after internal heat losses are deducted)
- Water circuit pressure drop: < 0.1 bar
- Water heating from 15°C up to 70°C
- Water flow at Δt = 55 K: 1.03 m³/h
- Potential savings*: €10,411/year
- CO2 emission reduction: 40,559 kg/year
- kWh/l; for 2,000 operating hours
