Heat Recovery Systems

Certified plant technology for various industrial applications


Heat recovery systems become increasingly important especially when energy costs are rising.
Depending on requirements, direct or indirect heat recovery can be achieved by effective heat displacement or exhaust gas heat usage. 

Direct heat recovery
In direct heat recovery systems using exhaust gas heat, excess heat from an exhaust
gas or residual heat from fluid or vaporous media is transferred to a medium which
can use this energy directly through heat displacement..

Indirect heat recovery
Indirect heat recovery means heat displacement.
It involves a transfer medium circulating between the waste heat unit and the heating unit.
This form of heat displacement allows a decentralized arrangement of the respective transfer systems and is particularly suitable at low temperatures
or in exhaust gas heat usage where there is possible dehumidification. Peripheral devices are also needed for indirect systems,
e.g. pumps, valves, vessels, switch cabinets and support constructions.






All Agetherma heat exchangers – apart from pressureless gas-to-gas systems – are classified under
the Pressure Equipment Directive PED 2014/68/EU and calculated, fabricated and certified under the associated regulations.
Exhaust gas heat usage:

Crude gas pre-heating using exhaust gas
Waste heat utilization in order to produce steam
Direct cold/warm water exchange
Heat displacement:

Residual heat usage
Condensation heat usage
Heat transfer between two gases
