SIGMA plate heat exchangers are used in the most varied applications
in plant and machinery construction. Their primary tasks are in the reliable
provision of cooling media, such as water, thermal oil and other coolants.
As well as that, our heat exchangers perform the most diverse tasks in the
area of heat recovery, in order to operate your machines and systems as efficiently
and environmentally compatible as possible.

Typical tasks for SIGMA plate heat exchanger in industrial plants are:
- Cooling of engine cooling water
- Oil cooling for screw compressors
- Oil cooling for steam turbines
- Oil cooling for compressor cooling
- Central cooler unit e.g. with river or sea water
- Cooling of waste water
- Heat recovery of waste water
Application example: Underwater granulation
In the manufacture of plastic compounds, so-called underwater
granulation processes are used more frequently today. In this case, the
hot sealing compound is discharged from the extruder directly into water and
granulated. The water absorbs the heat of the compound, where it solidifies.
In order to ensure a constant temperature of this water, the water flows through
a SIGMA heat exchanger and maintains the required temperature. The SIGMA
heat exchanger is connected with the central cooling-water system of the system
in this case. |
