Application reports


The 2.000 m² should be kept at max. 25°C in summer, in winter the hall should be warmed up to 18°C with the same system. The conversion of the heating and cooling system had to be carried out during running operations.

The year round requirements for the new heating and cooling system require 18 ° C to 25 ° C and a relative humidity of less than 60%. In addition to the heating system already installed, a further system should ensure cooling in the summer as well as maintaining the humidity.
