heat exchanger by forming a mixing temperature. The heat exchanger and condenser are constructed in a
natural circulation design so that operation is possible with a random combination of high and low temperature
return water volumes. The condensate which arises during operation is collected in a stainless steel trough under
the condenser and then siphoned off.
The VARINO GRANDE is available in two design versions. The standard design is a monoblock version. In the
case of narrow delivery conditions, the boiler block of the unit can also be supplied in several parts as an option.
In this version (VG-TB), it can be still be brought through doors that are only 800 mm wide.
Since the components of the VARINO GRANDE condensing unit have already been co-ordinated and optimised,
connection to a hydraulic network and commissioning are very simple.
