Electronic fresh water station

Electronic fresh water station

Modvfresh is a thermostatic module for the production of domestic hot water.

Suitable for installations with domestic use up to small communities, is used for applications of inertial storage tanks connected to sources such as heat pumps, biomass boilers and solar systems.

DHW production occurs instantaneously, using the brazed plate heat exchanger thus avoiding bacterial. 

The variation in flow demand is read instantly from a digital sensor that provides information to the electronics of flow and temperature, consequently modulating the speed of the circulator.  

Modvfresh is a Pre-assembled station for the management of hot water.


Flow station electronic hot water

Intelligent electronic management

The electronic regulation of Modvfresh guarantees the production of instant hot water, avoiding bacterial proliferation phenomena, such as legionella, due to the stagnation of water in the accumulation. 
In Modvfresh electronic, the VFS sensor instantly detects the change of flow and consequently the control unit adjusts the speed of the circulating pump, to obtain the best yield of the plant.
The digital sensor VFS also allows a precise accounting of the energy produced.

Hot water station alternative sources


Matching alternative energies

Modvfresh is recommended to produce domestic hot water accumulators in combination with inertial systems connected solar thermal, wood boilers, pellet, biomass, etc..

The version from 20 l / min is suitable for installations of domestic use; version from 40 l / min is to be used for small communities. 

The plate heat exchanger made of stainless steel with large surface area provides an important heat exchange, which allows the water return to the puffer with a temperature up to 15 ° C.

This promotes a perfect rendering of the solar heating and also a heat pump.
