FMWi

Tomorrow's solution is here today. FWMi, the most intelligent fresh water module on the market with high effiency pumps works with any type of water quality. No hot water storage required, which prevents development of legionella.

 

NEW PLATE HEAT EXCHANGER
Copper brazed for “normal” water qualities. Stainless steel brazed for harsh water qualities. The intelligent flow control insures resistance to corrosion and scaling.

 

HIGH EFFICIENCY PUMPS
The Grundfos Alpha Pump is the brain of the module. It collects input data from all sensors and controls all basic functions in the FWMi.

 

INTELLIGENT CIRCULATION PUMP
The optional circulation pump can learn when the household needs hot fresh water and supplies the correct quantity right on time. Thereby saving energy.

FWMi Cascade

With the new FWMi-Cascade up to 4 x FWM30i can be installed in parallel. So SONNENKRAFT has the optimum solution for the hot water production for all middle to large scaled projects up to ~120 l/min delivery rate.

 

EFFICIENT SIZING

The sizing of a FWMi cascade can be done very precisely to reach the real hot water demand very exactly and to achieve the highest level of economic efficiency.

 

EASY EXTENSION

An unexpected increase in hot water demand in the future can be met easily by extending the cascade.

 

SECURITY OF SUPPLY

The FWMi cascade ensures security of hot water supply during maintenance. A precise sizing up to the actual hot water demand avoids lime and corrosion.
