Multi II
The Multi II was developed to recover heat from used shower water from
multiple showers. For example in apartment buildings, hotels, hospitals,
sports clubs or the shower water from swimming pools.
The heat recovery takes place by means of the countercurrent principle. The
Multi II consists of four interconnected Showersave® heat exchangers with
central distribution units for wastewater and for domestic hot water. These
are constructed in such a way that the Showersave® heat exchangers have an
optimal flow for both the fresh water and the sanitary water. The
Showersave® heat exchangers have a double barrier according to NEN-EN
1717.

The MultVert II is available with Showersave® heat exchangers in three
different lengths.
3 different lengths. For larger flow volumes, multiple Multi II units can be
connected together. For occasional peak flows a bypass is available.
Other applications
In other applications where also a lot of hot wastewater enters the sewer, the
Multi II can often be used as well. However, there must be a simultaneous
removal of waste water and supply of fresh water. This may be the case for
example in rinse kitchens, laundrettes, rinse water refreshment or cooling of
waste water.
Because the heat exchangers are made of copper, the composition of the
wastewater must first be examined to ensure that it does not affect the copper. If
that is the case, there is the option of making the wastewater circuit in stainless
