EvoFlat FSS

EvoFlat^TM FSS is a compact and simple to operate flat station. Especially suitable for two-pipe systems in residential buildings, which are supplied from a secondary connected district heating system, a block heating system, a centrally located boiler system (oil, gas or biomass, as well as for CHP systems. The EvoFlat FSS^TM is available as built-in variant with a recess box or as mount-on-wall variant with cover.

Primary side (DH)
The flat station is prefabricated with interconnecting components such as a differential pressure controller (integrated in main temperature controller TPC-M), strainer, sensor pockets and fitting piece for insertion of a heat meter.

Heating (HE)
The self-acting temperature controller TPC - M with integrated differential pressure controller sets the optimum operating conditions for heating and DHW. In order to enable a time dependent temperature control program, a zone valve with actuator is included and can be connected to a room thermostat as an option.

Domestic hot water (DHW)
The domestic hot water is prepared in the heat exchanger based on the flow principle and the temperature is regulated by the self-acting controller with integrated differential pressure controller - the TPC-M. Supreme ease of operation is obtained via the combined hydraulic and thermostatic regulation of the TPC-M controller. The flow-controlled part allows primary and secondary side flow through the heat exchanger, only when hot water is tapped and blocks the flow immediately after completion of the tapping process. The thermostatic part controls the domestic hot water temperature. The TPC - M controller with integrated differential pressure controller also compensates for flunctuating flow temperatures and differential pressures and thereby ensures a constant domestic hot water temperature at all times.

For registration of the cold water consumption the EvoFlatTM FSS flat station is equipped with a fitting piece for mounting of a cold water meter in the DCW inlet.

Construction
All pipes are made of stainless steel. The connections are made by a newly designed click connection. Compared to conventional stations with screw connections, this new connection technology does not re­quire retightening during assembly.

Insulation
The EvoFlatTM FSS flat station is built up on an EPP insulated back plate as well as a front insulation cabinet, enabling the customer to have a fully insulated substation, thus ensuring reduced heat losses and excellent operating economy.
