DSP MINI

a Danfoss Platform for Flensburg Secondary Network

General description and
application

The DSP MINI is designed for use in district heating
networks, suitable for heating and for providing
DHW for single family houses. It provides an alter­native solution to an oil or gas boiler. The DSP MINI
is designed for heating, do mestic hot water and floor
heating. The wall- mounted construction saves space
which is needed for installation and service.

The DSP MINI is designed as a wall -mounted sta tion.
Each station is equipped with micro plate heat
exchangers for DHW and optional for heating man­ufactured by Danfoss, which significantly increase
substation performance and lifetime. All compo­nents are placed at the front of the station, which
makes it very easy to access them during mainte­nance or servicing. The mounting bracket signifi­cantly reduces the time required to mount the sub­station to the wall. The connections are predefined
and allow installers to prepare installation before
station is available on the site, which reduces the
time between deliver y and startup. Piping prepared
with automatic welding machines ensures th e high­est possible welding quality.

DSP MINI is equipped with high quality Danfoss
components, which are tested, approved and opti­mized for safe and reliable operation:

• ECL Comfort 310 controller

• Motorized control valves

• AVTB self-acting temperature controller

• AVPB-F Differential pressure controller with flow
limitation

• Brazed MicroPlate™ Heat exchanger, XB06

• Primary side polyurethane insulation according
50% ENEV 2013

• Metal box with door
