DSP MINI light
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, domestic 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 station. 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 delivery and startup. Piping prepared with automatic welding machines ensures the 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 110 controller
•Motorized control valve VS2 with AMV actuator
•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
