Nolsen is a pre-assembled compact heat center for heat pump systems with high technical specification.
The main unit of the heat center is a stainless steel combined tank – 80 liters buffer, 400 liters DHW -, which is specially developed for heat pump heating/cooling system.
Components of Nolsen heat center
– Stainless Steel combined tank (DHW SUS316, Buffer SUS304)
– 35 mm stainless steel pre-assembled pipe system
Primary side
– Microbubble separator
– Magnetic dirt separator
– Change-over valve with rotary actuator
– 5/4″“ ball valves
– Automata air vent
– Safety group
Direct circuit
– Pre-assembled pipe system
– Circulator
Mixed circuit
– Pre-assembled pipe system
– Circulator
– Mixing valve with 24V or 230V rotary actuator
The direct circuit installation kit is available as an optional element as a stainless pipe system of Nolsen heat center. Through this, we can transmit the heating or cooling water produced by the heat pump directly, without mixing back, to the low or high temperature heat emitters.
