Secop’s robust propane (R290) heat pump compressors are engineered to drive domestic hot water heat pumps. By utilising ambient air energy, these systems easily cover the annual hot water needs of two to three people, making them ideal for apartment complexes. With a typical tank capacity of up to 200 litres, they can produce roughly 600 litres of hot water within 24 hours. These compact, and powerful HC (hydrocarbon) refrigerant compressors offer up to 30% increased efficiency compared to HFC (hydrofluorocarbon) refrigerant solutions.
From 1 January 2027, heat pump manufacturers must complete the transition away from HFC refrigerants. The deadline is fixed. Secop's reciprocating propane heat pump compressors offer structural advantages over rotary solutions in for this kind of heat pump applications: low noise, compact size, stable performance throughout the entire product lifetime, and a robust design built for demanding operating conditions like high back pressure (HBP), and hot gas defrosting.
Furthermore, Secop heat pump compressors operate reliably at high evaporation temperatures and withstand extreme liquid refrigerant returns. To guarantee safety, the compressors feature a patented Secop hermetic terminal plug. This innovation ensures the secure use of R290 by preventing the root causes of electrical arcing commonly associated with flammable refrigerants.
The NLU8.8DN is designed to replace SC10GH/GHH or SC12GH compressors, while the NLE10DNDX can also serve as a replacement for SC15GH/GHH compressors. The NLU8.8DN provides a heating capacity of up to 2 kW, whereas the NLE10DNDX can deliver more than 2 kW (heating capacity = cooling capacity + power consumption).
