Frequently asked questions
Short, factual answers about the Commercial Duo Series.
What applications suit the Commercial Duo Series?
The Commercial Duo Series is a commercial air-to-water heat pump running on natural R290 refrigerant. With outlet temperatures up to 78 °C it covers industrial process heat, commercial hot water and high-temperature heating circuits, and it keeps operating down to -25 °C outdoors.
Why R290 for a commercial unit?
R290 (propane) has a global warming potential of about 3 and is unaffected by the EU F-Gas phase-down that is squeezing HFC refrigerants out of commercial equipment. It also reaches the high outlet temperatures — up to 78 °C here — that many commercial processes demand.
What warranty does the Commercial Duo Series carry?
Solimpeks backs the Commercial Duo Series with a 2-year product warranty, stated on this product page. Commercial installations should be commissioned by a qualified installer.
