Le pompe di calore Kolant EVI sono in grado di funzionare correttamente anche nelle rigide condizioni climatiche della Scandinavia. La loro tecnologia di base è ottimizzata specificatamente per gli ambienti a bassa temperatura, rendendole pienamente compatibili con il clima locale.
EVI (Enhanced Vapor Injection) technology significantly improves low-temperature heating performance through quasi-two-stage compression and vapor injection enthalpy increase design: in the region’s typical winters (-2°C to -6°C), the Coefficient of Performance (COP) reaches 3.0-3.5, 20-40% higher than traditional heat pumps; even in extreme low temperatures (-15°C to -35°C), it can still maintain over 70% of the rated heating capacity with a stable COP above 2.0, far exceeding the low-temperature attenuation bottleneck of traditional heat pumps. It can even cope with the extreme cold of -30°C around the Arctic Circle.
These units meet Scandinavia’s usage needs: they adopt low-GWP environmentally friendly refrigerants, complying with local strict emission regulations; the split-type design combined with an anti-freeze heat exchange system prevents pipeline freezing; the operating cost is 2-3 times lower than electric heating, and the lifespan reaches 15-20 years, matching the standards of local heating systems. Only in rare extreme low-temperature weather (such as prolonged severe cold below -35°C) is short-term auxiliary heating required, which does not affect daily stable operation. It is an efficient and environmentally friendly heating option in the region.
