Q: What refrigerants are available for Kolant heat pumps?
A: Kolant offers multiple refrigerant options to meet different regional regulations and application requirements:
- R290 (Propane) – Natural low-GWP refrigerant, GWP≈3. Main option for EU market, ideal for residential all-in-one heating & cooling systems and pool heat pumps, compliant with F-Gas regulation and achieving A+++ energy class.
- R32 – Low-GWP refrigerant widely used in EVI ultra-low temperature units, pool heat pumps and ice bath chillers. It delivers excellent performance at low ambient temperatures and is a popular selection for European exports.
- R410A – Traditional refrigerant adopted on older models and some dual-source heat pumps. It is gradually phased out for new EU projects due to F-Gas restrictions.
- R410A + R134a (Cascade system) – Special solution for high-temperature industrial heat pumps. This two-stage cascade unit can work at -35°C ambient temperature with maximum water outlet up to 90°C. Separate circuits use R410A and R134a respectively.
Q: How to choose the refrigerant version? A: New projects for Europe normally select R290 or R32.
R410A is only available for legacy model replacements. High temperature industrial heating applications adopt the cascade system with R410A + R134a.
