What KAISAI does
KAISAI is a commercial HVACR (Heating, Ventilation, Air Conditioning, and Refrigeration) brand owned and exclusively imported by Klima-Therm Sp. z o.o., a privately-held Polish company headquartered in Warsaw. Founded in 2018, KAISAI provides air conditioners, multi-split systems, mini VRF systems, heat pumps, and a Home Energy Management System (KAISAI X HEMS) for residential and commercial buildings. The portfolio spans wall-mounted, cassette, ducted, floor, ceiling, and portable AC units; multi-split lines (M-Line, T-Line); Mini VRF and R410A condensing units; and an extensive heat pump range including R32 split and monoblock Arctic-series units (6-30 kW), high-capacity Arctic Power commercial heat pumps (65-140 kW) using EVI technology for operation down to -25C, and R290 propane monoblock heat pumps (KHOA, KHON, KHY) with A+++ energy ratings. Supporting accessories include DHW/buffer tanks (KTFD) and the KXL-01 Lite control system.
Technically, KAISAI's products are differentiated through inverter technology (claimed energy savings up to 80%), WiFi connectivity as standard, R32 and R290 refrigerants (zero ODP for R290), air purification features (BioHepa filters, UV-C sterilization, ionisation), and the KAISAI X HEMS that integrates photovoltaic, battery storage, and HVAC equipment using algorithms that consume weather forecasts and dynamic tariff data. Compliance is broad: MCS, Keymark, EPREL, Ecodesign (ErP), and EU Declarations of Conformity across model lines.
The go-to-market is exclusively indirect: KLIMA-THERM does not sell direct to end users or online. Products flow through Klima-Therm subsidiary hubs in Germany, Estonia, Finland, and Slovakia, and a network of over 50 authorized distributors and installers across 25 European countries, supported by 11 country-localized websites. Customers are segmented horizontally across homeowners, apartment residents, offices, hotels, and restaurants, with the heat-pump portfolio specifically serving the renewable-energy/eco-heating segment. Revenue is generated purely through hardware sales (AC units, heat pumps, accessories, HEMS components) at the distributor level; pricing is not publicly disclosed and is set channel-by-channel.
