Industry Applications

Karnot natural refrigerant heat pumps serve hotels, hospitals, commercial laundries, food processing plants, breweries, bottling facilities, pharmaceutical labs, swimming pools, data centres, cold storage warehouses, HVAC buildings, agriculture, plastic recycling, and advanced manufacturing. Systems deliver hot water from 55–90 °C, cooling to −40 °C, and ultra-cold storage to −130 °C using CO₂ and R290 refrigerants.

From hotels to hospitals, laundries to breweries — Karnot natural refrigerant systems deliver hot water, cooling, and process heat across every sector.

01

Hotels & Resorts

Hot water for guest rooms, kitchens, and on-site laundry. A typical 100-room hotel demands around 15,000 litres per day. Karnot systems handle peak loads while slashing energy bills by up to 70%.
