Calefa product offering
Product offeringCore offering
Calefa designs, manufactures, and delivers turnkey modular heat pump and steam plants (AmbiHeat and AmbiSteam product lines, 350 kW–30 MW) that convert industrial waste heat, wastewater heat, flue gas heat, and ambient energy sources into emission-free heating, cooling, and industrial steam. Systems are built on Calefa's proprietary HotLevel® and SteamLevel® heat pump technologies and are delivered as factory-prefabricated, project-engineered installations complemented by the recurring CalefaCare lifecycle service.
Product overview
Calefa offers a modular energy solutions platform centered on two core product lines: AmbiHeat® and AmbiSteam. AmbiHeat® is a modular heat pump plant system (350 kW–30 MW) that can be configured with Calefa's proprietary HotLevel® heat pump technology, electric boilers, and thermal energy storage to produce carbon-free heating and cooling from ambient energy and industrial waste heat. AmbiSteam uses the SteamLevel® steam heat pump technology to produce over 5-bar steam from waste heat. The portfolio also includes Retrofit waste heat recovery systems retrofitted into existing factory infrastructure, Calmari heat exchangers, and CalefaCare — a lifecycle maintenance and service program covering remote monitoring, scheduled maintenance, and optimization. All products are manufactured in Finland (Hollola design, Ikaalinen production) and delivered as turnkey solutions.
