SteamLevel® Heat Pump

Steam without combustion – for industrial pioneers

The SteamLevel® heat pump generates steam for industrial use from waste heat without using combustion. The steam heat pump is offered as part of a factory-built AmbiSteam® module for a quick turnkey installation.

Steam Heat Pump Brings Energy Efficiency for Industrial Processes

Designed for industrial use, the SteamLevel® heat pump doesn’t only reduce energy consumption, it also saves on energy costs and lowers CO₂ emissions.

The AmbiSteam® solution, which features the SteamLevel® heat pump, utilizes waste heat and refines it into steam that exceeds 5 bars, efficiently and emission-free, without the need for fossil fuels.

Waste Heat to Steam with a Steam Heat Pump

SteamLevel® is one of the first industrial steam heat pumps on the market, producing fossil-free steam from waste heat. It is suitable for various applications, such as hygienic processes, steaming, and sterilization.

As part of the modular AmbiSteam plant, The SteamLevel® heat pump offers plug-and-play compatibility with existing systems. The factory-ready AmbiSteam solution supports industrial sustainability goals by quickly and efficiently minimizing the costs and emissions of steam production.

SteamLevel® Heat Pump as Part of AmbiSteam® Plant

SteamLevel® represents the cutting edge of steam heat pump technology.

Calefa utilizes it in industrial sites where waste heat can be efficiently converted into processable steam.

The steam heat pump is always designed as part of a comprehensive energy production system and delivered as a turnkey solution, as part of Calefa’s AmbiSteam® heat pump facility.

“Steam production is one of several processes that has a substantial impact on industrial energy prices and carbon dioxide emissions. We are already accustomed to heat that is devoid of emissions. Now it’s steam’s turn.”

The SteamLevel® Heat Pump Enables Emission‑Free Industrial Steam Production

A steam heat pump that produces steam from waste heat efficiently replaces fossil fuels in industrial steam generation.

Traditionally, industrial operators have relied on electric or combustion‑based steam boilers and steam generators. With Calefa’s SteamLevel heat pump, 40–90°C waste‑heat sources can be utilized to produce steam exceeding 110°C.

Calefa continuously develops environmentally friendly and energy‑efficient heat pump solutions for the needs of industry and the energy sector. The use of natural refrigerants is a natural part of this development, as they support both high performance and responsible energy production.

The steam produced by the steam heat pump can be used effectively in a wide range of industrial processes — from battery manufacturing to the food industry

SteamLevel® – the Core of the AmbiSteam® Solution

The SteamLevel heat pump is among the first in Europe to enable fully emission‑free steam production based on waste heat. Thanks to these SteamLevel units, Calefa’s patented AmbiSteam solutions can provide industrial customers with steam exceeding 5 bars, entirely without combustion‑based energy sources.

Calefa uses SteamLevel heat pumps—manufactured at its own facility in Ikaalinen—in waste‑heat‑powered steam systems delivered as turnkey solutions for industrial customers.
