Norwegian company Enerin AS has launched the HoegTemp®, a scalable industrial heat pump capable of delivering high-temperature heat up to 250°C, offering a sustainable solution for demanding industrial processes and accelerating the shift towards electrified, low-carbon industry operations.
Norwegian heating technology specialist Enerin AS has introduced an industrial heat pump, the HoegTemp®, that delivers high-temperature heat up to 250°C, tailored for demanding industrial applications. The system’s design and operational flexibility represent a significant advancement for sectors seeking efficient, sustainable solutions for process heat decarbonisation, a key challenge within industrial decarbonisation efforts.
The HoegTemp® heat pump operates on the Stirling cycle, utilising helium (R704) as the working fluid in a closed single-phase system where compression and expansion occur via double-acting pistons. This technology enables the pump to efficiently convert electricity into heat at high temperatures, supplying steam, hot water, or thermal oil depending on process needs. The heat pump can deliver scalable heat supply capacities from 0.2 MW up to 1 MW per unit, with the option to link up to five units in parallel to reach a total of 5 MW capacity. At roughly 30 square metres and 10,000 kilograms, a 1 MW system offers a compact footprint for industrial-scale applications.
Enerin’s system showcases a coefficient of performance (COP) ranging from 1.80 to 2.16, illustrating a favourable balance between electricity input and usable heat output at elevated temperatures. The heat pump is engineered to adapt dynamically to fluctuating operating conditions, such as rapid changes in heat source temperatures or variations in heat sink requirements, without compromising efficiency. Sound levels, measured at approximately 80 dB(A), are within acceptable industrial norms. The pump’s heat transfer circuit can integrate with thermal energy storage (TES), optimising energy utilisation further.
The technology’s industrial viability is reflected in notable installations: GE Healthcare in Lindesnes, Norway, employs a 400 kW HoegTemp® heat pump supplying steam for distillation and solvent recovery in contrast agent production, operating with an automatic mode to adjust to varying steam pressure demands between 1.8 and 2.5 barg. Pelagia AS, a seafood processor in Måløy, Norway, utilises a 400 kW unit integrated into a broader 1.6 MW system, harnessing seawater and recovered waste heat to generate high-temperature steam for fish-oil production, highlighting the technology’s versatility across different industrial verticals. Additionally, IVAR IKS Biogas has also trialled the system.
With over 15,000 operational hours logged in real industrial environments, the HoegTemp® has demonstrated robust performance at source temperatures from 15°C to 65°C and sink temperatures reaching 200°C, with a Carnot efficiency range between 45% and 60% that improves alongside temperature lifts. The maximum temperature lift capability stands at 260 K, with the full operating range extending from -10°C to 250°C. Enerin projects the heat pump’s lifespan at 20 years, pairing durability with high technology readiness (TRL 9), which denotes commercial maturity and readiness for broad deployment.
Financial backing and strategic partnerships underline Enerin’s market confidence. The company recently closed a Series A funding round of NOK 180 million (approximately $17.7 million), led by Climentum Capital, The Footprint Firm, Johnson Controls, and Move Energy, with involvement from PSV Hafnium and Momentum. Johnson Controls’ participation is particularly notable, affirming the system’s potential within the industrial heating landscape. Enerin is also progressing towards obtaining UL certification to access the U.S. market, with certification expected by mid-2026.
Further collaborations underscore the industrial applications of the HoegTemp®. Circular Energy Systems is integrating the technology into their CircleDRY electric drying platform in Denmark, aiming to achieve energy and CO2 reductions of 50-80% at temperatures up to 250°C, with demonstrations planned through 2026. This alliance highlights the heat pump’s role in advancing circular and low-carbon industrial processes.
The HoegTemp® exemplifies a shift towards electrifying high-temperature industrial heat, traditionally supplied by fossil fuels. As industries face mounting pressure to decarbonise processes that require temperatures exceeding 200°C, heat pumps such as Enerin’s offer a promising pathway. By leveraging the unique Stirling cycle and helium’s thermodynamic properties, the technology fills a gap unaddressed by conventional vapour-compression or gas-driven heat pumps.
Enerin’s innovation, validated through operational pilots and strategic investments, aligns well with industrial energy transition goals. Its capacity to deliver reliable, high-grade heat sustainably and with flexible operation has the potential to become a cornerstone technology in reducing industrial carbon footprints, supporting sectors from pharmaceuticals to seafood processing and biogas. The integration of advanced heat pumps like HoegTemp® marks a pivotal development in the evolving landscape of industrial decarbonisation solutions.
