Ring Capital joins Enerin's Series A to decarbonise high-temperature industrial heat

Enerin, a Norwegian industrial heat pump technology company, has completed the third tranche of its Series A round, adding Paris-based Ring Capital to its investor consortium. The round includes Climentum Capital, The Footprint Firm, Johnson Controls, Move Energy, PSV Hafnium and Momentum. The company's HoegTemp system delivers thermal energy at temperatures up to 250°C, targeting the industrial heat segment responsible for over 20% of global CO2 emissions. Each installation avoids approximately 36,000 tonnes of CO2 equivalent over its lifetime by replacing fossil-fuel boilers. Enerin is transitioning from development to serial production, with three active pilots and a recent contract with Roche. The funding will scale manufacturing operations and accelerate product development. CEO Arne Høeg said Ring Capital's involvement strengthens the company's ability to deploy solutions across Europe.
