Johnson Controls has launched its Sabroe HitemHP line of industrial high-temperature heat pumps for European industries requiring high-temperature process heat. The units deliver output temperatures up to 122°C (252°F) and use natural refrigerants.
The HitemHP range is engineered and manufactured at the company’s heat pump and chiller facility in Denmark. It uses the Sabroe SMC single-stage reciprocating compressor and can operate from 100% down to 18% capacity. Johnson Controls says service intervals can be extended by nearly 50%, while coefficient of performance (COP) can be up to 20% higher under part-load operation than at full capacity.
The heat pumps use ultra-low-GWP butane and iso-butane, which Johnson Controls says align with upcoming EU regulations. The range features a standardized, modular, configure-to-order design with compact, factory-assembled units intended to reduce lead times, installation complexity and commissioning time.
In one customer application based on site-specific operating conditions and assumptions, the system delivered up to three times the energy efficiency of electric boilers. When paired with waste heat from a refrigeration plant, it showed potential to reduce energy costs by more than 91%, annual water costs by up to 30% and on-site CO2 emissions by up to 82%.
“Until now, electrifying high-temperature heat has been one of the hardest problems to solve. With our new Sabroe high-temperature heat pumps, Johnson Controls is delivering a breakthrough solution that can help critical industries and institutions secure their energy future, significantly cut operational costs and align with the ambitions of Europe’s Clean Industrial Deal, driving the competitive advantage of our customers in cutting-edge industries,” said Steve Bell, vice president and general manager, Industrial Refrigeration, Johnson Controls.
