The Danish company said its configurable CO2 system delivers up to 4.8 MW per unit and is scalable up to 50 MW for large industrial and commercial projects. The units offer hot water production up to 95 C and are compatible with complex installations such as food processing, district heating and commercial buildings.
Denmark-based Advansor has unveiled its SteelXL heat pumps, a configurable range of high-capacity CO2 heat pump systems designed for large-scale industrial and commercial applications. Individual units provide up to 4.8 MW of heat, with the option to scale up in parallel to more than 50 MW for larger projects.
“Thanks to their configurable options, SteelXL heat pumps enable rapid design and customized performance, even in the most complex installations,” a company spokesperson said. pv magazine. “They are fully configurable and designed for large-scale applications such as food processing, district heating and commercial buildings.”
The new heat pumps use R744 (CO2) as a refrigerant and are 18 m x 1.6 m x 2.26 m in size and have a weight of up to 33,000 kg, depending on the project configuration.
SteelXL units are offered in three standard sizes, with maximum heating capacities of 1.3 MW, 2.4 MW and 4.8 MW respectively, and minimum capacities of 600 kW, 1.2 MW and 2.4 MW. The units are reported to achieve a heating coefficient (COP) of 3.26–3.28 and a seasonal COP (SCOP) of 3.22–3.24, depending on the model. They provide hot water at temperatures up to 95 C, with a maximum inlet temperature of 60 C, and can operate in an evaporator temperature range of -10 C to 25 C and an ambient range of -14 C to 45 C, according to the manufacturer.
Electrically, the heat pumps are compatible with a three-phase power supply of 400 V/50 Hz or 460 V/60 Hz. Each unit has a receiver volume of up to 3,000 liters and can reach full power in just five minutes. For system integration, MODBUS TCP and RTU communication is supported.
Advansor said that to further improve efficiency, SteelXL units can be equipped with a range of energy saving features.
Parallel compressors can reduce the load on each unit, improving COP by approximately %, while cylinder shutoff technology optimizes part load performance, also increasing COP by approximately 5%. Furthermore, permanent magnet motors can minimize losses and increase the efficiency of both the motor and compressor, contributing an additional 5% to overall performance. Finally, the ejector technology increases the suction pressure on the compressors, optimizing both power and COP.
Founded in 2006, Advansor operates 15,000 m² of production space and 3,000 m² of warehouse facilities, with all production carried out in Denmark. According to its website, the company serves customers in more than 30 countries.
