Industrial heat pumps can be used to deliver hot air, water, or steam for industrial processes. Industrial applications generally require higher input temperatures than residential applications, and often utilize waste heat recovered from other processes, such as cooling data centers, or from wastewater.
Most industrial heat pumps have a capacity in excess of 100 kW and are capable of providing heat up to 150°C. They usually have screw or reciprocating compressors and utilize a wide range of refrigerants, including R717, R134a, R1234ze(E), R744 and R245fa. Compact, reliable, and highly efficient, SWEP brazed plate heat exchangers are the ideal components for modern heat pumps.
The industrial sector utilizes both low-temperature and high-temperature heat. Critical industries such as food, pharmaceutical, and chemical manufacturing usually require temperatures lower than 100°C. This range is ideal for heat pumps, which generally have an upper temperature limit of approximately 150°C.
The food and beverage sector requires low-temperature cooling, and heating simultaneously, making it a good fit for industrial heat pumps.
General industry, including mechanical and chemical industries, can utilize heat pumps to recycle waste heat from manufacturing processes to generate space heating and hot water.
In district heating, heat pump technology can be utilized to reclaim low-temperature waste heat and channel it into the district heating grid.
Heat pumps with a temperature range up to 200°C are currently in development, with limited availability on the market today. Heavy industry such as steel and cement manufacturing, however, demands temperatures beyond the range of heat pumps.
