SorTech develops energy-saving, environmentally friendly adsorption chillers, which use excess heat as their primary energy source, e.g. from solar energy or industrial heat waste. The process involves the adsorption of steam from Zeolith, a sorption material, which results in the release of cooling. The unique technology can be deployed in a cost-efficient manner for many fields of application, e.g. for air-conditioning units, mobile cooling units, heat pumps, and vehicle air conditioning. The company sells products through its own sales department and also delivers application-specific products to OEM partners.
