As a result of many years of research and development activities, we have developed our own refrigeration adsorption unit, which can offer cooling capacities from 35 kW to 600 kW per 1 unit. The devices can be combined, achieving more than 1 MW of cooling capacity. The adsorption chiller can be powered by waste heat or other heat and is characterized by much lower electricity consumption compared to a compressor device with the same cooling capacity. The unit supply temperature ranges from 60°C to 95°C, and the chilled water temperature is customizable from 5°C to 20°C.
