CAREL manufactures control solutions for air conditioning, refrigeration, heating, humidification, and evaporative cooling, serving as a specialized controls and humidification manufacturer rather than an equipment OEM. 

Their product range spans programmable controllers (pCO range) for chillers, heat pumps, and air handling units, specialized HVAC controls, isothermal and adiabatic humidifiers (including immersed electrode, resistive steam, gas-fired, and ultrasonic humidification technology), reverse osmosis water treatment systems, and IoT digital services for remote monitoring and energy optimization. 

CAREL's humidification and controls technology is widely specified in hospitals, operating rooms, museums, data centers, and food retail applications where precise environmental control is critical, and the company has continued expanding through acquisitions including Cotes, a leading dehumidification solutions provider.
