EREBATM He Reversible air-to-water heat pump The new EREBATMHe air-to-water reversible heat pumps,These units integrate the very latest technological innovations: with Inverter technology, have been designed for residential R410A refrigerant fluid which does not contribute to ozone applications and for small commercial installations. They offer depletion, Twin Rotary DC Inverter compressors, a low-noise excellent energy efficiency and exceptionally quiet operation. fan with an electronic control. ErP Ecodesign is the European environmental design directive, aimed at improving the energy efficiency of energy-related READY products (ErP) through regulation. Ciat supports initiatives to reduce the environmental impact of its products. Specifications ■ A vast operating range, both in cooling and heating mode, offering great performance across a broad range of temperatures. ■ Twin Rotary DC Inverter compressors with pulse amplitude modulation (PAM) and pulse wave modulation (PWM) for increased reliability, reduced energy consumption and operation without vibrations, whatever the operating conditions. ■ Variable speed fans with a patented innovative blade shape, ensuring better distribution of air at exceptionally low sound levels.
