MEA/K 15÷151

Condenserless liquid Chillers and Heat Pumps with Rotary/Scroll compressor and plate exchanger

The liquid Chillers and Heat Pumps for remote condensation of the MEA/K 15÷151 series, with R410A refrigerant, are designed for domestic or service sector systems which require medium power, space-saving units and quiet operation. Combined with remote condenser, these units are ideal for indoor installation and, equipped with a self-contained structure, they reduce the overall dimensions to a minimum while at the same time making installation and maintenance operations easier.
Equipped with prepainted plate structure, Rotary/Scroll compressor and plate exchanger, these units have cooling and hydraulic circuits designed for quick installation and high energy efficiency, even in the version with tank and pump.
A wide range of accessories, factory fitted or supplied separately, complete the outstanding versatility and functionality of the series.
