LDE HA/SE/CO/P2U/Kr • Air cooled chillers on R454B

Chillers
Air/Water Cooling Only
EMICON
42 - 335 kW
R454B

Datasheet

Air-cooled chillers for the production of chilled water. The units are equipped with hermetic scroll compressors. Axial EC fans. Suitable for outdoor installation. Refrigerant R454B. These units are specially designed for cooling medium to large projects. Tandem technology offers multiple capacity stages and increases efficiency at part load. This also improves performance. Copper pipes and aluminium fins condenser coil with standard hydrophilic coating. Only sell to certified air-conditioning installers. Mandatory commissioning by CAIROX.
