MTA Phoenix G Air-cooled Chiller

Chillers Phoenix G

The air-cooled chillers of the PHOENIX G series are equipped with tube bundle evaporators, electronic expansion valves, crankcase heaters and xDrive controllers as standard. Thanks to the "Smart Stepless" control, the cooling capacity can be precisely adjusted to the heat input into the system. The self-adaptive control continuously adapts the performance of the screw compressor to the requirements of the system.

Benefits

• Low GWP (Global Warming Potential) R513A refrigerant;
• High seasonal SEER energy efficiency values;
• Thanks to the unique MTA "smart-stepless" algorithm, the control adapts precisely to all operating conditions;
• Very reliable and continuous operation thanks to up to 2 screw compressors and "smart-stepless" system;
• Wide operating limits;
• Extensive safety equipment including phase monitoring, pressure switch, crankcase heaters, compressor overload protection and oil level monitoring;
• Can be optimally adapted to any system thanks to extensive accessories and kits.
