Chiller with low GWP refrigerant R513A - AQUARIUS Plus 2
At this year's Chillventa in Nuremberg, MTA Germany is showing the proven AQUARIUS Plus series with the refrigerant R513A.
AQUARIUS Plus are water cooled chillers with semi-hermetic screw compressors and nominal cooling capacities from 377 to 1931 kW, which are also available as heat pumps and compressor-evaporator units.
As an alternative, R513A replaces the refrigerant R134a, which in medium term is also affected by the phase-down of HFC refrigerants as part of the F-Gas Regulation (EU Regulation No. 517/2014).
With the introduction of the low-GWP refrigerant R513A, the water-cooled chillers of the AQUARIUS series are the future-proof solution for large process refrigeration and air conditioning applications. Continuous power control, electronic expansion valves and highly efficient heat exchangers with integrated heat recovery help to achieve optimal seasonal efficiencies - both at full load and at partial load.
Extensive standard features
By default, all AQUARIUS chillers are equipped with shell-and-tube evaporators, crankcase heaters and electronic expansion valves. Operational safety is maximized with phase monitoring, automatic circuit breakers for the compressors, and check and shut-off valves in the pressure lines.
The chillers are controlled via the user-friendly interface of the xDrive microprocessor controller, which can be connected via the Modbus protocol RS485, via Ethernet interface or the xConnect specially developed by MTA for remote monitoring and parameterization.
