 | Air conditioning manufacturer Aermec has launched a new water-cooled chiller offering energy efficiency even at partial loads. The WMG is described as a compact chiller designed for indoor installation. It has high efficiency two-stage magnetic levitation centrifugal compressors, which allow the refrigerant circuit to be oil free. It also has a very low starting current and uses 50% less refrigerant thanks to its patented spray technology within the heat exchanger. In addition, the WMG delivers savings on installation and maintenance. |
offers high efficiency even at partial loads and has an EER rating of 5.4 and an ESEER rating of 8.4 - one of the highest in the market. The use of inverter technology in the compressor provides greater energy efficiencies, running costs, more accurate temperature control and improves the EER. The WMG’s performance is Eurovent certified.
Aermec says the WMG’s modular design and component layout simplifies installations. The units are five times lighter than screw compressors and can be transported through doorways and into lifts. Several modules can be positioned side-by-side, ideal in plant rooms with limited space, and also provide flexibility when a standby unit is required or when cooling duty needs to be increased at a later date. There is no need for critical spares as a standby module can be used as a spare chiller instead.
Each module is capable of 280kW – 324kW depending on the size of compressor used and is available as a standard unit or as a silenced version with a soundproof cowling.
A front mounted colour touch screen provides an easy user interface with an intuitive graphical menu and the built-in inspection door enables easy access for cleaning and maintenance of the heat exchangers.
Paul Lawrence, Managing Director of Aermec (UK), said: “Aermec is continually pushing the added value envelope and this latest chiller is no exception. The WMG shows how innovative design harnessed with environmental considerations can provide customers with greener solutions that are also cost effective.”
The WMG chiller operates with HFO refrigerant R1234ze which has a GWP of 6. The bearings are magnetic levitation type, vibration free and very quiet and the oil free compressors further reduce the environmental effects.

The WMG is also available in a silenced version for noise sensitive environments. Aermec also offers the WMX model which operates with R134a, this unit can also be silenced. Numerous options are available for both models offering customers a number of configurations to suit their requirements.
