1.Twin system water cooled screw chiller 

Mgreenbelt Twin system water cooled chiller range – 50 TR through 500 TR - is designed for a 20-year operating life, with the lowest lifetime operating costs in the market.

Oil-free, flooded shell-and-tube evaporation, low power consumption, low maintenance costs (even lower with remote monitoring) and high reliability with only one main moving part.

Mgreenbelt works hard to achieve simplicity of design and operation – reflected in low operating costs and supported by the integration of the latest technologies in expansion valves and heat exchanger technology. Mgreenbelt controls enable stable and efficient operation at very low loads.

2.Serviceability

Always important in minimizing operating costs, service access is swift and simple, as is access to operating history through remote monitoring. Operating history, compressor and chiller set points are all accessible remotely by trained and authorized service personnel.

Integration through PLC or MODBUS with building management systems is standard, as is connectivity with most industry-standard protocols.

3.Custom design and production capacity

Mgreenbelt design engineers are happy to resolve special equipment design challenges for you, but please allow some extra time and, possibly, some extra cost for these.

High-efficiency direct expansion condensing units, heat recovery and free cooling applications can all be supplied competitively, as can special materials for use in aggressive environments.

Marine water boxes, corrosion protection and other options are available and can be explored on request.

4. Redundancy

Use of multiple compressors allows unusual redundancy safeguards; however, if multiple circuits are indicated, these can be designed in and supplied.
