Hiver offers a variety of MEG brine water-cooled screw chillers for a wide range of cooling capacities from 10 tons to 400 tons for process cooling applications with 0 deg.C to minus 40 deg.C low ultra-temperature, medium GWP HFCs R134a, R22, R404a and R407c refrigerant options.
Our MEG brine water-cooled screw chillers can reduce your total cost of ownership because they are engineering for lower life cycle costs and reliability through design simplicity. These systems are popular in many commercial & industrial applications such as chemicals, pharmaceuticals, food & beverages industries, etc. due to their distinct advantage of multiple refrigeration circuits with semi hermetic screw compressors or open type of compressors compactness and service-friendliness.
Our compressor technology is direct drive, low speed (3600 rpm) with only one rotating parts for high reliability and efficiency. Optimized compressor parts profiles are designed specifically for brine applications to optimize full and part-load efficiency. Our 'H Smart' fully automatic PLC based Controller provides greater reliability through a proactive control strategy, safety functions with simple diagnostics and easy interface with any building automation / energy management using RS485 or Ethernet / LAN connectivity. Hiver MEG brine water-cooled screw chillers are the right choice for right temperature control in virtually any brine chilling application.
These chillers comprise of DX or Flooded Evaporator, shell & tube condenser, electronic expansion valve and multiple semi-hermetic screw compressors, multiple stages with VFD & Cascade system options.
Electronic expansion valves are used to maintain precise flow of refrigerant to evaporator under both full load and part load operation of compressor. Exv can close positively and stop any liquid flood back to compressor.
MEG being non-flammable so that we are always provides chiller in single refrigeration skid.
