REMKO KWG 505-1755 SERIES

In a modular design

The units of the KWG 505-1755 series, with an output range between 49.7 and 173.5 kW, are particularly compact and quiet, air-cooled chillers for outdoor installation. The units of the KWG series can be optionally configured with various hydraulic equipment, thereby enabling an optimum adaptation to the respective application.

In addition, the units have state-of-the-art, energy-efficient EC fans in the standard version. These fans provide considerable cost savings in comparison with conventional AC technology, especially in the partial load range. The interaction from the optimisation of the heat exchanger surfaces, use of highly efficient components and the optimisation of all operation-related system parameters ensure that the units have a very high degree of efficiency and therefore correspond with the pertinent requirements of the Eco-Design Directive.

  • Hydraulic components individually configurable
  • Multi-stage power control
  • EC fans, standard version
  • Floating switch contacts for integration into a building control system
  • Modbus data protocol, standard version
  • Extensive accessories for individual unit configuration
  • Units are ErP-compliant according to the Eco-Design Directive
