Better chillers - from the inside out
The constant innovation in chiller design is driven by new demands for energy efficiency, local regulations and standards such as LEED, combined with requirements for new, low GWP refrigerants.
Increasing population, level of comfort and high penetration of IT technologies are putting strong pressure on electric grids and driving up overall energy consumption.
The next generations of chillers and HVAC for new builds as well as retrofits are designed to meet new standards. The revolution in the A/C market opens up new opportunities. To meet the needs of an increasingly complex HVAC market, our extensive range of components offer functional benefits and savings throughout the lifecycle of the chiller system from development and operating costs to servicing and maintenance.
Danfoss can offer different options for meeting these requirements in air-cooled and water-cooled chillers, using scroll, centrifugal or screw technology, with excellent technical support from our expert teams. Compressors can be configured as tandems, trios or using inverter or Turbocor technology. With our electric expansion valves, controllers and sensors we can supply you with the right solutions for a highly efficient air conditioning system that responds quickly to variable operating conditions ensuring constant user comfort.
