The enhanced energy efficiency in em>Multi-DENCO® precision climate-control units is achieved first by an optimized configuration of heat exchangers and fans as primary components – for which the circulated air must overcome less air resistance in the unit. Second, the heat exchanger has greater dimensions. The resulting large air volume is likewise responsible for the stability achieved in temperature control. The inverter drive, which controls the refrigeration compressor variably and steplessly, adapts the unit output to the cooling demand – which results in high energy efficiency, especially in partial-load operation. The units from the Multi-DENCO® range are equipped with EC fans that feature very low power consumption. Since the units operate especially energy-efficiently under partial load, they are ideally suited as standby redundant systems.
The Multi-DENCO® range, all models of which are otherwise identical, offers five different cooling systems. The range was launched in winter 2012/2013 with the Version A, which operates with an air-cooled condenser. Version C is water-cooled, and Version X is equipped with a split direct evaporator. All three versions can be retrofitted with an additional cold-water heat exchanger to provide the CombiCool version. The water-cooled Version W can be expanded to a Version F by adding a free-cooling function.
The Multi-DENCO® precision climate-control units are available in various model sizes for a range of different room concepts. For all versions, the units reach a height of just under 2.0 m, and the footprint will range from 60 x 60 to 88 x 338 cm, depending on the model.
