Multi-DENCO
Precision climate-control units for constant temperature
The Multi-DENCO® range of precision climate-control units will replace the old Denco T and E ranges. In its precision climate-control field, Multi-DENCO® will be available in various model sizes, with 5 kW up to a maximum of 130 kW cooling duty. These units operate with the refrigerant R410A and, under typical conditions, operate with a sensible heat ratio (SHR) of 1. This signifies that Multi-DENCO® units can cool the air without at the same time dehumidifying it. In the recirculating-air mode of operation the units control air conditions at a stable level of ± 1 K and ± 5 % relative humidity. The possibilities of employing the units extend from computer centers and machine rooms with intensive production of exhaust heat, to measuring laboratories and art museums – for which not only a standard temperature but also constant relative humidity are critical.

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.
