The Next Generation Multi Denco Units feature:
Fan Technology – Air movement is delivered using high efficiency EC fan technology with 7 backward curved, three-dimensional profiled blades made from high-performance composite material which deliver exceptional energy performance.
These fans use significantly less energy than conventional fan technology. EC technology allows continuous adjustment of fan speeds as required to support data centre cooling demands. Due to the “Cube Law” in N+1 mode the fans only need to operate at fraction of the normal mode operation. For example based on 25% load the fan energy curve is reduced to 1.56% of full speed energy (0.25 x 0.25 x 0.25).
Electronic Expansion Valves which decrease condensing temperature at low ambient temperatures enabling energy savings as compared to traditional thermostatic expansion valves.
Copper/Aluminium high-performance Heat Exchanger with corrugated fins which are designed for optimal air pressure drops.
Touchscreen Display Microprocessor Controls fitted with various interfaces for building management systems provide excellent flexibility supporting a wide range of applications.
Inverter speed-controlled scroll compressor adjusts to requirements with R-410A refrigerant for efficient operation.
