NPE SERIES
MULTIPURPOSE MULTIFUNCTIONAL NPE SERIES 60 - 162 kW
The NPE units are multipurpose air/water units available for use with R290 refrigerant with low environmental impact. The NPE range is designed to manage the conditioning of industrial plants and thermal loads in technological applications where full 24/7 reliability in all working conditions is a requirement. The NPE range uses latest-generation Scroll compressors, braze-welded plate exchangers optimised for use with medium pressure refrigerants (R290) and axial fans suitable for outdoor installation.

Technical specifications
PLATE HEAT EXCHANGERS
The NPE range uses brazewelded plate exchangers with asymmetrical channels, suitable for the use of high and medium pressure refrigerant gases. The configuration with asymmetrical channels allows high heat exchange efficiencies to be reached while maintaining low pressure drops on the water side – which results in reduced pumping costs at both full and partial load.
SMART DEFROSTING
A factor that heavily weighs on the costs of managing the entire plant is finned coil defrosting during wintertime operation. The special management of the defrosting cycle of NPE units minimises the time to completion and ensures that defrosting is only performed when strictly necessary,guaranteeing greater heating efficiency.
The presence of two completely independent thermodynamic circuits ensures uninterrupted operation also during the defrosting phase, with practically no thermal discomfort for the user.
PRODUCTION OF HOT WATER UP TO 80°C
NPE series are capable of producing water at 80°C and operating at outside air temperatures as low as -20°C.
PRECISE MANAGEMENT OF THE DELIVERED POWER
The integrated control software of the NPE range allows for the management of cooling and heating power output by adjusting the rotational speed of the modulating BLDC compressors.
REDUNDANCY AND CONTINUOUS OPERATION IN ALL WEATHER CONDITIONS
The presence of two completely independent thermodynamic circuits ensures continuous operation even during the defrost phase, eliminating any thermal discomfort for the user.
