Envision® Series NKW
Overall efficiency, performance & features
Cooling COP 5.0 - 5.8 / Heating COP 3.5 - 3.7(BS EN 14511-2 BO/W35)
High volume hot water or chilled water | 30 to 150 kW
The NKW range of water to water GSHPs operate as a reversible chiller and replace the need for both chillers / cooling towers and boilers. They are an excellent choice to provide either chilled or hot water for a wide range of applications with potential for both simultaneous heating / cooling as well as great partial load capacity.
Applications include pools, commercial aquariums, radiant floor heating, ice melt, chilled water applications, industrial process water and space conditioning using fan coils. Being part of the Envision product range means that they are designed to perform to the highest standards in the industry.
Large in capacity but compact in size, these units will fit through most doors for easy installation. High efficiencies are obtained using scroll compressors — two are used in the dual circuited unit. Units are controlled using HydroLink Aurora controls which marry the field-proven Aurora compressor management with the HydroLink NiagaraAX-based system level controller to manage setpoint, control, staging, and the 10″ color touchscreen HMI tablet display while communicating over 200 points to the BAS network via BACnet, LonWorks, or through the NiagaraAX bus. The unit’s brazed plate heat exchangers are constructed with 316 stainless steel for long life. Non-ozone depleting R-410A refrigerant is used.
