Outdoor heat pump for the production of chilled/hot water with hermetic rotary Scroll compressors, ozone-friendly refrigerant R410A, axial-flow fans, shell and tubes exchanger and electronic expansion valve. The range is composed by units equipped with four, six and eight compressors in multi-circuit configuration.
Set-up for remote connectivity with ModBus, Echelon LonTalk, Bacnet protocol board
Remote control keyboard (distance to 200m and to 500m)
LT kit for extending the operating limits in heat pump mode down to -10 °C (/SL-CA versions) and -12 °C (/CA versions)
REFRIGERANT GAS R410A
The use of R410A allowed to achive better energy efficiencies with environment full respect (ODP = 0)
The shell and tube exchanger allows to achieve the highest flexibility on the unit’s installation, keeping the efficiency at the maximum level. For this reason, NECS-N represents the best choice for all the hydronic application on the residential, commercial and industrial markets.
ELECTRONIC EXPANSION VALVE SUPPLIED STANDARD
The use of the electronic expansion valve generates considerable benefits, especially in cases of variable demand and different external conditions. It was introduced into these units as a result of accurate design choices concerning the cooling circuit and the optimisation of operation in various different working conditions
INTEGRATED HYDRONIC GROUP
The optional built-in hydronic module already contains the main water circuit components; it is available with single or twin in-line, for achieving both low or high head.
