NECS-ME 1. PRODUCT PRESENTATION Introduction 1.7 Ease of installation This section contains general information on the NECS-ME All the connections of the NECS-ME units are located on the range of products. For detailed information refer to the specifi c side in order to simplify installation operations. This feature sections in this bulletin.
NECS-ME 2. UNIT DESCRIPTION Liquid chiller with remote condensation - remote ON/OFF terminals Water-cooled indoor unit for producing chilled water, with con- - spring terminals nection to a remote condenser fi tted with hermetic rotary scroll - pump enable relays (only for units without a standard hydronic compressors running on R410A, braised-welded plate exchang- unit) ers and a thermostatic expansion valve.
NECS-ME 2.4 Controller The controller is available in two formats: - HP and LP gauges - W3000 Base: keyboard and LED display. High and low pressure gauges (only for sizes 0152..0612). - W3000SE Compact: the keypad features functional controls Allows immediate reading of the pressure values on both low and a complete LCD display that allows assessment and inter- and high pressure circuits.

This allows the control unit interface to be cho- sen to suit the country of destination or, thanks to English, to be Remote keyboard completely independent for all geographical areas.
NECS-ME OPERATING RANGE Tev OUT [°C] Tc OUT [°C]: Heat exchanger temperature on source side (out) Limits to exchanger water temperature are valid within the minimum Tev OUT [°C]: Cold exchanger temperature on user side (out) - maximum water flow range indicated in the Hydraulic Data section. ETHYLENE GLYCOL MIXTURE Ethylene glycol and water mixtures, used as a heat-conveying fluid, cause a variation in unit performance.
NECS-ME HYDRAULIC DATA 5.1 Water flow and pressure drop Water flow in the heat exchangers is given by: Pressure drop is given by: Q=Px0,86/Dt Dp= K x Q /1000 Q: water flow (m Q: water flow (m Dt: difference between inlet and outlet water temp. (°C) Dp: pressure drop (kPa) P: heat exchanger capacity (kW) K: unit size ratio...
