NECS-FC-Y 0152 - 1604

Air cooled chiller with free-cooling 41,5 - 445 kW

Outdoor unit for the production of chilled water, equipped with hermetic scroll compressors, R410A refrigerant, axial-fans, condensing coil with copper tubes and aluminum fins, braze-welded plate evaporator and thermostatic expansion valve. External panels are of peraluman, base of galvanized epoxy powder coated steel. The unit is supplied with anti-freeze oil and refrigerant and has been factory tested. On-site installation therefore just involves making connections to the mains power and water supplies. These chillers, fitted with free-cooling coils, are used when the cooling load is constant all-year-round or the outdoor air temperature is lower than the temperature of the liquid return line. In free cooling mode, the liquid is cooled by outdoor air, thus lowering the load of the compressors until it is reduced to zero. The NG configuration complies with applications where it is not allowed or desired the use of ethylene glycol.

Features

FREE-COOLING

The generous size of the free-cooling coils allows to produce the nominal cooling capacity without the use of the compressors for many hours per year, thus cutting the annual energy consuption.

ENERGY SAVINGS

Energy saving guaranteed by free-cooling, which exploits the low external air temperatures; free-cooling control with optional modulating valve.

OUTSTANDING VERSATILITY

Units available in two different versions, B (basic) and SL (super low noise), in order to fully satisfy special requirements and comply with the most complex installation solutions.

CUSTOMISED CONTROL

Customised adjustment constantly guarantees the required temperature of the chilled water whilst fully exploiting all the available resources (compressors, fans and water coils) in relation to the temperature of the external air. This makes it possible to fully use the free-cooling system even when external air temperatures are close to zero.

INTEGRATED HYDRONIC GROUP

The built-in hydronic module already contains the main water circuit components; it is available with single or double pump configuration, with low or high head.
