MAIN
FEATURES
The use of a directly coupled motor substantially increases the yield from the heat dispersed into the air and the absorbed
power than that which can be obtained with fan systems featuring a drive belt, it also dramatically reduces the need for
maintenance intervention and guarantees total reliability.
The cooling coil has been designed with a large front surface in order to have an elevated SHR and a low air crossing speed
in order to eliminate droplets of condensation, reduce pressure drops in the air and ensure a more efficient heat exchange
during both the cooling and dehumidification processes. The coil is made from copper tubes mechanically expanded on
aluminium fins. The coil is situated upstream from the fans in order to ensure optimum air distribution and has a stainless
steel condensate drain tray with a flexible drainage tube and an integrated siphon.
The design of the Exchange coil allows an elevated SHR ratio
Box type air filters made from self-extinguishing, synthetic fibre cellular material. The frame containing the filter material
is made of metal. The pleated arrangement of the filters extends the surface area ensuring a high filtering efficiency and
low pressure drops. The filtering rate is EU4 (according to EUROVENT 4/5). It is extremely easy to access and remove
the filters in all unit configurations. The unit can be supplied with a high capacity (optional) filter for air renewal which is
connected to the outside by means of a flexible conduit.
Low airflow and clogged filter alarm sensors (standard on all models) consisting of two pressure switches for controlling
the operating conditions of the fans and the build up of dirt on the air filters inside the unit.
Hydraulic circuit (CW models)
The piping for the hydraulic circuit is coated entirely with closed-cell insulating material to class 1 according to DM
26.06.84, class 1 according to BS476 part 7, ASTM E 162-87, reduced fume opacity measured according to ASTM 662-79.
The unit can be fitted with a two-way or three-way valve with a remote controlled servomotor. The maximum pressure is
6 bar (PN6). Units with higher maximum pressures can be supplied on request.
Hermetic scroll compressors (air and water cooled DX models), featuring an elevated C.O.P (Coefficient of Performance)
and therefore high energy efficiency. Scroll compressors have the following features:
monitoring during operation, without having to switch the equipment off.
Refrigerant circuit (air and water cooled DX models)
Each circuit features:
increasing the life of the components), while the second allows a rapid check to see if the system is correctly charged
with refrigerant and whether is contains any humidity;
through the evaporator to be adjusted, controlling the real evaporator superheating in relation to changes in the ambient
conditions, increasing the precision of the cooling and the energy efficiency of the cooling cycle;
