Presentation of the unit
This new series of industrial chillers has been designed to meet the air conditioning requirements of
medium-large systems in the industrial, service and business sectors. Suitable for outdoor installation, they
are built for various types of system and to comply with the needs of highly qualified planning engineers.
The complete series for use in hydronic systems includes 8 sizes with refrigerating power ratings ranging
from 136 to 299 kW and heating output ratings ranging from 165 to 350 kW. When the units were desi-
gned, particular attention was also paid to sound emission in our endeavour to comply with the increasingly
more restrictive laws governing acoustic pollution: all the sizes are therefore available in both the basic and
silenced versions, to choose depending on the noise level required.
All the units can produce cold water at a temperature between 5 and 10 C (summer operating mode) and
hot water from 35 to 55 C (winter operating mode). As part of the standard supply, they are pre-enginee-
red for summer/winter operation at low/high outdoor air temperatures thanks to use of a condensation/eva-
poration monitoring system through continuous control of the fans by steps. All the units are equipped with
2 independent chilling circuits, each of which has two Scroll compressors. This allows the power genera-
ted by the unit to be modulated from 25% to 100%, thus adapting to the heat load of the system supplied.
All the units are equipped with a thermal barrier plate type evaporator protected by means of a differential
water pressure switch and electric antifreeze heater, coils with extended surfaces and extensive heat
exchanging areas formed by copper pipes and notched aluminium fins, electric fans with scythe-shaped
vanes to reduce the sound emission, electric panel for adjustments and controls, controller with micropro-
cessor.
The standard supply can also be integrated with a vast range of electrical and mechanical accessories. The
Water Storage Tank and Pumping Module with 1 or 2 Pumps are particularly important accessories. If both
are chosen, the tank is configured for storage on the delivery to the system or for storage on the return part of
the system, or for storage pre-engineered for the primary and secondary circuit, depending on the type of
Pumping Module selected.
The chillers have been designed for use with R407C environment-friendly refrigerant.
All the units are accurately built and tested individually. Installation only requires electrical and wet connections.
