1.1.5 Technical specifications

These units are supplied completely factory-assembled and with all coolant tubing and wiring ready for
installation on site. After mounting, these units must go through an operational test with water. Coolant
leaks will also be checked during this process.
Sheeting cover
The units are made of galvanized steel sheeting and anticorrosion nuts and bolts. Panels can be removed
for access to internal components. The casing parts are painted with white RAL9001 oven-baked
polymerized enamel.
Compressors
One, two or four hermetic Scroll compressors are used, mounted in tandem on rails and antivibratory
supports. The compressors are connected for operation with one single cooling circuit. Start-up is carried
out by two independent starters. These compressors are equipped with mechanical elements that protect
them against high operating temperatures. The sump heaters operate only when the compressor is
inoperative.
Water-side exchanger
Comprises a stainless steel plate exchanger, adequately insulated by a layer of closed-cell elastomer
foam. Includes an antifreeze heater monitored by the controller. The coolant side of said exchanger
accepts an operating pressure of 45 bar, whereas the water side accepts 10 bar. When the unit includes
a hydro kit, maximum admissible pressure on the water side is 6 bar (adjustment of the tank safety valve).
Air-side exchanger
Made up of two notched aluminium blue fin coils and grooved copper tubing mechanically expanded
within the fin assembly.
Fans
The fans are connected to one plenum and have sufficient pressure available for accessories or to
connect them to ducts.
