  • Page 5: Presentation Of The Unit

    GENERAL SPECIFICATIONS Presentation of the unit This new series of industrial chillers and heat pumps has been designed to meet the demands of global markets in the medium-big power industrial and commercial plants. Units are compact and highly configurable, built to fit different types of plants so to meet the needs of highly qualified engineers.
  • Page 6: Description Of The Components

    GENERAL SPECIFICATIONS Description of the components 1. Fans. These are the helical type with scythe-shaped blades to increase the efficiency and reduce the noise level. The fans are directly coupled to the single-phase motor by means of an external rotor. Thermal protection against operating faults is installed insi- de the winding.
  • Page 7 GENERAL SPECIFICATIONS 7. Condensing coils, the aluminium finned pack type with shaped profile to increase the heat exchange coefficient and with copper pipes arranged in staggered rows. A sub-cooling section is integrated into the lower part. 8. Covering panels, made of galvanized sheet metal coated with polyurethane powder paint to ensure maximun protection against adverse weather conditions 9.One-way valves (IP unit only), allowing the coolant to pass into the appropriate exchangers, depending on the operating cycle.
  • Page 8: Version With Desuperheater Vd (Available For Both Ir Units And Ip Units)

    GENERAL SPECIFICATIONS Version with Desuperheater VD (available for both IR units and IP units) Hydraulic and chilling circuit components: 1. Desuperheater. Specially designed for the specific version. Plate type, made of stainless steel (AISI 316). There are installed within a shell of thermal barrier insulating material to prevent heat exchanges towards the outside. Standard supply also includes an electric antifreeze heater to prevent the parts from freezing during the winter, when the system remains at a standstill (if not drained).

  • Page 52: Air Vent And Water Drain

    HYDRAULIC CONNECTIONS Air vent and water drain On the piping circuit feeding the unit, especially when equipped with the Victaulic connection kit, the installer must fit an appropriate number of valves (manual or automatic) at the top of the circuit in order to vent any air in the piping system. In the same way, he must install a water drain valve in order, when necessary, to drain the unit’s plate exchanger completely (especially during the winter in order to prevent freezing that would seriously jeopardize the operation of the unit).

    START-UP General Rules To validate the contractual warranty, the machine must be set at work by technicians from an authorized assistance center. Before they are called, check to make sure that all parts of the installation have been completed, the unit levelled, the wet connections made with the relative air vent and the electrical connections made.
  • Page 66 MAINTENANCE • Inspection of the condensing system wARNING: The finned pack exchanger has fins made of aluminium or some other thin material, thus even accidental contact could cause cuts. Comply with the instructions in the relative section. • Condensing coils In view of the function of this component, it is very important for the surface of the exchanger to be as free as possible from clogging caused by items that could reduce the fan’s air flow rate and, thus, the performances of the unit itself.
  • Page 67: General Considerations

    MAINTENANCE General considerations The machine has been designed with a view to reducing the risks to persons and the environment in which it is installed, to the mi- nimum. To eliminate residue hazards, it is therefore advisable to become as familiar as possible with the machine in order to avoid accidents that could cause injuries to persons and/or damage to property.
