Self-supporting galvanized steel frame protected with polyester powder painting. Panels are easily removable for maintenance and service activities.
COMPRESSORS variable speed Hermetic “scroll inverter driven”, with overload protection by a klixon and complete with oil sight glass. They are
installed on vibrations absorbing rubbers.
Braze welded plate type with one or two independent refrigerant circuits and one water circuit. The circuit is made to guarantee an homogeneous cooling of all water flow even during partial load. The insulation is made of flexible closed-cells lining. As protection, a differential pressure switch is mounted to stop the unit in case of no water circulation.
Copper tube and aluminium finned coil. As option a protection grid is available.
(EC) INVERTER AXIAL FANS:
Condensing control included Axial fans with aerodynamic outline blade section, directly coupled to a three phase electric motor with external rotor. A
safety fan guard is fitted on air flow discharge.
Each unit is equipped with one or two refrigerant circuits. Each circuit includes: filter dryer, sight glass, Electronic thermostatic valve, Schrader service valve. To protect the refrigerant circuit following devices are installed: man. reset high pressure switch, aut. reset low pressure switch,
antifreeze thermostat. The Heat Pump Units version contain, in addition: safety thermostat on the discharge line, 4-way valve, non-return valve, two electronic thermostatic valves, liquid receiver and, if necessary, liquid separator on the compressor suction line.
With protection grade IP54 the el. board is mounted in the compressor chamber. Service activities can be done while the unit is in operation. It includes: main circuit automatic breaker with locking door device, compressors and fans contactors and relé, auxiliary circuit transformer.
Microprocessor to control automatically the unit with a visual system to display the function as well as failures.
Separate frequency-controlled inverter compressors mounted in special compartment.
