The double skin packaged Roof Top units of this series are the ideal solution for air conditioning of wide surfaces such as shopping malls and restaurants, canteens or for industrial areas. Those units feature Inverter Scroll compressor with R410A refrigerant and EC Inverter Plug-Fans. The highest efficiency at partial loads is guaranteed by the Inverter Scroll technology on compressor since its power is varied proportionally to the requested thermal load.
Equipped with extruded aluminium alloy sections and 50mm-thick sandwich panelling, these units are available in Cooling only and Reversible Heat Pump version.
The flat or pocket filters help to keep the air quality at a suitable level in order to guarantee appropriate hygiene standards.
The units are compliant to the ErP Regulation.

Versions

  • RTA/IK/EC - Cooling only with EC Inverter Plug-Fans
  • RTA/IK/EC/WP - Reversible heat pump with Plug-Fans EC Inverter

Power range

  • 58.0-252 kW
  • 17.0-72.0 Ton

Features

  • Structure of base perimeter made of steel sheet elements galvanised. Frame made of extruded aluminium alloy profiles connected by 3 way joints. Assembling of the base to the frame is of dual support and grants the walking on the base panels installation without sticking out screws. 50mm thick sandwich panels made of prepainted steel sheet; water proofing granted by gaskets having shape memory for perfect seal up even after repeated removals. Section connection is effected by means of assembling conic stirrups and water proofing is granted by gaskets.
  • DC INVERTER Scroll and ON-OFF Scroll compressors with oil sight glass, internal overheat protection and crankcase heater.
  • Condenser and evaporator with copper tube and aluminium finned coil.
  • EC INVERTER PLUG-FAN delivery fan with high energy efficient reversed blades with external rotor motor and electronic speed adjustment for easy adaptation to plant features.
  • Electronic expansion valve.
  • R410A refrigerant.
  • Electrical board includes: door interlocking isolator, fuses, thermal protection relays on compressors, thermocontacts for the fans of the condensing unit and contactors for the fan motors of the air handling unit.
  • Electronic proportional device to decrease the sound level, with a continuous regulation of the fan speed. This device also allows the cooling functioning of the unit by external temperature till -20°C.
  • Microprocessor for the automatic control of the unit.
