RTQ/IK/EC 101÷181

Single or double skin packaged Roof Top units with Inverter Scroll compressor and EC Inverter Plug-Fan

_icona_clint_solo_raffreddamento-riscaldamento_2024.png

The packaged Roof Top units of this series are the ideal solution for air conditioning of medium surfaces such as shopping malls, restaurants and canteens. These units are equipped with Inverter Scroll compressor with R410A refrigerant, and are available in Cooling only and reversible Heat Pump version, also with Free-Cooling with 2 dampers. It is equipped with EC Inverter Plug-Fans, managed by an electronic control adjusting fans' rotational speed to adapt the air flow to the system capacity. For MS versions it is possible to connect an additional enthalpy wheel heat recovery module.

On request, units can be supplied with R454B refrigerant.
The units are compliant to the ErP Regulation.

Features

INVERTER Scroll compressor with oil sight glass, internal overheat protection, crankcase heater and soundproofing cover.
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.
Electrical board includes: disconnector switch with door lock; circuit breakers to protect each electrical utility (compressor, fans, etc.) contactors for the fan motors of the air treatment section and for the condensation fans; interface relays and push-in type terminals for easy and safe wiring including external customer connections.
Electronic proportional device: condensation control that allows the speed of the condensing-side fans to be adjusted according to the required load, allowing the sound level of the unit to be attenuated.
Microprocessor for the automatic control of the unit.
MS. Free-Cooling section with 2 dampers - Further to components of the basic version, includes two aluminium dampers with spring return servomotors (dampers with opposite movement).
Communication with Modbus RTU protocol through RS485 serial interface.
Structure of base perimeter made of steel sheet elements galvanised, passive treated and press-bent. The frame is made of extruded aluminium alloy profiles connected by 3 way joints. The perimeter panels are made of pre-painted sheet metal, easily removable, and allow access to the inside of the unit for maintenance. The panels on the air-handling side and condensate side are provided with insulation material. By selecting the DBK or DBK1 option, the unit will be supplied with 25 mm thick sandwich panels.
R410A refrigerant. On request R454B refrigerant.
