ECOi-RT-Z 105-140 H · R32 units are
available in 3 configurations:
· No damper: unit working with 100% recycled
air
· 2 dampers: with outdoor air inlet
· 3 dampers ‑ RECO system: energy recovery
system on the exhaust air. This configuration is
equipped with 2 return EC plug fans
116
· 2 refrigerant circuits for an optimised defrost logic,
completely closed in a separate compartment to reduce noise
level. Each circuit comprises of 1 Scroll compressor, indoor
and outdoor coils, 4 way reversing valve, filter dryer, sight
glass, thermostatic expansion valve, high and low pressure
switches, defrosting pressure switch, and temperature
sensors
· 2 Scroll compressors ‑ 1 per circuit ‑ covered with sound
jackets. Each compressor is equipped with a crankcase
heater and mounted on rubber pads to eliminate noise and
vibration transmissions. The motors are equipped with an
overload protection and have direct start‑up. A phase
sequence monitor is supplied as standard
· The new advanced control system includes, among others,
Modbus protocols, optimised defrost logic, very high security
envelope, Modbus control of the indoor fans, and a
dehumidification function. The controls are grouped and
wired in the unit, factory tested and shipped READY TO USE.
They are located in a sealed compartment isolated from the
air flow. The electrical equipment is compliant with EC
standards and EN60204‑1
· The outdoor and indoor heat exchangers are made of
seamless copper tubes mechanically expanded into
aluminium fins. They have a highly optimised design providing
a refrigerant charge reduction of 40% (compared to a unit
operating with R410A). Outdoor coils are largely dimensioned
to optimise performance and defrost cycles. They are also
equipped with a protective grille to prevent shocks ‑ Bluefin
treatment
· The unit casing is of heavy duty galvanized steel, painted with
a special anti‑corrosion process (RAL 9001). The complete
unit is covered with double skin panels to ensure perfect
thermal insulation. For full unit access, all service panels are
removable. Under the indoor heat exchanger, an extractable
condensate drain pan allows hygienic cleaning
· The indoor fans are plug fan type with EC motors
· A safety ventilation system ensures venting of the refrigerant
gas to atmosphere in case of leak
