ARV7 technology
Enhanced vapour injection scroll compressors improve part-load efficiency and heating capacity at low outdoor temperatures, with no oil balance pipe between modules.
Turbo, basic and high-efficiency modes change the evaporating and condensing temperatures to tune for fast response or lowest energy use.
If a module or a compressor fails, the rest of the combination keeps running while a repair is arranged. Any module can act as master.
Fan static pressure of up to 70 Pa (8 – 22 HP) or 80 Pa (24 – 36 HP) allows outdoor units to be installed inside a service floor or plant room with ducted air.
Twelve silent levels, six for day and six for night, intelligent defrosting, and a 40 – 100% power-limiting function in seven steps.
Connects directly to the CC-02 central controller or a BACnet or Modbus building management system with no mini gateway.
Indoor units
220 – 240 V single phase unless stated. Any mix of indoor units can be combined on one system.

Controls and support
Wired controller XK-06A with timer, or an infrared remote, for each room. The CC-02 central controller runs up to 64 systems and 256 indoor units, with BACnet IP and Modbus gateways, a Wi‑Fi module for app control, and billing software with smart meters for multi-let buildings.
AHRV heat recovery ventilators bring in fresh air while recovering heat from the extract. Refrigerant leak sensors are available for occupied rooms.
For every project we prepare the outdoor and indoor unit selection, branch pipe schedule and controls specification, and supply the AUX VRF technical catalogue with full performance data, piping limits and wiring details.
FAQs
Quick answers about AUX VRF systems for consultants, contractors and building owners.
Variable refrigerant flow (VRF) connects one outdoor unit, or a bank of modular outdoor units, to many indoor units on a single refrigerant circuit, with every room controlled on its own.
Mini VRF, 8 to 18 kW in single and three phase, is for homes, shops and small offices. Modular Mini VRF combines 22 to 34 kW three-phase modules into one system of up to 36 HP for medium-sized commercial buildings. ARV7 modular VRF, with 8 to 36 HP modules and systems up to 144 HP, is for offices, hotels, schools, healthcare and retail.
Up to 61 indoor units on a single 36 HP ARV7 module. Indoor unit capacity can be up to 130% of the outdoor unit as standard, with larger ratios on request, and any mix of indoor units – from 1.5 kW wall units to 56 kW high static ducts – can be combined on one system.
ARV7 allows up to 1,000 m of total refrigerant piping per system and height differences of up to 110 m between outdoor and indoor units. Modular Mini VRF allows up to 560 m of total piping and a height difference of up to 50 m.
Yes. ARV7 connects directly to the CC-02 central controller, or to a BACnet or Modbus building management system, with no mini gateway. The CC-02 runs up to 64 systems and 256 indoor units, with BACnet IP and Modbus gateways, a Wi‑Fi module for app control and billing software for multi-let buildings.
