Overview
A VRF project succeeds or fails on its indoor units: they set the comfort, the noise level and the look of every room. We supply the complete indoor lineup for GCHV VRF systems so one supplier covers your entire schedule.
Indoor units span 2.2 kW to 28 kW across ten form factors — the compact cassette runs as quiet as 21 dB(A), while the high-ESP duct delivers 150 Pa of external static pressure for long duct runs. All DC-fan indoor units use electronic expansion valves on R410A.

Additional types — 1-way and 2-way cassettes, fresh air processing units and DX AHU modules — can be arranged on a project basis.
Applications
Paired with GCHV and Mini VRF outdoor units across hotels, offices, retail and residential projects.
These indoor units pair with both the GCHV VRF system (25.2–90 kW outdoor modules) and the Mini VRF system (8–16 kW single-phase outdoor units), within a 50%–130% indoor-to-outdoor connection ratio.

Packing & Delivery
Units are packed in cartons with wooden case or crate reinforcement engineered for sea freight and transshipment handling. Accessories, controllers and spare parts are consolidated into the same delivery, so your installer has everything on day one.
FAQ — VRF Indoor Units
Can different indoor types mix on one system?
Yes — cassettes, ducts, wall and floor-ceiling units mix freely on one outdoor unit within the allowed connection ratio.
How quiet are the VRF indoor units?
The quietest model is the compact 4-way cassette at 21 dB(A) sound pressure on low fan speed, followed by wall-mounted and low-ESP duct units starting at 24 dB(A). Mid-size units such as the 360° round-flow cassette run at 31–47 dB(A), and the largest high-ESP duct units range from 45 to 52 dB(A). Model-by-model sound data is available in the factory datasheets.
What static pressure options exist for ducted indoor units?
Three tiers cover different duct layouts: low-ESP units rated 30 Pa for 2.2–7.1 kW capacities, medium-ESP units rated 70 Pa for 7.1–15 kW, and high-ESP units rated 150 Pa for 20–28 kW with airflow up to 4,100 m³/h. All ducted units run on 220-240 V single-phase 50 Hz power, so no separate three-phase indoor wiring is needed.
What is the largest single VRF indoor unit?
The largest single unit is the high-ESP concealed duct model rated 28 kW cooling and 30.8 kW heating, moving 4,100 m³/h of air at 150 Pa external static pressure. Two smaller sizes, 25 kW and 20 kW, share the same 1440×811×448 mm casing. One large duct unit can replace several small units in banquet halls, open-plan offices and retail floors.
