Arc Duct 199mm Profile Ducted Unit
Ultra-slim silhouette meets C-form coil engineering and steady-airflow assurance for projects where every millimeter of plenum depth counts.
Ceiling plenum depth is the overlooked constraint that silently kills project timelines. When architects fight for every centimeter of finished floor-to-ceiling height, the ducted unit must be the slimmest component in the stack. The Midea V8 Arc Duct answers that challenge with a uniform 199 mm body height across the entire capacity range and a mere 450 mm front-to-back depth—dimensions that allow installation between standard structural beams, inside tight retrofit cavities, and above low-drop suspended ceilings where competing ducted units simply cannot fit.
The C-form heat exchanger is the engineering centerpiece: a continuous-bend coil geometry that eliminates seam joints where condensate pools and dust accumulates. Water evacuates rapidly and completely; particulates have nowhere to lodge. The result is a heat exchanger that stays cleaner longer, drains more thoroughly, and extends maintenance intervals—a tangible operating-cost benefit for building owners. Combined with constant-airflow logic that auto-compensates for duct friction and filter loading, the Arc Duct delivers design-intent performance from first commissioning through end of life.
Core Highlights
Uniform 199 mm Envelope Across All Capacities
Every model in the Arc Duct lineup shares the same 199 mm vertical envelope regardless of cooling capacity. This uniformity eliminates the guesswork in plenum design—specifiers can standardize ceiling depths across mixed-capacity zones without worrying about taller units in larger sizes.
450 mm Depth for Beam-to-Beam Installation
The shallow 450 mm chassis depth enables placement between standard structural beams and in narrow plenum corridors where depth is the binding constraint—unlocking ducted VRF in buildings previously limited to high-wall or cassette-only solutions.
C-Form Coil: Seamless Drainage, Zero Particle Traps
The continuous-bend C-shaped coil eliminates seam joints and crevices that trap condensate and dust in traditional flat-coil designs. Water sheets off smoothly; particulates cannot anchor—reducing cleaning frequency and extending coil heat-transfer efficiency over the equipment's service life.
Steady-Airflow Compensation Logic
An embedded airflow regulation algorithm continuously adjusts fan output to offset duct resistance changes, filter loading buildup, and outdoor-condition variability. The supply volume delivered at commissioning is the same volume delivered years later—no field re-calibration needed.
Right-Angle Service Orientation
The unit supports orthogonal installation alignment with service panels oriented for straightforward field access. Filter swaps, motor inspection, and drain-pan cleaning are achievable without dropping the unit from its ceiling position—minimizing maintenance disruption to the space below.
1,200 mm Drainage Head with Fault Signaling
The standard high-lift pump includes digital anomaly detection: if impeller RPM deviates from expected curves or flow rate drops below threshold, the controller issues a pre-emptive fault signal—giving facility teams a maintenance window before any water escapes the drain path.
Selectable Long-Life or Mid-Grade Filtration
Two filtration tiers let specifiers match the filter to the environment: long-life media for low-maintenance access scenarios, mid-grade media for spaces requiring elevated particulate capture—without changing the unit chassis.
