The Mini Series Hi-Wall Indoor Unit brings together modern design, whisper-quiet operation, and efficient cooling performance in a single wall-mounted package. Slim, elegant, and unobtrusive — this unit is designed to complement contemporary interiors while delivering reliable, comfortable cooling for residential spaces, small offices, hotel rooms, and boutique commercial environments.
As part of the Water Cooled Mini DX system, the Hi-Wall unit combines the aesthetic appeal of a standard wall-mounted split AC with the efficiency and infrastructure advantages of a centralized water-cooled system — giving building owners and occupants the best of both worlds.
The Hi-Wall unit is available in three capacity options — 1 TR, 1.5 TR, and 2 TR — covering a cooling output range of 12,000 to 24,000 Btu/hr. This selection gives designers and installers the flexibility to match the unit precisely to the cooling requirement of each individual room or zone within the building. From a compact hotel room to a medium-sized office cabin or a spacious studio apartment — there is a Hi-Wall capacity that fits perfectly.
With an airflow range of 370 to 650 CFM, the Hi-Wall unit circulates room air effectively — ensuring fast temperature pull-down and consistent comfort throughout the space. The airflow is directed horizontally across the room from the wall-mounted position, creating natural air circulation that reaches all areas without creating uncomfortable drafts directly on occupants.
At just 33 to 38 dB(A), the Mini Series Hi-Wall unit operates at noise levels that are genuinely unnoticeable in most environments. To put this in context — 35 dB(A) is roughly equivalent to a quiet library or a soft whisper at close range. This exceptional acoustic performance makes the Hi-Wall unit the ideal choice for bedrooms, hospital patient rooms, meditation spaces, executive offices, and any environment where the quietest possible operation is a priority.
The Hi-Wall unit features a slim, low-profile wall-mounted body with clean lines and an elegant front panel that integrates naturally into modern interior design schemes. Unlike bulkier conventional wall units, the Mini Series Hi-Wall sits close to the wall and takes up minimal visual space — making it a subtle, unobtrusive presence in any room rather than an eyesore that detracts from the interior design.
The front panel is designed with aesthetics as a genuine priority — not an afterthought. The smooth, clean surface and refined finish complement contemporary residential and commercial interiors, making the Hi-Wall unit at home in premium hotel rooms, luxury apartments, and high-specification office environments where interior quality standards are high and every visible element matters.
Weighing between just 10 and 17 kg depending on the capacity selected, the Hi-Wall unit is among the lightest in its class. This lightweight construction makes wall mounting straightforward and safe — the unit places minimal load on the wall structure and can be installed quickly by a standard two-person team without specialist equipment. For large-scale multi-room installations, this ease of handling translates into faster project completion and lower installation costs.
The Hi-Wall unit's fan motor and controls consume just 55 to 95 watts of electrical power during operation — remarkably low for a unit delivering up to 2 TR of cooling capacity. This low auxiliary power draw contributes to the overall energy efficiency of the Water Cooled Mini DX system, keeping operating costs as low as possible for building owners and tenants throughout the cooling season.
Operating on a standard 230V single-phase power supply, the Hi-Wall unit requires no special electrical provisions and is compatible with the standard power infrastructure found in virtually all residential and commercial buildings across India. This universal electrical compatibility simplifies installation planning and eliminates additional electrical infrastructure costs.
The unit features reliable refrigerant connections with optimized pipe sizing — engineered to minimize pressure drop in the refrigerant circuit and maintain the system operating at peak thermodynamic efficiency. Properly sized and leak-free refrigerant connections are fundamental to both the performance and long-term reliability of any direct expansion cooling system, and the Hi-Wall unit is designed with this in mind from the ground up.
1 TR, 1.5 TR, and 2 TR — 12,000 to 24,000 Btu/hr — three capacity options for precise room-by-room sizing.
370 to 650 CFM — effective room air circulation for fast cooling and uniform comfort distribution.
33 to 38 dB(A) — ultra-quiet operation suitable for the most noise-sensitive residential and commercial environments.
55 to 95 W — exceptionally low auxiliary power draw for energy-efficient year-round operation.
230V, single-phase — standard electrical supply compatible with all residential and commercial premises across India.
10 to 17 kg — lightweight construction for easy, fast, and safe wall mounting installation.
Optimized pipe sizing with reliable sealed connections — engineered for low pressure drop and long-term leak-free operation.
The Hi-Wall unit is a natural fit for bedrooms, living rooms, and study rooms in premium apartments and villas connected to a Water Cooled Mini DX central system. Residents enjoy the familiar look and operation of a wall-mounted AC unit combined with the efficiency and clean exterior aesthetics of a centralized water-cooled system — no outdoor units on balconies or facades, no noise from compressors outside the window.
Hotel guests expect quiet, comfortable rooms with simple, intuitive climate control. The Hi-Wall unit's ultra-low noise level, elegant appearance, and straightforward operation deliver exactly the guest experience that premium hospitality properties demand. Its lightweight construction and standardized connections also make large-scale room-by-room installation in hotel fit-out projects fast and cost-efficient.
Individual office cabins, small meeting rooms, and executive suites benefit from the Hi-Wall unit's precise capacity options, quiet operation, and clean visual presence. The ability to control each room independently — with its own thermostat and on-off control — gives individual occupants personal comfort control without affecting adjacent spaces.
Medical consultation rooms, therapy rooms, and small clinical spaces require air conditioning that is completely unobtrusive — both visually and acoustically. The Hi-Wall unit's near-silent operation and clean design make it a genuinely suitable choice for healthcare environments where patient comfort and clinical professionalism are equally important.
