Ductable Split AC 5.5 TR (66,000 BTU/h)
Project-grade cooling for banquet halls, restaurants and office floors: 66,000 BTU/h from a scroll compressor, distributed as 3,740 CMH through a professionally designed duct network. Every table gets the same comfort.
Share :
The Blue Star DSA661R3Q carries whole commercial floors — banquet halls, restaurant dining rooms, gyms, open offices of roughly 450–650 sq ft — on a single concealed machine. Air travels through a designed duct network to every corner, so the far table is as comfortable as the near one.
Its 66,000 BTU/h of cooling comes from a hermetically sealed scroll compressor — the technology Blue Star pioneered in ducted systems — pushed by a DIDW blower built for quiet, long duct runs. The condenser works at outdoor temperatures up to 50°C, and the electricals tolerate 360–440 V.
The intelligent controller provides auto restart after outages, fault display, ±1°C control and phase protection, while Blue Fin coils and the powder-coated GI body shrug off corrosion. Includes a 1-year warranty; Aircon Nepal provides heat-load calculation, duct and diffuser design, installation and lifetime service support.
TOP FEATURES
• Fully concealed above the false ceiling — a true central-AC experience with only grilles and diffusers visible
• Designed to operate at ambient temperatures as high as 50°C without tripping
• DIDW forward-curved centrifugal blower delivers strong, quiet, ducted air to every corner
• Bird-wing high-efficiency condenser fan lowers noise levels and running cost
• Intelligent microprocessor controller with LCD — auto restart, fault display, compressor time delay and accurate ±1°C control
• Single-phasing and phase-reversal protection, plus provision for fire-alarm input
• Blue Fin condenser and powder-coated, corrosion-resistant GI steel body
• Wide voltage range of operation (360–440 V) suits fluctuating three-phase supply
• Hydrophilic-coated evaporator fins and fire-retardant EPE insulation
• Cleanable non-woven polyester filters in HDPE mesh and a service-friendly layout
• Warranty: 1 year against manufacturing defects
