When the Space Demands Maximum Output

A 500㎡ banquet hall needs cooling you can count on — not hope for. The DeTong KF-24GW 24,000 BTU mini split AC is engineered for large commercial and industrial spaces up to 70㎡ per unit, delivering the highest cooling capacity in the DeTong wall-mounted lineup. At its core is a heavy-duty LG T1-rated rotary compressor built for 24/7 continuous operation — not intermittent duty, not peak-only, but the kind of sustained output that keeps a supermarket frozen-food aisle cold and a wedding hall comfortable from setup to last dance. The gold-plated FIN anti-corrosion system, industrial-grade chassis (43KG outdoor unit, 11KG indoor unit), and comprehensive compliance certifications make this the unit specifiers request for mission-critical cooling.

Maximum Capacity, Precise Control

◆ 6 Fan Speeds — The Widest Range Available: From whisper-level circulation (Speed 1) to full-force cooling (Speed 6), the 6-speed fan system provides granular control unmatched by standard 3-speed units. In a 70㎡ space with mixed occupancy zones, you can fine-tune airflow without overshooting the setpoint.

◆ 4D Air Deflection for Large-Area Coverage: Four-directional airflow with 100° horizontal and 90° vertical sweep ensures no dead zones in irregularly shaped commercial floors. This is critical for worship spaces with high ceilings, supermarket aisles with tall shelving, and L-shaped banquet halls.

◆ 40 dB(A) at Full 24K BTU Output: Achieving this noise level at maximum capacity required a complete acoustic redesign of the fan assembly — wider blades at lower RPM, a resonance-dampened motor mount, and airflow-optimized louver geometry. A 500-guest wedding reception won't hear the AC.

◆ Advanced ECO Optimization for Commercial Budgets: Unlike residential ECO modes that simply cycle off, the KF-24GW's commercial ECO algorithm modulates compressor frequency (in inverter variants) or duty cycle (in on-off variants) based on real-time thermal load analysis. This translates to 20-35% energy savings during partial-occupancy periods — significant when running 16 hours daily.

◆ 24-Hour Programmable Timer with Multi-Event Scheduling: Set up to 4 on/off events per day. Example: Cool to 22°C 8 AM-12 PM → ECO maintain 25°C 12 PM-4 PM → Full cool 22°C 4 PM-10 PM → Off overnight. One-time programming, automated execution.

◆ 3-Second Rapid Heating: When a convention center needs winter morning warmth or a warehouse requires freeze protection at dawn, 3-second heat activation eliminates the cold-start delay that frustrates facility managers and occupants alike.

Industrial-Grade Engineering

◆ LG Rotary Compressor — Continuous Duty Rated: This is not a residential compressor scaled up. It's a purpose-specified commercial-grade LG rotary compressor rated for 24/7 operation at T1 tropical conditions (52°C sustained ambient). Factory test data confirms full-rated output after 5,000 hours of continuous operation — equivalent to 7 months of non-stop summer duty.

◆ Gold-Plated FIN Anti-Corrosion — Mission-Critical Protection: The heat exchanger is the AC's most vulnerable component. Our gold-alloy electroplating process creates a molecular-level barrier that resists salt spray (coastal installations), acidic industrial atmospheres (factory-adjacent sites), and freeze-thaw cycling (high-altitude locations). Accelerated life testing demonstrates 3× longer fin integrity versus industry-standard uncoated aluminum. Sustains rated heating output at -25°C ambient.

◆ Heavy-Duty Physical Construction: Indoor unit: 970×310×230mm, 11KG net — the largest and most robust indoor unit in the DeTong range, built to withstand high-traffic commercial environments. Outdoor unit: 820×318×597mm, 43KG net — the compressor and condenser coil assembly is mounted on vibration-isolated rails within a powder-coated galvanized steel chassis. Wind load rated for rooftop installation.

◆ Refrigerant Flexibility: Available factory-configured for R410A (standard) or R32 (low-GWP, 68% lower carbon footprint). R32 also offers approximately 5% higher energy efficiency at equivalent capacity due to superior thermodynamic properties. Documentation provided for green building certification credits.

◆ Full Compliance Package: ISO 9001 certified production line with statistical process control. CE marking with full technical file. RoHS compliance for all materials. Every unit undergoes a 60-minute factory run-test (extended from the standard 45 minutes for the flagship model). Third-party quality audits available upon request for bulk procurement.

Engineered for These Environments

◆ Banquet Halls & Wedding Venues: 500㎡ hall with 20-foot ceilings. Cooling load: 400 guests + catering heat + audio-visual equipment. Design calls for 7 KF-24GW units in zoned configuration. Each unit covers 70㎡ with reserve capacity for peak occupancy. 40dB operation preserves ceremony audio and dinner conversation.

◆ Supermarkets & Department Stores: Open floor with gondola shelving creating airflow obstacles. 4D deflection system reaches around shelves. ECO mode reduces total store electrical load during weekday morning low-traffic periods.

◆ Places of Worship: 300㎡ prayer hall with occupancy varying from 20 to 300 people between services. Multi-event timer programming aligns cooling with service schedules. Quiet operation maintains reverence. Gold-plated FIN protection handles coastal or industrial location challenges.

◆ Convention Centers & Event Spaces: Modular venue with movable partitions. KF-24GW units installed per zone, independently controlled. 3-second heat activation for early-morning winter event setup. Robust construction withstands frequent reconfiguration and equipment movement.

◆ Light Industrial & Warehouse: 70㎡ workshop section with machinery heat load. Continuous-duty compressor handles 16-hour operation days. Tool-free filter access allows weekly cleaning by floor staff without interrupting production.
