One Unit, Every Room — Built for Versatility

The DeTong KF-12GW 12,000 BTU mini split AC fills the critical middle ground in any HVAC lineup. It's large enough to cool a hotel suite or family living room (up to 35㎡), yet compact and quiet enough to disappear into the background. Powered by an LG T1-rated rotary compressor with R410A or R32 refrigerant, it delivers the right balance of capacity, efficiency, and acoustics — the kind of unit you install once and forget about for a decade. Gold-plated FIN anti-corrosion treatment on the heat exchanger means it thrives where cheaper units corrode: seaside resorts, monsoon-region apartments, and humid urban centers.

Guest Comfort, Simplified

◆ Sleep Mode for Hospitality: The auto-adjusting temperature profile is designed for guest rooms — cooler at bedtime, gradually warming toward morning. Guests wake comfortable, not shivering. No front-desk calls about AC settings at 2 AM.

◆ 4 Fan Speeds with 4D Deflection: More speeds mean finer control over airflow distribution. The 4D system pushes air in four directions simultaneously, eliminating the hot corner problem in L-shaped rooms and open-plan layouts.

◆ 40 dB(A) for Shared Spaces: In a co-working office or hotel suite, an AC shouldn't compete with conversation. At 40 dB, it operates below the typical ambient noise of a quiet office (45-50 dB), making it functionally silent in context.

◆ Programmable 24-Hour Timer: Set once, forget daily. For hotel housekeeping, program the AC to energy-save mode during vacant hours and resume comfort settings 30 minutes before guest check-in.

◆ 6-in-1 Mode Suite: Cooling, Heating, Dry, Dehumidifying, Auto, and Fan — one remote covers every weather scenario. Dry mode is particularly valued in monsoon-region installations where humidity control matters as much as temperature.

◆ 3-Second Rapid Heating: Instant warm air for seasonal locations where mornings dip below comfort range. No pre-heating delay, no guest complaints about cold starts.

Engineering That Scales

◆ LG T1 Rotary Compressor: The same compressor family used in our 24,000 BTU flagship, scaled for 12K BTU output. T1 certification guarantees performance at sustained 52°C ambient — not peak survivability, continuous rated output.

◆ Gold-Plated FIN Anti-Corrosion: A microscopic gold-alloy layer electroplated onto the aluminum heat exchanger fins. Independent testing shows 3× longer corrosion resistance versus uncoated fins in salt-spray chamber tests (ASTM B117 equivalent). Maintains heating output at -25°C.

◆ R410A / R32 Dual Compatibility: Factory-configured for either refrigerant. R32 offers 68% lower GWP (675 vs 2088) for markets with carbon-conscious procurement policies.

◆ ISO 9001 Manufacturing: Every KF-12GW undergoes a full 45-minute factory run-test across all modes before packaging. Defect escape rate is below 0.3% across our production line — verified by third-party quality audits.

◆ CE & RoHS Compliance: All materials — from the refrigerant circuit to the ABS front panel — meet European safety and environmental standards. Full documentation available for customs clearance and regulatory filing.

Deployment Scenarios

◆ Hospitality: 30-room boutique hotel in a coastal city. Installer runs 2.6M pre-flared pipe from outdoor ledge to each room. Housekeeping cleans reusable filters between guest stays — under 60 seconds per unit.

◆ Residential: Family of four in a 120㎡ apartment. One KF-12GW in the 30㎡ living-dining area, complemented by KF-9GW units in bedrooms. Unified remote control protocol — same remote works across models.

◆ Co-Working Spaces: 200㎡ open floor with 6 KF-12GW units zoned by area. ECO mode reduces total electrical load during low-occupancy afternoons. Timer programming aligns cooling schedules with booking system.

◆ Institutional: School computer lab with 35 students generating 3.5kW of body heat plus equipment load. Two KF-12GW units maintain 24°C at 50% RH — verified by facility manager after one full academic year.
