When 100㎡ Needs Cooling — Without the 20,000 BTU Price Tag

A 100㎡ factory floor, event hall, or open-plan commercial space represents a serious cooling challenge. The HVAC answer — ducted systems or multiple split AC units — comes with six-figure installation costs and monthly bills that rival rent. The DeTong TM-1304Y 70L industrial evaporative air cooler takes a different path: 180 watts. Less power than two incandescent bulbs, driving a 4-sided thickened wet curtain system that cools up to 100㎡ through natural evaporation. With a 70L (19-gallon) dual-tank configuration, it runs continuously for up to 80 hours — from Monday morning to Thursday afternoon on one fill. At 1.3 meters tall, airflow delivers at optimal standing height for commercial environments.

The Physics of 80-Hour Cooling

The TM-1304Y's dual-tank system is engineered for maximum runtime: a 35L upper gravity-feed tank saturates the 4-sided wet curtain, while a 35L lower collection tank captures runoff and feeds the recirculation pump. This closed-loop design means every drop of water passes through the evaporative curtain multiple times before being exhausted as humidity. At 180W pump and fan power, water-to-air heat exchange efficiency is approximately 85% — meaning 85% of thermal energy removed from the airstream is absorbed by water evaporation rather than electrical work. Compare to compressor AC, where every watt of cooling requires approximately 0.3-0.4 watts of electrical input. The TM-1304Y achieves effective cooling at a fraction of the electrical cost per square meter.

Intelligent Control for Large-Space Management

◆ Remote Control with Full Function Access: Adjust fan speed, toggle oscillation, activate cooling mode, and set timer — all from up to 6 meters away. In a 100㎡ space, the unit may be positioned 15 meters from the operator's workstation.

◆ 3-Speed Fan with Cold Air Boost: Speed 1 for maintenance airflow during off-peak. Speed 2 for standard occupancy. Speed 3 for peak heat — afternoon sun on a west-facing bay, 100-person event at capacity. Cold Air button increases pump flow for maximum evaporative output on demand.

◆ Blade-Free Safety Oscillation: Same proven safety design — no exposed spinning blades. Internal fan draws air through wet curtain, expels through protected grille. Automatic oscillation covers full floor width. Meets safety requirements of public-access commercial spaces.

◆ 70L Dual-Tank Monitoring: Front panel water level indicator shows remaining capacity in both tanks. Anti-dry-burn pump cut-off protects the motor. Refill takes 20 seconds through the top-loading cover.

Engineered for These Environments

◆ Factories & Assembly Floors: 100㎡ production area with machinery heat load and 20 workers. Spot cooling at the assembly line without the impossible task of air-conditioning an entire open factory. 180W per unit — deploy 10 units across 1,000㎡ on a single 20A circuit.

◆ Event Halls & Banquet Spaces: Weekend wedding venues, community halls, conference centers. Portable deployment — roll units in for the event, out afterward. No permanent mounting, no structural modifications to heritage or rented buildings.

◆ Commercial Greenhouses & Nurseries: Evaporative cooling is ideal for plant environments — added humidity benefits foliage health while temperature reduction prevents heat stress. 80-hour runtime aligns with weekend watering schedules.

◆ Logistics & Loading Docks: Semi-enclosed bays where truck exhaust and open doors make compressor AC impractical. Positive-pressure airflow helps push contaminated air outward while cooling the dock workers' zone.
