Why Choose This Model
Product Highlights
Two-Stage Indirect-Direct Cooling
Indirect stage pre-cools intake air without adding moisture, then direct stage brings supply air to 14-16°C—10°C lower than single-stage evaporative coolers
120% Wet-Bulb Efficiency
Surpasses the 100% wet-bulb limit of standard evaporative coolers—pre-cooled intake air lets the direct stage deliver colder supply air than single-stage designs can achieve
85% Power Cut vs DX
4.2kW total power delivers 12.5TR (44kW) of cooling—replacing traditional DX systems that would draw 28kW+ for equivalent capacity
70% Less Humidity Increase
Indirect-first architecture means most cooling happens without adding moisture to supply air—ideal for dry-climate industrial spaces and electronics manufacturing
IP54 Industrial Enclosure
Dust-protected and splash-resistant electrical cabinet for harsh industrial environments—paired with a 0.72 power factor and 8.5A total current on 400V/3/50 power
Core Advantages
14-16°C Supply Air, Even at 45°C Ambient
The two-stage IDEC architecture pre-cools intake air through a heat exchanger (zero moisture added), then the direct evaporative stage achieves final cooling. Supply air temperature stays steady at 14-16°C, with up to 18°C total temperature drop — approaching air-conditioner comfort without the compressor.
4.2kW Replaces 28kW+ DX Systems
Centrifugal primary blower (2.6kW) plus secondary axial fan (0.85kW) deliver 44kW of cooling from just 4.2kW total input. Cuts electricity consumption by 80-85% versus equivalent packaged DX air conditioners. Precision thermostat control with inverter variable-speed drive keeps energy use exactly where needed. Carbon emissions reduced by up to 85%.
No Recirculation, No CO₂ Buildup
Unlike conventional packaged AC systems that recirculate indoor air, the IDEC9000 draws 100% fresh outdoor air and exhausts directly to the outside. Continuous air replacement eliminates indoor CO₂ accumulation and stale air. Compressor-free construction removes the highest-cost failure point in traditional HVAC under high-temperature conditions.
IP54, Washable Filter, Automatic Drain
IP54-rated electrical enclosure withstands dust and water spray. Reusable washable air filter and programmable automatic drain system keep routine maintenance to a minimum. Two independent water tanks (indirect 0.15m³ + direct 0.063m³) with DN15 inlet and DN25 drain. Precision thermostat control with inverter drive maximizes runtime efficiency.
