Air Cooled Screw Chiller Midea AirBoost Variable-Speed 400-1,450 kW AHRI 551 591 T3-Rated Air-Cooled Screw Chiller for Extreme Climates -25 °C to 52 °C Operation

High-capacity 400-1,450 kW AHRI 551/591 T3-Rated chiller designed for extreme climate operation from -25°C to 52°C, delivering mission-critical cooling without water-cooled infrastructure costs.

The Midea AirBoost Air Cooled Screw Chiller serves demanding applications where operational reliability outweighs equipment cost. With capacities reaching 1,449 kW on R134a and 1,335 kW on R513A, this platform eliminates the need for traditional water-cooled plant infrastructure.

• Variable-Frequency Screw, 0.1 Hz Precision – Real-time motor-speed matching eliminates part-load waste; IPLV 5.0+ delivers 30-40% lower annual energy consumption
• 60-Second Rapid Recovery – Restores full setpoint within 60 seconds after power interruption, protecting process continuity
• Triple Free-Cooling Architecture – Direct, indirect, and mixed modes maximize compressor-free operation; 2,000-4,000 free-cooling hours annually
• R513A Low-GWP Option – Meets F-Gas Phase-Down requirements for EU and forward-looking markets
• -25°C to 52°C, 60 Hz, T3 Certified – Broadest operating envelope in air-cooled screw category
• Noise-Reduction Package (5-10 dBA) – Optional acoustic enclosure enables installation near residential zones
• 8-Unit Parallel Operation – Supports plant capacities up to 11,600 kW from single control platform

Variable-frequency operation maintains IPLV above 5.0 at typical 30-80% load profiles. Free-cooling integration reduces chiller-plant energy by 35-50%, lowering PUE by 0.05-0.12 with 2.5-3.5 year payback.

0.1 Hz inverter precision maintains water temperature within ±0.2°C, protecting product quality. 60-second recovery prevents production-line shutdowns with 25-35% energy savings and 3-4 year payback.

8-unit parallel architecture with staging logic ensures optimal efficiency. Free-cooling hours offset peak-season electricity purchases with 3-4 year payback through tariff optimization.

Wide operating envelope eliminates need for separate winter cooling units. Noise-reduction package avoids expensive acoustic treatment with 65-70% energy savings during free-cooling months.
