The Chiller That Turns Waste Heat Into Revenue
Large commercial properties face a paradox: they pay for cooling year-round, yet during cooler months, they vent usable heat into the atmosphere. The AirBoost air-cooled screw chiller with triple free cooling flips this equation. Air-side free cooling eliminates compressor operation during cool weather. Water-side free cooling provides efficient partial cooling in shoulder seasons. And the desuperheater heat recovery system captures waste heat to produce domestic hot water—whenever the chiller runs.
For the investor, this means a single piece of equipment that generates three revenue streams: cooling efficiency, heating offset, and reduced utility costs. When a hotel, hospital, or mixed-use development can produce free hot water every time the chiller operates, the ROI calculation changes fundamentally. The AirBoost isn't just a chiller—it's a combined heating and cooling plant that pays for itself faster than any conventional alternative.
Key Features Deep Dive
1. Triple Free Cooling – Three Efficiency Gains in One Machine
The AirBoost's defining advantage is its triple free cooling capability, each mode converting wasted energy into measurable savings:
  • Air-side free cooling: When ambient temperature drops below the chilled water setpoint, the system uses outdoor air directly for cooling through a dedicated coil. The compressor slows to minimum speed or stops entirely. In temperate climates, this mode can provide 100% of cooling needs for 3-5 months per year—at a fraction of the energy cost.
  • Water-side free cooling: During shoulder seasons, the system provides elevated-temperature cooling (12°C supply instead of 7°C) using ambient air, with the compressor running at minimum speed. This delivers 20-30% of full-load power consumption while meeting the cooling needs of fan coil systems.
  • Desuperheater heat recovery: Hot discharge gas passes through a dedicated heat exchanger before entering the condenser, transferring heat to a domestic hot water circuit. This provides free hot water whenever the chiller is running—a direct offset to boiler fuel costs.
What this means for your investment:
  • 3-5 months of near-free cooling—In temperate climates, compressor barely runs
  • 20-30% power consumption—Shoulder season water-side free cooling
  • Free domestic hot water—Desuperheater offsets boiler fuel 12 months a year
  • Annual energy reduction of 30-50%—Combined effect across all three modes
  • Smaller boiler plant needed—Heat recovery offsets peak hot water demand
  • Faster payback—Premium equipment cost recovered in 2-3 years vs. standard chiller
2. Variable-Speed Screw Compression – Efficiency Where It Counts
The AirBoost uses variable-speed drive on its twin screw compressors, delivering continuous capacity modulation from minimum to maximum. Unlike fixed-speed screw chillers that waste energy through hot gas bypass at part load, the VSD adjusts motor speed to match actual demand. At typical commercial part-load conditions (50-70% capacity), the VSD screw compressor consumes 25-35% less energy than a fixed-speed equivalent.
What this means for your investment:
  • Continuous stepless modulation—No inefficient step-loading or hot gas bypass
  • 25-35% part-load savings—vs. fixed-speed screw compressors
  • COP 3.45 at full load—Strong baseline efficiency
  • IPLV 4.7—Excellent integrated annual performance
  • Soft starting—Reduced inrush current, smaller electrical infrastructure
  • Lower vibration—Extends equipment life and reduces maintenance
3. Heat Recovery Transforms the Economics
For hotels, hospitals, and mixed-use developments with simultaneous heating and cooling demands, the desuperheater heat recovery fundamentally changes the economic equation. Consider a 500-room hotel: conventional systems pay for chiller cooling and boiler heating separately. With the AirBoost's heat recovery, every kilowatt of cooling simultaneously generates hot water for guest rooms, laundry, and kitchens. The effective cooling cost drops dramatically because the "waste" heat becomes a revenue-generating product.
What this means for your investment:
  • Simultaneous heating and cooling—One machine does the work of two
  • Hot water at near-zero marginal cost—While cooling, hot water is free
  • Reduced boiler capacity—Smaller boiler plant = lower capital cost
  • Lower gas consumption—Reduce fossil fuel dependency and carbon emissions
  • Hotel ROI acceleration—Payback on HVAC investment 30-40% faster
  • Hospital operational savings—Sterilization and domestic hot water offset
4. T3 55 °C – Certified for the Hottest Markets
For investors developing in the Middle East, South Asia, Southeast Asia, or Africa, T3 certification is non-negotiable. The AirBoost delivers full rated capacity at 55°C ambient temperature. Many competing products are rated only for T1 (35°C) or T2 (40°C), requiring 20-40% oversizing to deliver rated capacity in hot climates—at proportionally higher cost. The AirBoost's T3 certification means nameplate capacity equals delivered capacity, eliminating the oversizing penalty.
What this means for your investment:
  • Full capacity at 55 °C—No oversizing required
  • Lower equipment count—Fewer units needed vs. T1/T2-rated chillers
  • Reduced capital cost—No oversizing premium
  • Proven in extreme climates—Thousands of units in Middle East and Africa
  • Accurate capacity planning—Nameplate = delivered
  • Faster project payback—Capital deployed efficiently from day one
5. R134a/R513A – Global Compliance and Serviceability
The AirBoost offers R134a and low-GWP R513A refrigerant options. R134a is the most widely used HFC in large screw chillers globally—available in every market, serviceable by every technician. R513A (GWP 631, a 56% reduction) provides a drop-in replacement for projects targeting F-Gas compliance and ESG goals. Both are non-flammable (A1 safety class), eliminating the need for special safety measures.
What this means for your investment:
  • R134a: Global availability—Service anywhere in the world
  • R513A: Low-GWP compliance—56% lower GWP, drop-in compatible
  • Non-flammable—No special safety infrastructure needed
  • Established service network—Every HVAC technician can service
  • Future-proof—Compliant with current and near-future F-Gas regulations
  • ESG reporting support—Lower-GWP option supports sustainability targets
6. Built for 20+ Years of Revenue Generation
The semi-hermetic twin screw compressors are field-serviceable—bearings, seals, and valves can be replaced without removing the compressor from the unit. The microchannel condenser is corrosion-resistant with a 20+ year design life. The heavy-duty steel frame is engineered for decades of outdoor exposure. This is an asset designed to generate rental income and tenant comfort for the full duration of your investment hold period.
What this means for your investment:
  • Semi-hermetic serviceability—Field repair without full compressor replacement
  • 20+ year design life—Matches typical commercial property hold periods
  • Corrosion-resistant condenser—Long-term reliability in all climates
  • Heavy-duty frame—Engineered for outdoor exposure
  • Spare parts availability—20+ year commitment
  • Predictable depreciation—Matches financial modeling assumptions
