Modular Chiller Triple Free Cooling

Product Description
Win More Projects by Offering Lower Operating Costs
As a contractor competing for large commercial projects, the AirBoost air-cooled screw chiller gives you a powerful differentiator: the ability to promise your client dramatically lower operating costs without the complexity of a cooling tower system. The triple free cooling feature — air-side, water-side, and heat recovery — means you can deliver annual energy savings of 30-50% compared to conventional air-cooled chillers. This compelling value proposition helps you win bids and build long-term client relationships.
What makes this even more attractive from a contracting perspective is that you deliver all this efficiency without any cooling tower installation. No water treatment systems, no Legionella compliance programs, no water supply connections. The entire system is air-cooled and rooftop-mounted, which means simpler installation, fewer trades to coordinate, and faster project completion.
Key Features Deep Dive
1. Triple Free Cooling — Your Competitive Advantage in Bids
The AirBoost offers three distinct free cooling modes that work together to minimize your client's energy bill year-round:
  • Air-side free cooling: When outdoor temperature drops below the chilled water setpoint, the system switches to direct outdoor air cooling through a dedicated coil. The compressor stops entirely. In temperate and continental climates, this mode provides 100% of cooling needs for 3-5 months per year at near-zero energy cost.
  • Water-side free cooling: During shoulder seasons, the system provides elevated-temperature cooling (12°C supply) using ambient air with the compressor at minimum speed. This delivers cooling at 20-30% of full-load power consumption.
  • Desuperheater heat recovery: Hot discharge gas transfers heat to a domestic hot water circuit before entering the condenser. Whenever the chiller runs, free hot water is produced — a dual benefit that eliminates or dramatically reduces boiler fuel consumption.
What this means for your project:
  • 30-50% annual energy savings — Compared to conventional air-cooled chillers
  • Three revenue angles in proposals — Free cooling, heat recovery, and efficiency
  • Shorter payback period — Premium investment typically recovered in 2-3 years
  • Smaller boiler plant — Heat recovery offsets boiler capacity requirements
  • Year-round value — Efficiency gains in every season, not just peak cooling
  • Powerful bid differentiator — Win projects by demonstrating lower TCO
2. Variable-Speed Screw Compression — Smooth and Efficient
The AirBoost uses variable-frequency drive on its twin semi-hermetic screw compressors. The VFD provides continuous, stepless capacity modulation from minimum to maximum, with no inefficient hot gas bypass or step-loading. At typical part-load conditions (50-70%), the VSD screw compressor consumes 25-35% less energy than a fixed-speed equivalent. The soft-start capability also eliminates inrush current, allowing smaller electrical infrastructure and reduced utility demand charges.
What this means for your project:
  • Continuous stepless modulation — Smooth capacity matching, no cycling losses
  • 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 — Smaller switchgear, cables, and demand charges
  • Lower vibration — Less structural requirement, longer component life
3. No Cooling Tower — Simpler Project Execution
By choosing the AirBoost air-cooled screw chiller instead of a water-cooled alternative, you eliminate the entire cooling tower system from the project scope. This means no cooling tower procurement, no water treatment system, no Legionella compliance program, no water supply piping, no blowdown drainage, and no cooling tower maintenance contract. For the contractor, this simplifies coordination, reduces the number of subcontractors, and shortens the project schedule.
What this means for your project:
  • No cooling tower procurement — One less major equipment package
  • No water treatment system — Eliminates chemical treatment costs
  • No Legionella compliance — Removes testing, documentation, and liability
  • Fewer subcontractors — No cooling tower specialist needed
  • Shorter project schedule — Eliminate cooling tower installation timeline
  • Simpler commissioning — Fewer systems to test and balance
4. T3 55 °C — One Product for All Your Global Projects
The AirBoost is certified for T3 climate conditions, delivering full rated capacity at 55°C ambient temperature. This means you can specify the same equipment for projects in any climate zone — from northern Europe to the Middle East, Southeast Asia, and Africa — without capacity derating or redesign. One product platform covers your entire international project portfolio.
What this means for your project:
  • Full capacity at 55 °C — No derating, no oversizing
  • One product for all climates — Simplify global procurement
  • No redesign for hot markets — Same equipment works everywhere
  • Accurate proposals — Nameplate capacity equals delivered capacity
  • Fewer change orders — No surprises from underestimated ambient conditions
  • Consistent service support — Same equipment, same parts, worldwide
5. R134a/R513A — Compliant and Serviceable Worldwide
The AirBoost offers R134a and low-GWP R513A refrigerant options. Both are non-flammable (A1 safety class), eliminating the need for special safety infrastructure such as refrigerant leak detection systems or explosion-proof equipment. R134a is the most widely available HFC refrigerant globally, ensuring your client can always find qualified service technicians and replacement parts in any market.
What this means for your project:
  • R134a: Global availability — Service in any country, any market
  • R513A: Low-GWP option — 56% lower GWP, drop-in compatible
  • Non-flammable — No leak detection or explosion-proof requirements
  • Established service network — Every HVAC contractor can service
  • F-Gas regulation compliant — Meets current and near-future requirements
  • No special training needed — Standard HVAC certifications are sufficient
6. Designed for Easy Long-Term Service
The semi-hermetic twin screw compressors are field-serviceable — bearings, seals, valves, and motors can be replaced without removing the compressor from the unit. The microchannel condenser is corrosion-resistant and self-cleaning with rainfall. All service points are accessible from ground level or a single service platform. This design philosophy means your service team can perform all routine and most major maintenance with minimal equipment and minimal disruption to building operations.
What this means for your project:
  • Field-serviceable compressors — Repair without removal
  • Ground-level service access — No scaffolding or special platforms needed
  • Corrosion-resistant condenser — Rainfall self-cleaning reduces maintenance
  • Standard tools — No proprietary tools required for service
  • Minimal building disruption — Most service performed without system shutdown
  • Long service intervals — Fewer scheduled maintenance visits per year
