Screw Chiller COP 5.0 5.9

Product Description
Water Cooled Screw Chiller 570-2070 kW
COP 5.0-5.9 Consistent Efficiency | R134a R22 R407C | T3 55°C
The Efficiency Baseline That Doesn't Move
Energy benchmarking across a chiller portfolio is only meaningful when performance data is consistent and weather-independent. The water-cooled screw chiller delivers COP values of 5.0-5.9 that remain stable regardless of outdoor ambient temperature because the cooling tower buffers the condenser water at a consistent 30-35°C.
Unlike air-cooled systems that derate in hot weather, the water-cooled screw provides the same efficiency data point in January and July, in London and Dubai. For the energy manager building accurate carbon models and energy benchmarks, this consistency is invaluable.
At COP 5.5, every 1 kW of electrical input produces 5.5 kW of cooling. For a 1,500 kW system running 5,000 hours annually at 60% average load, annual electricity consumption is approximately 1,364,000 kWh compared to approximately 2,143,000 kWh for an equivalent air-cooled system at COP 3.5. That is a 779,000 kWh annual reduction equivalent to 312 tonnes of CO₂ avoided at the global average grid emission factor.
Key Features Deep Dive
COP 5.0-5.9 – Highest Efficiency at This Capacity
Water-cooled systems achieve fundamentally higher COP than air-cooled alternatives because the heat rejection temperature (30-35°C from the cooling tower) is significantly lower than peak ambient air temperature (40-55°C in hot climates). The water-cooled screw chiller achieves COP values of 5.0 to 5.9 – the highest available for this capacity range.
What this means for your energy program:
  • COP 5.0-5.9 – Best-in-class efficiency for 570-2,070 kW range
  • Lowest Scope 2 per ton of cooling – Minimum electricity per unit output
  • Annual savings of 779,000 kWh – At 1,500 kW scale vs. air-cooled equivalent
  • 312 tonnes CO₂ avoided annually – At global average grid emission factor
  • Favorable energy benchmarking – Outperforms air-cooled alternatives
  • Carbon reduction ROI – Energy savings justify investment in water infrastructure
Weather-Independent Efficiency – Reliable Carbon Modeling
The cooling tower maintains condenser water at a consistent 30-35°C regardless of outdoor temperature. This means the chiller's COP remains stable across all operating conditions – a critical advantage for energy managers building annual carbon models.
What this means for your energy program:
  • Stable COP year-round – No weather-dependent efficiency variation
  • Accurate annual carbon models – No seasonal adjustment factors needed
  • No heat-event energy spikes – Efficiency maintained at peak demand
  • Reliable benchmarking – Consistent data across climate zones
  • Predictable utility costs – No summer energy cost surprises
  • ESG data integrity – Actual consumption matches projected consumption
Dual Circuit Redundancy with No Efficiency Compromise
The semi-hermetic twin screw compressors operate on independent circuits. At normal part-load conditions, one circuit runs at peak efficiency. The second circuit activates only when needed. Both circuits can share load at moderate part-load, with each operating in its most efficient range.
What this means for your energy program:
  • One circuit at peak efficiency at part load – Optimal single-circuit operation
  • No redundancy energy penalty – Backup available without waste
  • Dual circuit shared load – Both in efficient range at moderate demand
  • Maintenance without efficiency loss – One circuit serviced while other runs
  • Consistent efficiency data – Predictable regardless of circuit configuration
  • Lower lifecycle emissions – No wasted energy during normal redundant operation
25%-100% Stepless Modulation – Match Load Precisely
The capacity modulation range of 25% to 100% ensures the chiller precisely matches actual load at all times. Unlike systems with step-loading, continuous modulation eliminates the energy waste of over-cooling during low-demand periods.
What this means for your energy program:
  • 25%-100% continuous modulation – Precise load matching at all times
  • No over-cooling waste – Eliminates energy wasted during low-demand periods
  • High efficiency across range – Not just at full load
  • Smooth capacity response – No step-loading temperature swings
  • Accurate consumption data – Linear relationship between load and energy
  • Lower annual consumption – No wasted cooling energy
Multiple Refrigerant Options for Compliance Flexibility
The water-cooled screw supports R134a (GWP 1,430), R407C (GWP 1,774, transitional), and R22 (for existing infrastructure markets). For new projects targeting low environmental impact, R134a provides the best balance of efficiency and GWP.
What this means for your energy program:
  • R134a: Best balance – Good efficiency with moderate GWP
  • R513A: Low-GWP option – 56% lower GWP, drop-in compatible
  • R407C: Transitional – For markets transitioning from R22
  • R22: Existing infrastructure – Where service network supports it
  • Per-project optimization – Match refrigerant to local regulations and targets
  • Migration path available – Upgrade options as regulations evolve
Scalable for District Energy with Centralized Monitoring
For energy managers overseeing district cooling networks, the water-cooled screw chiller is designed for parallel installation on common headers. Two, three, or four units combine to serve loads from 1,000 kW to over 8,000 kW.
What this means for your energy program:
  • Parallel installation – 2-4 units for centralized district plants
  • Aggregated energy data – District-level consumption visibility
  • Fleet benchmarking – Compare individual units against fleet averages
  • Centralized optimization – Stage units for maximum system efficiency
  • District carbon reporting – Single data source for the entire plant
  • Scalable monitoring – Add units without redesigning data architecture
