Air Cooled Scroll Chiller 320 920 kW IDV Variable Capacity Zero Water Consumption R410A IEER 4.7 4.8

Commercial chillers operate at peak load for only 1-5% of annual hours, making part-load efficiency the critical metric for annual energy consumption. The IDV system delivers IEER values of 4.7-4.8 – among the highest available for scroll chillers in this capacity range – translating to up to 40% energy savings compared to conventional fixed-capacity models.

• IEER 4.7-4.8 – Industry-leading integrated efficiency
• 12.5%-100% stepless modulation – No cycling waste at any load point
• Up to 40% energy savings – vs. fixed-capacity conventional chillers
• Lower Scope 2 emissions – Reduced electricity consumption means less carbon
• Favorable energy benchmarking – Outperforms most competing products
• ROI from energy savings – Premium typically recovered in 2-4 years

Air-cooled chillers require zero water for heat rejection. A comparable water-cooled chiller consumes approximately 2-4 liters per second of makeup water through evaporative losses, representing 36,000-72,000 cubic meters per cooling season – a significant liability in drought-prone regions.

• Zero cooling tower water consumption – Eliminates 36,000-72,000 m³ per season
• No water treatment chemicals – Eliminates biocide and inhibitor environmental impact
• No Legionella risk – Removes testing, treatment, and liability costs
• No blowdown discharge – Eliminates contaminated water disposal
• Water stress resilience – Operations unaffected by water restrictions
• ESG water disclosure advantage – Dramatically lower water footprint

The RHAE/RCAE series features two independent refrigerant circuits. During normal part-load operation, only one circuit runs at high efficiency, with the second activating only when load increases beyond single-circuit capacity.

• Single-circuit efficiency at part load – One circuit runs at optimum point
• No redundancy energy penalty – Backup capacity available without waste
• Shared load at moderate demand – Both circuits in efficient range
• Graduated capacity response – Smooth ramp-up matches actual demand
• Maintenance without energy loss – One circuit serviced while other runs at full capacity
• Consistent efficiency data – Predictable energy consumption across operating scenarios

The scroll chiller's compact design eliminates not only the cooling tower but all associated water infrastructure: pumps, pipes, treatment systems, blowdown drains, and makeup water connections.

• No cooling tower embodied carbon – Eliminates tower manufacturing emissions
• No water pump energy – Additional electrical savings
• No water treatment chemical supply chain – Reduced Scope 3 emissions
• Simpler environmental management system – Fewer processes to monitor and report
• Reduced maintenance waste – No tower fill replacement, no chemical containers
• Faster environmental certification – Fewer systems to document and verify

Standard Modbus and BACnet connectivity enables direct integration with building energy management systems, providing real-time energy consumption, operating capacity, and efficiency metrics for comprehensive reporting.

• Real-time energy data – Consumption, capacity, and efficiency metrics
• ISO 50001 audit-ready – Verified energy consumption records
• GHG Protocol Scope 2 compliant – Electricity data for carbon calculations
• Portfolio benchmarking – Compare performance across properties
• Performance gap detection – Identify anomalies before they become waste
• Automated reporting – Data feeds directly into ESG and sustainability platforms

Scroll compressor technology maintains consistent efficiency over decades of operation, unlike systems with progressive efficiency degradation from oil fouling, filter clogging, or component wear.

• 20+ year consistent efficiency – No progressive degradation
• Sealed system design – No oil fouling of heat exchangers
• Accurate long-term energy projections – No annual degradation factor
• Predictable lifecycle emissions – Carbon models remain valid
• Lower lifecycle carbon intensity – Efficient operation compounds over decades
• Simplified replacement planning – Known performance at end of life
