Air Cooled Scroll Chiller 320-920 kW
IDV Variable Capacity Plug and Play R410A Energy Saving Up to 40%
The Mid-Market Workhorse That Maximizes Development Yield. Designed for projects in the 300-900 kW cooling range where capital budgets are tight and timelines are aggressive. This air-cooled scroll chiller delivers full capacity in a single factory-tested package - arrive, connect, run. With IDV variable capacity technology delivering up to 40% energy savings, it keeps operating costs low while maintaining reliable tenant comfort.
Key Features Deep Dive
IDV Variable Capacity – Lower Energy Bills Mean Better Tenant Retention
The IDV (Independent Double Variable) system provides continuous, stepless capacity modulation from 12.5% to 100%. Unlike conventional chillers that cycle on and off, the IDV system matches output to actual demand at every moment.
- 12.5%-100% stepless modulation – No energy wasted on on/off cycling
- IEER 4.7-4.8 – Industry-leading part-load efficiency
- Up to 40% energy savings – vs. fixed-capacity systems
- Lower tenant operating costs – Supports lease negotiations and renewals
- Higher NOI – Lower utility costs boost net operating income
- Green building credit – Contributes to LEED, BREEAM, Green Star certification
Single-Package Simplicity – Faster Revenue Generation
Arrives as a single, factory-assembled, factory-tested unit. All components are pre-installed and verified for quick commissioning.
- Factory-tested complete unit – No field assembly of refrigerant piping
- Fast commissioning – Days, not weeks
- Single crane lift – Minimal installation equipment and labor
- Predictable installation cost – No surprise site work or change orders
- Reduced contractor risk – Less complexity means fewer delays
- Earlier certificate of occupancy – Revenue stream starts faster
Dual Independent Circuits for Redundancy
Features dual independent refrigerant circuits providing operational security and continuous operation during maintenance.
- Dual independent circuits – Each with its own compressor and refrigerant
- 50% backup on circuit failure – Tenants keep running during maintenance
- No dedicated backup chiller needed – Save capital and floor space
- Reduced business interruption risk – Continuous operation protects income
- Maintenance scheduling flexibility – Service during off-peak without shutdown
- Higher asset valuation – Redundancy is valued by institutional buyers
No Cooling Tower, No Water Liability
Eliminates water treatment costs, Legionella testing obligations, water consumption charges, and environmental liability.
- Zero water consumption for cooling – Critical in water-stressed regions
- No Legionella risk – Eliminates testing, treatment, and liability costs
- No cooling tower maintenance – Reduce annual OPEX
- Simplified ESG reporting – Water footprint reduction is immediate
- No water discharge permits – Faster regulatory approval
- Lower insurance premiums – Reduced liability exposure
Compact Footprint – Maximize Rentable Area
Smaller rooftop footprint compared to equivalent-capacity water-cooled systems, freeing up space for revenue-generating uses.
- Smaller rooftop footprint – More space for revenue-generating uses
- No cooling tower space – Additional rooftop area freed
- Lighter structural load – May reduce structural steel requirements
- Flexible placement – Ground level, rooftop, or intermediate platform
- Multiple unit arrangement – Side-by-side or distributed configurations
- Compatible with rooftop solar – Free up space for PV panel installation
Proven Technology – 20+ Year Track Record
Scroll compressor technology is among the most mature and reliable in the HVAC industry with decades of field validation.
- Decades of field validation – Millions of units operating worldwide
- Readily available spare parts – Short lead times, competitive pricing
- Large service technician pool – No dependency on specialized contractors
- Predictable maintenance costs – Well-understood service intervals
- Lower technology risk – Proven, mature, reliable
- Resale value – Recognized and trusted by secondary market buyers
