What makes a Gradian Scroll Chiller?
Precise Load Matching
Digital scroll technology closely tracks real-time cooling demand, reducing unnecessary energy consumption at partial load.
Modular Parallel Staging
Multiple units install in parallel to increase total system capacity, supporting redundancy and improved part-load performance without oversizing a single unit.
High-Efficiency Heat Rejection
Microchannel condenser coils paired with EC variable-speed fans optimize airflow while reducing fan energy consumption and sound levels.

Add Capacity Without Overbuilding
Needing another 40 tons of cooling shouldn’t force your facility into an oversized central-plant investment. Add right-sized chilled-water capacity for a new IT room, support space, production process, or incremental facility load.
40-Ton Modular Capacity - Add cooling in manageable increments.
Parallel Installation - Combine units as total demand grows.
Application Flexibility - Support supplemental and phased cooling requirements.
Service One Module Without Losing Cooling
Modular staging means individual units can be serviced without interrupting total cooling capacity—supporting the uptime mission-critical environments depend on.
Individual Module Servicing - Take one unit offline for maintenance while others continue operating.
System or Unit-Level Redundancy - Distribute cooling load across multiple units instead of a single point of failure.
Continuous IT Cooling - Maintain critical cooling capacity during scheduled maintenance.
Future-Proof Your Cooling Investment
Using low-GWP A2L refrigerant, Gradian’s modular scroll chiller supports ever-evolving environmental requirements without sacrificing efficient heat transfer or capacity control.
Low-GWP A2L Refrigerant - Reduce environmental impact compared to traditional HFC refrigerants.
Next-Gen Compliance Ready - Align with evolving refrigerant regulations before they take effect.
No Performance Trade-Off - Maintain efficient heat transfer and capacity control with the lower-GWP formulation.
Questions, answered.
An air-cooled modular chiller is a self-contained cooling unit that rejects heat directly to outside air and can be installed in parallel with additional units to increase total system capacity. This model delivers 40 tons of cooling capacity per unit and supports staged, redundant deployment.
