Open Loop Chiller System Models

High-Performance Open Loop Chiller Systems for Reliable Cooling

Engineered for Precision Cooling in Demanding Applications

Filtrine’s open loop chillers are custom-built to meet the needs of mission-critical operations where precision temperature control is essential. These systems are ideal for applications ranging from medical imaging equipment and laboratory processes to manufacturing lines and food production.

Our open loop chiller design uses an external water supply—typically from a plant loop, tower, or city water source—to cool the chiller’s internal heat exchanger. This configuration eliminates the need for an internal condenser water circuit, simplifying maintenance and reducing operating costs.

Benefits of Filtrine Open Loop Chillers

  • Custom-built for your specifications: Each unit is engineered for your exact cooling load, ambient conditions, and space constraints.
  • Lower maintenance requirements: Fewer moving parts and simplified water pathways mean fewer service interruptions.
  • Greater energy efficiency: Utilizing an existing water supply reduces compressor load and lowers utility costs.
  • Compact and space-saving designs: Flexible configurations to fit tight mechanical rooms or equipment enclosures.
  • Long product lifecycle: Constructed with non-ferrous materials and robust components for long-term reliability.

Open Loop Chiller FAQs

What is an open loop chiller and how does it work?

An open loop chiller uses an external water source—such as city water, well water, or a cooling tower—to reject heat from the system. This differs from closed loop chillers, which recirculate internal fluid. Open loop chillers are ideal when a reliable external water source is readily available.

What are the advantages of using an open loop chiller system?

Open loop systems offer energy savings, simpler operation, and reduced maintenance. By leveraging an existing water source, these chillers reduce internal system complexity and deliver reliable performance with fewer components to service.

What types of applications benefit most from open loop chillers?

They are ideal for facilities with consistent access to city water or a central plant loop, especially in industries like medical imaging, laboratory research, industrial manufacturing, and food production.

How do open loop chillers compare to closed loop chillers?

While open loop chillers rely on an external water supply, closed loop systems recirculate a self-contained coolant. Open loop systems are typically more efficient when external water is abundant, but may require water treatment to prevent fouling or scale.

Can Filtrine customize an open loop chiller for specific project needs?

Yes. Every Filtrine chiller is engineered to order. We tailor the system’s cooling capacity, footprint, pump specs, controls, and more based on your application requirements.

Are Filtrine open loop chillers compatible with clean room or explosion-proof environments?

Absolutely. Filtrine offers models with clean room-compatible finishes and explosion-proof components certified for hazardous environments. Custom enclosures and NEMA-rated electrical options are available.

What maintenance is required for an open loop chiller?

Because open loop systems use external water, maintenance typically includes monitoring water quality and inspecting heat exchanger surfaces. Filtrine units are designed for easy access and minimal servicing over the life of the system.
