Efficient, Simple and Reliable

The YORK® YVFA Free-cooling VSD Screw Chiller
The YORK® legacy of innovation continues with YORK YVFA Free-Cooling Chillers, delivering the lowest possible yearly energy consumption and life-cycle costs with payback in less than two years by combining superior engineering and technology in a packaged design that’s simple to own and operate. 

The chiller's advanced technologies include Johnson Controls expertise in variable-speed driven (VSD) compressors that ensure efficient operation across all cooling-load and ambient temperature conditions. The integrated high-efficiency air-to-liquid free cooling coils, designed by Johnson Controls heat transfer experts, reduce or eliminate the need for mechanical cooling when ambient conditions allow. Intelligent controls optimize energy use year-round, constantly evaluating conditions and controlling bypass valves to reduce pump energy when free cooling is not available.  

Operating cost payback in as little 2 years – and we can prove it.

Our Annual Energy Cost (AEC) tool illustrates how most facilities operating 24/7 with a constant cooling load can achieve an operating cost payback in as little as two years. The AEC tool accounts for geographic location, building type, operating hours, utility costs and local weather to provide the most accurate data possible in a simple format.

See how efficient YORK® YVFA free-cooling chillers use less kW/ton during most annual operating hours when compared to traditional chillers with the AEC tool. 

Saving energy is simple. In every situation.

The advanced technology in YVFA free-cooling chillers enable operation in three modes (mechanical, hybrid and free) to best align with current ambient conditions, boosting efficiency. Single point controls simplify operation to easily accommodate process or building changes. Set point changes are easily made through the control panel or Building Automation System (BAS). The free-cooling controls automatically adjust to deliver the best performance at required conditions.

Hybrid cooling mode provides an efficiency advantage!

For unsurpassed efficiency at part-load, intelligent controls optimize the balance between using fans to move air over the free cooling coils with the outstanding efficiency of the VSD compressor.  

Why install anything but YORK®?

Rely on Johnson Controls for your critical process operation.  With three generations of expertise in VSD technology, including the 2005 EPA Climate Protection Award,  you will receive peace of mind from superior efficiency and reliability.

Zero-inrush soft start and a high power factor across the entire operating range – both enabled by variable-frequency drive compressor technology.

Quick start option achieves full load after a power-loss in four minutes or less – providing assured cooling for critical process and data center applications.

A liquid-cooled VSD keeps the electrical panel free of dust and dirt, and operating across a wide ambient temperature range.
