    Features

    • Packaged controls for single-point convenience to easily accommodate process or building changes
    • ISASecure® certified YORK® Chiller Access Manager with enhanced security features provides peace of mind that chiller data and operations are secure
    • Variable-frequency inverter technology enables a zero-inrush soft start and a high-displacement power factor across the entire operating range
    • Performance is assured by AHRI certification, the first for an air-cooled screw chiller with free-cooling
    • Open-loop and closed-loop design solutions for different building systems
    • Advanced touchscreen display provides faster, easier navigation compared to legacy 2-line displays
    • Intelligent controls also optimize the balance between using fans to move air over the free-cooling coils
    • Quick Start option achieves full load after a power loss in four minutes or less
    • Integrated air-to-liquid, free-cooling coils, designed by our heat transfer experts, reduce or eliminate the need for mechanical cooling when conditions allow

    Quick Start

    After power is interrupted, it can take a standard chiller up to 10 minutes to restart. But with the Quick Start feature, YVFA chillers can restart within seconds after power is restored. YVFA chillers feature an industry-leading compressor restart (upon power being restored) of 34 seconds.

    Because YVFA chillers contain a variable-speed drive, there is no inrush of current. As a result, all compressors can be started together. This allows a faster ramp-up to full capacity than possible with a typical chiller.

    Hybrid Mode Technology

    Traditional free-cooling chillers use fixed-speed compressors that simply shut off when ambient temperatures are low enough. But this only saves energy when the compressors are completely shut off. Johnson Controls has pioneered a unique Hybrid Mode technology that optimizes energy use year-round. Using free-cooling coils to reduce the mechanical cooling load at a much higher temperature, the VSD compressors reduce speed and energy use more of the year for long-term performance and efficiency.

    Free-cooling Technology

    YVFA free-cooling, air-cooled chillers deliver the industry’s highest leaving water temperature to provide more tonnage in the same footprint as competing systems. And intelligently controlled free-cooling bypass valves reduce pump energy when free-cooling is not beneficial. These technologies enable the chiller to move from mechanical to hybrid to free-cooling modes automatically, further minimizing energy use.
    YORK YVFA Variable Speed Screw Chiller is equipped with free-cooling technology, minimizing energy use and maximizing efficiency.

    CHILLER SECURITY

    The YORK® YVFA Air-cooled Chiller has received ISASecure® CSA certification through Exida®, meeting rigorous international standards for cybersecurity in industrial automation and control systems. This certification demonstrates our commitment to helping facility teams safeguard critical infrastructure against evolving threats.
    • Certification to the ISA/IEC 62443-4-2 standard provides assurance that Johnson Controls and the YORK® brand adhere to stringent ISASecure technical security requirements for IACS components.

    • Certification to the ISA/IEC 62443-4-1 standard provides assurance that Johnson Controls and the YORK® brand adhere to stringent ISASecure development lifecycle requirements.

    The YORK® YVFA Air-cooled Chiller is one of many chiller models from Johnson Controls equipped with the Chiller Access Manager to receive ISASecure certification from Exida®.The YORK® Chiller Access Manager provides YORK® YVFA Air-cooled Chiller owners and operators with control and visibility about who is operating, maintaining and servicing their chiller – ensuring protection of an asset that is critical to facility operation.
