Surpassing Efficiency Standards with High Performance
The YORK® YMAA and YMPA Series Air-Cooled DC Inverter Scroll Chiller and Heat Pump are engineered to meet future efficiency standards ahead of time.
The YORK® YMAA and YMPA Series exceed typical efficiency levels for chillers and heat pumps, meeting or surpassing strict regulatory requirements with YORK® efficiency technologies.
Performance Without Compromise
Designed to excel in a broader range of operating conditions, the YMAA and YMPA chiller and heat pump maintain efficiency without requiring kits or add-ons, even at challenging temperatures as low as -18°C in cooling mode and -15°C in heating mode.
With a compact footprint and a broad capacity range, the YORK® YMAA and YMPA Series provide efficient performance in smaller spaces.
Our systems offer two sound performance levels. For even quieter operation, you can opt for the Ultra Quiet Kit, which reduces sound power by an impressive 6 dBA, making it one of the quietest units available.
Advanced Control Made Easy
YORK® YMAA and YMPA Series with advanced, embedded control capability allows multiple chillers and/or heat pumps to be connected and monitored through a single controller.
Each unit comes equipped with a touch-screen display featuring an easy-to-use, web-style interface and intuitive navigation for easy access to operational data.
YORK® YMAA and YMPA Series provides added flexibility with standard BACnet MS/TP and Modbus RTU connectivity for communication with virtually any building management system.
A History of Reliability
Our initial modular chiller was constructed more than a decade ago, and it incorporates DC inverter technology with a track record spanning over three decades.
Every new YORK® chiller undergoes a Highly Accelerated Life Test (HALT) during product development, simulating extreme conditions to ensure long-term reliability and quality.
Features
DC inverter technology enhances YMAA and YMPA Series chiller efficiency across varying conditions, unlike less flexible constant speed chillers.
EC fans, using efficient motors and improved aerodynamics, enhance system efficiency and sound performance, especially at partial loads.
As temperatures decrease, head pressure control varies fan speeds for efficiency and reliability. This dual-variable method, adjusting both compressor and fan speeds, achieves a high displacement power factor of up to 0.93, cutting electricity expenses.
The high-efficiency brazed plate heat exchanger uses less refrigerant and efficiently transfers heat from liquid to refrigerant, ensuring exceptional performance in a compact form. It also reduces water side pressure drop, enabling the use of smaller pumps and minimizing building power usage.
The tandem compressor design employs multiple circuits to enhance efficiency during off-design and part-load conditions by utilizing the entire heat exchanger surface area. Additionally, it offers partial redundancy for increased reliability.
