1.The capacities are gross ratings. For net capacity, deduct air blower motor, MBh = 3.415 x kW. Refer to the appropriate Blower Performance table for the kW of the supply air blower motor.

2.These ratings include the condenser fan motors (total 1 kW) and the compressor motors but not the supply air blower motor.

York WR300, WR240 warranty Cooling Capacities for WR180 Alternate Reheat Mode

WR240, WR300 specifications

The York WR300 and WR240 are advanced water-cooled screw chillers that embody innovation, efficiency, and sustainability. These chillers are part of York’s renowned product line and are designed for a variety of commercial applications, ranging from large office buildings to industrial processes.

One of the standout features of the WR300 and WR240 models is their energy efficiency. Both units utilize the latest in variable-speed drive technology, which allows for precise control of the compressor speed based on the cooling demand. This results in lower energy consumption, especially in part-load conditions, making the chillers not only eco-friendly but also cost-effective over their lifespan.

The WR300 is designed to provide cooling capacities of up to 300 tons, while the WR240 offers capacities of up to 240 tons. These substantial capacities make them suitable for larger applications where dependable cooling is essential. The units are compact in design, allowing for flexible installation options, even in properties with space constraints.

Another key characteristic of the York WR chillers is their advanced refrigerant technology. Utilizing R-134a refrigerant, these chillers comply with global environmental standards and regulations, contributing to reduced greenhouse gas emissions. This makes the WR300 and WR240 not only high-performing but also aligned with a sustainable future.

The chillers are equipped with a robust control system that enhances operational performance and reliability. Features such as the advanced York YZ controller facilitate remote monitoring and diagnostics, allowing facility managers to optimize chiller performance and enhance maintenance processes. This advanced control capability minimizes downtime and maximizes productivity.

Noise reduction is also a significant consideration with these units. The WR series incorporates sound-dampening technology, making it an ideal choice for installations in noise-sensitive environments, such as schools or hospitals.

Furthermore, the construction of these chillers emphasizes durability and ease of maintenance. The components are engineered to withstand harsh operating conditions, and the design allows for straightforward access to key components, thereby simplifying service tasks.

In summary, the York WR300 and WR240 chillers stand out due to their energy efficiency, advanced refrigerant technology, robust control systems, and durability. These features make them ideal solutions for modern HVAC needs, supporting businesses while prioritizing environmental stewardship.
