FIELD-INSTALLED Accessories

262292-YTG-C-0707

NOTE: Knobs are shipped separately within the unit to prevent shipping damage. These must be field installed for tool free operation.

•HINGED/"TOOL FREE" BLOWER, BLOWER MOTOR, FILTER AND ELECTRIC ACCESS PANELS - This option allows for complete hinged and tool free access to the unit's blower, blower motor, filters and electrical panel sections.

•SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZERS - Includes a slide-in /plug-in damper assembly with fully modulating spring-return motor actuator capable of introducing up to 100% outdoor air with nominal 1% leakage type dampers.

The enthalpy system contains one sensor that monitors the outdoor air and determines when the air is cool enough and dry enough to provide free cooling.

The rainhood is painted to match the basic unit and must be field-assembled before installing.

•MOTORIZED OUTDOOR AIR INTAKE DAMPER - Includes a slide-in /plug-in damper assembly with a 2- position, spring return motor actuator which opens to some pre-set position whenever the supply air blower is operating and will drive fully closed when the blower unit shuts down.

The rain hood is painted to match the basic unit and must be field-assembled before installing.

Power exhaust is not available as a field installed option.

•ROOF CURBS - Fourteen-inch high roof curbs provide a water-tight seal between the unit and the finished roof. These full perimeter curbs meet the requirements of the National Roofing Contractors Association (NRCA) and are shipped knocked-down for field assembly.

They're designed to fit inside the base rails of the unit and include both a wood nailing strip and duct hanger supports.

•HIGH ALTITUDE NATURAL GAS - Burner orifices and pilot orifices are provided for proper furnace operation at altitudes up to 6,000 feet.

•PROPANE - Burner orifices, pilot orifices and gas valve parts are provided to convert a natural gas furnace to propane.

•HIGH ALTITUDE PROPANE - Burner orifices and pilot orifices are provided for proper furnace operation at altitudes up to 6,000 feet. This accessory supplements the basic propane conversion kit.

•SIDE DUCT FLANGES - One-inch flanges replace the supply and return air panels on the rear of the unit to accommodate horizontal duct connections. These flanges can also be used individually for bottom supply/horizontal return or horizontal supply/bottom return. They cannot be used on units with power exhaust.

•BAROMETRIC RELIEF DAMPER - This damper accessory can be used to relieve internal building air pressure on units with an economizer without power exhaust. This accessory includes a rain hood, a bird screen and a fully assembled damper. With bottom duct connections, the damper should be mounted over the opening in the return air panel. With horizontal ductwork, the accessory should be mounted on the return air duct.

•ENTHALPY ACCESSORY CONTROL KIT - This kit contains the required components to convert a single enthalpy economizer to dual enthalpy.

•BURGLAR BARS - Mount in the supply and return openings to prevent entry into the duct work.

•FLUE EXHAUST EXTENSION KIT - In locations with wind or weather conditions which may interfere with proper exhausting of furnace combustion products, this kit can be installed to prevent the flue exhaust from entering nearby fresh air intakes.

•WOOD SKID - Allows unit to be handled with 90” forks.

•CO2 SENSOR - Senses CO2 levels and automatically overrides the economizer when levels rise above the present limits.

•COIL GUARD - Customers can purchase a coil guard kit to protect the condenser coil from damage. This is not a hail guard kit.

•PHASE MONITORS - Designed to prevent unit damage. The phase monitor will shut the unit down in an out-of- phase condition.

WR 180 specifications

The York WR 180 is a state-of-the-art water-cooled chiller, renowned for its efficiency, flexibility, and reliability in various applications. Designed specifically for commercial and industrial use, the WR 180 stands out as an ideal solution for facilities requiring effective climate control, such as hotels, hospitals, shopping malls, and large office buildings.

One of the primary features of the York WR 180 is its advanced chiller design, which incorporates variable speed technology. This allows the unit to adjust its cooling capacity based on the actual load demands of the building, leading to significant energy savings. By operating at variable speeds instead of a fixed rate, the chiller minimizes energy consumption during lower demand periods while maintaining optimal performance during peak loads.

The WR 180 also employs a reliable and efficient centrifugal compressor, which contributes to its high energy efficiency ratio (EER). This compressor is designed to provide robust cooling while operating quietly, making it suitable for environments where noise reduction is essential. Additionally, the unit features a microprocessor-based control system that offers sophisticated monitoring and control capabilities, allowing operators to fine-tune performance and enhance reliability.

Another notable characteristic of the York WR 180 is its environmentally friendly refrigerant options. The chiller can operate with refrigerants that have a low global warming potential (GWP), aligning with international regulations and environmental sustainability goals. This commitment to eco-friendly designs not only helps reduce the carbon footprint but also ensures compliance with industry standards.

In terms of installation and maintenance, the WR 180 is designed for user-friendliness. Its modular design simplifies transport and installation in various spaces, while easy-access components facilitate routine maintenance. The chiller also offers various connectivity options, enabling integration with building management systems for real-time monitoring and control.

Overall, the York WR 180 combines innovative design, cutting-edge technology, and eco-friendly practices, making it a top choice for industries seeking efficient and sustainable cooling solutions. Its impressive features, coupled with strong operational flexibility, position the WR 180 as a leader in the chiller market.
