Noise-reduction features: Constructed with 1-inch, closed-cell, elastomeric foam insulation and ECM plenum fans, the EZ-Fit provides quiet and efficient operation. Each compressor is mounted on rubber vibration isolators and comes with a factory-provided compressor acoustic cover.

IAQ equipment supported: The unit provides fresh air ventilation, and high-efficiency MERV 8 pre- and MERV 13 final filters are standard.

Thermostat compatibility: Marvel premium microprocessor with BACnet.

Replacement parts compatibility: Shares replacement parts with other models.

Additional features: The modular cabinet has been designed to ship in multiple sections for ease of maneuvering throughout the building. All sections fit through a standard 36-inch doorway and easily assemble on site. Single modules (3,000 to 10,000 CFM) can be twinned as a dual module for higher capacities and CFMs (up to 21,000 CFM), with single point power and single water connections. All units ship with a complete R-410A refrigerant charge.

Warranty information: Five-year compressor and one-year parts warranty.

Special installation requirements: Manufacturer did not specify.

Serviceability features: Aurora advanced controls offer electronic expansion valve and modulating water valve control, true energy monitoring, refrigeration monitoring, and optional performance monitoring.

Noise-reduction features: Cabinets utilize a compact footprint, and all interior surfaces are lined with ½-inch thick, foil-lined, acoustic-type, fiber insulation, which helps reduce noise into the space. Product utilizes quiet variable-speed compressors with optional sound blanket.

IAQ equipment supported: Manufacturer did not specify.

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Some shared parts and some unique parts.

Additional features: Easily fits through standard 36-inch door and small freight elevators. Installs faster with single point power, eliminating the need to rewire existing electrical systems. No need to break the refrigeration circuit, or ship the compressor/fan coil separately, because the unit is self-contained. Easy install with modular design eliminates need for temporary cooling/heating during changeover. The variable-speed unit varies itself between 25%-100% capacity, resulting in the most efficient and comfortable conditioning possible.

Warranty information: Standard 18-months parts-only warranty. Optional extended compressor and refrigerant circuit warranties.

Special installation requirements: Manufacturer did not specify.

Serviceability features: The YVWH-200 heat pump features an intelligent, touchscreen control panel designed to simplify operation and serviceability. Additionally, the Smart Equipment-enabled YVWH seamlessly connects to building control systems, such as OpenBlue, to maximize system insight and streamline maintenance.

Noise-reduction features: These heat pumps feature advanced variable-speed drive compressors that optimize performance and maintain lower sound levels.

IAQ equipment supported: Manufacturer did not specify.

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Some shared parts and some unique parts.

Additional features: The YVWH-200 heat pump is engineered to significantly reduce energy use, water consumption, and carbon emissions within facilities that require heating, cooling, and simultaneous heating and cooling functions. The industry-leading heat pump delivers up to 176°F hot water while simultaneously producing chilled water at 41°F. Combined with a turndown capacity as low as 25%, the YVWH-200 is three times more efficient than a typical boiler and four times more efficient than traditional boiler and chiller systems.

Warranty information: Manufacturer did not specify.

Special installation requirements: The heat pump offers maximum scalability and decarbonization within a wide range of applications. Multiple units can be combined based on the facility demands, or YVWH can work in parallel with other YORK water-to-water heat pumps like the CYK to increase capacity and application benefits.
