Heatpump - Casing <br />- Zinc coated, heavy gauge, galvanized steel. <br />- Weather resistant pre-painted metal with galvanized substrate. <br />- Meets ASTM B117, 672 hour salt spray test. <br />- Removable single side maintenance access panels. <br />- Lifting handles in maintenance access panels (can be removed and reinstalled by removing fasteners <br /> while providing a water and air tight seal). <br />- Exposed vertical panels and top covers in the indoor air section insulated with a cleanable foil-faced, <br /> fire-retardant permanent, odorless glass fiber material. <br />- Base pan shall have no penetrations within the perimeter of the curb other than the raised 1 inch high <br /> downflow supply/return openings to provide an added water integrity precaution, if the condensate <br />drain backs up. <br />- Base of the unit insulated with 1/8 inch, foil-faced, closed-cell insulation. <br />- Unit base provisions for forklift and/or crane lifting on three sides of unit. <br />Heatpump - Coils Evaporator and Condenser <br />- Internally finned, 5/16" copper tubes mechanically bonded to a configured aluminum plate <br /> fin are standard. <br />- Coils are leak tested at the factory to ensure integrity. <br />- Evaporator coil and condenser coil are leak tested to 600 psig. <br />- Assembled unit is leak tested to 465 psig. <br />- Condenser coil is patent pending 1+1+1 hybrid coil, designed with slight gaps for cleaning ease. <br />- Composite, dual-sloped, removable condensate drain pan is standard. <br />Heatpump - Coil Guards <br />- Provides condenser coil protection. <br />Heatpump - Compressors <br />- All units have direct-drive, hermetic, scroll type compressors with centrifugal type oil pumps. <br />- Suction gas-cooled motor with voltage utilization range of plus or minus 10 percent of unit <br /> nameplate voltage. <br />- Internal overloads standard with scroll compressors. <br />- Crankcase heaters are standard on all compressors. <br />- All units have dual compressors. <br />- Three stages of cooling available on 12.5 to 17.5 tons units and four stages of cooling available <br /> on 20 and 25 tons units. <br />Heatpump - Filters <br />- Standard throwaway filters <br />- Optional 2 inch MERV 8 and MERV 13 filters <br />Heatpump - Frostat <br />- Utilized as a safety device. <br />- Opens to prevent freezing temperatures on evaporator coil. <br />- Temperature will need to rise to 50.0 F before closing. <br />- Utilized in low airflow or high outside air applications (cooling only). <br />Heatpump - Low Leak Economizer <br />- This accessory meets the low leak requirements for ASHRAE 90.1, IECC, and CA Title 24 standards <br /> (4 cfm/ ft2@1" wg exterior air/return air). This option allows for 100% outdoor air supply from 0% to <br /> 100% modulating dampers and comes standard with barometric relief. It can be paired with powered <br /> exhaust for additional building pressure relief. This option can be paired with or without fault detection <br /> and diagnostics (FDD) to meet the current mandatory CA Title 24 requirements. The economizers <br /> come with four control options: dry bulb, reference enthalpy, comparative enthalpy, or differential dry <br /> bulb. <br />Job Name: Arctic Cooling Systems - RFQ <br />Prepared For: <br />Unit Tag: HP-1 <br />Quantity: 1 <br />2025/02/13 18:49:34 Page 7 of 7
