Factory insulation — Thermal insulation is factory- provided to the following areas:

•Cooler (not including waterbox)

•Suction line

•Compressor and motor

•Oil cooling line and oil return system line (oil and refrig- erant lines at or near evaporator pressure are insulated)

•VFD cooling line (oil and refrigerant lines at or near evaporator pressure are insulated)

•Motor cooling line

•Vaporizer

•Liquid line and discharge line

•Float chamber

•Optional economizer (including vent line and econo- mizer muffler)

Factory insulation is not available for the waterboxes.

Insulation applied at the factory is 1/2-in. (13 mm) thick closed cell and 1/2-in. (13 mm) open cell PVC-Nitrile foam. Some parts of the chiller are also treated with an outer layer of 3/16-in. (5 mm) thick vinyl. The 1/2-in. (13 mm) closed cell foam has a thermal conductivity K value of 0.28 (BTU in.)/(hr sqft °F) [0.0404 W/(m °C)] and

conforms with Underwriters Laboratories (UL) Standard 94, Classification 94 HF-1. Both the 1/2-in. foam and the 3/16-in. vinyl layer will pass flammability test method MVSS 302.

Field insulation — As indicated in the Condensation vs Relative Humidity table, the factory insulation provides excellent protection against condensation under most op- erating conditions. If temperatures in the equipment area exceed the maximum design conditions, extra insulation is recommended.

If the machine is to be field insulated, obtain the approx- imate areas from the 23XRV Minimum Field-Installed Insu- lation Requirements table.

Insulation of waterbox is made only in the field and this area is not included in 23XRV Minimum Field-Installed In- sulation Requirements table. When insulating the covers, allow for service access and removal of covers. To estimate water-box cover areas, refer to certified drawings.

High humidity jobsite locations may require field sup- plied and installed insulation on the float chamber, suction housing, and the lower half of the condenser.

*These approximate figures are based on 35 F (1.7 C) saturated suction temperature. A 2° F (1.1° C) change in saturated suction temperature changes the relative humidity values by 1% in the same direction.

→Minimum fluid loop volume

Minimum fluid volume must be in excess of 1.5 gal per ton (20 L per kW) for comfort cooling applications and apply 3 to 5 gal per ton (40 to 66 L per kW) fluid loop volume for process applications.
