3 phase, _____ Hz.

Dual Glycol Pump Package (Optional)

The dual pump package shall include pumps, enclosure, and field mounted flow switch. The pumps shall be wired to the drycooler control box which includes a lead/lag switch for the pumps. The standby pump shall automatically start upon failure of the lead pump. Each pump shall be rated for

_____ GPM (l/s) at _____ feet of head (kPa).

2.3Direct Expansion Split Systems

Direct Expansion Coil

The evaporator coil shall have _____ sq.ft. (sq. m) face area, _____ rows deep. It shall be configured as

(A)(V) frame and be constructed of copper tubes and aluminum fins and have a maximum face veloc- ity of _____ ft. per minute (m/s) at _____ CFM (CMH). The coil shall be provided with a stainless steel drain pan.

Refrigeration System

The refrigeration system shall consist of a rugged scroll compressor, pressure safety switches, exter- nally equalized expansion valve, filter dryer, and a refrigerant sight glass and moisture indicator.

Centrifugal Fan Condensing Unit

The condenser coil shall be constructed of copper tubes and aluminum fins. The condensing unit shall be factory assembled, charged with refrigerant and sealed.

Components shall include scroll compressor, high-pressure switch, Liebert Lee-Temp refrigerant receiver, head pressure control valve, and liquid line solenoid valve.

The condensing unit shall be designed for 95°F (35°C) ambient and be capable of operation to -20°F (-29°C) ambient.

A hot gas bypass circuit shall be provided to reduce compressor cycling and improve operation under low load conditions.
