n These coils can be used for fluid and CO2 circuiting.

n All controls are factory wired to a terminal strip for easy installation.

Optional Features and Accessories

n PSC fan motors.

n TEV (Thermostatic Expansion Valve) shipped loose or factory mounted.

n LLSV (Liquid Line Solenoid Valve) loose.

n SLHX (Suction Liquid Heat Exchanger) loose.

Defrost Methods

n Air or Off-Cycle for rooms above +34˚F.

n Electric for rooms -20˚F and above.

Specify When Ordering All Models

n Complete model number.

n Refrigerant R404A, R507, R407A, R407C, R407F, and R448A/R449A.

Standard Features

GH/GL Series Unit Coolers



Standard Features

n Ten inch diameter aluminum fans, direct driven at 1550 RPM, blow air uniformly through twin coils creating a low velocity “umbrella” air distribution.

n EC motors are standard for 115/1 and 230/1.

n Low and high silhouette models may be installed level and tight to ceiling. Hanger rods and TEV are internal resulting in a clean appearance.

n High efficiency coils, four rows deep with 3/8” diameter staggered copper tubes are mechanically expanded into corrugated aluminum fins spaced by tube collars. Direct expansion circuiting for halocarbon refrigerants is standard.

n Serviceable, textured aluminum housing features hinged orifice drain pan, pitched to drain condensate at end of unit.

n Low sound levels range from 53 decibels generated by one fan units to 60 decibels for six fan units, as measured on the “A” scale, six feet horizontally from the center of the unit.

n These coils can be used for fluid and CO2 circuiting.

n Capacity ratings are sensible heat removal with externally equalized TEV fed medium frosted coil.

Optional Features

n Insulated drain pan construction.

n Copper fins.

n Epoxy coating of entire tube and fin surface.

n Coils circuited for water or glycol fluids.

n PSC fan motors.

Optional Accessories

n TEV (Thermostatic Expansion Valve) shipped loose or factory mounted.

n LLSV (Liquid Line Solenoid Valve) loose.

n SLHX (Suction Liquid Heat Exchanger) loose or mounted.

n Washable Air Inlet Filters (Air Defrost only).

Defrost Methods

n AIR or OFF-CYCLE for rooms above +34˚F.

n ELECTRIC for rooms +20˚F and above (coil only – not available with vinyl coated fins or epoxy coated coil)

n GAS (KG-2 pipe) or (HG-3 pipe) for rooms above +32˚F.

n GAS (KGE or HGE) with electric drain pan booster heat for rooms +20˚ to +32˚F.

Specify When Ordering All Models

n Complete model number.

n Refrigerant.

n Room temperature.

n Optional features.

n Saturated suction temperature.

n Optional accessories.

Ideal for medium temperature low air circulation applications in spaces above +20˚F.
