Nominal Horsepower Rating Basis

15,000 Btu per hour @ 85°F. inlet water, 0.00025 additive fouling factor (total .0005) and 105°F. condensing temperature, with approximately three gallon per minute (gpm) water low and refrigerant 22.

Pumpdown Capacity

Pumpdown figures have been compensated to provide capacity for R-22 based on 80% of condenser volume filled with liquid at 90°f.

Operating Charge

Approximately 10% of the pumpdown capacity is required in the unit for proper operation.

Nominal Water Pressure Drop

Nominal pressure drops (psi) given are at nominal low rates. To determine nominal low rates, multiply nominal horsepower (hp) by 3.0. Water pressure drops provided do not include any external fittings or valves.

Water Flow

Velocities of eight feet per second or higher risk premature impingement corrosion and tube failure. Operation below minimum low rates may result in excessive fouling and poor heat transfer. All values in this catalog section are limited to lows below eight feet per second.
