Energy-saving, precision design: extends
compressor motor life, saves on operating
costs, increases electrical efficiency

Hermetic design
Hermetic compressor design keeps
motor free of airborne dirf and mois
ture. It also isolates motor to keep heat
and sound from equipment room.
Eliminates shaft seal with its potential
refrigerant leakage.
■ Gear driven compressors
Gear driven compressors allow more
flexibility in selection than direct drive
because gear ratios can be fitted to
particular application. Gear driven
compressors also allow optimum im
peller speed, higher head applications
and increased operating efficiency.
Multi-pass water boxes
The complete 19 Series line offers 1,2,3
and 4 pass water boxes on both the
coolers and condensers. The result is
better heat transfer when needed —
reducing operafing costs. In addition,
all pass arrangements are available at
no extra cost.
Refrigerant-cooled motor
All 19 Series compressors have
refrigerant-cooled motors that operate
at low, even temperatures throughout
the motor windings to insure long motor
life at high electrical efficiency.
