Table 1 — 30MPA Air-Cooled and 30MPW Liquid-Cooled 016-045 Units Physical Data — English
*
30MPA units (condenser-less) are shipped with nitrogen holding charge.
Approximate cooler operating charge is shown.
†
With optional hot gas
b
ypass.
**
Models 016 and 032 are not availa
b
le in an air-cooled version.
NOTES:
1. Operating weight includes refrigerant operating charge and weight of fluid
in the heat exchangers.
2. Manifold option adds approximately 218 l
b
to the operating weight of
30MPA units and 436 l
b
to the operating weight of 30MPW units.
3. 30MPW units are shipped with full operating charge.
