Table 3 — 30MPA Air-Cooled and 30MPW Liquid-Cooled 016-045 Units Physical Data — SI
*
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 99 kg to the operating weight of
30MPA units and 198 kg to the operating weight of 30MPW units.
3. 30MPW units are shipped with full operating charge.
