Table 4 — 30MPA Air-Cooled and 30MPW Liquid-Cooled 050-071 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.
NOTES:
1. Operating weight includes refrigerant operating charge and weight of fluid
in the heat exchangers.
2. Manifold option adds approximately 98.9 kg to the operating weight of
30MPA units and 197.7 kg to the operating weight of 30MPW units.
3. 30MPW units are shipped with full operating charge.
