Table 2 — 30MPA Air-Cooled and 30MPW Liquid-Cooled 050-071 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.
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.
