Low-loss fittings on recovery equipment help compliance by:
a.Increasing recovery pressure
b.Testing refrigerant purity
c.Cooling the cylinder
d.Reducing the refrigerant lost when hoses are connected and disconnected
Giải thích
Low-loss fittings close off automatically to release as little refrigerant as possible each time you connect or disconnect hoses, cutting emissions on every job. They do not test purity, cool cylinders, or raise pressure. Using them is good conservation practice across all refrigerant work.
