GEM Series combo pressure build – economizer regulators offer optimum performance for cryogenic liquid cylinders. Designed for fast pressure building, steady head pressure during all use conditions, and maximum efficiency economization when cylinder pressure is near the relief valve setting.
The pressure-build and economizer functions are completely separated, eliminating function overlap and improving overall cylinder efficiency. Solid, non-tied diaphragm and inlet filter screen provide leak-free, long-lasting, and reliable performance. All GEM Series regulators are factory pre-set and cleaned for oxygen service.
- Optimized for Cryogenic Liquid Cylinders: Designed to exceed PB and Economizer performance of current market offerings
- Separate PB and Econ Functions: Eliminates overlap between pressure build and economizer functions for improved cylinder efficiency
- Maximized Economizer Flow: Designed for maximum economizer flow performance, minimizing product loss
- Solid, Non-Tied Diaphragm: Eliminates potential leak path and increases device sensitivity
- Inlet Filter Screen: Protects regulator from system debris for reliability and long life
- Cleaned for Oxygen Service: Regulators are cleaned for use in Oxygen service standard
