SL210 series semi-automatic system is designed for a continuous supply of high purity and corrosive gases. It consists of a primary bank and a reserve bank of cylinders. Because of the differential pressure between the primary and reserve banks, the changeover takes place automatically when the primary bank is depleted to provide continuous supply of gas from the reserve bank. In order to activate the next switchover, the regulators on both banks need to be re-adjusted upon changing the cylinders. Stable pressure output is provided by the second pressure regulator on the main line.

- Use with R21SL regulators
- Metal-to-Metal diaphragm seal
- Pressure adjustment handle on regulator
- Gland check valves on pigtails
- Rear bracket mount

The SL250 Series switchover system is designed with Gentec's R21SL Series pressure reducing regulators to provide an uninterrupted supply of gas from two high pressure tanks. The system will automatically switch from the primary bank to the reserve bank without flow interruptions. An optional audible and visual remote alarm is available to power the indicator lights for the ayatem.

- Based on R21SL series regulators
- Metal-to-Metal diaphragm
- Components enclosed for extra protection
- Built in relief valve
- Check valves on pigtails
- Capable for visual alarm

Adjustable relief valves are designed for regulators as a protection for low-pressure components of systems sensitive to over pressurization. Adjustable ranges accomodate different application usages.

GENTEC PURGES are designed for use with high purity and corrosive gases to avoid contamination of system during component replacement or cylinder changes out. Gentec purges provide safety by preventing the release of corrosive or toxic gases into the environment. They also prevent corrosion of components by eliminating contact between corrosive gases and atmospheric air or moisture during cylinder changes.

Straight Purges - SL-P101

SL-P101 Straight Purge connects to the high-pressure ports on a regulator body. Purge Gas is vented through the low-pressure ports. This system is suited to both Pressure Cycle and Pulse Dilution methods.

Tee Purges - SL-P102

SL-P102 Tee Purge connects between a regulator and cylinder. Purge Gas is vented through the low-pressure ports. This system is suited for both Pressure Cycle and Pulse Dilution methods. Ideal for removing contaminants prior to start-up or after a cylinder change.

Cross Purges - SL-P103

SL-P103 Cross Purge connects between a regulator and cylinder. GENTEC Cross Purge provides efficient complete purge cycle by forcing the purging gas through the whole system (all the way through the inlet connection to the cylinder valve). It is also used to purge the cylinder connections or the entire regulator body. This system is suited for Pulse Dilution methods.

A pigtail connects between a regulator and cylinder with maximum inlet pressure of 3000psig. Pigtails are also suited for manifold systems.
