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 banks. 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 system.
