Changeover Systems for Gas Cylinder
Manual Changeover System
FDR-1 Series Manual Changeover System (up to 500 psig).
◎ A small manual changeover system with a regulator similar to FCR-1
Series Regulators
◎ Connecting with two independent gas sources at a time, gas source
selected through diaphragm valves
FDR-2 Series Manual Changeover System (up to 2500 psig).
◎ A small manual changeover system with a regulator similar to FCR-2 Series Regulators
◎ Connecting with two independent gas sources at a time, gas sources switched through diaphragm
Automatic Changeover System
CEPR Series Series Automatic Changeover System
The CEPR series automatic changeover system, suitable for uninterrupted gas supply, uses dual gas sources of main supply cylinder and backup cylinder. When the pressure of one gas source drops below the set pressure, the changeover system will automatically switch from the depleted source to the backup source, thus achieving a continuous gas supply.
Features
◎ Two gas sources are connected to regulators of the automatic changeover system, when the pressure of one gas source is lower than the switching pressure, it will automatically switch to the other gas source to supply gas, thus ensuring continuous gas supply
◎ Excellent sensitivity and set point pressure stability.
FDR-1L Series Automatic Changeover System without Line Pressure Regulator
Features
◎ With 2 regulators similar to FCR-1 Series Regulators
◎ Anodized Aluminium box with clearly marked panel
◎ With vent valves to relieve residual pressure quickly,easy and safe to remove and replace gas source
◎ Automatic switching of gas source to ensure continuous gas supply
◎ Four fixed outlet pressure ranges available
◎ With special cleaning and packaging, applicable to oxygen-enriched environments

FDR-1T Series Automatic Changeover System with Line Pressure Regulator
FDR-1T Series Automatic Changeover System with Line Pressure Regulator.
Features
◎ With a FCR-1 Series Regulator and a FLR-1 Series Regulator to enable outlet pressure adjustment
◎ Anodized Aluminium box with clearly marked panel
◎ With vent valves to relieve residual pressure quickly,easy and safe to remove and replace gas source
◎ Automatic switching of gas source to ensure continuous gas supply
◎ With special cleaning and packaging, applicable to oxygen-enriched environments
Operation Overview
The FDR-1T Series Changeover System is mainly comprised of one adjustable outlet pressure regulator and one fixed outlet pressure regulator, together with a line pressure regulator on the outlet port.
When the 2 inlets are both open, the one side that the “IN SERVICE” arrow is pointing at by turning the handle would be the 1st source for gas supply.
