When there are two cylinder lines, changeover from line-A to line-B for replacement is always required. Liquid Changeover LR switches active line from line-A to line-B automatically by detecting pressure
Space-saving compact size allows more freedom for installation.
SNAP REVERSE STRUCTURE
Red arrows indicates which line is in use. changeover activation status can be checked easily by color indicator.
LR functions with “Snap Reverse Structure” to achieve dust-proof and rain-proof construction. The simplest and most reliable form of liquid automatic changer realizing highly accurate and instantaneous changeover operation.
EASY MAINTENANCE STRUCTURE
Simple structure allows disassembly and assembly to be performed easily at the site.

- Explosion-proof Signal Transmitter Switch (Optional)
With Signal Transmitter Switch, the actuation of LR could be verified under remote monitor through a telephone line
Control circuit : 220V
- LPG consumption should be lower than the LR standard capacity indicated above
- If the LR inlet pressure requirement could not be adapted, it might be necessary to change the LPG composition
