LPG is consisted of pressure adjusting box, heat exchanger and level display with protection system. The equipment changes the heat transfer area by automatically adjusting the level to adapt the change in the production load. When the load is over high and the level raises the high-point, the float valve automatically turns off the gas exit which is avoid of liquid-off phenomenon and ensure the safe operation of equipment.

This equipment uses the decompressed vaporization principle. The LPG liquid from holding tank or low temperature insulation cylinder reduces the pressure by the pressure adjusting box. The liquid LPGs temperature descends which makes the large difference in temperature between itself and environment to increase the speed of heat transporting. Then enter the finned tube evaporator makes the liquid become gas. The hot gas in the overheating part by the level control machine raises the temperature of exit gas to achieve the efficiency of steady transportation.

Level display and protection system is consisted by the magnetic liquid level gauge cut-off device (contains safety valve) and long distance early warning system (optional). The level of Level gauge is visual. When the liquid reaches the high point, the early warning system will warn the worker. When the level is over the point of no return, Liquid cut off device will turn off the gas exit automatically in avoid of liquid gauge LPG come into the pipe. The float valve needs the manual reset after it turned off.
