Ring Type Evaporative Units for LPG

Indirect Electric Heating

The evaporative unit is designed to evaporate liquefied petroleum gases of propane, butane and their mixtures and supply the vapour phase to consumers.

One of the many advantages of this evaporative unit, as compared to evaporators and evaporative units of other manufacturers, is its small size design, which in turn saves money and time significantly while designing and installing equipment at the facility. The installation of an evaporative unit takes no more than two hours, from mounting on the neck to commissioning, because there is no need to install an understructure and lay additional pipelines with the necessary shut-off and relief valves for installation, for example as in the cabinet type models.

According to the customer’s request, the unit can be equipped with a medium or a low pressure regulator with safety/relief and shut-off valves, with speed or check valves, with spark quenchers and insulating flange kits.

The electrical design of the unit complies with the VDE and ATEX regulations and is approved for installation within the EX II explosion hazardous area.

The unit’s electrical control panel is located directly in the cavity of the neck’s protective casing.

Indirect Liquid Heating

A distinctive feature of this unit is that it can be controlled without using electricity (basic design).

The evaporative unit is supplied with a tank neck’s DN 500 lid. When ordering the evaporative unit, a customer should provide a detailed drawing of the mating ring for fixing a gas storage tank’s lid.

The unit’s basic design includes all the necessary components for an off-line operation.
