Small Size and Easy Installation Electric Heater for Compressed Gas

Product Specification

Small Size and Easy Installation Electric Heater for Compressed Gas adopts the principle of fluid thermodynamics to uniformly take away the huge heat generated at the work of electric heating elements, so that the temperature of the heated medium can meet the user's technological requirements. Many liquefied gases cool dramatically under even moderate flow conditions due to the heat of vaporization when the liquid is converted to gas. This effect causes "freezing" in pressure regulators and other equipment resulting in pressure and flow fluctuations.

Compressed gas electric heater product features:

1, heating fast, uniform, no temperature dead zone, high thermal efficiency

2, small size, easy installation, can be designed according to user requirements, vertical or horizontal installation can be realized.

3, long life, using multiple safety protection, safe and reliable.

4, the application range is wide, can be suitable for explosion-proof occasions or ordinary occasions, explosion-proof grade up to B and C.

Compressed gas electric heater product application:

Products are widely used in power plants, petroleum, oil production, chemical industry, military industry, aerospace, offshore platforms, air, natural gas, methane chloride, heat conduction oil and other gases heating.

Technical Properties

1. The gas electric heater uses mineral insulated (MI) heating cable as heating element to transfer heat to the heat exchange chamber via a heat medium. The heat between the heated medium and the heating element are indirectly transmitted.

2. The heated gas is guided to flow along the sparger in the heat exchange chamber, and has a good flow heat exchange effect.

3. A temperature sensor being set at the outlet of the heat exchange chamber, the temperature automatic control can be realized after being connected with the matched temperature control cabinet.

4. The conventional pressure grade of 0.6~12MPa can be designed and produced, and higher pressure (12~25MPa) grade can also be done for professional users.

5. In explosion-proof locations, device connections and electrical wiring are in compliance with explosion-proof specifications with an explosion-proof rating dIIB T1-T6.

Working Principle

The cold medium enters the heat exchange chamber via the inlet pipe, guides the tortuous turbulence along the baffle plate, and flows to the outlet pipe at a uniform temperature after a predetermined heat exchange process. A temperature sensor being installed in the outlet pipe of the heat exchange chamber and the temperature signal being collected and transmitted to the electrical control system, the primary circuit electrical component is controlled by the temperature regulator to realize automatic temperature control. At the same time, it is equipped with a flow lockout device to stop automatically the power output of the electric heating element when the medium flow is relatively small while to resume the normal heating by increasing the flow rate immediately and an over-temperature protection device is provided.
