Electric heating system

Gasco specialises in the design and supply of flanged element, electric heating systems for the heating of fluids. Flanged element heaters are used for:

  • Tank heating (liquids)
  • Pressure vessel heating (gases and liquids)

Both types of flanged heaters are available with Hazardous or Non-Hazardous area rating.
Gasco designs and manufactures the electric heater systems at its Head office in Melbourne Australia.

Hazardous Areas
Many industries, ranging from off-shore oil platforms, refineries, gas plants, tank farms and pharmaceutical, through to paint and chemical works have locations designated as hazardous areas where explosive atmospheres may exist.

Gasco design and manufacture heating systems that meet the highest standards for hazardous areas, and are certified to meet the most stringent requirements in the world: The IECEx Scheme.

The IECEX Scheme
The International Electrotechnical Commission (IEC) has established a scheme to facilitate international trade in electrical equipment, intended for use in explosive atmospheres. This is known as the IECEx Scheme.

Heating System Components
Electric Heating systems consist of three basic components:

  • Flanged Element bundle
  • Vessel or tank
  • Control panel

Gasco can design and provide all three components for a complete heating system solution.

Electric Element Bundles
The element bundle comprises of a main element flange, that enables the element bundle to be fixed to a tank or pressure vessel. The element bundle flange is fitted with the appropriate number and design of electric heating elements for the application. All Gasco’s element bundles undergo thermodynamic design, using globally recognised heat exchanger software. The elements and protection / control thermocouples are terminated inside an IECEx d flame proof terminal enclosure.

Pressure Vessels / Tanks
Pressure Vessels or static Tanks are used to house the element bundle.Pressure Vessels are manufactured to ASME Section VIII Div. 1, AS1210, and are designed to be compatible with mating piping systems. A full Manufacturing Data Report (MDR) is provided to our customers.

Tank contents may be heated using flanged elements at the base of the tank, and these may either have elements in direct contact with the contents or have an enclosed tube with indirect heating to enable withdrawal of elements for maintenance without the need to empty the contents of the tank

Control Panels
A well designed control panel is critical for efficient and accurate heater control. Gasco design and manufacture control panels to meet the specific demands of each of our customers, which could range from simple on/off switching to complex control systems using multi-layered inputs into a PLC/HMI system, with precise 0-100% Thyristor control.

Capital Costs

  • Electric heaters are simple in design and compact in size
  • They involve only a few static components, typically the element bundle, the vessel and the control panel
  • They generally surpass other heating systems, in controllability, efficiency and footprint
  • The capital cost is generally lower than other forms of heating

Running Costs

  • Electric immersion heaters are extremely efficient. They directly heat the product with infinite thyristor control, to the exact temperature set point
  • They are almost instantaneous in the delivery of heat to the process fluid
  • Therefore, no energy is wasted by the heater, in maintaining a base load level of heat
  • Other heating methods are less efficient, as they heat indirectly and experience greater losses
  • Flanged Immersion Heaters warrant serious consideration for most fluid heating applications
