Immersion & Tank Heating

Electric immersion heaters are extremely useful in many applications. High heating efficiency and accurate control are maintained due to the heat being generated within the solution.

These elements are easily installed and are often used to heat liquids, viscous materials and solids with low melting points. Some common substances include solvents, oil, water, plating baths, salts, wax, paraffin, asphalt and molasses.

Design of shape, sheath and mounting can also be specific to the application. The heat absorption rate of substances will often determine the heat intensity (watt density) of the element. Usually low or mild heat is used for oils and soft metals and more intense heat is required for water and salts.

For accurate temperature control a thermowell is fitted which then enables single or 3 phase thermostat inclusion.

Most of our product range is manufactured with 316, 321 stainless steel or Incoloy 800 element sheaths. However, Thermal can design specific heaters with different sheaths (such as Titanium or Lead), shapes, sizes, wattages and voltages as required for your application.

The heater mounting can also be designed to suit the application and vessel accessibility.

Types of Immersion Heaters

The most common methods of applying heat to a tank or vessel’s contents without limiting work area are:

  • Bitumen – For bitumen and asphalt storage and processing
  • Screw in – for small to medium size containers
  • Over the Side – a heavy duty element for portable situations
  • Withdrawable – tubular or ceramic bobbin
  • Clean in Place (CIP) – used for tank cleaning
Bitumen

Bitumen & Asphalt

Vulcanic TEE designs and manufactures custom immersion heaters for the Bitumen and Asphalt industries to be used in various applications including storage containers and tanks and onboard the spray trucks.

Bitumen storage heating bundles are used to maintain fluidity in storage containers and tanks.
Specialised heating bundles are also used onboard the road spraying trucks to ensure the flow of the product.

Vulcanic TEE’s unique black heat design guarantees maximum heating efficiency without burning the bitumen product. Our low watt heaters have been very successful due to their reliability and their ability to stop heat transfer into the terminal⁄control enclosure.

Screw in

Screw In Type

Suitable for small and medium sized containers. The tubular elements are brazed or welded into a BSP bush and a terminal housing is provided for electrical connections.

INSTALLATION: The heater is screwed into a female BSP fitting in the tank or into a pipe coupling or half coupling.

APPLICATIONS: Hot water storage, fluid heating – eg. tar, asphalt, wax, oil, caustic soda, detergent, sterilising equipment, gases.

FEATURES: A compact heater for areas where over the side heaters cannot be used, for example, closed in tanks.

OPTIONS:

  • can be manufactured in stainless steel, Incoloy or Titanium
  • various wattages and voltages
  • various element diameters
  • several BSP bush sizes available – ranging from 3/8″BSP to 4″BSP
  • assorted shapes – eg. trombone, u-shaped, triple loop, fold back, coiled
  • several termination varieties available
  • 3 phase, Star or Delta wiring options available
Over the Side

Over The Side

Portable over the side immersion heaters are compact and portable enough to move from tank to tank and guarantee minimal interference with the production process. They can easily be re-positioned along the tank wall to improve heat distribution and are ideal where removal of the heater is required for periodic cleaning and inspection of the tank.

These heaters are available for heating water, light weight oils, salt baths, alkaline cleaning solutions, cyanide plating solutions, citric juices, acid baths and other corrosive liquids.

Standard units up to 4000W come complete with terminal enclosure and thermostat control. If our stock range of heaters are not suited to your application, then custom manufactured units can be made available to suit your requirements.
INSTALLATION: Simply place over side wall of tank.

FEATURES:

  • Portable
  • Economical
  • Ease of maintenance

APPLICATIONS: Heating all solutions where drainage of the tank is impractical.

OPTIONS:

  • can be manufactured in stainless steel, Incoloy, Titanium or Lead
  • various wattages and voltages
  • various element diameters
  • terminal enclosure fully moisture resistant
  • rubber seals
  • 3 phase, Star or Delta wiring available
  • digital temperature controls
  • programmable timers
  • various watt densities

Hot Sticks

A Hot Stick is an over the side immersion type heater available in Stainless Steel, Vitrosol (Quartz) or Titanium sheaths. Teflon immersion heaters are also available as well as guards to suit all units.
Hot Sticks are available as separate parts or sold complete with the range including Mini Hot Sticks, controls, probes and accessories.
These Hot Sticks are ideal for use in electroplating, metal finishing and the chemical industry.
Mini Hot Sticks are ideal for use in smaller applications including PC board production, fish tanks, labs and jewellery industries.
Guards are available in both PVC and Polypropylene depending on temperatures used.
Thermostats, PT100 temperature controls and liquid level sensing probes are also available.

Heat Coils

The Heat Coil series of heaters are designed for use in the chemical, electroplating and metal finishing industries. A robust design with heaters being manufactured from 316SS, Incoloy and Titanium sheaths ensuring a long lasting reliable and hassle free package.

Teflon Sleeved

Used in solutions where previously only Vitrosol or Quartz heaters were available. No fragile sheaths, no cracking or breakages. A reliable and rigid Incoloy metal sheathed element with a non contaminating, chemical resistant Teflon sleeve. A 0.75mm wall thickness of teflon gives a safe barrier between the solution and the heating element.

Teflon Heat Coils are compatible with most plating tank solutions and are impervious to acids, pickling and anodising solutions up to 90°C.

OPTIONS:

  • SS terminal/control enclosures
  • standard or digital temperature controls
  • various voltages and wattages available on request
  • 90° angled terminal enclosure to tank
Withdrawable

Withdrawable Type

Tubular

SS sheathed alternative to the standard ceramic bobbin type. The withdrawable tubular has been designed and manufactured to outlast its ceramic counterpart, which is fragile and will deteriorate much sooner through physical damage. Tubular withdrawables are suitable for applications where replacement or repairs are to be carried out without disturbing the contents of the tank.

INSTALLATION: This is achieved by inserting the withdrawable tubular heater into a nominal diameter tube – commonly known as the thermowell – ranging from 50mm diameter for standard units, up to 100mm diameter for specials. The thermowell may be the permanent fixture of the tank or it can be supplied as a separate removable tube with 2″BSP boss which can then be fitted to a mating tank socket.

FEATURES: Robust, suitable for harsh conditions and extremely resistant to mechanical or physical abuse, or where vibration may occur.

APPLICATIONS: Suitable for all solutions where drainage of the tank is impractical and where direct heating is not achievable or recommended. Materials such as bitumen, wax, fats and oils require low element surface temperature to prevent product degradation.

OPTIONS:

can be manufactured in stainless steel or Incoloy
various wattages and voltages
various element diameters
can be manufactured to Zone 1 Class 1 standards
several terminal variations

Ceramic Bobbin

A low cost alternative to the SS tubular type and also suitable for applications where replacement or repairs are to be carried out without disturbing the contents of the tank.

INSTALLATION: Is achieved by inserting the ceramic bobbin into a 50mm nominal diameter tube – commonly known as the thermowell. The thermowell may be a permanent fixture of the tank or it can be supplied as a separate removable tube with 2″ BSP boss which can then be fitted to the mating tank socket.

APPLICATIONS: As per withdrawable tubulars.

Please note Ceramic Bobbins are MADE TO ORDER ONLY.
