Electric Immersion Heaters

Electric Immersion heaters are extremely useful in many applications. High heating e�ciency and accurate control are maintained due to the heat being generated within the solution.Immersion heaters 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, para�n, asphalt and molasses.

Design of the shape, sheath and mounting are speci�cally tailored 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 �tted which then allows for single or 3 phase thermostat inclusion.

Most of our product range is manufactured in stainless steel or Incoloy element sheaths. Thermal can, however, design speci�c heaters with di�erent sheaths (such as Titanium), 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 method of applying heat to tank or vessel contents withoutlimiting work area are: Screw In - For small to medium size containers Over The Side - A heavy duty element for portable situations Withdrawable - Tubular or Ceramic Bobbin

Over The Side Heaters

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.

Over the side 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 produced to suit your requirements.

InstallationSimply place over side wall of tank.

Withdrawable Type - Tubular

Stainless Steel 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.

InstallationThis is achieved by inserting the withdrawable tubular element into a nominal diameter pipe - commonly known as the thermowell - ranging from 50mm diameter for standard units, up to 100mm diameter for specials. The thermowell may be a permanent �xture of the tank or it can be supplied as a separate removable tube with 2” BSP boss which can then be �tted to a mating tank socket.

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

ApplicationsSuitable 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 temperatures to prevent product degradation.

Options Can be manufactured in Stainless Steel, Incoloy or Titanium Various wattages and voltages Various element diameters Can be manufactured to Zone 1 Class 1 standards Several terminal variations

Thermal Heat Coils

The Heat Coil series of heaters are designed for use in the chemical, electroplating and metal �nishing industries. Boasting a robust design, heat coils are manufactured from 316SS, Incoloy and Titanium sheaths ensuring a long lasting, reliable and hassle-free package.

Te�on Heat Coils are used in solutions where previously only Vitrosol or Quartz heaters were available. Now a solid package is here! No fragile sheaths, no cracking or breakages. A reliable and rigid metal sheathed element within a non-contaminating, chemical resistant Te�on sleeve. A 0.75mm wall thickness of Te�on gives a safe barrier between the solution and the heating element.

Te�on Heat Coils are compatible with most plating tank solutions and are inert to acids, pickling and anodising solutions up to 90°C.

Optional extras Chemical resistive terminal/control enclosures Analog or digital temperature controls

ELEMENT

The Hot Stick range of heaters is made for use in the electroplating, metal �nishing and chemical industries.It is an over the side type heater and is available in three di�erent sheaths - Quartz, Stainless Steel and Titanium.The main criteria for selecting the appropriate Hot Stick is to know what solution it will be heating. Pleasecontact us to determine the correct sheath material required for your application.The wattage required to heat the load to the desired temperature in an acceptable amount of time must also be determined as well as the depth of the tank being used and the level of the liquid being heated. The heated section must be covered by liquid at all times (refer to page 10.18).The following table shows the Hot Sticks dimensions and accompanying elements.

A typical installation will require the following selections to be made:For example, when ordering a 3kW Vitrosol Hot Stick for a 1000mm deep tank the following parts need to be ordered: Vitrosol sheath (1000mm) - HSVS1000 Element (3kW) - HSE30-1000 Lead assembly (2m long) - HRC2 Other components to consider: Heater guard (PVC or Polypropylene - see below) Mounting bracket (over page) Liquid level and temperature control (if required, see page 10.18)

Heater GuardsVitrosol (Quartz) HSVS and coiled Te�on HSTEFE sheaths require a fully enclosed protective guard.Use PVC for solutions below 70°C and Polypropylene for solutions up to 100°C. (Except for chrome and nitric solutions)

Mini Hot SticksFor other applications where smaller immersion heaters are required there is a Mini Hot Stick range available. These applications may include: PC board production, large �sh tanks, laboratories, pilot plants and the jewellery industries.Mini Hot Sticks are supplied complete with their in-built heating element and PVC mounting bracket.

Te�on over the side Immersion HeatersIt is recommended that a fully enclosed guard be used to protect Te�on heaters, where mechanical damage may occur.If this is not an issue, heaters can be installed with supplied PVC mounting bracket and stainless steel bolts. *Average sheath watts density for Coils & Banjos is 16kW/m²
