Tips to Select the Over the Side Heater

over the side heater

Over the side heaters are generally immersion heaters that hang on a tank’s side to heat the tank or the stuff within. An over the side heater can be used in conditions where heaters can’t be set up, portability is needed, or where heaters should be taken out for cleaning without vacating the tank. Also, these heaters can be used to stop freezing or to heat viscous substances to activate and increase the flow.

How to Select the Best Over the Side Heater?

Over the side immersion heaters, also known as tank heaters, offer a steadfast heat source for a variety of tanks. These heaters provide an excellent heating solution when adding immersion heaters into the tank’s wall is not a choice due to space restrictions or when heaters need to be removed without emptying the tank. So, here are some of the points based on which you can choose the best over the side heater:

Check Configurations

Over the side immersion heaters include a heating material encircled by a protective cover or sheath. Choosing an appropriate sleeve material is significant since the sheath is part of the heater that comes in touch with the process media. Care should be taken to make sure that the sheath material does not corrode, react, rust, or break down in the existence of the process media.

Sheath Material

Over the side immersion heaters differ in the sleeve materials and uses. Options you can go for sleeve or sheath materials are brass, aluminum, copper, fluoropolymer, high-temperature foil, nickel alloy, iron, polyimide, organic or synthetic rubber, steel or stainless steel.

Different Uses

Uses for over the side immersion heaters are the heating of vapors or gasses, clean water, process water, high-purity water, lightweight oil and degreasing solutions, heavy-weight and medium-weight oils, gentle and severe corrosive solutions, caustic solutions, as well as liquid paraffin. The heaters that are employed with caustic and corrosive solutions are sleeved or sheathed commonly in polymers, stainless steel, or high-durability alloys. 

Performance Requirements

Performance requirements for over the side immersion heaters are the highest operating temperature, needed AC voltage, heating capacity, phase, and watt density.

  • The highest operating temperature is the maximum temperature that the heater’s sheath might reach.
  • Some heaters utilize single-phase power, while others use 3-phase power.
  • Capacity to heat is the wattage that an over the side immersion heater can provide.
  • Watt density is a check of how fast the heater can transmit heat onto a heated area. To determine watt density, suppliers break down the available wattage by the heated area.

Look for Shapes

Over the side immersion heaters are offered in diverse shapes for various applications. The most general shapes are “O”, “L”, tube, and vertical loop.

  • L-form heaters are shaped similarly to the letter “L”.
  • O-heaters are generally circular in shape.
  • Vertical loops over the side immersion heaters possess an upright shape.
  • Tube heaters involve a single tube-like element.

Things to Know When Using Over the Side Heaters

  • Risky or hazardous location setup
  • Phase, voltage rating, and kW power rating
  • Applicable Amps at the place of installation
  • Time needed to reach the required temperature backdrop
  • Sensing pattern and temperature control
  • Amount of liquid or gas to be heated and if mixing or flowing
  • Thermal conductivity and viscosity of the fluid
  • The corrosive nature of the liquid
  • Heating vessel or tank cover’s type and thickness
  • Space restrictions for set up or heater evacuation
  • Indoor or outdoor setup

Features to Look For

Features for over the side heater are also a significant consideration. Options available are:

  1. Corrosion-proof
  2. Cryogenic usage
  3. Dynamic power adjustment
  4. Explosion-resistant
  5. Encased coil
  6. Internal temperature detector
  7. Finned
  8. Grounding wire
  9. Overheat safety
  10. Microprocessor-controlled
  11. Thermostat
  12. Portable
  13. Weatherproof housing
  14. UL approved

Dangerous location heaters are made for use in places where there is a condition of explosion or fire. UL or Underwriters Laboratories and different organizations rate these tools. Indirect-fired heaters employ a subordinate heat exchanger to take out the breathable airflow from the ignition airflow.
