Immersion Heaters

Immersion heaters are used to maintain or raise the temperature of fluids in tanks or process vessels. These heaters are installed below the tank outlet to remain fully submerged, ensuring uniform heating. They are widely used in Industrial Oil Tank Cleaning Services, Fuel Filtration and Polishing Services, and Underground Tank Cleaning Robots.

Types of Immersion Heaters:

  • Direct Heating – Tubular Heaters: For direct contact with liquids or gases, offering nearly 100% heat transfer.
  • Indirect Heating – Cartridge Type: Ideal for viscous liquids and corrosive solutions, with replaceable cartridge elements for easy maintenance.

Mounting Options:

  • Threaded Screw Plug
  • Flange – Standard and Customized
  • Over-the-Side Installations

Benefits:

  • Energy-efficient and precise temperature control
  • Wide range of element materials: copper, steel, stainless steel, cast iron, titanium, PFA-coated
  • Suitable for Tank Pneumatic Testing, Tank Leak Testing, Tank Thickness Testing, and Fuel Tank Water Removal Units
  • Available in kilowatt ratings from 1 kW to 200 kW

Tubular Heaters

Tubular direct immersion heaters are designed for direct heating of water, oils, solvents, viscous liquids, and gases. Heat is generated within the fluid for optimal efficiency, making them ideal for petrol filtration service, diesel filtration service, and fuel unloading filter applications.

Key Features:

  • Easy to install in tanks or pressurized vessels
  • Precise process temperature control
  • Mounting options include threaded screw plugs, flanges, or over-the-side designs

Flanged Immersion Heaters

Flanged immersion heaters use tubular or cartridge elements inserted in seamless pipes welded to the flange. This design allows easy replacement of elements without draining the tank, making them ideal for Chemical Tank Cleaning, Non Man Entry Tank Cleaning, and Diesel Tank Cleaning Robots.

Advantages:

  • Optimal watt density for long life
  • Even heat distribution prevents hot spots
  • Customizable temperature control and safety features
  • Efficient for tanks holding viscous substances like HFO, asphalt, and tar

Suction / Outflow Heaters

Suction heaters are designed to heat viscous liquids while pumping from storage tanks. These heaters are essential for Fuel Oil Tank Cleaning Companies, Underground Diesel Tank Cleaning, and Underground Petrol Tank Cleaning.

Features:

  • Instant heating from cold start
  • Maintains material at pumpable temperature
  • Replaceable heating elements without draining the tank
  • Available from 3 kW to 200 kW, customizable for large tanks

Applications:

  • HFO / FO
  • Asphalt, Molasses, Tar
  • Other high-viscosity materials

Inline Heaters

Inline heaters heat fluids or gases as they flow through pipelines. These are suitable for Fuel Testing Kits, Tanker Sampling Equipment, Bottom Samplers, and Fuel Filtration Services.

Construction Types:

  • Tubular Elements
  • Cartridge / Open Bobbin Elements

Benefits:

  • High heat transfer efficiency
  • Low watt density ensures long life
  • Easy element replacement without dismantling
  • Custom designs for 3 kW to 500 kW

Applications:

  • Liquid heating in pipelines
  • Gas heating (e.g., Argon, Helium, Nitrogen)
  • Steam superheating and compensation for steam losses

HFO & Fuel Handling System Heaters

Tristar provides complete HFO Heater solutions:

  • Immersion heaters in storage tanks to maintain HFO temperature
  • Suction/Outflow heaters to make fuel flowable
  • Inline heaters to preheat fuel before burners
  • These heaters optimize energy efficiency for Fuel Tank Cleaning Services, Diesel Filtration Services, and Petrol Filtration Services.


    Ship & Air Heaters

    • Ship Heaters: Reduce viscosity of bunker oil for pumpable flow. Suitable for heating oil, jacket water, or other fluids when steam generators are off. DNV-certified heaters available.
    • Air Heaters: Used for maintaining air temperature, humidity control, drying paint, and motor windings. Custom-designed tubular heaters with fins for maximum heat transfer.

    Paint Drying Air Heaters

    Paint drying air heaters are specially designed to heat air in enclosed spaces for applications like drying paint, maintaining room temperature, and controlling humidity. These heaters can be used in ducts or as standalone units and feature tubular elements with fins to maximize heat transfer. Tristar custom-designs these heaters to meet your exact requirements with various mounting options, ensuring efficient performance in industrial settings.


    Flameproof / Explosion-Proof Heaters

    For hazardous areas, Tristar provides explosion-proof immersion, inline, and outflow heaters with certified terminal and junction boxes.

    Materials & Standards:

  • Construction: CS, SS 304, SS 316, SS321

  • Controls: Thermostats, RTD, Thermocouple, PID
  • Accessories:

  • Pressure gauge, Drain valve, Relief valve, Flow switch, Pump interlock relay, Low liquid cutoff.

  • Cartridge & Open Bobbin Heater Elements

    Cartridge Elements: Metal-sheathed with MgO for thermal conductivity, parallel coil design for uniform heating, replaceable without removing heater body.

    Open Bobbin Elements: Ideal for oil, wax, fats, bitumen. Low surface temperature prevents product degradation. Easy replacement, very low watt density ensures longer life. Open Bobbin Heaters are designed to provide a large heated area when inserted into a thermo well, making them ideal for heating liquids and semi-solids such as oil, wax, fats, and bitumen, which require low surface temperature to prevent product degradation. Key Features: Can be removed for repair or replacement without draining the tank, supporting Non Man Entry Tank Cleaning and Underground Tank Cleaning Robots operations. Elements and insulators are made from high-quality ceramics such as cordierite and steatite, offering excellent thermal, physical, and electrical properties. Very low watt density on casing pipes ensures long life of elements and prevents charring or coking of fluids. Available in Inline Vertical Heaters and Inline Horizontal Heaters configurations. Power ratings from 3 kW to 240 kW. Watt density: 1 W/cm² to 1.5 W/cm² (6.45 to 9.6 W/in²). Fully customizable to suit your specific application requirements.
