High-Temperature Process Control for Demanding Industrial Applications

Heavy Duty Hot Oil Temperature Units provide controlled heating and circulation of thermal oil for industrial processes requiring elevated and stable operating temperatures. The system transfers heat through a closed thermal oil loop between the unit and process equipment.

Typical applications include large injection molds, die casting, rubber processing, chemical reactors, rollers, calendering equipment, and composite tooling.

Key Technical Specifications

When selecting a unit, evaluate complete operating conditions rather than the maximum temperature alone.

Specification Category	Parameter Details
Max Operating Temperature	Up to 200 C, 300 C, or 350 C (Custom classes available)
Heating Capacity	Ranging from 15 kW to over 150 kW based on thermal load
Oil Circulation Flow	Sized according to process heat transfer requirements
Pump Pressure	Engineered to overcome total loop resistance
Cooling Capacity	Optional integrated heat exchangers for controlled cool-down
Electrical Standards	CE (Europe), UL/CSA (North America), ISO compliant

Core Performance Factors

Heating Capacity
Determines how quickly the system heats equipment and compensates for continuous production heat losses. Selection depends on mold/vessel mass, process material, target temperature, and heat-up time.

Oil Circulation Flow & Pump Pressure
Flow and pressure must be evaluated together. The pump must deliver sufficient flow against the actual pressure resistance of the complete circulation loop (pipes, valves, bends, and process equipment) rather than relying on max rated flow alone.

Thermal Fluid Compatibility
The unit and thermal oil operate as a single system. Fluid selection must match the operating temperature, thermal stability, viscosity, and flash point specified by the oil manufacturer.

Rollers & Calendering: Offers high circulation capacity to maintain uniform surface temperatures.

Composite Processing: Tailored for heated composite tooling and high-temperature curing.

Quality Control & Global Support

Factory Testing: Every unit undergoes rigorous pre-shipment testing, including heating verification, oil circulation checks, PID control testing, and full leak testing.

Global Support: Backed by fast-dispatch spare parts (pumps, heaters, valves), remote engineering diagnostics, and complete English technical documentation.

FAQ

Q: What is a Heavy Duty Hot Oil Temperature Unit?

A: It is an industrial thermal control system that heats and circulates thermal oil to maintain stable, elevated operating temperatures in process equipment.

Q: How do I determine the required heating capacity?

A: Calculation is based on equipment mass, process material, starting versus target temperatures, required heat-up time, and continuous production heat losses.

Q: Why must oil flow and pump pressure be evaluated together?

A: The pump must overcome the pressure resistance of the entire closed loop (pipes, valves, and process channels) while still delivering the required flow rate for effective heat transfer.

Q: Can the unit provide both heating and cooling?

A: Yes. Integrated cooling options can be configured for processes that require controlled temperature reduction or dissipation of reaction heat.

Q: What information is needed to request an accurate quotation?

A: Provide your application type, operating temperature, heating load, thermal oil type, required flow/pressure, power supply specifications, and process connection sizes.
