Frequently Asked Questions

Q: What are the main advantages of thermal oil boilers over steam boilers?

Thermal oil boilers can achieve higher temperatures at much lower pressures, reducing safety risks and eliminating the need for expensive high-pressure vessels and intensive water treatment.

Q: How does the closed-loop system improve efficiency?

The closed-loop system prevents the loss of the heating medium and minimizes heat dissipation to the environment, ensuring that maximum thermal energy is delivered to the application point.

Q: Is it possible to replace an existing steam boiler with a thermal oil boiler?

Yes, especially in water-poor regions. Since oil acts as the heat carrier, you can replace water-dependent steam systems with our thermal oil solutions for more stable heating.

Q: What is the maximum design temperature for these boilers?

Our gas fired thermal oil boilers are designed to operate safely at a maximum design working temperature of up to 320℃.

Q: What safety features are included in the control system?

The system includes comprehensive safety detection devices, including over-temperature protection, pressure limits, and automated shutdown sequences to ensure operational safety.

Q: How do I choose the right model based on thermal power?

Selection depends on your total heat load requirement. We offer a wide range from 350Kw (YQW-350) up to 4000Kw (YQW-4000) to match various industrial scales.
