What is the maximum pressure of a thermal oil heater?
The circulating pressure of a thermal oil boiler is generated by the driving of the circulating oil pump to the thermal oil circulation. Generally, the working pressure of the thermal oil pump is 4 ~ 8kg / cm2. Actually, the pressure of the thermal oil pump differs from different working conditions.
What are the factors that affect the maximum pressure of thermal oil heater?
1. Pressure of circulating hot oil pump
The pressure of liquid phase thermal oil heater and heating system is determined by the pressure of circulating pump, so the heating mode of thermal oil heater system is forced circulation of liquid phase, and circulating pump plays a "heart" role in the circulation of thermal oil in the whole heating system. If the circulation pump stops running, the circulation of thermal oil will be interrupted.
2. Diameter of oil inlet and outlet
If the inlet and outlet diameter of the oil pump is larger, the pressure of the heat transfer oil will be larger and the oil speed of the thermal oil will be faster, thus ensuring that the thermal oil heater can have a good temperature control effect.
The high working pressure of heat conduction oil furnace indicates that the flow rate of thermal oil in the system is fast. The thermal oil heater should have a large flow rate and a fast flow rate, so that the better the temperature control effect. In the design of heat conduction oil furnace, it is necessary to consider the high-temperature resistance of flanges, valves, pipes, circulating pumps and other components to prevent heat transfer oil from leaking at high temperature.

In industries such as chemicals, plastic packaging, new materials, and building materials, thermal energy supply is closely related not only to production continuity, but also to product quality and operating costs. As companies place higher requirements on process temperature control, fuel adaptability, and system stability, thermal oil boilers are becoming an important heat source in many industrial applications. Based on different fuel conditions and production needs, ZOZEN Boiler continues t...02 Jun 2026 -
Packaging connects production with consumption. A carton, a piece of corrugated board, or a roll of plastic film may look light and simple, but behind each of them is a stable, continuous, and process-matched thermal energy system. As demand continues to grow in food packaging, industrial packaging, e-commerce packaging, and plastic packaging, the packaging industry is placing more specific requirements on boiler equipment: stable steam supply, fuel adaptability, process temperature control, ope...26 May 2026
