Currently, most factories require heating during the production of their products and materials. Yet, many of these companies' customers remain unclear about whether electric heating thermal oil mold temperature controllers or steam boilers offer greater advantages. To help clarify this, Ouno’s editor will now provide an analysis. First, let’s explore the key features of steam boilers. A steam boiler operates through a dedicated boiler system. High-pressure pumps deliver appropriately heated heat transfer fluid—usually water—to the boiler system. The heat generated by the combustion process is transferred directly into the boiler body, where it heats the water circulating inside the heat exchange pipes. This results in the production of high-pressure steam, which is then routed through pipelines to heat exchange equipment. There, the steam transfers its heat to the oil that needs deodorization before returning to the system.

Currently, most factories need to heat their products and materials during the manufacturing process. Yet, many of these companies' customers remain unclear about whether electric heating thermal oil mold temperature controllers or steam boilers offer greater advantages. So, let’s dive into an analysis provided by Ouno’s editor to help clarify the situation.
 
First, let’s take a look at the key features of steam boilers. A steam boiler operates through a boiler system: appropriately treated heat-transfer water is pumped into the system under high pressure by a high-pressure pump. The heat generated by the combustion system then enters the boiler body itself, where it transfers its energy to the water flowing through the heat-exchange pipes, producing high-pressure steam. This steam is routed via pipelines to heat-exchange equipment, where it comes into contact with the oil requiring deodorization. After heat exchange, the condensed water flows back through pipes directly into the boiler system, restarting the continuous cycle of evaporation, heat transfer, and condensation.
 
During operation, the control system automatically manages parameters such as temperature and pressure based on the pre-entered data, ensuring the system runs safely within its designated limits. The boiler system is also equipped with multiple layers of safety protection—both in terms of software and mechanical design. If the system detects abnormal conditions like overpressure, the control system will automatically shut down the burner. Additionally, when the system pressure exceeds the preset threshold of the safety valve, the safety mechanism will activate to prevent further risks.
 
Steam boiler piping systems lose a significant amount of heat, and in addition to the high operating temperatures, another reason steam boilers are less efficient for heating compared to electrically heated thermal oil mold temperature controllers is the failure to promptly repair or maintain damaged insulation. Moreover, steam boiler systems often suffer from severe leaks—yet for the same leak area, steam carries away far more heat than water does. Beyond being uneconomical, steam-based heating is also unsafe, as it poses risks of scalding injuries and potentially leads to water hammer explosions that can rupture pipes. Many steam boiler systems even experience noticeable vibrations and water hammer noises during operation, disrupting both work and rest. Additionally, steam heating tends to dry out the air in the room, making occupants feel uncomfortable.
