Features and Advantages
- Circulation pump with stainless steel magnetic drive ensures no leakage at high temperatures.
- Expansion tank made of SUS304 material, offering strong corrosion resistance.
- All pipes in the circulation system are made of SUS304 stainless steel.
- Sealed circulation system prevents the thermal fluid from evaporating and oxidizing easily, extending the service life of the thermal fluid and avoiding environmental pollution.
- Casters with brake devices facilitate easy movement and precise positioning of the equipment.
- Temperature control utilizes PID algorithm for high precision.
- Button input and LCD display ensure easy operation.
- Equipped with a liquid level display tube to monitor the amount of thermal fluid in the system in real-time, ensuring safe usage.
- Over-temperature protection device cuts off power and alarms immediately when the system temperature exceeds the set limit, ensuring safety.
- Comes with cooling coils that can be connected to an external cooling water source to adjust the temperature of the thermal fluid, meeting process requirements.
- Features RS485 communication function.
