1. Standard electrical protection is available, including flow and short-circuit protection.

2. There is an independent over-temperature alarm system separate from the temperature control. When the internal temperature of the electric heater exceeds the set value, it will shut down the electric heater without automatic reset and output a contact signal.

3. A separate low-level alarm system is in place. It automatically shuts off the electric heater when the liquid level falls below the required threshold and sends out a signal.

4. Offer multiple interlocking interfaces for connection with other equipment such as pumps, flow (pressure) switches, etc., to ensure that there is a certain flow of medium while the heater is heating, guaranteeing the safety of the system.

5. Control can be directed to:DCSThe system provides status updates for the heating system, including running, stopped, over-temperature alarm, level signal (low level alarm), interlock status, and temperature signal.4~20mA) Such signals, excluding temperature signals, are all passive contacts; capable of acceptingDCSThe start and stop operation commands issued, along with the required contact capacity, are also220V   1A。

6. AvailablePIDTemperature control feature: The heating system can be programmed to set the temperature rise curve of the medium, and it can control the pump according to process requirements in case of insufficient flow or after heating stops. This control system employs multi-level control technology, dividing the heater into several groups. One group, the larger one, can adjust pressure continuously. Based on the outlet temperature and after calculation, the control system automatically controls the on/off of each heater group and the output power of another heater group, achieving continuous power adjustment. This effectively improves the accuracy of temperature control.

1. Three-dimensional electric heating is for small and medium-sized enterprises.

2. Holds nine patents, including the patent number for the molten salt槽 electric heater.ZL 2013 2****Please consult our company for detailed item numbers:18012823108）；
