Features of auxiliary heater products:
1. Reasonable structure: unique design, stable performance, safe and reliable; Large power capacity, moderate volume, easy installation and use.
2. High thermal efficiency: The heating tubes are arranged reasonably and generate heat evenly; Low surface temperature, capable of rapid heating.
3. Safe and energy-saving: There is an over temperature protection device inside the heating component. When the temperature inside the cylinder exceeds the limit, the control circuit can be cut off to ensure equipment safety; Can be connected to a temperature control device for convenient temperature adjustment, thereby achieving energy-saving effects.
4. Excellent performance: High quality electric heating tubes ensure that the electrical performance of the product far exceeds national standards, ensuring product safety, reliability, and long service life.

Structure and Application of Auxiliary Heater Products:
The auxiliary electric heater consists of stainless steel heating elements, inlet and outlet ports, mounting seat, temperature protector, junction box, and cylinder body (carbon steel or stainless steel); Can be equipped with control devices.
This series of products is widely used for supplementary heating of water systems in central air conditioning units. When the temperature of the water medium is too low and the host is difficult to start, the water medium is preheated to raise the water temperature to meet the requirements of use, ensuring the normal start and operation of the unit, improving heating efficiency and effectiveness, and extending the service life of the air conditioning unit. It can also be used in hot water supply systems and other occasions that require heating. The main types are vertical and horizontal, and special specifications can be designed and manufactured according to user requirements.

Usage, maintenance, and precautions:
1. Work pressure: not exceeding 1.1 times the rated value, and the casing should be effectively grounded.
2. Working medium: Clean flowing water that is not easily scaled, non corrosive, and free of impurities.
3. Before use, the water valve should be opened first to ensure that the cylinder is filled with water medium and the pressure is not greater than the working pressure before electric heating can be applied.
4. During use, the system should maintain sufficient water pressure to ensure that all electric heating tubes are immersed in flowing water, in order to prevent dry burning due to water shortage and damage to the electric heating tubes.
5. When not in use in winter, drain the remaining water in the cylinder to avoid freezing and damaging it.
6. When not in use for a long time, the power and water sources should be turned off, and any remaining water in the cylinder should be drained.
