Electrically heated hot water boiler introduction
This product is a horizontal fully automatic electric heating hot water boiler. It features a separate electric control cabinet from the boiler body, which prevents electrical components from overheating and aging, thereby extending the service life. The electric heating tubes are selected from both domestic and international products, with an average service life of about 20,000 hours and a thermal efficiency of nearly 99%. The operation is quiet and clean, meeting environmental protection requirements and not emitting NOx (nitrogen oxides) into the atmosphere. It runs on a PLC control system, featuring no operation buttons, no indicator lights, a touch screen panel, both Chinese and English display, human-machine dialogue, operation authorization, real-time information, and automatic page turning.
All electrical components are CE and CCC certified to ensure product safety and longevity. Each heating element is connected using a centralized flange, independently set up, featuring simple structure, high mechanical strength, safety, reliability, easy replacement, and long service life. Separate mechanical and electrical installation, with electrical control components away from heat sources for better heat dissipation. Can be used individually or in parallel. PLC microcomputer programmable control and display screen; temperature setting and automatic control of water outlet temperature are achieved through a human-machine interface. The display screen can show equipment status, operating parameters, and fault alarms.
Advantages and Features of Electrically Heated Hot Water Boilers
1. Silent, pollution-free, with high thermal efficiency, the boiler body is insulated with thermal insulation material, minimizing heat loss and promoting energy conservation and cost reduction.
2. The boiler's outer packaging is designed with high-quality color steel sheet, featuring an aesthetically pleasing and generous appearance, and is resistant to rust.
3. All electrical components come with CE and CCC certification marks to ensure product safety and longevity.
4. Circuit design, meticulously crafted with neat and logical wiring, offers exceptional ease of operation.
5. Electric heating tubes are connected to the furnace body with flanges, allowing for easy assembly and disassembly, and facilitating maintenance and care.
6. Equipped with safety protection systems including automatic water refilling, water shortage, over-temperature, over-pressure, automatic power cutoff with alarm, and electric leakage protection.
7. PLC microcomputer programmable control and display screen; automatic control of water outlet temperature through a human-machine interface, with the display screen showing equipment status, operating parameters, and fault alarms.
