Product Introduction
The CWDR series fully automatic electric heating hot water boiler with four-way boiler adopts PLC (Programmable Logic Controller) control, with a novel design and compact structure. Through a new arrangement and combination of electric heating elements, it achieves efficient energy conversion and provides high-quality hot water.
This product belongs to a horizontal fully automatic electric heating hot water boiler, which adopts a separation method of furnace body electric control cabinet, avoiding the aging of electrical components caused by heat and affecting their service life. The electric heating tube is made of high-quality products from both domestic and foreign sources, with a normal service life of about 20000 hours and a thermal efficiency of nearly 99%. It operates quietly and cleanly, meeting environmental protection requirements. It is a truly green, environmentally friendly, and energy-saving product that does not emit NOx (nitrogen oxides) into the atmosphere.
CWDR electric heating hot water boilers currently have over 20 conventional specifications, with rated thermal power ranging from 0.35 to 2.8 MW and a designed thermal efficiency of ≥ 98%. Boilers can be designed in modular combinations according to different user requirements, or individually designed for user needs.
Performance advantages
(1) Horizontal quick installation electric heating hot water boiler, with electric heating tubes arranged at both ends, with advanced and reasonable structure. And operate with full water to ensure that the heat generated by the electric heating tube can be conducted in a timely manner, allowing it to receive sufficient cooling, thereby extending its lifespan and improving the thermal efficiency of the boiler; It can also effectively reduce hot water carryover and improve the quality of exported hot water.
(2) It has automatic alarm and multiple interlocking protection functions for high and low water levels, water shortage, overcurrent, short circuit, phase loss, leakage, etc., ensuring safe and reliable operation.
(3) Using high-quality electric heating elements, with low surface load, good heat transfer effect, and long service life.
(4) Electric heating elements automatically add or subtract based on the set load parameters to achieve balanced operation.
(5) PLC fully automatic control: It can achieve automatic pressure regulation, automatic water replenishment, timed automatic start stop, and manual emergency operation, making it convenient and reliable to use.
(6) Compact structure, small size, and small footprint, it can operate as a single unit or be used in combination with multiple units.
(7) Advanced technology, excellent material selection, reliable quality, and long service life.
