CWDR Series Electric Hot Water Boiler
CWNS series boiler is full automatic electric hot water boiler, it use PLC control system, the electric heating elements are rearranged and recombined, the boiler has compact structure and high thermal efficiency (99%). The boiler body and electric control cabient are separate, to avoid the influence of thermal aging on electrical components. The boiler operate quietly, and no NOx emission, it is the real green environmental protection energy-saving product.
Zhongding electric hot water boiler is generally used for central heating and hot water supplying in hotel, gym, school, hospital.

Boilers Structure
1. The boiler adopts stainless stell electric heating tubes, the thermal efficiency is high. No harmful gas emission, environmental friendly.
2. All the electrical components ahve CE and CCC cerfication, to gaurantee the safety operation and long working life. Each group electrical heating elements are connected by clustered flanges, has simple structure and high mechanical strength. The boiler uses high quality cartridge heater, could working for more than 20000 hours.
3. The boiler is equipped with reliable auxiliaries and multiple safety protection device, such as pressure controller, presure transmitter, water level alarm, and safety valves, etc.
4. The boiler adopts full automatic interlock protection program, has the protection function of water shortage, over pressure, over temperature, flame out, electric leakage, and phrase-lacking or over-loading of motor, etc.
Auxiliary equipment
CARTIDGE HEATERS
The boiler adopts high quality cartidge heaters with CE and CCC certificates, could used for more than 20000 hours.
CONTROL SYSTEM
We adopt Siemens PLC and Schneider electrical components. can realize automatic interlock control to ensure boiler safe operate.
INSULATING LAYER
The boiler uses aluminium silicate board for heat preservation, has high thermal shielding efficiency and low heat loss.
WATER PUMP
We adopts the stainless vertical pump with low noise, stainless impeller and pump body.
Steam header
Standard configuration: one inlet, three outlets, equipped with pressure gauge and thermometer. It can be designed according to customers' requirement.
Water softener
It is fully automatic and free debugging. We adopts PE material for salt tank body, it has hard texture and it is easy to move, anti-shock, and no leakage.
Quality
Zhongding Boiler pay more attention to the boiler quality from raw material to producing process.
