In the cold winter,when the central air-conditioning unit work, the heat lose one part through the pipeline evaporation. Compressor work at high-pressure condition, the volumetric efficiency and indicated efficiency of compressor must decline, resulting in the heat pump heating capacity and heating effects will decline. Generally in this condition, people will use auxiliary heating equipment. In the past, people used to install a small boiler to add heat energy.
Boiler assist heating, although get some effect on reinforce the heat energy,cause it covers a large area, has a certain impact on the environment, costs a lot manpower, in the nowadays of pursuit energy-saving, environment protection, efficiency,it's not the best choice, central air-conditioning just make up for this deficiency.
Auxiliary electrical heater has the following advantages, it covers a small area, and it has a obviously advantage in fix, operate, environment and manpower than boiler heater and other heating equipment.
Auxiliary electrical heater after installation, with central air-conditioning system into a combination of the overall. Before central air-conditioning system works, we can heat the recycle water in advance to increase the temperature of water. Before air-conditioning systems working and running, increase the air-conditioning systems heating effects and work efficiency, so as to achieve air-conditioning system optimum efficiency when it works.

Features:
1. The overall use of stainless steel structure, small size, less space covers, convenient for moved, water-proof design, and with strong corrosion resistance, it is filled with high-quality insulation materials between the stainless steel inner and outer, it can keep constant temperature with a long time and save electric energy. 

2. The internal electric heating tubes of the main components used imported materials, processing is also used in the course of advanced production equipment and techniques, its insulation function, voltage function, moisture-proof properties are better than national standards, it is safe and reliable, and it passed two test with quality inspection department and bureau of mechanical engineering in Jiangsu.

3. The flow direction is rational, uniform heating, non-high and low-temperature corner, with hot and high efficiency.

4. Auxiliary electrical heater installed a well-known brands of thermostats , it can control water temperature and avoid damage for the system components.

5. It is convient for repair and maintenance, you can only remove the sealing cover and take off the screw nut on the ring flange, and then electric heating tubes can be extracted.

6. The electric control box can be equiped with customer requirements, the components are use of well-known brands of DELIXI, with safe and reliable.

7. The auxiliary heaters are designed according to customer requirements, and using the polarization control heating subsector.
