Product Details

Double Circuit Copper Tubular Heat Exchanger Evaporator For Screw Chiller Refrigeration

This company's refrigeration shell and tube heat exchanger, from the choice of heat exchanger

performance, diameter size, structure, arrangement, to determine the combination of tube form, and the

use of new sealing materials and sealing methods, carried out more Aspects of optimization design,

comprehensive technical performance in the domestic advanced level.

1, after accurate matching check, heat transfer calculation, integrated optimization design, high heat

transfer efficiency.

2, with dense and enhanced technology, small size, large heat transfer area, good heat transfer

performance.

3, heat exchanger selection of high quality and efficient reinforcement of copper, heat pipe and tube plate

connection using pure mechanical expansion, reliable quality.

4, the use of high-performance, long-life sealing material and high-strength sealing structure, good

sealing
