NEW Shell & Tube Heat Exchanger

Shell & tube heat exchanger


Shenshi's 130KW shell and tube are used for evaporators and condensers of hot and cold water units, modular units and other units; 7mm heat transfer tube upgrade, spiral baffle optimization, and multiple Shenshi's patented distributors are used in combination, with high heat exchange efficiency ; Shenshi's shell tube is designed and manufactured strictly in accordance with GB150, 151 standards. The fluorine side head is laser welded, with high pressure, no risk of leakage from traditional gaskets, the heat exchange tube is integrally formed, no splicing, no solder joints and water Contact, freeze resistance and strong reliability; Patented optimized design of the fluorine side head saves material costs, small housing for small heat transfer tubes, high compactness, and small material consumption.

Features


①. High heat exchange efficiency                                                 ⑤. Laser welding for more sealing
②. 7mm heat transfer tube                                                            ⑥. Integrated molding without splicing
③. Spiral baffle                                                                               ⑦. Strong frost resistance
④. Patent dispenser                                                                       ⑧. Excellent value for money

Efficient Design


Shenshi's design heat transfer tube: 7mm heat transfer tube, bottom wall thickness 0.35mm, number of teeth, tooth height and helix angle are all own parameters, the result of repeated optimization.


Shenshi's spiral baffle: unique lock design, tight stitching in the splicing area, smooth and natural transition, uniform flow velocity on the water side, high heat exchange efficiency; no dead zone, reducing freezing risks.


Shenshi's patent distributor: Refrigeration: 1 mix + 2 distributions Heat pump: 1 mix + 1 distribution.
