Professional heat exchanger factory with 20 years of experience, providing you with one-stop heat transfer solutions to design different heat exchangers according to your purposes (metallurgy, food, petrochemical, pharmaceutical, beverage, wastewater, refrigeration, etc...)
Dellok Young is a professional manufacturer of various heat exchangers integrating R&D, design, production and sales. The heat exchangers produced are mainly used in petrochemical, electric power, papermaking, building heating, mining and other industries, such as air heaters, food industry plant protein powder, starch and other air heater spray drying systems.
The company now has a professional technical innovation team and professional after-sales personnel. The company's production plant covers an area of approximately 18,000 square meters, has multiple professional and advanced CNC and automated production equipment, and has obtained a number of professional certificates and patents.
The company has a professional foreign trade team and has trade cooperation with various regions. Some global partners conducted on-site inspections of the production plants and were very satisfied with the inspection results and established long-term strategic cooperative relationships with our company.
Product Description
Low Fin Integral Low is a particular working on the tube by direct extrusion, that increase the surface, and improve the thermical performance of the heat exchanger without changing or increase the shell size. Integral Low Fin is supplied straight and/or U tubes bended as Thelma R, annealed in U Bent zone, and hydro-tested after bending. We also can supply fin tubes with skipped fin sections in the baffle points where there is the possibilities of vibrations in the heat exchanger.
Manufacturing Process:
The Tube and Fin are in same material. After rolling process, the outer surface of tube is formed with thread, which makes the finned tube have a higher heat transfer capacity.
Integral Low Finned Tube Advantages:
Increased surface area for heat transfer, smaller heat exchanger, less number of heat exchangers, reduced equipment and installation cost, debottlenecking existing heat exchangers, upgrading to corrosion resistant alloys without sacrificing heat transfer efficiency, and reduced fouling (in some cases).

FAQ
1. How do you control your quality?
We always put quality as the most important thing for customers, and we control the quality from raw material inspection, production checking to water pressure test and strength test. Also the third party can be authorized to check.Incoming inspection report for bare tube & strip.
2. What are low finned tubes?
Low Finned tube is a finned tube obtained through plastic cold deformation. The method consists in realizing, from a smooth tube, fins with a particular geometric form without removing material; this plastic deformation causes an increment of heat exchange efficiency, and allows to reduce the heat exchanger size.
