Technical Edges

1.Superior Heat Transfer Performance: The advanced corrugated (twisted) tube design significantly enhances turbulence within the fluid, resulting in outstanding heat transfer efficiency. Compared to conventional straight titanium tubes of the same diameter, wall thickness, and length, thermal performance is improved by 1.3 to 2.6 times, enabling faster and more energy-efficient temperature control.

2.Exceptional Corrosion Resistance & Reliability: Manufactured using Grade 1 titanium in compliance with GB/T 3625-1995 standards, these heat exchangers are engineered for the most demanding environments. Each unit undergoes rigorous quality testing, including:

a.High-pressure testing up to 43 bar

b.Precision halogen leak detection

c.100,000-cycle fatigue testing at 4.5 bar

d.This ensures long-term durability, zero leakage, and reliable operation even in highly corrosive media such as seawater, acids, and alkaline solutions.

3.Enhanced Anti-Scaling & Low Maintenance Design: The seamless, weld-free corrugated tube construction minimizes weak points and significantly reduces the risk of leakage. The induced turbulent flow effectively inhibits scale formation and fouling, leading to:

a.Extended service life

b.Consistent thermal efficiency

c.Reduced maintenance and operational costs

4.Robust and Corrosion-Resistant Shell Construction: The outer shell is manufactured using high-grade PVC, offering excellent resistance to acids, alkalis, and corrosive environments. Designed to withstand operational pressure while maintaining structural integrity, the unit is also RoHS compliant, ensuring environmental safety and sustainability.

5.Compact, Lightweight & Installation-Friendly Design: With a sleek and compact structure, the heat exchanger delivers high performance without occupying excessive space. Its lightweight construction, combined with strong strain compensation capability, allows for easy handling and installation across a wide range of applications.
