A spiral wound heat exchanger is an efficient and compact heat transfer device, featuring a core structure of spirally wound tube bundles enclosed in a shell. Two fluids flow through the tube side and shell side respectively, transferring heat through the tube walls. With a compact design, high heat transfer efficiency, and adaptability to high-pressure, low-temperature, and other complex conditions, it is widely used in chemical, petrochemical, LNG, refrigeration, and waste heat recovery fields.

Titanium spiral wound heat exchanger is a corrosion-resistant and efficient heat transfer device, designed for severe corrosion, high-temperature and high-pressure scenarios. It uses titanium spiral tubes and special flow channels for high heat transfer efficiency, adapting to extreme temperature differences and being durable. With strong corrosion resistance, titanium makes it ideal for chemical, seawater treatment and other corrosive environments. The equipment is small in size, light in weight, reduces scaling, and is easier to maintain.

The dichloromethane condenser, specialized for condensing dichloromethane vapor, is widely used in chemical synthesis, pharmaceutical purification, solvent recovery, and related distillation/tail gas treatment processes.

Given dichloromethane's low boiling point (≈39.8℃), volatility, and mild corrosiveness, it's typically made of 304/316 stainless steel, with spiral wound or shell-and-tube structures for compact, efficient heat exchange. It uses coolants like cooling water to condense vapor below its boiling point via counter-flow heat exchange, achieving over 95% efficiency.

Featuring tight sealing and pressure monitoring to prevent toxic, flammable leaks, it reduces energy use and aids solvent recycling and emission reduction.
