Product Design

Our brazed heat exchanger designs are by Unilab heat transfer software. With the SELECTION mode, you can input specific parameters like capacity, maximum pressure drops, and the desired number of passes. The software then employs calculations to determine the optimal plate geometry and the required number of plates for achieving optimal heat performance.

The selection of a suitable heat exchanger is crucial,we can accurately determine the type of heat exchanger that best suits your needs.Our heat exchangers are constructed using high-quality materials.   

The plates are made of stainless steel 316 or 304, while the brazing material can be copper or nickel.   This ensures the durability and reliability of our heat exchangers, making them suitable for a wide range of applications.

Product Advantage

1.The brazed heat exchanger exhibits exceptional heat transfer performance, ensuring efficient and rapid heat exchange between fluids.

2.It is designed to operate reliably even under high temperature and pressure conditions, making it suitable for demanding applications.

3.The brazed heat exchanger features a robust gasket-less brazed structure that ensures a tight and reliable seal, preventing any leakage or cross-contamination between the fluids.

4.With its compact and lightweight design, the heat exchanger utilizes thinner materials, resulting in a space-saving solution that doesn't compromise on strength and durability.
