Spiral Heat Exchangers

Spiral heat exchangers are manufactured using two metal plates wound together leaving two parallel channels where fluids can flow in a counter-current direction. They offer excellent thermal approaches but are best suited for high fouling fluids like slurries or fluids containing fibrous material.

Unique and Reliable Design

Spiral Plate Heat Exchangers (SPHE), present in various applications for almost a century, have proven to be the most efficient and reliable solution for handling fluids containing fibers and suspended particles.

Self Cleaning

Single channel combined with turbulent flow allows self cleaning of the spiral heat exchanger. The removable covers that can be equiped with davits makes easy maintenance and inspection operations.

Energy Saving

Countercurrent flow circulation makes it ~ 4 times more efficient than traditional shell & tube heat exchanger.

Compact

Compact shape easy to install and operate.
