SONDEX® traditional plate heat exchangers are the go-to choice for standard duties. The versatile design and high thermal efficiency make them the perfect solution for a wide range of applications.
Our extensive plate portfolio and pattern options ensure that we always have a solution that is exactly right for you. Our patterns create the ideal turbulent flow and make the best use of the available pressure drop for any duty.
Always the efficient choice
We design single-pass solutions when possible, as they are the preferred choice for almost all duties. With all connections on the head, you do not need to disconnect the heat exchanger from the piping to perform inspection, cleaning, or service. Go with a SONDEX® heat exchanger for simple, fast, and easy installation and maintenance.
With minimal space requirements, considerably lower energy consumption, and reduced number of plates needed for optimal performance, SONDEX® heat exchangers are designed with tomorrow in mind.
