When your media require gentle treatment and are unsuitable for regular heat exchangers due to viscosity, fouling tendency, or particle contents, SONDEX® Free Flow sets the new standard for improved performance and reliability.
What does that mean for you?
Experience the benefit of maximum uptime with SONDEX® Free Flow plate heat exchangers. The contact-free plate channels lower the risk of fouling and clogging and ensure extended operation.
Prolonged production time and loss of product on account of frequent, unscheduled maintenance or cleaning, is an undesirable consequence of operating with hard-to-treat media.
Our engineers have designed the SONDEX® Free Flow solutions to reliably deliver the highest performance and gentle media treatment, while keeping the intervals between service as long as possible. If your media contains solids, fibers or other particles, the service intervals can be extended even further by regularly back-flushing the system.
Easy cleaning, maximum uptime
For media with fouling tendencies, CIP (Cleaning In Place) is the preferred option. The efficient design of the SONDEX® Free Flow ensures a low hold-up volume, which minimizes the amount of chemicals needed for the CIP process, and thus greatly reduces cleaning time, while also being environmentally friendly.
