Free Flow plates

SONDEX® Free Flow plate

What does that mean for you?

The deep and wide channels provide ample room for hard-to-handle media to flow effortlessly, ensuring gentle treatment of the output product and leading to sustainable quality improvements.

Since there is only line contact between the plates, even long and sticky particles will not get stuck and clog the heat exchanger.

The Free Flow plates are also well-suited for media that tend to cause fouling, and are designed with the fouling factor in mind. The channels allow for efficient heat transfer and an ideal flow regardless of the accumulated fouling. Because of this, cleaning can be postponed and you achieve longer operational uptime.

This enables a sugar producer, for example, to operate at full capacity throughout an entire campaign without losing valuable production time and product output.

Features and benefits

Ensures an unimpeded flow due to the deep channels and limited contact points between the plates. The large plate gap is designed to handle media that cause fouling and clog regular heat exchangers.
Extended operation time, with no cleaning needed, regardless of the media’s viscosity, fouling tendency, and particle contents.
Asymmetric patterns are available for applications with big flow rate differences. Taking the flow rate differences into account eliminates problems with air pockets, media maldistribution and low turbulence.

SONDEX® Free Flow

SONDEX^® Free Flow plates feature deep and wide channels that provide enough room for media that contain fibers and particles, or high-viscosity media. The channels allow for efficient heat transfer and an ideal flow.
