Free Flow plate heat exchangers | Sondex/Danfoss

Free Flow plate heat exchangers by Sondex/Danfoss are designed to handle challenging heat transfer applications involving fluids with high viscosity, particulate matter, or a tendency to cause fouling. These exchangers feature a unique plate design that allows for unrestricted flow paths, minimizing the risk of clogging and ensuring efficient heat transfer. Ideal for industries such as wastewater treatment, pulp and paper, and food processing, Free Flow plate heat exchangers offer reliable performance, easy maintenance, and energy efficiency. Their robust construction and innovative design make them a versatile solution for demanding thermal applications.

Description

Our SONDEX® Free Flow plate heat exchangers are excellent choices for applications that use media with particle-rich contents, fouling tendency, or high viscosity. We customize each Free Flow heat exchanger to suit your application and media type. The contact-free plate channels ensure an unimpeded flow and long intervals between cleaning.

We set the new standard for improved performance and reliability when your media require gentle treatment and are unsuitable for regular heat exchangers due to viscosity, fouling tendency, or particle contents.

Features and benefits

  • Gentle treatment and even distribution of the media provide the highest possible product output quality.
  • High heat transfer efficiency and extended intervals between cleaning ensure operation for an entire campaign with minimum downtime and maximum value for money.
  • Large plate gap designed to counteract fouling with sizeable plate channels and no stagnant zones.

Applications

  • Dairy/food/beverage industry

         - e.g. food production, like juice and alcohol processing

  • Sugar industry

         - e.g. sugar production, such as concentration of sugar content in sugarcane juice
