Spiral Heat Exchanger

The perfect solution when plate and tubular heat exchangers are not sufficient for dirty media!!

Design:

Sondex spiral heat exchanger is a circular heat exchanger with two spiral channels, each in one closed chamber ensuring that what comes in also comes out.
The flow of the two products is countercurrent, which makes it possible to have a close temperature approach between the two media being treated in the heat exchanger.
In the same spiral heat exchanger the design makes it possible to run free flow in the one side and standard flow on the other side.

Media and Applications:

A large variety of fluids can be suitable for a spiral heat exchanger solution e.g. fouling liquids containing solids and fibers, wastewater slurries mixtures with invert gases, cooling and heat recovery, vapour/liquid condenser, vacuum condenser with inert gases.

Easy access to the heat transmission area:

It is essential to have easy access to the heat transmission area for maintenance, with a Sondex spiral heat exchanger this is a very easy task. Each side of the closed spirals can be accessed by opening the side frame of the heat exchanger, without any use of special tools. When opening the side frame there will be fully access to the heat transmission area on one side. This side can be cleaned without getting in contact with the other side of the heat exchanger. The side frame is designed with hinges making lifting equipment unnecessary.

A very flexible pipe fitting solution:

As an extra feature the flexible pipe connections make it possible to run CIP cleaning through the installation, when required.

Long life gasket solution:

The two gaskets placed on the side frame are ensuring a long-lasting solution. The opening and closing of the side frame increases wear of the gasket. Therefore the Sondex solution does not only have one gasket covering the hole side frame, but an edge gasket which can be easily replaced when wear occurs.

Customized solutions:

No application and duties are the same for a spiral heat exchanger meaning that all Sondex spiral heat exchangers are always customized according to the specification from the customer.

Saving valuable production area:

The spiral heat exchangers are a very compact solution. The design requires only small space for installation compared to traditional heat exchanger solutions. This saves valuable production space and costs.
