Model series SWF / SWP and SSWF / SSWP — three-chamber devices with a monitored barrier space, so the two operating media cannot mix.
Figures describe the model series as a whole. Size, material and arrangement are fixed at selection, against the duty you send us.
In each individual internal tube of the bundle a further, smaller internal tube is installed. These concentric tube pairs form radial gaps, interconnected by the design of the double tubesheets, and together they produce an enclosed safety space.
That sealed space is filled with a special barrier fluid and checked for pressure changes by a pressure control device. A mixing of the flowing operating media is prevented in this way.
To stop thermal expansion of the barrier fluid from raising the pressure and causing a false alarm, the safety space is additionally fitted with compensation.
Environmental protection — for example where cooling water is drawn from surface waters.
Health protection — where a reaction between the two operating media must be excluded.
Cost of operating resources — where disposal of a contaminated fluid and refilling would be expensive.
Documents are published by the manufacturer, so these links always give you the current revision.
Material selection for standard safety exchangers in sizes 300 to 808 follows the BCF/P, CCF/P and SSCF/P description. Materials for devices from size 1003 change according to the manufacturer’s own table and are confirmed per order.

Source of technical data. Construction, barrier space, selection criteria and size boundaries come from the Funke shell-and-tube heat exchanger product information, model series SWF/P and SSWF/P.
