Heat exchangers

Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions supplied with the product.

Installation note:

The installation depends on the application and on the service required; however the unit must always be installed horizontally.

It is always necessary that one end of the heat exchanger is allowed to move axially, in order to permit the normal expansion of the

exchangers tubes during operation.

We recommend that an air vent be fitted to the unit to continuously vent during start-up and operation.

Insulation is recommended, and it is absolutely necessary, if the shell temperature is much higher than the ambient one - If insulation is

required it is suggested that it be fitted on site to eradicate its damage whist in transit.
