Filter side
ACAF, OKAF, SCAF, OSCAF coolers are fitted with an oil-filter element.
Its contamination must be monitored. Please refer to the oil-filter

12. ACCESSORIES

On customer request, various accessories (e.g. AITR, AITF, AITF RS,
AITF RE, AITF SS, IBP/IBT, FU, GP, ESC, EL.BOX) can be mounted
on HYDAC coolers.
For further technical details and available accessories, for each cooler
type, please refer to our Accessories Catalogue, available on request.

13. STORAGE

HYDAC coolers must be stored in dry conditions (constant temperature
and constant humidity).
Fluctuations in temperature from cold to warm and vice versa must be
avoided. This may result in condensation and cause potential corrosion
problems.
When storing for less than one year, we recommend flushing inside the
cooling element with a suitable preserving fluid which is compatible with
aluminum (see §10). Take into account the intended operating fluid.
Always seal the ports.
When storing for more than one year, HYDAC recommends filling the
cooler with a preserving fluid and sealing the ports. The preserving fluid
(see §10) must be removed completely before using the cooler again.
If necessary use a suitable cleaning agent.
