4.5 HYDRAULIC CONNECTIONS AND SPECIFICATIONS OF THE COOLER
For the hydraulic connection points see the dimensional drawings and the labels on the product.
Use water charged with 10% ethylene glycol and with anti-corrosion additives.
The gaskets that isolate the fluid circuits inside HSD products are made of nitrile rubber:
use only additives that do not degrade this material.
Upon request, HSD supplies “ARTIC-FLU-5” (order No.: H2161H0022).
ARTIC-FLU-5 is a pre-mixed cooling liquid, ready for use and tested by HSD S.p.A.
It contains monoethylene glycol and corrosion inhibitors (based on an ecological formula and
without amines, nitrates or phosphates) and ensures protection against corrosion for roughly 1
year.
ARTIC-FLU-5 prevents the formation of rust, scale and foam deposits, as well as the hardening,
cracking or swelling of the seals and sleeves.
It complies with various international standards, including CUNA NC 956-16.
