Cooler specifications and hydraulic connections
The hydraulic connection points are shown in paragraph 5.6.1 “Hydraulic connection points”
together with the technical features.
For the cooling circuit, use demineralised water (minimum 75% volume) with 10% of ethylene
glycol and anti-corrosion additives.
The gaskets isolating the fluid circuits inside HSD products are manufactured in
NBR: use additives that do not degrade this material.
In concentrations above 15%, even the ethylene glycol can damage the seals.
On request, the manufacturer can supply "ARTIC-FLU-5" (order code: H2161H0022).
ARTIC-FLU-5 is a pre-mixed ready-to-use liquid coolant tried and tested by the manufacturer.
The product contains monoethylene glycol and eco-friendly corrosion inhibitors, without amines,
nitrates or phosphates, and can guarantee protection against corrosion for approximately 1 year.
ARTIC-FLU-5 prevents the formation of rust, scale and foam deposits as well as hardening,
cracking and swelling of seals and couplings.
It complies with various international standards, including CUNA NC 956-16.
Type of alternative water additives
In case of emergency, it is possible to use demineralised water mixed with a "cutting emulsifiable",
according to the concentrations indicated in the following table.
It is not recommended, however, for long-term or continuous use.
To protect the product from corrosion, do not use just water (without additives).
