Indicates a hazardous situation which, if not avoided, may result
in serious injury.
Indicates a hazardous situation which, if not avoided, may result
in moderate or minor injury.
Additional notes, information and tips.
DANGER OF FREEZING
In case of operational conditions with temperatures below zero the sufficient amount of antifreezer (
e.g.Ethelene Glycol) should be added unless the water will stay in the system at still times. In order
to be able to avoid the danger of freezing a sufficient amount of antifreezer solution should be
added to reach a freezing temperature of 7-10 C below the operation temperature.

4. TECHNICAL DATA
4.1 Standards
•97/23/EC PED (Pressure Equipment Directive)
•EN 378 “Refrigeration systems and heat pumps, technical safety and environmental
requirements”
•Capacity standard for dry coolers is defined according to the EN 1048 standard with
the ratio of % 34 ethylene glycol. ( Heat exchangers- Air-cooled liquid coolers dry coolers-
Test methods for establishing the performance )
•The system installer is responsible for that the inherent installation and security
information are harmonized with the valid standards and guidelines (DIN EN 292 /
294).
4.2 Product
The basic principle is to transfer the return water load in the system to air by the aid of a heat
exchanger including fans. Its working principle is that the air sucked by fans cools the fluid
within the tube while it passing through the fins. Thanks to closed fluid circuit, quantity of
water does not diminish hence it is not needed to add extra water to the system.
The unit is delivered for operation with a specific operating point:
•Air inlet temperature and volumetric flow
•Fluid inlet temperature and volumetric flow

13
