1.4 FIELD OF APPLICATION
They must be used within the application limits stated in the TECHNICAL DOCUMENT.
Units with glycols:
Indoor version
Units containing glycols in the indoor version of the primary circuit are designed and built to operate at outdoor temperatures
between +3° C and +45° C. They therefore do not provi de the installation of heating cables to protect the internal
components. For operation at temperatures outside of the aforementioned range, it is necessary to contact our Technical
Office.
Outdoor version
Units containing glycols in the outdoor version of the primary circuit are designed and built to operate within the following
limits, whose values depend on the percentage of glycol in the primary circuit.
With a 20% concentration of ethylene glycol, the minimum admissible temperature is -5° C
With a 30% concentration of ethylene glycol, the minimum admissible temperature is -10° C
With a 40% concentration of ethylene glycol, the minimum admissible temperature is -20° C
The overall maximum admissible temperature is 45° C
