Water heat exchanger - maximum/maximum water Δt
The minimum and maximum allowed Δt at full load conditions are respectively 3 °C and 8°C. These values
represent a guideline, please refer to the latest Chiller Selection Software (CSS) for real minimum and maximum
allowed Δt each size. Contact factory in case lower or higher Δt are required.
Minimum glycol percentage for low air ambient temperature to prevent freezing of
the hydraulic circuit
In presence of glycol in the water system the performance will be affected. Refer to the selection software. All
machine protection systems, such as antifreeze, and low-pressure protection will need to be adjusted in
accordance to the type and percentage of the glycol.
Air heat exchanger - Altitude correction factors
Maximum operating altitude is 1800 m above sea level.
Contact factory if the unit has to be installed 1000 m above the sea level.
Available fan static pressure correction factors (for Silver and Gold version only)
The above table is valid for SILVER and GOLD series with standard fans. Application with more than 30 Pa of
external static pressure are not recommended. In case where external static pressure over 30 Pa is required,
contact factory.
Operating limits for Storage Environmental conditions must be within the following limits:
-
Minimum ambient temperature: -20°C
-
Maximum ambient temperature: 57°C
-
Maximum R.H.: 95% not condensing
Storage below the minimum temperature may cause damage to components. Storage above the maximum
temperature causes opening of safety valves.
Storage in condensing atmosphere may damage electronic components.
