2.
The following apply to a conveyed medium that is specified as “undefined”
in the fan's technical data sheet:
• The fan is suitable for conveyance of corrosive, hazardous, explosive,
gaseous media that fall under the explosion protection marking of the
fan (explosion group, temperature class) and to which the plastics of
the fan and the sleeves are resistant.
• For independent assessment, the operator is to consult the pertinent
available resistance lists for plastics. The SIMCHEM guide is found on
the manufacturer's website (www.colasit.ch).
The impeller, inlet cover, and housing of the fan are marked with an abbreviation
for material identification (e.g. PPs-el for anti-static, electrically conductive plas-
tic made of polypropylene).
• The order confirmation or the additional specification sheet contains fur-
ther information and notes regarding a potential reduction in service life
of the fan.
3.
The following apply if, according to the operator’s information, the conveyed
medium contains several chemical substances:
• The named importer or the manufacturer confirms the resistance of the
fan to these chemical substances in the order confirmation or the speci-
fication sheet, which is an associated document.
• The service life of the fan can be limited if there is a corresponding note
in the order confirmation or the specification sheet.
Permissible environmental conditions
1.
The permissible operating and ambient temperature ranges are indicated on
the fan nameplate.
The minimum permissible operating temperature for the plastic parts of the
fan is -20 °C.
2.
The following applies if this information is missing from the nameplate:
• Permissible ambient temperature range of the electric motor: See
nameplate of the electric motor or the operating instructions/declaration
of conformity of the motor manufacturer.
3.
At operating temperatures below 4 °C, it is to be ensured by means of a
constant minimum flow rate that
• no condensate freezes in the fan or ductwork.
• no pieces of ice from the ductwork get into the fan.
Procedure for process changes
• The operator is to ensure upon a process change that
• the fan can withstand the zone or parameters changed or the new con-
veyed medium,
• the operating conditions according to the technical data sheet and
nameplate plate are adhered to.
