warmer than the process air temperature (40-50ºC).
Rotor wash
The rotor can be washed with water and a little detergent. Washing the rotor must how-
ever not be carried out unless it is very dirty and is thus not part of the standard
maintenance routine. Contact Dantherm your supplier to obtain a guide to rotor wash.
Warranty conditions The factory warranty is only valid with documented preventive maintenance. Mainte-
nance must have been carried out at intervals of a minimum of six months. The docu-
mentation must be in the form of a written log/journal.
