Using The Unit On Construction Sites And In Workshops; Working On Or Repairing The Electrical Equipment; Working On Electrical Components; Max. Operating Pressure - Storch HotFlow 55 Mode D'emploi

1.11 Using the unit on construction sites and in workshops

The mains connection should only be established via a special feed point with a residual current protective device (INF ≤
30 mA rating).

1.12 Working on or repairing the electrical equipment

No liability shall be assumed for any repair work carried out improperly. Repairs should only be conducted by an author-
ised STORCH service centre.

1.13 Working on electrical components

Remove the mains plug from the socket before carrying out any work.

1.14 Max. operating pressure

The permissible operating pressure for the heating hoses is 250 bar. Do not use the heating hoses on paint spraying
pumps with a higher operating pressure if they have not been limited to 250 bar.

2. Application overview

2.1 Operational areas

The hot-flow heating hose system has been designed as an accessory for airless paint spraying equipment whose opera-
ting pressure does not exceed the nominal pressure of the hoses (250 bar).
The heating hoses are used heat coating materials to 55° C to optimise the atomisation process at the nozzle. In addi-
tion to ensuring an optimisedspray pattern this also makes it possible to avoid the additional use of solvents. Further-
more, it also reduces material consumption. The heating hose is suitable for both stationary use in workshops or on
construction sites.
Caution: The HotFlow 55 7.5 m heating hose system (art. no. 69 15 05) is suitable for STORCH Airless equipment as
of date of manufacture 10/2011. If you are using a device supplied by another manufacturer, check whether the device is
suitable for 7.5 m hoses.

2.2 Processable coating material:

Water and solvent-based paint (observe the flash point of > 55° C), two-component coatings (observe the pot life),
emulsion paint and latex paint. If you wish to use a different coating material please contact us first as it could adver-
sely affect the functionality and safety of the unit. Only use coating materials that are suitable for airless units and
observe the information provided by the respective manufacturer (technical data sheets): The properties of some coating
material are destroyed through excessive heating. Some material can become highly viscous when heated and damage
the heating conductor in the hose.
2.2.1 Coating material with sharp-edged aggregates
These aggregates have a high wearing effect on the heating wire located in the hose and also on the hose itself. This
adversely affects the service life of the unit.

3. Unit description

The heating hose is heated by an electrical heating conductor located inside the hose. The coating material is heated by
electric current flowing through the heating conductor. The material's viscosity level is reduced as a result of the hea-
ting process. The electronic components in the temperature regulator continuously monitor the preset heating tempera-
ture. The heating capacity of the hot-flow heating system is technically limited.
An excessively high volume flow rate (nozzles too large) or very low temperatures of the coating material prior to use
can be the reason for the temperature of the coating material not being reached. The ambient temperature also has an
influence on the heating capacity of the heating hose.
