2. General view of application
2.1 Application
Priming and final coating of large areas, sealing, impregnation,
construction sanitation, façade protection and renovation, rust
protection and building protection, roof coating, roof sealing,
concrete sanitation, as well as heavy corrosion protection.
Examples of objects to be sprayed
Large-scale construction sites, cooling towers, bridges, sewage
treatment plants and terraces.
2.2 Coating materials
Processible coating materials
i
Pay attention to the Airless quality of the coating
materials to be processed.
Latex paint, dispersion paints, fire protection and thick film materials,
zinc dust and micaceous iron ore paints, Airless spray primer,
sprayable glue, anti-corrosive agents, thick coating materials and
bitumen-like coating materials.
No other materials should be used for spraying without Titan's
approval.
Filtering
In spite of the high-pressure filter, filtering of the coating material is
to be recommended in general (except when processing airless joint
filler).
Stir coating material before commencement of work.
i Make sure when stirring with motor-driven agitators
that no air bubbles are stirred in. Air bubbles disturb
when spraying and can, in fact, lead to interruption
of operation.
Viscosity
It is possible to work with high-viscosity coating materials with the
devices.
If highly viscous coating materials cannot be sucked up, they must be
diluted in accordance with the manufacturer's instruction.
Two-component coating material
The appropriate processing time must be adhered to exactly. Within
this time rinse through and clean the unit meticulously with the
appropriate cleaning agents.
Coating materials with sharp-edged additional materials
These have a strong wear and tear effect on valves, high-pressure
hose, spray gun and tip. The durability of these parts can be reduced
appreciably through this.

3. Description of unit
3.1 Airless process
The main area of application are thick layers of highly viscous coating
material for large areas and a high consumption of material.
A piston pump takes in the coating material by suction and conveys it
to the tip. Pressed through the tip at a pressure of up to a maximum
of 228-248 bar (22.8-24.8 MPa, 3300-3600 psi), the coating material is
atomised. This high pressure has the effect of micro fine atomisation
of the coating material.
As no air is used in this process, it is described as an AIRLESS process.
This method of spraying has the advantages of finest atomisation,
cloudless operation and a smooth, bubble-free surface. As well as
these, the advantages of the speed of work and convenience must be
mentioned.
3.2 Functioning of the unit
The following section contains a brief description of the technical
construction for better understanding of the function.
i
This manual gives information for both electric
motor and gasoline engine PowrTwin Plus DI
models.
TITAN PowrTwin Plus DI (PT) are high-pressure spraying units driven
by either a gasoline engine or electric motor.
The gasoline engine or electric motor (fig. 1, item 1) drives the
hydraulic pump (3) by means of a V-belt which is under the belt cover
(2). Hydraulic oil flows to the Speeflo® HydraDrive™ hydraulic motor
(4) and then moves the piston up and down in the material feed
pump (5).
The inlet valve is opened automatically by the upwards movement
of the piston. The outlet valve is opened when the piston moves
downward.
The coating material flows under high pressure through the high-
pressure hose to the spray gun. When the coating material exits from
the tip it atomises.
The pressure control valve (6) controls the volume and the operating
pressure of the coating material.
