ENERGY-SAVING EQUIPMENT FOR SPRAY
APPLICATION (CDS-HVOF)
We introduce the Equipment for Thermal Spraying Applications (CDS-HVOF),
the new alternative for the thermal spray industry offering technical and economic
advantages over current Detonation, HVOF and Cold Spray techniques.
ï‚· Operates safely on a variety of fuels e.g., propane, propylene, natural gas.
ï‚· Easy to select spray parameters, providing a wide range of coating properties.
ï‚· Integrated software provides on-screen operator control.
ï‚· Low thermal inputs to substrate during coating.
ï‚· Sprays most commercially available powders.
ï‚· Integrated safety features.
ï‚· Modular system concept allows for easy integration in existing thermal spray cells.
ï‚· Cumulative flame sprayer has weight -15 Kg.
 Uses conventional powder feeders – up 5 kg/h.
ï‚· Adjustable high frequency firing
- 15…30 Hz.

The CDS-HVOF device developed should have a lower cost and material intensity, compared with classical
HVOF and Cold Spray units, the productivity being at the same level, and consumption of the electric power
and gases being decreased many times. Moreover, it will have high service characteristics and can be used as
an alternative at existing workshops for deposition of coatings using available surface preparation
technologies, powders and equipment.
