ID CoolFlow mono HP HVOF torch

The ID CoolFlow mono is designed for nano- HVOF applications. Especially developed for high pressure, temperature controlled internal HVOF spraying. Operating at reduced power levels, the ID CoolFlow mono applies coatings at reduced substrate temperatures. The ID CoolFlow mono can coat internal diameters
down to 80mm.

The combination of the ID CoolFlow mono with the CPF powder feeder for ultra fine powders of <10µm is ideal for the spraying of thermo- sensitive components. The use of ultra fine powders allows a power level affecting the substrate of less than 20kW. WCCoCr with powder size fractions between -30+15µm and -10+5µm can be sprayed at reduced power levels. These low power levels, combined with an additional air cooling, allow for a very short spray standoff while maintaining a substrate temperature below 200° C. The resulting coating shows increased hardness and low porosity. Powder is applied at up to 40 g/min with a DE of up to 50 %. This high performance is the result of the unique combustion chamber design. The ID CoolFlow mono achieves a combustion chamber pressure of 7 to 18 bars.

The ID CoolFlow mono is a small and lightweight torch, weighing only 2.0 kg including its base unit. The ID CoolFlow mono gun has a full metal housing and is equipped with one radial powder injector. Standard extensions up to 1.5 meters are available to allow access to the most difficult to reach areas.
