We supply our HVAF and HVOF thermal spray equipment to fit existing thermal spray infrastructure (if present) or a new manufacturing cell. Our advanced coating systems provide an easy way to upgrade from HVOF to HVAF equipment.
HVAF Control and Auxilliary Components Include:
- HVAF and HVOF Control Console.
- HVAF and HVOF System Controller with Partitioned Cabinets.
- HVAF Control Console Components: Ignition Box and Hoses.
- High-Pressure Thermal Spray Powder Feeder.
- Zimmer Fuel Vaporizer.
As the Australian distributor for Kermetico HVAF/HVOF equipment, MSSA supply specialised Kermetico equipment for the spraying of metal for Corrosion and Wear Resistance.
HVAF and HVOF Control Console
The Operator Tablet is a rugged industrial computer with the Microsoft Windows CE operating system – the OS specifically designed to work with an industrial PLC. The Tablet features a 8” x 4.5” wide format touch-screen and “Soft Touch” buttons (which are illuminated industrial membrane keys) used for process control (start/stop of the gun, powder feeder, and other devices).
The Tablet has a hard-wired illuminated E-stop.
The whole device with the cable connected is rated IP67 (dustproof and waterproof when submerged under water up to 30 minutes).
The Tablet Touch-Screen Interface through the integrated PLC provides all of the functions necessary for the operator to control the spray gun, powder feeder, and peripheral devices that are connected to the PLC’s electronic blocks (The PLC and electronic blocks are housed in the Controller).
The Tablet program provides many operating windows, giving an operator the interface for setting and monitoring:
- Gun spray parameters
- Powder feeder and peripheral devices parameters
- Warning and safety shut-off alarms and interlocks
- Facility for saving and uploading spray parameter files
HVAF and HVOF System Controller with Partitioned Cabinets
The Controller consists of two cabinets mounted together and isolated from each other:
- General use compartment with devices controlling the air and carrier gas (nitrogen); the electronic control block (with the PLC, electronic blocks, power supplies, relays, etc.) is also located in this cabinet.
- The fuel compartment with devices controlling fuel and hydrogen; all devices and electrical connections certified to Class 1 Group A, B, C, D Division 1.
- The controller is set on 4 wheels, 90 kg (200 lbs.) capacity each.
The controller is set on 4 wheels, 90 kg (200 lbs.) capacity each. Follow this link direct to Kermetico view detailed specifications for the System Controller.
HVAF Control Console Components: Ignition Box and Hoses
- The Ignition box includes a high-voltage transformer enclosed in the NEMA 4 aluminum enclosure for mounting on the robot at a maximum distance of 600 mm (2-feet) from the gun.
- The second electrode is grounded to prevent damage to the robot in the case a transformer or ignition wire is damaged.
- All hoses have a satisfactory rating for pressure and material for each gas line.
- The powder hose is thick wall tubing with grounded static-dissipating strips.
- Powder hose fittings are “field-attachable” (reusable in the spray shop/lab).
- Combined with the features of the High-Pressure Powder Feeder, the supplied powder feed hose provides reliable feeding of very fine powder distributions (even -10/+1 micron) with the relatively low flow of nitrogen carrier gas – under 22 SLPM.
- Reliable spraying of very fine powders is an essential advantage of Kermetico HVAF equipment.
- With the same jet, fine particles are accelerated to a higher velocity than larger particles and they are heated through to a higher temperature than coarse particles, thereby expanding the technological windows of the Kermetico HVAF process.
High-Pressure Thermal Spray Powder Feeder
- The HVAF powder feeder is a rotary powder feeder, which is additionally equipped with an automatic pressure relief valve assembly, activated from the control console.
- The heart of the feeder’s electrical controls is a digital closed-loop controller, offering precise and accurate wheel speed.
- The startup and the shutdown of the feeder and the wheel RPM are remotely controlled from the control console.
- The feeder has an option for manual control.
- Interlocks from the control console provide a safety shutdown when the wheel RPM is abnormally low as compared to preset values, no carrier gas flow detected at the gun during ignition, or carrier gas pressure is lower than the hydrogen pressure introduced into of the powder feed hose.
- The powder feeder provides reliable feeding of both coarse and very fine powders. For example, WC-based powders as small as 1-10 microns are routinely used with this feeder when spraying with our compact hand-held or internal diameter gun using our static-dissipating powder hose.

Zimmer Fuel Vaporizer
Zimmer Vaporizer produces gas from liquid propane (Model Z40 P) or LPG-gas (Model Z40 L) by its electrical heating. Since volumetric consumption of liquid is relatively small, the supply cylinder pressure remains essentially constant.
