The HVCW spray system is a new supersonic combustion process using Wire.
This system combines the superior coating quality of high velocity spraying with the convenience and reliability of wire feeding.
HVCW SPRAY SYSTEM
HVCW SPRAY SYSTEM
- The HVCW spray system is the nozzle external combustion type high velocity flame spray system.
- This combustion is based on propane gas and oxygen, but air is also used to assist combustion and increase flame jet speed.
- The speed of flame jet generated by the combustion of propane, oxygen and air reaches a high speed of 2700 ft/sec.
