Heat Vacuum Applicator (HVA)

‍

The system is composed of three main components; a hinged lamp bank hood, a hinged upper diaphragm (bladder), and the lower diaphragm base frame.  The objective of the machine is to create a closed system around an object that has been placed on the lower diaphragm.  To do this, the upper diaphragm is lowered onto the object and held down using the two smaller hydraulic cylinders.  This creates a closed system from which the air between the two diaphragms may be removed by the vacuum pump. Once a user specified vacuum level has been achieved, then heat may be applied for a specified amount of time.  Heat is provided by a field of infrared light bulbs located within the lamp bank hood.  The hood is lowered onto the upper diaphragm prior to turning the lights on.  The cylinders that raise and lower both the hood and diaphragm are hydraulically powered and they have accessory rod locks that hold the position of the cylinder in the event of a pressure or power loss. Windows are provided on the hood front and sides to visually check light bulb function.
