Precision drying for complex or water-absorbing parts

Crest Ultrasonics’ vacuum drying systems are a proven effective method for drying parts that trap water because of complex geometries or absorb water onto the surface. Vacuum drying is usually used as a secondary drying method to remove trace amounts of residual water, and is done by placing parts in a heated vacuum chamber to flash off the water. This system is typically used in an in-line, batch configuration.

Vacuum drying is accomplished by creating a vacuum atmosphere that reduces the vapor pressure of molecules on the substrate being dried. The water rapidly reaches its boiling point and is “flashed” off the surface. By pulling a vacuum and thereby reducing the pressure in the chamber, the boiling point of the water in the chamber is reduced and the water is flashed off the surface.

The Crest Ultrasonics vacuum dryer is capable of drawing the chamber down to the desired vacuum in 30 seconds. Parts are placed into the drying chamber to the desired set point. After the preset dwell time has expired, a vent valve opens, relieving the vacuum in the chamber through a 0.2-micron filter. At this point, the parts can be removed.

The upper and lower vacuum set points are controlled via a front panel controller. This controller also provides a direct analog readout of the chamber vacuum.

The system is supplied with safety interlocks. It may be supplied with a wide range of mechanical pump sizes to meet the exact requirements of the application. The vacuum chamber is designed in accordance with all applicable codes and standards. Other electrical construction specifications are available upon request.

Four standard sizes available:

Standard sizes range from 10″L x 14″W x 10″H to 18″L x 26″W x 18″H.
