This listing is for the Ideal Vacuum XtremeFreez XFT-4, four liter refrigerated vapor trap, with digital temperature display. It protects vacuum roughing pumps from harmful vapors which can damage the pump or shorten its life. The trap uses mechanical refrigeration which is efficient, cost effective, and saves energy. It eliminates the ongoing need for expensive and potentially dangerous consummables, such as liquid nitrogen or dry ice.

When vapors, such as water vapor, volatile alcohols, petrochemicals, or any other condensable gaseous compound mix with the vacuum pump’s lubricating oil, the oil breaks down, lubricity is decreased, and the pump’s lifespan is reduced.

The XtremeFreez vapor trap uses two compressors in a cascading refrigeration configuration to chill the wall of a built-in, round, insulated, stainless steel vessel (trap). Refrigerant flows through copper piping wrapped around, and brazed onto the walls of the trap. The walls are cooled to -90°C.

The trap is sealed by a removeable top cover plate or glass insert with two through ports. Air or gas from the chamber enters the trap through the central port. Condensable vapors with a freezing point above -90°C are condensed on the trap’s cold wall where they freeze and become ice. Remaining non-condensable vapors are pulled through the second port of the trap’s top plate and into the roughing pump’s inlet.

The compact XtremeFreez vapor trap is available in two models. The XFT-4 has a 4 liter vessel, and the larger XFT-8 model has an 8 liter vessel.
