What is the working principle of the WVCP water vapor capture pump? A dedicated vacuum water vapor c

The Xieyi WVCP series water vapor capture pump is specifically developed for large-volume roll-to-roll coating chambers. It is a dedicated vacuum water vapor capture pump for mainstream roll-to-roll coating machines, achieving a water vapor capture efficiency of over 95%, perfectly solving the problem of water vapor accumulation in the vacuum chamber of roll-to-roll coating.

Core Cooling Mechanism: Built-in cascade refrigeration unit, cold coils stably maintain -120℃ to -135℃, water vapor in the vacuum chamber directly sublimates into ice upon contact with the low-temperature surface, rapidly reducing water vapor partial pressure and achieving efficient water vapor treatment for roll-to-roll coating; Dedicated Roll-to-Roll Structure: Low-resistance, large-diameter coils do not obstruct the film's path, supporting both built-in chamber and high-vacuum valve front-end installation methods, compatible with all models of roll-to-roll coating machines; Fully Automatic Patented Defrosting: Matches the high-frequency door opening and roll-changing conditions of the roll-to-roll machine, automatically heating and defrosting upon door opening to prevent atmospheric water vapor from adhering to the coils and causing ice formation; Closed-Loop Mechanical Refrigeration: No liquid nitrogen required throughout the process, no consumables filling, avoiding freezing damage and tank explosion risks, with annual operating costs only 25% of liquid nitrogen cold traps; Production Line Linkage Design: Standard signal interface, can be linked with the roll-to-roll coating main unit PLC, automatically starting the WVCP water vapor capture pump when the door is closed, achieving fully automated operation.
