Adding a water vapor capture pump increases roll-to-roll coating capacity | Actual measured pumping

Adding a Xieyi water vapor capture pump is a common and efficient solution in the industry for shortening vacuuming waiting time and increasing daily capacity in roll-to-roll coating machines. This test used a mainstream 4-meter wide dual-chamber roll-to-roll aluminizing machine as the actual test object, comparing two operating conditions: one with and without the WVCP3600 water vapor capture pump. The increase in production capacity is quantifiable and visible.

Without the vacuum water vapor capture pump: 38 minutes to reach process vacuum, stable daily production of 12 heats, with the vacuum pump operating at high load for extended periods.

With the WVCP3600 water vapor capture pump: Vacuuming time reduced to 14 minutes, single-cycle vacuum compression exceeding 60%, stable daily production of 19 heats.

Under the same factory, equipment, and labor conditions, the annual output of a single machine increases by 55%, expanding production capacity without the need for additional roll-to-roll coating main units.

A stable low-moisture vacuum environment reduces downtime due to substandard vacuum levels and rework of waste membranes, increasing equipment uptime by 28%. Although the WVCP water vapor capture pump refrigeration unit generates basic power consumption, the significantly reduced vacuum pump runtime leads to an overall 18% decrease in workshop energy consumption. Shorter pumping wait times are a direct benefit, while the improved yield and material savings resulting from a stable vacuum environment represent the core long-term production value of water vapor capture pumps.
