Qualitek SprayTek
Spray System

The SprayTek air-atomized moisturizer system applies a fine, controllable mist to the webs or liners to counter warp. The heart of the SprayTek is the patented SprayTek nozzle. The benefits of the patented SprayTek nozzle are:
Integration with Qualitek QCS and PCS systems Companies in the converting industry manufacturing quality paper require a consistent sheet moisture profile along the entire length of the production line. Using the spraydampener in the process a good moistening without formation streaks and with controlled percentages of atomized water will result in a better converting and machine process. The Qualitek SprayTek a member of the Qualitek Actuator Family is the industry standard for spraydampening system. The proprietary fine droplet nozzle technology allows Qualitek systems to provide a solution tailored to your special requirements. Advanced Actuator Control Systems Description The most important characteristics of a fine droplet spraydampening system are its profiling capability and its ability to control the average moisture level. These two characteristics improve the sheet's cross-directional moisture profile and optimize the paper machine's productivity and runability. |
The critical proprietary components of the system are the Qualitek two-stage nozzles that create a balanced mixture of air and water which meets your application requirements. The water nozzles are located in the center of the air nozzles. Directional vanes integrated into the nozzle create a rotational air flow from the nozzle. The rotating air pulls the water from the nozzle and transforms it into a highly atomized, full cone spray pattern that is efficiently applied to the web. The fine droplet size increases the absorption into the web. The Qualitek SprayTek system consists of a sprayboom on which patented, two-stage nozzles are mounted; control station; air supply unit and water supply unit. Control Station is for operation of the spray dampener. Each single nozzle is connected with an individual flow meter and regulation valve for selective water control. The total flow is automatically measured and shown on a display. An integrated solution with PLC for all systems. The complete process can be integrated in the control process station. It contains the integrated MD/CD control, the operator visualization package, PLC functions and the intelligence to control the entire actuator control system. Page 1 of 3 |
