Cooling & Cleaning in Harsh Paper Machine Environments
ProClean Technology keeps cameras clean 24/7
Web monitoring cameras are kept clean under harsh wet end conditions with the aid of instrument air flow. The air is blown through a 5 mm hole in front of the camera housing. As the air flow speeds up when passing the pinhole it forms a strong protection against dirt and prevents water and dirt from entering the camera housing. The housing has no protection window that could get dirty or wear out. The camera is equipped with a dedicated pinhole zoom lens capable of viewing through the hole.
The benefits of pinhole cleaning are trouble-free operation, low air consumption, 100% continuous visibility and the simplicity of the concept. There are no moving and wearing parts: wipers, electronics or controlling components. Continuous air flow enables Pinhole cameras to film undisturbed 100% of the time without washing cycles or wiper movements causing blind times during the cleaning process.
Camera Cooling
Cameras are cooled by using the same instrument air as for pinhole cleaning. Temperature insulation inside the camera housing reduces to some extent the need for cooling. In some positions warmer than 60 C/ 140 F it is necessary to use a Vortex cooler to guarantee a suitable ambient temperature for the camera. In extremely hot positions like in modern impingement dryers reaching 200 – 250 C/390-480 F ambient temperatures, it is necessary to use water to cool the cameras.
Strobing Keeps LED lights Cool
Procemex web monitoring and inspection lights use strobe lighting, which has low energy consumption and remains cool even in hot positions.
This makes them a perfect choice for positions with potential fire risks e.g. in dryer sections. The web monitoring strobe LED lights are in stainless steel housings along the paper making process. They have been designed to take ambient temperatures up to 250C/480 F and have an indirect cooling system for hot positions.

How to save energy through Procemex Air Consumption Management
Cooling cameras and lights in different machine positions can require a substantial amount of cooling air. As the number of cameras along the paper machine has increased in recent years, the selection of an optimized cooling method is becoming increasingly important in reducing air consumption.
Reduce air consumption by 10–40%
Procemex Air Management System offers new tools to enhance paper and board mills’ energy efficiency and sustainability. Air consumption can be reduced by
- using chained & shared air for cameras and lights
- using water cooling for lights
- fine-tuning air flow based on measured real need
