Valmet Visible Thermal Imaging System

Valmet Visible Thermal Imaging System is a rugged, air-cooled, HD visible camera paired with a high-resolution thermal sensor for real-time product temperature measurements. Designed for comprehensive observation and analysis of kiln environments, the Valmet Visible Thermal Imaging System provides unparalleled image quality from start-up to full load conditions.

System benefits:

  • Improved monitoring resulting in reduced operating costs
  • Combustion optimization resulting in fuel savings
  • Allows for visual evaluation of flame shape and size
  • Reduced maintenance costs
  • Greater visibility during start-up and at full load
  • Product temperature alerts
  • Historical temperature data trends

Reliable lime kiln camera system

Valmet Visible Thermal Imaging Systems are engineered for durability and longevity inside of hot, dusty environments, providing a low maintenance solution to many complex process challenges. Digital-only data transmission improves reliability of video streams and nearly eliminates unwanted noise or image signal degradation.

Configuration flexibility

The Valmet Visible Thermal Imaging System can be configured to meet your project budget needs. A Sliding Rail mount provides a reliable, yet economical mounting solution with a small installation footprint. Additionally, the kiln camera system can be purchased with an automated retraction system, which will retract the system on loss of power or air pressure, protecting the camera unit from unintentional damage in the event of cooling air loss.
