Air-cooling System for Borescope Thermal Imagers adds Protective Options for AMETEK Land Temperature Measurement Solutions

LAND borescopes are designed with a choice of cooling options to ensure optimal performance even in extreme temperatures.

These cooling systems are built directly into the protective housing of the borescope to maintain the equipment’s integrity and prevent overheating during extended use.

The air-cooling option is ideal for applications where the equipment is exposed to moderate heat levels, ensuring consistent airflow to regulate the internal temperature of the borescope. It is ideal for applications where cooling water is either unavailable or cannot be used for safety reasons.

For more demanding conditions, the water-cooling option provides enhanced thermal protection by circulating water through the housing, effectively managing higher temperatures and extending the lifespan of the equipment. 

This dual cooling approach ensures that LAND’s borescopes can be used in a wide range of industrial settings, from routine inspections to high-temperature processes, while maintaining accurate and reliable performance.

For example, in black liquor recovery boilers used in the pulp and paper industry, the MWIR-B-640 mid-wavelength thermal imaging borescope plays a key role in visualising combustion, the smelt bed, and boiler tubes while capturing accurate temperatures and temperature gradients.

This allows optimisation for maximum energy efficiency and preservation of the valuable chemicals that are reused in the kraft process. However, it is important to keep water away from the process, so AMETEK Land’s highly efficient air-cooling system is an ideal solution.

In addition, LAND offers its pneumatic auto-retraction system (LPAR), which automatically removes the camera if it is at risk, safeguarding the instrument and preventing overheating or damage in the event of loss of power, purge flow loss or cooling.

Global Product Manager, Derek Stuart, said: “Taken together, the LPAR pneumatic auto-retraction system and the choice of cooling options allow our near infrared and mid-wave infrared borescopes to be used in a wide variety of industrial applications including furnaces, boilers, kilns and reformers. Water cooling is generally preferred as it is efficient and economical, but air cooling avoids the need for a water supply and allows a borescope to be used in applications such as black liquor boilers where water is not acceptable.”
