The Model MD85100  Hot Metal Detector's electronic circuitry is packaged in a robust cast aluminum housing. The housing includes a large air cooled chamber which is separated from the electronic circuitry compartment. An air purge inlet is located in the rear of the cast aluminum housing. Pressurized air passes though this chamber, cooling the cast aluminum housing thus cooling the electronic circuitry. The air  vents in the front of the housing via a slot in front of the lens providing air purging. Further cooling of the air can be accomplished with the use of an in-line vortex tube air cooler.

Also, as an option, a sealed water coolant radiator & separate air purging facility can be provided. The copper water coolant radiator is mounted internal to the air cooled chamber. Coolant inlet and outlet fittings are provided in the rear of the cast aluminum housing. An air inlet is fitted in the front nozzle of the housing and air is vented out the front of the nozzle in front of the lens.

For severe environments an additional air purge nozzle can be fitted onto the front of the MD85100 housing. The air purge nozzle is constructed of steel with zinc cadmium, coating and oven baked black paint for long life. This air purge nozzle is used to further direct the air purge and increase the pressure to clear steam and particulate from the lens. Is construction allows for easy attachment to the cast housing with only an Allen wrench. It has an extra tubing fitting if additional air purge is required in severe environments.
