Raytek A-T40-WC Air/Water-Cooled Housing


Out of stock



The air/water-cooled housing allows the sensor to be used in ambient temperatures up to 120°C (250°F) with air
cooling, and 180°C (356°F) with water cooling. The cooling media should be connected using 1/8” NPT fittings
requiring 6 mm (0.24 in) inner diameter and 8 mm (0.31 in) outer diameter for the tube. Airflow should be 1.4 to
2.5 l/s (0.37 to 0.66 gallons/s) at an air temperature of 25°C (77°F). Water flow should be approximately 1.0 to
2.0 l/min (0.26 to 0.52 gallons/min) at a water temperature between 10 and 27°C (50 to 80.6°F). Chilled water
below 10°C (50°F) is not recommended.

The Air/Water-Cooled Housing is made from stainless steel and is delivered with air purge. The air purge should be always used to keep the lens dry.

For ambient temperatures exceeding 175°C (350°F), the ThermoJacket can be used. This accessory allows
operation at ambient temperatures up to 315°C (600°F)!
