Pelco NTW0K2000 Liquid-Cooled Stainless Thermal Housing, ZnSe Window
Description
Pelco NTW0K2000 Liquid-Cooled Stainless Thermal Housing, ZnSe Window
The Pelco NTW0K2000 is a liquid-cooled AISI 316L stainless steel housing for thermal cameras, fitted with a zinc selenide (ZnSe) window for the 7.5 to 14 micron band. A double-wall body circulates coolant or cooling air from an external circuit through two 1/2-inch GAS connectors, allowing surveillance of ovens, foundries and other high-temperature areas up to 200°C (392°F) ambient with water cooling. A front air-barrier flange keeps dust off the window; Pelco recommends the NXFIGRU2 filtering group to clean compressor air.

Cooling and air barrier
Connect the two 1/2-inch GAS fittings to a coolant or cooling-air circuit. With 20°C inlet water, 2 l/min holds about 32°C inside at 200°C ambient. Feed the air-barrier flange at 2 to 4 bar through the NXFIGRU2 filtering group to remove compressor oil and particles.

Frequently Asked Questions About the Pelco NTW0K2000
What is the NTW0K2000 used for?
It protects a thermal camera in very hot locations such as ovens, foundries and other high-temperature industrial areas.
How hot can the environment be?
Up to 200°C (392°F) with water cooling and the zinc selenide window, or 80°C (176°F) with air cooling.
How is it cooled?
Coolant or cooling air circulates through the double-wall body via two 1/2-inch GAS connectors from an external circuit.
What does the air barrier do?
A front flange blows air across the window to prevent dust deposits and reduce temperature. Use the NXFIGRU2 filtering group with compressor air.
What wavelength does the window pass?
The 4 mm zinc selenide window passes 7.5 to 14 microns for long-wave thermal cameras. A sapphire-window version, NTW0K3000, is offered for shortwave cameras.
Is a camera or power supply included?
No. Add a thermal camera and, if needed, the ONXWPS1B 100-240 VAC to 12 VDC camera power supply.
