ST-7 / ST-8 Optional Two Stage TE Cooling
and Water Assist Package *

  An enhanced cooling package is available for the ST-7 and ST-8 cameras for use in warm climates or for anyone wishing to get that extra bit of performance out of the camera by additional reduction of the dark current.  The enhanced cooling modifications are made at our plant to new cameras at the time of order or may be retro-fitted to any existing ST-7 or ST-8 camera.   

The optional enhancement package consists of the addition of a second thermoelectric cooling stage and second 110VAC TE power supply (not shown), new heat sink, larger fan, connections for additional water cooling (may be different than shown) and an optional 110VAC submersible water pump with tubing.  The enhanced cooling package will result in an additional 6 degrees C of cooling (- 31 degrees C minimum from ambient) with air only, or an additional 15 degrees C of cooling (-40 degrees C minimum from ambient) with water assist.
