Temperature Chamber - EC1XHA models with Ambient Blower Motor

EC1xHA Models

The EC1xHA model temperature chamber offers the same features as our EC1x model chambers with the added feature of an ambient blower. This 200 CFM blower pulls in ambient air from outside the chamber to assist in cooling the interior workspace. It is then vented out the chamber's 3 1/2" diameter exhaust port. The ambient blower feature allows the user to conserve coolant when cooling the chamber down from high temperatures. The ambient blower is mounted on the back of the chamber and can be controlled from commands issued from the front panel, inserted in local programs or through the remote interface.

Temperature ChamberThe EC1xHA chambers may be equipped with optional features such as circular ports ranging from 1" to 4", adjustable shelves, window doors, N2 gas purge and electronic failsafe. Cooling options such as 3 tank LCO2 auto switching, 2 tank LN2 auto switching, LN2 line purge (required to cool long LN2 lines from supply to chamber) and LN2 redundant valve (safety option) may be added as well.

The summary table below can be used to compare the different size EC1XHA chambers. For a comparison of Sun's chambers based on controller style, see our Chamber Comparison Table.
