Electrically-heated, single stage regulator for carbon dioxide and nitrous oxide laboratory applications
The CONCOA 308 Series electrically heated regulator provides primary pressure regulation of high flows of carbon dioxide or nitrous oxide in critical laboratory applications. As carbon dioxide or nitrous oxide passes through the regulator seat, dry ice can form if the flow is too high, causing the regulator to freeze up. The 308 regulator has an integral heating system consisting of three heating cartridges, a primary thermostat for automatic temperature control, and a secondary safety thermostat cutout. This system directly heats the regulator seat to mitigate ice buildup and prevent freeze-up problems. Available with a variety of options installed at the factory, the regulator may be configured as a single station manifold with or without purge, low-pressure alarm, or multiple inlets.
