Hattersley Fig 2900 2910 Thermometer - 000TH2900JW

The CONCOA 308 Series is an electrically-heated, single-stage regulator designed for high-flow carbon dioxide and nitrous oxide in laboratory applications. To prevent freeze-up caused by dry ice formation at high flows, it features three integral 50-watt heating cartridges, a primary thermostat for automatic temperature control, and a secondary safety thermostat cutout that heats the regulator seat directly. The 308 Series can be factory-configured with options such as single-station manifolds, purge, low-pressure alarms, or multiple inlets.

• Three 50W heaters maintain gas flows up to 350 SCFH (165 LPM)

• NEMA 4 housing for safe indoor/outdoor use

• 316L stainless steel diaphragm prevents inboard diffusion

• CAPSULE® seat design with 360° integral filtration

• Low wetted surface area reduces purge requirements
