Does your natural gas spot sampling procedure comply with industry standards GPA 2166 and API 14.1? These gas sampling standards recommend that the sample cylinder be preheated to a temperature above the hydrocarbon dew point of the flowing gas before collecting a gas sample. Our GCH heaters for 300cc and 500cc 2 inch diameter cylinders provide a simple efficient solution to cylinder preheating for spot sampling. Field testing has proven that the GCH heaters improve sampling accuracy and reduce or eliminate bad samples due to heavy liquids accumulation in the cylinder. GCH heaters provides a simple, efficient solution to cylinder preheating. It consist of a heater enclosure and a controller. The sample cylinder is preheated inside your vehicle on the way to, or at, the sample location. Heating takes about 10 minutes. To use the GCH heater just insert a clean empty cylinder into the heater enclosure and connect the controller cable to the heater. Power for the heater is taken from a vehicle 12 volt power point or cigarette lighter plug. While heating, the sample cylinder’s temperature can be monitored using the controller’s display. When fully heated, the controller will keep the cylinder at the set temperature (140°F) until you are ready to disconnect the controller from the heater and take the sample. The hot cylinder stays in the heater enclosure until the sampling process is finished to provide a safe method to handle the heated cylinder while taking the sample without the need for gloves
