Doser Purge Heater The BCE Purge Heater

Gaseous nitrogen is used in the food and beverage industry to remove oxygen from products, thus increasing shelf life. The handling of liquid nitrogen through the piping and the injection systems that deliver the "nitrogen dose" into food and beverage containers presents unique challenges.

For food & beverage producers, lost production is calculated in downtime. Moisture and freeze-ups are the main contributor to downtime with production line gas dosing systems.  It takes only a very small amount of moisture to freeze up and stop equipment. It’s imperative maintaining reliable and productive dosing process and overcome moisture and frost contamination. The start-up and shut-down times for the dosing systems are another critical area for production efficiency when you consider many dosing systems requiring thaw periods of up to 24 hours.


BCE is pioneering the design of an electric heating element used in purging systems for nitrogen dosers. Heated purging systems remove moisture that migrates into the dosing system and cause freeze-ups, leading to poor operation or complete shut downs of the dosing system.
