Low pressure regulators
In 2003, the NCC announced a change in the regulation of Truma gas regulators. The standard changed from the use of 
bottle mounted regulators to bulk-head mounted regulators and mean that instead of two pressure settings (27mbar for butane and 37mbar for propane) there would be a standard of 30 mbar for both gas types. Today Truma regulators are supplied and fitted to all major manufacturers’ vehicles in the UK.
As many users of caravans and motorhomes will know, over the past few years there have been issues with a contaminant blocking the regulators. Although undecided where the source of the oil residue was, it was found that raising the regulator as high as possible and integrating an elbow (pictured to the right) helped reduce this issue dramatically. Through shear determination and full co-operation between the NCC, Truma and manufacturers in the UK, Truma developed an evolvement of the bulk-head mounted regulator (pictured to the right) that integrates the elbow adaption, making the combined unit, cheaper and more efficient.
