Nitrogen Regulators and CP23


Readers may like to be aware of the following from Nick Jones of Express Fire in Manchester and the attached leaflet.

“Many service engineers may not be aware of The British Compressed Gases Association’s Code of Practice (CP23) ‘Application of the Pressure Systems Safety Regulations 2000 to Industrial and Medical Pressure Systems’ which includes a requirement to replace regulators every five years with a new or refurbished unit or to refurbish the regulator with approved spare parts.


Express Fire has recently been working with one of their suppliers to develop a new nitrogen regulator and they are of the opinion that it would be more cost effective to replace the regulators with new every five years for engineers.

As you will see from the information below, the TITAN regulator (pictured left) has a maximum pressure of 20 bar which means that it offers increased safety for operators as it reduces the risk of accidental over pressuring of extinguishers. Whilst available to all customers, as a member of IFEDA, Express Fire would be pleased to offer an introductory 10% discount to all other IFEDA members who wish to purchase the regulator meaning that they can purchase for only £117.00 each plus VAT (plus any applicable carriage charge as detailed in our Terms and Conditions) rather than the standard list price of £130.00.”

The new Titan High Pressure single stage regulators offer a compact option for applications with high outlet pressure requirements of up to 20bar. Used in a wide range of applications from high pressure testing and purging to charging fire extinguishers this regulator is a versatile option for many process gas applications. In addition the regulator features a ball control valve at the delivery outlet port. The regulators cannot deliver more than 20bar, which is high enough to safely pressurise all portable fire extinguishers whilst greatly reducing the risk of accidental over pressurising the extinguisher.
