Refineries run hot and run hazardous. Cooling water circuits keep pumps, exchangers and rotating kit within limits, and a flow failure needs flagging fast.

The Ajax XP ATEX flow switch is designed for potentially explosive atmospheres and is built in the UK by F. Bamford (Instruments) Ltd. It gives a reliable switched output on loss of flow, ready to wire into the plant alarm or shutdown system. With more than 70 years supplying petrochemical sites, Bamford knows what refinery maintenance teams need: kit that fits, works and keeps working between turnarounds.
