This is where it all started. Ajax instruments were originally designed to protect large diesel engines, and that pedigree still shows in every unit.

On drilling rigs, diesel engines drive generators, mud pumps and more. Cooling water flow is critical. An Ajax flow switch on the jacket water or raw water circuit gives early warning of pump failure or blockage. Where engines sit in hazardous areas, the XP ATEX flameproof range applies. Made in Stockport, built to take the knocks.
