Essex X-Ray & Medical Equipment

What Essex X-Ray & Medical Equipment does

Essex X-Ray & Medical Equipment Ltd is a privately-held UK manufacturer founded in 1968 and headquartered (since May 2025) in a new 60,000 sq. ft. facility at Horizon 120 Business Park, Braintree. The company designs and manufactures high-voltage interconnects, cable assemblies, and receptacles spanning from 10kV up to 1 megavolt DC, with proprietary expertise in EPR X-Ray cable (rated up to 320kVDC), resin-bonded boron carbide neutron shielding, and vacuum casting/encapsulation services. It operates under majority ownership of Heico Corporation (Miami, USA) via the HVT Group holding structure, alongside sister companies Dielectric Sciences and Connectronics, and serves customers across medical imaging, scientific research, aerospace, defence, metrology, oil & gas, renewable energy, and electronics.

The company's product portfolio spans HV core cable (medical, industrial, analytical/NDT, and high-energy/pulsed power variants), standardized interconnect systems (feedthroughs, switches, encapsulated transformers, subsea interconnects), resin vacuum casting and encapsulation/potting services, neutron shielding and detectors, a recently introduced R30 spring-loaded connector (2025), and bespoke special projects for marquee scientific installations. Revenue is generated primarily through hardware sales of custom-engineered and standardized HV cable assemblies and interconnects, complemented by professional services revenue from resin casting, encapsulation, and diagnostic test-and-repair work. Distribution combines direct enterprise field sales with an approved distributor and sales-representative network covering Japan, South Korea, China, Germany, Italy, France, Russia, and India, with activity reported in over 40 countries.

Customer engagements include high-specification scientific infrastructure programmes - DESY XFEL (>100km of custom pulse-modulator cable), ITER (Gyrotron PSU interconnects at 55kVDC), CERN (200kV isolator adapters), the European Spallation Source, and Rutherford Appleton Laboratories - alongside military applications such as BAE Systems' Eurofighter Typhoon lightning strike simulator and an established medical OEM supply relationship for CT and angiography X-Ray systems. The company holds ISO 9001:2015 certification and RoHS compliance, employs 51-100 staff, and continues to invest in HV design engineering recruitment alongside its capital expansion programme.
