The ERESCO MF4 portable industrial X-ray generators are designed for reliability in some of the world’s toughest conditions. The new user interface for controlling and monitoring the X-ray setup features graphic visualization and menu driven operation to optimize productivity.

The robust construction of the control and the tube heads make them suitable for operation in ruggged environments. Due to its low power consumption, not only is energy cost reduced, but operation with portable power supplies are made easier. Special power electronics allow for an alternative operation in the field as well as integration into crawlers. Even with reduced weight, the new tube heads comply with the strict requirements of the European X-ray regulations.

The ERESCO MF4 generates a high X-ray dose which allows the shortest exposure time that results in higher productivity by using modern compact electronics to minimize weight and provide a high power output with extremely low ripple, together with a sturdy metal ceramic X-ray tube

Metal/Ceramic Technology

Ensures both continuous operation and a long operating life.

Specially Designed Cooling System

The MF4 cooling system also assists in prolonging long trouble-free operation as its specially designed copper cooler optimises the air flow for maximum cooling effect.

Optimized Exposure

Operation starts from 5 kV to enable optimized exposure of low-density materials, such as aluminum, composites and plastics resulting in high-contrast images.

Low Power Consumptions

The power electronics of ERESCO units provide extremely low power consumption between 1 to 2 kW/h.

Full Graphic Display

Provides intuitive user interface for simple and guided operation.

On-Board Exposure Calculator

Allows determination of the optimum exposure settings and further exposure time reduction through unique ERESCO power mode. Several programming and reporting features to shorten X-ray setup and evaluation times.

Microprocessor platform

Enables fast and safe unit control providing intelligent features, such as automatic tube head identification, autonomous operation with event recording, multi-lingual user interface and different exposure programs.

Portable Digital Control Unit

The portable ERESCO X-ray digital control features modern, power electronics and is ruggedly constructed to withstand heavy use in the field.

The MF4 Control facilitates a ergonomical interaction concept for safe and efficient operation unit operation. Several on-board features, such as Exposure Calculator, Parameter Monitoring or Programming / Reporting tools are simplifying inspections.

A large, back-lit, full graphic, transreflective display allows easy viewing even in very strong sunlight and provides details of the system status in up to 19 languages supporting different character-sets. All operating and setup parameters can be entered by means of function keys, an alphanumeric keypad and cursor keys. Menu driven interfaces complete the ease of use. Alternatively setup parameters can be retrieved from a bank of 250, pre-entered exposure programes, stored in a non-volatile memory. In addition, these programs can be uniquely named or commented and can be downloaded, modified, uploaded and achieved. In power operation, the maximum tube current is calculated and set, so minimising exposure times. Besides interfaces for warning lamps, interlocks and pumps, the MF4 control also offers a serial interface for external control or communication with PC based tools.

MF Technology for constant potential high dose output

The ERESCO MF technology allows the X-ray generator to be operated in power mode, because, unlike competitive generators, itcan drive high tube currents. As a result, continuous power ratings of up to 900 W and high currents ensure that the ERESCO MF4 range of X-ray generators offer the best image definition in the 200 kV to 300 kV class.

A medium frequency output (around 20 kHz) can be used to produce a high power output with extremely low ripple.



The ERESCO MF4 range of X-ray generators finds application throughout the industrial spectrum in the inspection of welds and in the examinations for structural integrity.

Standard Radiographic Inspections

Standard radiographic inspections, such as those carried out in fabrication yards in the oil and gas segment, in power plants, in the automotive sector and in general engineering.


Structural integrity testing in the aerospace segment, where special materials, honeycomb sections and composites demand exceptional tube performance.

Oil & Gas

Oil and Gas segments require inspections in extreme conditions, such as pipeline inspections - both offshore and land-based applications - where equipment have to withstand hostile environment like very low or very high ambient temperature or permanent exposure to salt-water, sand or dirt.
