SEIFERTERESCO 42 MF4Portable air-cooled 200 kV X-ray generator with 3 mm focal spot
The ERESCO 42 MF4 is a very reliable, portable 200 kV
industrial X-ray generator also for use outdoors in the field
and under challenging environmental conditions.
The ERESCO 42 MF4 offers a material penetration of up to
42 mm steel with 10 minutes exposure time.*
The X-ray tube head consists of a sturdy metal-ceramic
X-ray tube and high voltage generator integrated into arugged compact housing. The air-cooled 200 kV/ 900 W
end-grounded X-ray tube is thermally protected forextended life.
The high voltage generator generates high-stability constant potential voltage at higher efficiency than conventional line frequency equipment.

Additional Features• Rugged construction with proven reliability• Extended operating range from 5 kV to 200 kV enables
flexible use• Gas insulated high voltage section reduces size & weigh• End-grounded, Be-window, metal-ceramic X-ray tube
• DC voltage operation• Modern power electronics provides high stability• On-board real time clock supports fully automatic
warm-up• Large 40° × 60° emergent beam
• Optimized air-flow cooling for efficient heat dissipation• 100 % duty cycle at 30° Celsius (86° F)• Built-in fail-safe warning lamp
• CE certification according to EMC and Low Voltage
Directives• French Standard NFC 74 100 compliant• BfS certification (PTB approval)• Water / dust resistant in accordance with protection
class IP65
• Produced under ISO 9001 certified quality management
systemStandard Delivery Scope
ERESCO generator unit from high voltage generator andX-ray tube or optionally as a system with "ERESCO MF4Control" control unit

The performance of the X-ray tube and the high voltage
generator is continuously monitored for protection andoperational safety. An on-board real time clock facilitates
fully automatic warm-up routines for optimized and timesaving tube conditioning. The flexible connecting cable isheavy-duty and light weight.
The ERESCO series can also be controlled by PC or laptop
and is compatible with the Waygate Technologies software
Rhythm Insight RT.
