• Special shapes like oval, elliptical and rectangular
Vacuum and heated chambers for advanced helium leak tests
kompaflex own advanced helium leak test facilities consisting of two chambers:
• Large heatable test chamber, inner length 3200mm, inner diameter 1690mm
• Large vacuum chamber with various connection possibilities inner length 4100mm,
inner diameter 1690mm
• PhoeniXL300 from Leybold
• UHV-Pumping bench incl. various pre-pumps
• Electronical recording device Yokogawa
Vacuum-tight welding technology
TIG and plasma welding are the most commonly-used welding procedures at kompaflex. All of our welders have the required training and experience to weld vacuum-tight.
Strict production processes and modern cleaning procedures guarantee clean surfaces to meet the requirements of the vacuum technology entirely. Welding seam tightness is especially important in the high and ultra-high vacuum range.
At kompaflex, we achieve helium leak rates of up to <1*10 Pa*m3/s.
Welding competencies:
• UHV tight welding seams according to specified leakage rates
• Certified welders and procedures (EN, ASME, etc.)
• TIG welding
• Plasma welding
• Welding without any gaps
• Manufacturing in a pressurised clean room
Clean room and Packaging
kompaflex own a modular clean room with an area of 800m2 and a 3.2 t crane which allow the handling of also large expansion joints. A constant over pressure, special building material and strict rules always guarantee to meet customers' high demands and quality specifications of cleanliness.
Expansion joints can be individually packed in plastic bags and can be filled with nitrogen to ensure that they leave kompaflex protected and reach the customer in perfect condition.
