Seiler Vakuumtechnik is a German equipment manufacturer specializing in industrial helium leak testing. Its website highlights more than 35 years of experience and positions the company as a systems supplier for modern stationary helium leak detection systems, serving the automotive, electrical engineering, refrigeration/air-conditioning, and other manufacturing industries. Its core value is not simply selling standalone instruments, but providing complete leak-testing processes, fixtures, equipment, and services around the customer’s test parts.
Its product line includes modular helium leak testing systems MLTS, customized helium leak detection systems, helium recovery units, test chambers and fixture manufacturing, as well as outsourced leak testing services for prototypes and small batches. The typical workflow starts with the customer providing 3D data, followed by requirements clarification, quotation, mechanical and electrical design, manufacturing and assembly, control program development, internal testing, pre-acceptance, delivery and installation, and final acceptance. The website also mentions remote maintenance and on-site service.
The website does not publish any standard pricing or packages. Given that most of its products are custom industrial systems, pricing is likely to depend on factors such as the size of the test part, leak detection sensitivity, cycle time, automation integration, the complexity of vacuum chambers and fixtures, and whether helium recovery is included. Outsourced leak testing also requires a quote; the website only states that it can test components up to around 1.2 meters wide and 2 meters long.
The main advantages are its strong industry focus and relatively complete engineering delivery chain. The claim that 95% of its systems are manufactured in-house suggests strong control over quality and delivery timelines. Its ISO 9001:2015 certification, around 1,000 systems delivered, and the statement that most are still in operation are also useful signals for industrial procurement. The drawbacks are that the website provides limited technical specifications and lacks downloadable datasheets, typical cycle-time data, leak-rate ranges, and detailed case studies. As with most custom equipment, procurement cycles can be long, with relatively high upfront communication and validation costs.
It is suitable for manufacturers of automotive components, high-voltage electrical equipment, refrigeration and air-conditioning parts, and other products requiring highly reliable sealing tests. It is especially relevant for customers planning to integrate leak testing into production-line quality control or reduce helium consumption. It is less suitable for users who only need a portable general-purpose leak detector, a low-cost lab tool, or a simple one-off test.
The official website is directly accessible and offers content in German, English, and Spanish, but no Chinese interface was found. The contact page lists representative channels in Shanghai and Xiamen, which is a plus for pre-sales communication, installation services, and after-sales response for customers in China.
