HLD 600 automatic: Fully automated integrity test to guarantee highest standards of hygiene

resom stands for practical, efficiency-increasing solutions. In order to create new product safety possibilities for industries such as the food industry, our R&D team has developed a state-of-the-art system allowing for a heavily simplified preventative maintenance of heat exchangers: the fully automated integrity test HLD 600 automatic. This system thus allows for the early identification of damages and micro-biological problems, prevention and thus preclusion of follow-up costs caused by unexpected production stops, repairs, product recalls etc. The resulting tremendous cost-saving potential as well as its simplicity and user safety are among the major advantages of this new method for the automated state examination.

Hydrogen method


resom has recognised the benefits of hydrogen as an optimum basis for high-performance integrity tests and implemented this in the form of the most technically advanced and physically safest methods available on the market: Our highly sensitive hydrogen leak indicator detects the diffusion of H2 molecules through metal and thus specifically identifies material fatigue and defective seals which allows for immediate corrective action. Using this preventative heat exchanger inspection method, one can prevent damages such as the dreaded micro-biological contamination caused by product cross-contamination at an early stage.

Continuous heat exchanger inspection prevents follow-up damages and costs


Regular heat exchanger inspection safeguards the purity of your products in the long run and guarantees highest possible standards of hygiene. We offer two options for straight-forward gas tests: Depending on your requirements, our specialists either perform our hydrogen leak detection directly at your location or create a tailor-made purchase option for you. Thanks to its fully automated controls, you can use the automated leak test yourself easily and, most importantly, with adherence to highest levels of safety. The HLD 600 automatic's operation is easy and intuitive and thanks to its compact construction, it can be used even in difficult to reach places.
