Belgium — 2008-03-20 — INFICON’s refrigerant leak detector combines fast and easy use with superior stability and high precision. Its specially tuned IR sensors detect the smallest amounts of refrigerants in production processes, while being non-reactive to other potential sources of false alarms such as water, alcohol, perfume, or cigarette smoke. In addition to the HLD5000 Smart for the detection of halogenated gases, well accepted by the RAC industry, a special version for the detection of CO2 (R744) is available.

Based on a dual-inlet technology, the concentration of gas at the probe tip is constantly compared to the concentration in the surrounding atmosphere, thereby eliminating false alarms due to background levels of these gases. Featuring easy programming and trouble-free operation of the long-life parts, the HLD5000 offers a very low cost of ownership. It is especially suited for detecting the smallest leaks of R744 and halogenated gases in the production of automotive air conditioning, commercial refrigeration, and heat pump units. The detector’s reliability helps ensure product quality, minimize warranty costs and save time otherwise wasted for finding non-existing leaks.

“We offer a broad range of application-specific leak detectors optimized to meet the high demands of our customers. Following the surge of CO2 technology in different applications, our products will help optimize the manufacturing and product quality of innovative heating and cooling solutions. We are sure that presenting our leak detector on R744.com will raise the visibility of INFICON as a provider of cutting-edge quality control tools,” says Sandra Seitz, Product Manager at INFICON.
