In view of the importance of safeguarding laboratory employees against hazardous substances, it is essential that lab ventilation systems be designed for reliable long-term performance. In addition, regular maintenance should be allowed for by laboratory architects and planners. For years now, the Trox Labcontrol system has been providing laboratories with superior safety, reliability and comfort that reduces operating costs. In laboratories, usage changes must be implemented, and the causes of alarms eliminated, as expeditiously as possible in order to minimize down time and its attendant costs. Lonworks technology, which is used systematically in all Labcontrol systems, allows Trox remote maintenance systems to deliver reliable, expeditious and cost-effective support. The Labcontrol system can be visualized via conventional telecommunications technology (telephone, internet) and monitored online. It can also be customized for special needs. Remote maintenance allows technicians to provide efficient and cost-effective on-site service.
