Spirax Sarco has released its new wireless steam trap monitoring system — STAPS Wireless. The system is designed to deliver accurate wireless monitoring and reporting of steam trap performance around the plant. According to the company, it is important for steam users to keep track of the performance of steam traps because leaking or blocked traps waste energy and water, where as a healthy steam trap population allows condensate to be removed from the steam system effectively which means it can be re-used. This helps contribute to reduced fuel costs, energy savings, and reduced water charges.
Honeywell unveiled its new commercial wireless fire alarm system developed to protect challenging applications and high-cost installations, as well as building expansions.
