Greenheck’s new Energy Recovery Filter System incorporates energy recovery technology into kitchen exhaust hoods. The system captures the waste heat produced by the cooking appliances that would otherwise be exhausted from a kitchen hood and uses it to preheat a portion of the incoming water supply that is directed into the patented energy recovery filters.
Trane has expanded its ductless portfolio to include the new Trane® Water-Source VRF Ductless Systems. The company reports that the new systems provide energy-efficient climate solutions for multi-tenant and diversely occupied buildings, including commercial real estate, and K-12 and higher education facilities.
Johnson Controls is bringing Simplicity® Smart Equipment (SE) controls to its Luxaire® brand of commercial packaged and split system products. Soon to be standard on all 3- to 40-ton packaged units, the updated Simplicity SE controls are designed to make equipment easier to install, operate, and service. They are also capable of providing information that ensures an HVAC system is performing to specifications.
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. The Smart Wireless Integrated Fire Technology (SWIFT) detectors and modules integrate with new and existing fire alarm systems from Fire-Lite Alarms, Gamewell-FCI, and NOTIFIER.
