NexRev Inc. says it has developed a new solution to deliver operational cost savings to multisite facility owners. DrivePak Applied combines NexRev’s DrivePak variable flow retrofit technology with its Freedom energy management and control system. The company uses these tools to implement strategies that improve operating efficiency on an expanded range of applied HVAC equipment including chillers, cooling towers, pumps, and air handling units. According to NexRev, customers can realize an attractive ROI with guaranteed results, and flexible procurement options are available to get projects funded, deployed and saving money as soon as possible.
Daikin Applied has expanded its Magnitude WMC chiller line to include four additional sizes – WMC125, 200, 225, and 275. The product is ideal for most commercial applications including hospitals, small to midsized data centers, schools, and office buildings. The company says the expanded line provides greater flexibility for engineers who can now closely match chillers to the specifications of the job and apply magnetic bearing chillers on many more projects.
Our BAS columnist makes a house call to prescribe one method of applying retrofit expertise, including the success story of a hospital with mysteries or maladies that required attention in VAV and chillers, air handling strategies, OR ventilation, and beyond.
A quiet learning environment, consistent comfort, and energy efficiency topped the list of requirements at Northbrook Junior High School in selecting chillers as part of a $1.88 million life-safety improvement renovation project. The two-story, 135,000-sq- ft school was originally built in 1958 and now serves 650 students in grades six through eight. The renovation project included replacement of all heating and cooling system components.
