Celebrating 15 Years with ESI! Today we’re proud to recognize Ed Taylor Safety Director and Adam Camacho, Senior Mechanical Designer for 15 years of dedication, hard work, and commitment to ESI. Starting in the warehouse as a delivery driver, Ed has taken on countless roles throughout the years, always stepping up wherever needed. From rigging and hoisting operations to supporting the warehouse and sheet metal work, he has been a key part of the team every step of the way. Now leading safety initiatives, he continues to make an impact across the company — and recently earned the 2025 Everett Eames Award. Adam first joined ESI after graduating from Wentworth and returned shortly after. Over the years, he has played a major role in HVAC design/build projects and now leads pre-construction coordination through BIM and 3D design. His expertise and leadership earned him a promotion to Senior Mechanical Designer in 2022. Thank you both for 15 incredible years at ESI!

Another successful chiller plant project completed! Our Centrifugal Service Division recently performed a full scope of maintenance and upgrades on an 18,240 MBH plant with two 760-ton Trane CenTraVac units. The work included purge and oil filter changes, detailed oil analysis to identify any signs of wear, and condenser tube punching to improve efficiency. The team also completed eddy current testing and boroscope inspections to ensure everything is operating at peak performance. To further protect and extend the life of the equipment, we applied professional epoxy coatings to the condenser heads, tube sheets, and waterboxes, calibrated the refrigerant leak detection systems, as well as coordinated independent lab testing to confirm proper water chemistry. Keeping these critical systems running cleanly, efficiently, and reliably — that’s what we do best. Ready to optimize your chiller plant performance? Connect with our team today!
