Moody Bible Institute was in need of upgrading their central steam plant that had not been updated since the building was first constructed in the 1970’s. As part of a multi-phase project, McCotter Energy Systems partnered with Elara Engineering to design the replacement hot water plant with 5) 5,000 MBH Riello RTC Condensing Boilers. The first phase consisted of demolishing one of three existing large Kewaunee steam boilers and installing two RTC-5,000’s. Three more RTC-5,000’s were installed in Phase 2, all within the footprint of a single Kewaunee boiler. The entire new Hot Water Plant will be running prior to decommissioning the remaining steam system, ensuring Moody Bible’s central plant will have no downtime. The new RTC Central Plant will combine high-mass condensing boilers, 10:1 turn down Riello burners, and Massimo lead-lag controls to provide the Institute with a maximum efficiency plant.
