Raypak’s XVers commercial fire-tube boilers offer installation flexibility, easy commissioning, optimum seasonal efficiency and long-term reliability, the company notes. The XVers is equipped with Raypak’s VERSA IC, which combines modulating temperature control, safety limits and ignition programming into one user-friendly integrated control platform. The VERSA IC system can be remotely monitored through the Raymote mobile app or web dashboard. XVers can be configured with the HO2T system. HO2T continuously monitors the oxygen level of the flue gas in the vent piping. HO2T extends the life of your equipment by maintaining the optimum fuel to air ratio, the company says.
