CREST Condensing Boiler – Lochinvar
Lochinvar’s CREST Condensing Boiler family is engineered to achieve higher thermal efficiencies in major commercial applications. The company reports that its CREST Condensing Boiler upgrade provides up to 96 percent thermal efficiency in six models ranging from 2.5 million to 6 million Btuh. Lochinvar product development engineers found even greater energy savings for large commercial facilities by manufacturing the new CREST boiler models with an upgraded combustion system and an updated 316L stainless steel heat exchanger. This fire-tube design transfers heat to surrounding water even more efficiently than previous models.
The CREST boiler features an enhanced modulating burner that delivers a turndown ratio up to 20:1 and flexible flow rates up to 600 gallons per minute to meet the needs of large commercial applications.
The boiler communicates in real time with building management systems by utilizing an on-board Modbus or BACnet MSTP protocol. And with CON·X·US®remote connectivity, which is a standard feature, commercial facility managers and building owners can monitor and adjust equipment controls on a CREST Condensing Boiler from a mobile app available on most smart devices.
The CREST boiler offers commercial installers six venting options and permits direct-vent air intake and exhaust runs of up to 100 feet using AL29-4C stainless steel vent pipe on all models as well as CPVC, PVC, and Polypropylene on the 2501-3501 models.
