The CREST® modulating-condensing boiler is now available with inputs up to six million Btuh. The company claims its new CREST 6.0 model will enable engineers, contractors, and building owners to utilize Lochinvar’s patented Wave™ fire-tube design in their largest commercial applications for energy-saving performance. CREST’s SMART TOUCH™ operating system with CON-X-US® remote connectivity features an 8-in touchscreen and multi-color interface. Its built-in cascading component provides total command without external controls or complex control logic programming. The SMART TOUCH operating system can also be integrated directly into a BMS through BACnet, ModBus, and other communication protocols using a gateway device. With CON-X-US remote connectivity, the CREST boiler can be monitored from anywhere, even without a BMS.

With options for installation with primary/secondary piping or in a full-flow arrangement, CREST can operate at flow rates as low as 20 gpm up to a full 550 gpm. Additionally, the system offers a wide variety of horizontal and vertical venting options. Six unique venting options allow CREST to provide l flexibility for placement of units within the building as it permits direct-vent air intake and exhaust runs up to 100 equivalent feet.
