With the exclusive wave fire-tube design, advancements in Lochinvar combustion technology and the SMART TOUCH™ control with CON·X·US, CREST changed how the industry thinks about fire-tube boilers. Now you have the opportunity to use all of these features in sizes ranging from 750,000 to 6.0 million BTU/hr and delivering up to 96.2% thermal efficiency.

CREST can operate over a wide range of flow rates with very low pressure drop. This permits installation of a full flow (variable primary) system. Installation is streamlined, without the time and materials cost of primary/secondary piping, and pumps needed to maintain flow in a water-tube boiler. Variable flow also makes CREST more flexible at handling frequent fluctuations in the system flow rate.
