Lochinvar – Crest Condensing Commercial Gas Boilers
CREST CONDENSING BOILER
The performance of the CREST boiler has changed the way the industry views fire-tube boilers.
Up to 96.2% Thermal Efficiency
12 Inputs from 750,000 to 6 Million Btu/hr
Up to 25:1 Turndown Ratio
Flexible Flow Rates up to 600 gpm
Features CON·X·US® Remote Connectivity and SmartTouch™ operating control
THE FIRST NAME IN EFFICIENCY
CREST boilers are equipped with a top-mounted micro-metal fiber burner, engineered specifically for fire-tube technology. The system is designed to ensure smooth, quiet modulating combustion with up to 25:1 turndown. CREST is designed for efficiency to reduce your customer’s fuel bills.
Reduce Installation Cost with Variable Flow Technology
Installation is streamlined, without the time and materials cost of primary-secondary system/boiler piping.
High Efficiency with Minimum Supply Pressure
CREST operates reliably with supply gas pressure as low as 4 inches water column. Negative regulation (neg/reg) technology draws gas into a pre-mix combustion system instead of relying on utility pressure through the gas valve. Operation is steady in low gas pressure systems or when peak gas supply demand occurs.
Peace of Mind When It Matters Most
Cascade redundancy provides peace of mind because it helps ensure that a CREST boiler system will always deliver reliable performance with no downtime. Cascade sequencing can be programmed for Lead-Lag or Efficiency Optimized operation.
Flexible Venting Options
CREST offers 6 venting options, and it permits direct-vent air intake and exhaust runs up to 100 equivalent feet using PVC, CPVC, polypropylene or stainless steel pipe. Plus, multiple units can be common-vented to reduce time and materials cost.
Superior Fire-Tube Heat Exchanger Design
The patented Wave™ configuration creates turbulence as flue gas products flow down the tube, scrubbing the energy from the flue products. The Wave design enhances the life of the heat exchanger by allowing the tubes to flex so they operate stress free with none of the adverse effects suffered by traditional fire-tube boilers.
