The Riello Array is a pre-packaged boiler plant, the new standard in boiler efficiency, redundancy and reliability.
Each Array boiler utilizes multiple heat exchanger modules, providing high turndown and multiple boiler redundancy in one packaged unit.
A single Array boiler provides superior uptime reliability that is only found in larger boiler plants and multi boiler systems.
