Designed for hydronic heating systems, the Modulex EXT Boiler Series can be installed in a variety of light commercial and commercial applications. The units operate from 321-1,123 MBtuh and have turndowns of up to 24.5:1, for fuel savings, operating reliability, and installation flexibility. The boiler’s design incorporates multiple high-capacity, low-emission burners. Each 160,500-Btuh thermal module operates independently to increase turndown range, and the simultaneous low-fire-operation design helps maximize operating efficiency. The Modulex EXT Series features up to 99 percent efficiency. The Modulex EXT establishes built-in redundancy for uptime reliability. Multiple supply/return piping, gas piping, and venting locations allow units to be installed in almost any configuration. Venting can be accomplished with a variety of materials including PVC/cPVC, polypropylene, or stainless steel to the right, left, or rear of the boiler. It also has simple supply and return connections that are attached with four-bolt flanges, so the water and gas connections of a unit can be changed from one side to another in no more than 15 minutes, said the company. Units can be integrated via Modbus communications protocol to a facility-wide energy management system or building automation system (BAS).
