The condensing boilers in the Modulex line have modulating capabilities from 6:1 to 23:1, depending on the unit. Available in six sizes, the light commercial boilers have unmatched turndown to maximize seasonal efficiency and bring an unprecedented level of operating reliability to installations that require 300,000 to 1 million Btuh capacity, according to the manufacturer. The units have an operating noise level of less than 50 dBa and an NOx emission of less than 30 ppm. Each boiler combines between two and seven independent, 151,500-Btuh, pre-assembled thermal modules housed in a common enclosure. Each module has its own dedicated control with a combustion safeguard, variable-speed fan, modulating gas valve, electronic ignition, modulating burner, flow temperature sensor, thermostat, and heat exchanger. All individual thermal controllers are linked in a slave-to-master relationship with the boiler's master controller. The master controller drives or bypasses one or more thermal modules based in response to system load and the operating feedback received from each thermal module control. The boilers can support low gas pressure applications and PVC venting materials. Each unit has multiple supply/return piping, venting, and gas connection locations for even greater installation flexibility.
