THE ORIGINAL BOILER CONTINUES TO SET THE STANDARD
In 1986, Power-Fin® redefined the industry with its space-saving design, groundbreaking efficiency, and venting flexibility. Now, over 30 years later, we continue to raise the standard with an easy-to-operate touchscreen user interface, remote boiler control, and enhanced communications. The advanced Smart Touch™ color display includes CON•X•US® remote connectivity via WiFi or Ethernet for easy control at your fingertips, from anywhere. A simple drop-in Modbus or BACnet card allows for easy integration into a Building Management System.
ENHANCED OPERATING CONTROL
The Power-Fin now offers the industry-best Smart Touch™ 8˝ LCD full-color
touchscreen with easy-to-understand infographics. It is equipped with
CON·X·US® connectivity that lets you remotely monitor and optimize the
performance of the entire boiler plant.
- Starting with the introduction of the Power-Fin product line in 1986, we were able to provide something that other companies weren’t focused on, efficiency and footprint.
BURNER MODULATION BOOSTS EFFICIENCY AND LOWERS COSTS
With thermal efficiencies of up to 87%, Power-Fin boilers feature a 5:1 turndown ratio that will precisely match the firing rate to heating load requirements—at any point from 20% to full firing rate. This results in less equipment cycling for greater efficiency and cost savings.
READY FOR OUTDOOR INSTALLATION
In warm-weather sites where the mechanical room is overcrowded, the Power-Fin
can be easily installed either outdoors or on a rooftop. The outdoor hood and
screen protector make outdoor installation fast and trouble-free.
VENTING SOLUTIONS
The Power-Fin offers seven venting options for ease of installation and
flexibility to meet the most challenging installation requirements. The Power-
Fin permits air intake and exhaust terminations to be horizontal through a
sidewall or vertical through a roof. Consult the installation and operation
manual for detailed venting guidelines.

PEACE OF MIND, WHEN IT MATTERS MOST
Cascade Redundancy provides peace of mind because it helps ensure that a Power-Fin boiler system will always deliver reliable performance with no downtime. If the lead boiler is turned off for maintenance,Cascade Redundancy automatically shifts the lead role to the second sequenced boiler. Up to eight Power-Fin boilers can be sequenced using a 2-wire daisy-chain connection. Cascade sequencing can be programmed for Lead-Lag or Efficiency Optimized operation. With Lead-Lag operation, one lead boiler modulates to capacity on demand. As load increases, the system then cascades to additional lag boilers in sequence. The first-on role shifts daily, distributing equal run times to each unit. In an Efficiency Optimized system (see illustration left), all boilers fire and modulate simultaneously at the same Btu/hr input rates.
