KN family of boilers: KN-26
Joining the KN-16 as the latest addition to the growing family of the KN-Series boilers, the KN-26 produces 2,600,000 BTUs, while maintaining the features that have made the KN-Series boiler the most recognized appliance in the commercial boiler industry - long lasting durability and ultra-high condensing efficiencies all in a compact footprint.
The KN-26 puts the final piece into the most complete line of condensing boilers on the market. KN-Series boilers are built to meet the most challenging demands of today's condensing commercial boiler applications.
The KN-26 takes all of the successful attributes of the KN-30 boiler and incorporates them into a smaller size. The same tried and true system versatility and durability seen on all KN-Series boilers holds true for the KN-26. From single boiler applications to multiple boiler master/member networks controlled thru the HeatNet integrated control platform the KN-Series is the most versatile boiler for all types of applications including today's variable volume systems.
Premium efficiencies with high system turndown and low emissions make the KN-Series line of condensing cast-iron boilers the most cost effective option for every application.
- Factory piped & wired packaged boiler in a compact footprint; capable of being rigged via pallet jack through a standard doorway.
- Single field adjustment required: zero governor gas valve controls CO2 by a simple metric allen key setting.
- Variable water flow heat exchanger accepts up to 10:1 range, minimizing piping costs.
- Venting runs of up to 80 equivalent feet each, exhaust and air intake.
- Unrivaled heat retention: high mass cast iron heat exchanger with 5x the the wall thickness or copper holds heat energy longer.
- State of the art HeatNet integral control provides user-friendly Multi-function monitoring of all boiler operations with intuitive diagnostics and easy to read text displays.
- Down-fire design offers easy accessibility to all components for annual service and maintenance.
- 88% combustion efficiency a full input. 99% combustion efficiency at minimum input (5:1 turndown).
- Optimal fuel utilization and boiler performance thru integral HeatNet control module.
- Low NOx and CO2 emissions - Reduces greenhouse gases.
- Meets South Coast Air Quality Management Division (SCAQMD) Rule 1146.2 standards.
- Made in the USA
- Ultra efficient Tru-Flow symmetric air/fuel coupling design burns clean while insuring proper combustion at all firing rates.
- 5:1 continuous modulation for maximum efficiencies at all levels of heat demand.
- Proven 8,000 btu pilot or "mini burner" with interrupted spark ignition and air-cooled UV sensor for enhanced reliability.
- Low pressure drop thru the boiler does not require high velocities and allows good flow-balancing thru multiple boiler configurations with reverse-return piping.
