Ultra-Low NOx Emissions
• Complies with SCAQMD 1146.2 NOx emission
requirements of 14 ng/J or 20 PPM.
Maximum Flow Rates up to 10.0 GPM
Heat Exchanger
• Primary heat exchanger of the ATI/ATO-540 is
constructed of a commercial-grade copper that is
more resilient to erosion. Copper is 25x better at
heat transfer than stainless steel thus stabilizing
outgoing water temperature quicker and reducing
pressure drop across the heat exchanger.
• Secondary heat exchanger is made of marine-
grade 316L stainless steel to protect against
corrosion.
Indoor Models
• Include integrated temperature controls and
advanced diagnostics to simplify troubleshooting.
• Include factory-installed power cords
Outdoor Models
• Include a wall mount temperature remote
controller and advanced diagnostics to simplify
troubleshooting.
