A full model line allows for application flexibility and meeting the needs of the space in
the most efficient way possible.

In-shot Burners on Each Heat
Exchanger Tube

ignition and extinction.

RAISE YOUR COMFORT LEVEL
When working indoors, you want to ensure you have plenty of fresh air to breathe. Modine’s
separated combustion Hot Dawg unit heater draws its combustion air from the outside to
ensure the air is clean to breathe. This fresh air supply reduces common concerns about
dusty, dirty, or humid applications. Additionally, by drawing the combustion air from
the outside, the overall heating efficiency increases. Check out the features below that
make Modine’s separated combustion Hot Dawg unit heater rise above the competition.
