Downow air discharge, high velocity heater for high
bay applications
Model LDAP can provide more heat than a standard unit heater, up
to 1,200,000 BTUH. This is the same amount of heat as a typical
packaged heater or direct red unit.
Model LDAP is less expensive to install than a direct or indirect red,
packaged heating system.
By destratifying you lower the air temperature at the ceiling, and
reduce the heat loss in your building.
● Saves Money
» 83% Thermal efciency
» Destratication adjustable fan control (air economizer)
» Single point connections for gas, electricity and vent
● Sturdy - Patented

single burner combustion system
● Dependable - Titanium stabilized heat exchanger(s)
● Quiet - Vibration/noise isolated fan and venter motors
● Versatile
» Natural gas or propane
» Wall or ceiling mounting
» Run the fans without the heat in summer to improve working
conditions by alleviating stagnant air to create a cooling affect
» Directional nozzles and louvers aim the heated air right where
you need it (see photo below)

Step 1: Wall mounted thermostat calls for heat. Step 2: Burners and high speed fans direct
heating to the oor.
Step 3: Thermostat setting is reached, shutting
off heater. Heated air naturally rises.
Step 4: Unit mounted sensor triggers the low
speed fans to return heat to the oor.
Model LDAP is arranged for vertical (downow) air delivery. As
George Reznor once said, “We live on the oor, not on the ceiling.”
