Optimize your building with the
latest gas-fired infrared technology
• Electronically Commutated Motor [ECM]
• Provides +85% radiant eciencies throughout a full range of operation, in addition
to whisper-quiet operation.
• An EC Motor is 2x more ecient than a PSC motor [Permanent Split Capacitor]
and 3x more ecient than a Shaded Pole AC motor which is commonly used
for infrared tube heaters.
• A constant torque EC Motor leads into more robust and stable combustion
through the heaters’ entire range of operation and external pressure changes.
Rinnai uses EC Motors across the complete HE+ product line of
single-stage, two-stage, and modulating infrared tube heaters.

True Modulating Models
• The custom control board provides real-time
optimization of fuel to air ratio for the
perfect combustion through communicating
with EC Motor and modulating gas valve.
• Eliminates temperature swings by pairing
ECM technology with gas valves.
• The heating system’s service life significantly
increases as frequent ON/OFF cycles [cold
starts] are reduced.
• Adapt the heat demand in the space to maintain
a consistent comfort level by truly modulating
the heat.
Optimized Reflector
• The new reflector geometry provides
increased eciency over conventional
reflectors and maximizes the heat distribution
throughout the entire radiant area.
• A reduced air gap on the top of the tube
heater results in less convection heat loss.
• Providing a more uniform heat distribution
across the same heating surface.
The EC Motor Blower includes
impeller, motor, and control
board all in 1 unit.
