PRODUCT FEATURES
All Greenheck model IGX-HV units feature 80%
efficient indirect gas-fired furnace(s), filtered
mixing box section, fan section, and are ETL listed
to the UL-1995 test standard. Heating capacities
range from 100,000 to 1,200,000 BTU/Hr and air
flow volumes are available up to 15,000 cfm.
A modular design concept enables the flexibility
to customize each product for its application. Modules
are then factory assembled and wired to minimize field
installation labor. The result is a semi-custom product at
an attractive cost.
Indirect Gas-Fired Furnaces
The Greenheck furnace is designed for top-notch
performance and long life, combining quality
components with expert craftsmanship. Unique to
our furnace is a post purge cycle, which runs the
combustion fan after the unit is shut down to vent
hot air and moisture out of
the heat exchanger. The
elimination of these corrosion
catalysts adds years to the
life of the heat exchanger.
Other key features of our
furnace are listed below:
• Power vented
• 80% thermal efficiency
• Seamless tubes
• Electronic staged gas controls
• Electronic modulating gas controls
• Aluminized steel or stainless steel heat exchanger
• Direct spark ignition system
• Easy access burner controls
• ETL listed to ANSI Standard Z83.8
• Solid state automatic ignition module
Vibration Isolators
The entire fan and
motor assembly is
mounted on vibration
isolators to minimize
noise transmission into
the building. Neoprene
isolators are standard on
all units, spring isolators
are optional.
Reliable Fan Performance
Air performance ratings from Greenheck’s AMCA
registered test chamber ensure accurate data.
Fans are constructed of heavy gauge steel and
designed for high efficiency
and low sound levels.
Wheels are statically and
dynamically balanced
to ensure vibration free
operation.
Control Center
The control center includes
the following standard components:
• Magnetic motor starter with solid state overload
protection
• Control transformer
• Disconnect switch
• Separately fused motor
• Distribution terminal strip
Premium grade control
components are selected for reliable operation. All
electrical components are UL Listed, recognized or
classified. Control centers are factory prewired for
single point power connection.
Factory Wired
and Tested
All units are tested
prior to shipment.
Units are checked for
