Construction
Rebel Applied rooftop systems introduce rooftop market in
cabinet construction by providing.
•
Nominal unit cooling capacities from 30 to 52 tons
•
Pre-painted exterior surfaces that withstand a minimum
1000 hour salt spray test per ASTM B117 to provide
longevity and prevent excessive corrosion
•
Double-wall foam injected panel construction for all
cabinet walls, access doors, and roof and floor panels
with solid steel liners and a thermal resistance of R-13
•
All Access doors are mounted with a durable full length
stainless steel piano style hinge

Air Leakage and Thermal
Performance
All panels are constructed with an integral thermal break to
eliminate all direct conductive heat transfer paths through the
panel which prevents energy losses and exterior condensation.
Through metal provides a path for heat to enter the cabinet and
lowers the effective R-value of the insulation. Figure 2 shows a
foam panel with R-8 insulation and 1% through metal performs
like an R-6 thermally broken panel.
Figure 4: Thermal Break
Rebel Applied offers the industry’s first low leakage packaged
rooftop cabinet and is tested in accordance with ASHRAE
Standard 111 with a rating of Class 6 air leakage at +/- 5"
of static pressure or 0.5% of supply air flow up 5" of static
pressure. Most new applied rooftop equipment operates with
leakage rates >3% at 5" of static pressure; Aging applied
systems leakage can approach leakage rates as high as
5-10% of the supply cfm. Light commercial rooftops typically
operating at lower pressures (3" or less) and see air leakage
rates in excess of 5% in most applications.

NOTE:
These leak rates are based on a 50 ton unit at 350
cfm/ton with economizer and gas heat
