CONDENSER AND CABINET OPTIONS:
Condenser coil protection against corrosive environments is available by choosing any of
the following options. For additional application recommendations, refer to FORM 150.12-
ES1.
Post-Coated Condenser Coils – The unit is built with electrostatic post-coated condenser
coils. This is the choice for corrosive applications (with the exception of strong alkalies,
oxidizers and wet bromine, chlorine and fluorine in concentrations greater than 100 ppm).
Enclosure Panels (Unit) – Tamperproof enclosure panels prevent unauthorized access to
units. Enclosure panels can provide an aesthetically pleasing alternative to expensive fenc-
ing. Additionally, for proper head pressure control, Johnson Controls recommends the use
of Condenser Louvered Panels for winter applications where wind gusts may exceed five
miles per hour (8 kph). The following types of enclosure panels are available:
Wire Panels (Full Unit) – Consists of welded wire-mesh guards mounted on the exterior of
the unit. Prevents unauthorized access, yet provides free air flow.
Wire/Louvered Panels – Consists of welded wire-mesh panels on the bottom part of unit
and louvered panels on the condenser section of the unit.
Louvered Panels (Condenser Coil Only) – Louvered panels are mounted on the sides
and ends of the condenser coils for protection.
Louvered Panels (Full Unit) – Louvered panels surround the front, back, and sides of the
unit. They prevent unauthorized access and visually screen unit components. Unrestricted
air flow is permitted through generously sized louvered openings. This option is applicable
for any outdoor design ambient temperature up to 115°F (46°).
Coil End Hail Guard – Louvered panel attached to exposed coil end.
