Accessories

Accessories are factory furnished or optionally field furnished to provide the design engineer with the flexibility of selection and configuration he will require. Special factory built configurations other than the standard options shown, (direct evaporative equipment, fans, plenums, coil sections, filter sections, and supply air packages) may be furnished upon request. Direct evaporative units may be tailored to meet the coil units and cabinet fans. The design engineer can set the criteria ... equipment configuration can be his needs.

• Indirect unit, side mounted, secondary plenums and horizontal fans.
• Parallel indirect units mounted on a common base with an intermediate secondary plenum and top discharge fans.
• A 12", cooling only, insulated connecting duct section (indirect to direct unit).
• An insulated economizer connecting duct section consisting of the return air damper, outside air damper , damper actuator connecting duct-section and 2" filters.
• Cooling or heating coils are optional in the connection duct section.
• Factory mounting of the indirect unit, direct unit and connection duct section on a common 6" channel base.
• Factory mounted inlet louvers on the secondary side of the indirect unit.
• Screened inlet cowls for field installation on the primary side of the indirect unit.  
• Factory furnished supply fan sections complete with motors and starters and system controls.
• Factory supplied solenoid drain valves with freeze protection

These factory options provide the design flexibility to achieve , either field bolt together systems or factory furnished packages (on a common base of 2000 CFM) to 20,000 CFM capacity.
