FlexPack™ was designed for energy savings, reduced installation

time and expense, and a better return on your investment.

Cabinet & Construction

The industrial grade cabinet is constructed of heavy gauge painted steel. The top and sides of the unit can be easily removed for convenient access to electrical and mechanical components. The unit also has a rooftop AC- style appearance to simply blend into the existing environment along with flush mounted fans for a sleek look. In addition, the unit has a clean and intuitive electrical and piping layout.

The unit was designed for 100°F ambient operation. It can be configured for higher ambient applications. The units are also Beacon II™ capable and were designed with state-of-the-art energy efficient motors.

■ Single unit to place on roof reduces installation cost

■ Small footprint requires less room on the roof or in the back of the store

■ Single-point wiring and piping lowers installation cost and provides a single penetration point through the roof

■ Significantly reduces air conditioning energy costs by reducing the heat load in the space through the use of remote condenser circuits

■ Quieter sound with fewer condenser fans and the reduced noise level of vertical fans

System Features

■ Up to 3 compressors, 1/2 - 6 HP Hermetic or Scroll®

■ RST, CF, CS, ZF, ZS standard compressors

■ 230 volt/1-phase/60 hertz and 230 volt/3-phase/60 hertz units available

■ 1, 2 or 3 condenser fan configurations

■ R-404A for medium or low temperature applications

■ Remote condenser circuits for ice machine, drink dispenser, display cases and more

■ Capacity range

l 1 Fan = 6 HP (up to 2.5 to 3 HP per side)

l 2 Fan = 12 HP (up to 5 to 6 HP per side)

l 3 Fan = 18 HP (up to 6 to 7.5 HP per side)

■ Electrical component layout lines up with compressor module

■ Beacon II™ or conventional mechanical controls available

■ Energy efficient, flush mounted 18" fans with 1100 RPM motors

■ Painted steel cabinet

■ Aluminum fin coils are standard; copper fin coils and polyester coated coils are optional

■ Convenient hinged access panels for easy access

■ UL listed for US and Canada
