DX SELF-CONTAINED

Cooling & Heating Comfort Systems

 

  • StowAway Units (Water Cooled)

    Self-Contained systems are ideal for smaller boats in which engine room space is limited. All of the system components, except for the seawater pump and strainer, are built on a single low-profile chassis. It is normally installed under a berth, in a closet or any other out-of-the-way location. Air is carried through flexible ducts to air grills for discharge into one or more compartments. StowAway systems are easy to install in an existing boat, since the unit doesn't take up much space and it can be installed without disrupting the boat's interior. The system's closed refrigerant loop is precharged at the factory, and no field charging is needed. A pre-wired plug makes for easy, error-free electrical hookup. StowAways are available in 5,000-24,000 BTU capacities.

    Remote - Split Systems (Water Cooled)

    Cruisair remote systems provide the greatest flexibility for boats 36 feet and up. The condensing unit, which includes the compressor and other mechanical components, is placed in the engine room. Only the compact, quiet cooling/heating unit goes in the living compartment, where it is normally built into the cabinet work. Cruisair offers a broad range of cooing/heating units for installation behind bulkheads, under bunks, in narrow lockers, beneath a fly bridge and other locations. You can run several cooling/heating units from a single remote condensing unit.

    Features
  • Condensing units located in engine room, with quiet-running cooling/heating units in living spaces
  • All systems reverse-cycle for heating and cooling
  • Available in 4,000 through 48,000
  • For operation on 115 or 230 VAC, 60 or 50 Hz (440 VAC and three-phase power on special order)
  • Works with SMX Series or other Cruisair controls
  • Wide selection of cooling/heating units for direct discharge or ducted air
  • Split systems use multiple cooling/heating units with a single condensing unit for maximum flexibility

    SMX II Controls For Direct Expansion Air Conditioning Systems

     

    The SMX II is a microprocessor-based electronic control for use with Cruisair direct expansion air conditioning systems. It can be retrofitted in the field to replace any electromechanical switch assembly.

    The SMX II has a non-corrosive ABS cover and soft-touch membrane switches. All keys are clearly labeled, making operation simple. The large, easy-to-read digital display shows set point or cabin temperature and also is used to give information on operating parameters and fault code warnings. Small LED's are used to indicate system status. Switch plates, which are available in black, brown, white or beige, must be ordered separately.

    For normal operation, it is only necessary to turn the system on and select the desired set point. The user can select cooling only, heating only, or automatic changeover between cooling and heating. Fan speed is automatically controlled, or can be manually set. Factory settings may be changed, with user-programmable commands, permitting the boat owner to fine-tune the system for personal preferences. Programming modes are accessed by pressing special combinations of keys.

    Programmable features Include AC line voltage calibration, temperature calibration, compressor restart time delay, continuous or intermittent fan operation, low and high fan speed adjustment, compressor response differential, Fahrenheit or Celsius temperature display The system's nonvolatile memory retains all user-programmed settings, even when the power is switched off.

    The SMX II constantly monitors line voltage and refrigerant pressures. Whenever out-of-tolerance conditions are sensed, the SMX II computer displays a visual warning and shuts the system down to prevent damage.

    Software upgrades for the SMX series controls are released periodically by Cruisair, and new software can be installed in the field by exchanging plug-in EPROM's.

    The dehumidification program ensures, even when no one is aboard, the boat stays dry, eliminating mold, mildew and odor.

    Rotary Switch Assemblies

    Rotary Switch Assemblies For Direct Expansion (DX) Air Conditioning Systems

     

    Cruisair electromechanical rotary-knob switch assemblies provide reliable positive control over basic air conditioning functions. The standard switch assembly contains three knobs for controlling the thermostat, fan speed and function selections (OFF-FAN-RUN). Variable or two-speed fan controls are available for either type of blower motor.

    Single knob switches are used to provide fan control when two or more cooling units are linked to a single remote condensing unit. Two-knob switches are used with SMX-series "slave" installations to provide fan operation independent from master control.

    Standard switch plate colors are brown and black. Vertical and horizontal switch plates are available in three knob versions. A ten-foot length of capillary tube, with thermostat bulb and anticipator, is standard on SA3 and SSA3 types.

    Cruisair switch assemblies are available for 115V or 230V systems.
