R-Type Multi-Ton Condensing Units

With High Efficiency Compressors

Type R remote condensing units represent the next generation of seawater-cooled, reverse-cycle heat pumps for cooling and heating in marine applications.

Available in capacities from 20,000 to 48,000 BTU/hr. Models up to 36,000 BTU/hr use reciprocating compressors, while the 48,000 BTU/hr units use scroll compressors.

These condensing units can be installed with up to two Cruisair cooling units, where the total cooling unit capacity is equal to the condensing unit capacity. Some applications may allow three cooling units on one condenser; contact the Cruisair Applications department for assistance in design prior to installation.

In the cooling mode, full performance is available in seawater up to 90 degrees F (32 degrees C). In reverse-cycle heating, the unit will provide heat in seawater as low as 40 degrees F (4.4 degrees C).

Capacities (BTU/hr) 20,000 - 24,000 - 30,000 - 36,000 - 48,000
Voltages 230V/60Hz/1 or 3 Phase - 220V/50Hz/1 Phase - 380V/50Hz/3 Phase - 460V/60Hz/3 Phase
Reverse cycle for cooling and heating Yes
Cabin controls SMX, Qht, or Q3

  • Higher efficiency compressors at lower amperages.
  • Redesigned R type unit is lighter in weight.
  • Service ports on refrigerant lines and base valves.
  • Rubber isolation mounts on compressors.
  • Condensate pan with front and rear drains.
  • Corner mounting brackets designed for easy install.
  • High and low pressure switches.
  • Three different control options:
    1. R series uses a 3-knob rotary switch assembly.
    2. RX series includes an SMX II power/logic board and uses the new SMXht, SMXir or SMX II keypad/displays.
    3. RN series includes an SMX Net power/logic module.
  • Electrical box can be remotely mounted to deck or bulkhead up to 3'(1m) from unit.
  • Available with "green-gas" R-417A refrigerant.
  • Seawater coil manifolds are optional.
  • Heavy-duty vibration isolators are available.
