Cruisair EMB/EHMB Series Modulating Evaporators

High-Efficiency Cooling Units for RM Modulating Condensers

Call 561-586-0707 for pricing and availability


Cruisair modulating DX evaporators are ductable cooling only (EMB) or cooling with electric heating (EHMB) units with built-in refrigerant solenoid valves and high-efficiency blowers. Cruisair modulating air conditioning systems allow up to five independent temperature-controlled zones on one RM type modulating condensing unit (see spec sheet L–2366).

EMB and EHMB units are designed to be installed low in a closet or cabinet, with supply air ducted to grilles high in the cabin. Units are available in capacities from 4,000 to 16,000 BTU/hr. EMB models are cool only while EHMB feature electric heat with high-temperature insulation to meet ABYC requirements.

All metal surfaces over which air passes are covered with insulating foam to reduce secondary condensation and noise. The condensate pan has an anti-slosh, antifungal foam lining and rubber mounting feet for noise and vibration control as well as easy installation.

The high-efficiency blower can be rotated so the air can be discharged in different directions. The permanent split capacitor (PSC) motor is internal to the blower wheel and housing, which results in a quiet unit with excellent performance and speed control, especially when used with a Cruisair SMX series control.

An electrical junction box is included with the unit, and has a 3 ft. (1 m) wire harness so it can be mounted in an accessible location.

EMB and EHMB cooling units can be controlled locally with a mechanical switch assembly, SMX II microprocessor (SMX II power/logic box, control, and cables are sold separately), or the Q-Logic microprocessor system with Qht or Q3 display.

Remote monitoring via the central boat monitoring system or Cruisair’s Gateway network is possible with the Q-Logic control system and optional CAN-bus adapter board.
