Cooling in Maritime Appliances

The BD compressor series is specially designed for refrigeration in boat applications. A sturdy design enables it to resist vibrations, hard impacts, and heavy seas.

The compressors cover a capacity range from 20 to 180 Watt. Low and medium back-pressure applications. Refrigerator sizes up to 180 liters and freezers up to 90 liters.

It is possible to adjust the capacity of the compressor manually. A special version of the electronic unit will adapt the capacity of the compressor automatically (AEO) to the actual load on the refrigeration system. The algorithm will adjust the speed of the compressor so that a running time of approximately 30 minutes is achieved. This is the most energy-efficient way to operate the compressor. The BD1.4F-VSD and BD35F/BD50F (with the second-generation electronic unit 101N0212) offer an ECO function which optimally adapts the compressor's speed.

Furthermore, these functions will protect the compressor from short cycling in low load situations and it will also reduce the number of starts and thereby protect the battery from being drained. An optional LED (diode) will flash and the following faults will be indicated by means of a flash pattern: low battery voltage, fan overload, minimum speed exceeded, thermal cutout, motor start error.

The new BD1.4F-VSD has additional features such as a fan speed control, built-in electronic thermostat, communication interface which makes programming of the controller easy, no resistors, and extra wiring. The electronic unit provides protection against electromagnetic interference (EMI ) which will allow communication and navigation equipment to work unproblematically without any disturbance.
