Mobile Refrigeration in Buses

On long journeys, many buses sell cold drinks to their passengers, and the BD compressor is universal for all types of buses, as it is universal for 12 V and 24 V DC power supply. The BD1.4F-VSD.3, BD35F, BD35F-B and BD35K-B cover a capacity range from 20 W to 180 W. They are unsurpassed when it comes to tolerating changeable climatic conditions and vibrations under harsh road conditions.

A special version of the electronic unit adapts the capacity of the compressor automatically (AEO) to the actual load on the refrigeration system. The algorithm adjusts the speed of the compressor to achieve a running time of approximately 30 minutes. This is the most energy efficient way to operate the compressor.

The BD1.4F-VSD.3 and BD35F/BD35F-B/BD35K-B (with electronic unit 101N0242) offer an ECO function which adapt the speed of the compressor to an optimum level.

It has additional features such as fan speed control, built-in electronic thermostat, communication interface which makes programming the controller easy, without requiring resistors or extra wiring.

Ideal for refrigerator sizes up to 30–50 liters with freezer compartment. The compressors are controlled by an electronic unit including protection against overload and hazardous battery discharge.

The unit also features an internal voltage recorder as well as calibration to the applied voltage (compressor monitoring).

FeaturesBenefits
Low weightOnly 2.3 kg for the smallest BD compressor makes it easy to carry.
Small and compact60 % less volume on BD1.4F-VSD.3 compared to BD35F. Increase net volume of the box.
Silent operationThe owner can sleep close to the box without being disturbed by a noisy compressor.
High efficiency. Low current consumptionEnergy-saving. Less battery capacity needed to keep the goods cooled.
Variable speed/capacityEnergy savings. Adapts speed to cooling requirement.
Direct 12 V / 24 V DC power supplyThe same compressor can be used globally. One product covers the world.
Special designed BD for buses.BD35F-B and BD35K-B reduce any noise from the compressor to an absolute minimum even on very bumpy roads.
Electronic thermostatCost savings. No extra thermostat needed. Fewer components and failure modes.
Alarm & event logsMakes identifying errors fast and is easy to service. Reduced service costs.
Fan speed control 40 – 100 %. Start / stop delaysReducing noise. Fewer components, fewer costs, less wiring, fewer installation costs.
Advanced battery protection functionSafety. The battery will never be drained. Buses can be started safely every time.
Meets EMI standardsThe electronic unit meets automotive standards, and in most cases, no additional EMI filters are required.
