Cooling in trucks
Application Note
Most truck drivers are on the road for many days at a time. To keep
their food and beverages cold they need refrigerators that can be
built into the cab.
The BD 35F and BD 50 F compressors are tailored for the driving
workplaces. They are universal for 12 and 24 V DC power supply.
Besides they are unsurpassed to tolerate changeable climatic
conditions and vibrations under harsh road conditions all over the
world.
The BD 35F and BD 50 F compressors can be used for both refrige-
rators and freezers and use R134a as refrigerant.
The compressors are controlled by an electronic unit including
protection against overload and destructive battery discharge. The
unit also features an internal voltage recording as well as calibra-
tion to the applied voltage (compressor monitoring).
Important features:
• Efcient and reliable operation under extreme conditions
• High efciency/Low current consumption/high COP
• Compact design
• Silent operation, barely perceptible
• Variable capacity (manually adjustable or automatic)
The compressors cover a capacity range from 20 to 180 W.
Low, medium and high back pressure applications.
(See specication sheet on the next page).
Refrigerator sizes up to 160 liters and freezers up to 90 liters.
REFRIGERATION AND
AIR CONDITIONING
More than 25 years of experience with 12-24 V DC compressors
The BD 35F and BD 50F compressors are approved according to
the e4 automotive EMC standard and complies with the CE, UL and
C-tick standards.
