DL compressors
Compressor Overview
Technical specification
Many vehicles for transportation of goods or
recreation, such as trucks, caravans, boats, cars,
etc. are often equipped with cooling appliances.
These compressors are designed to operate
silently, efficiently and reliably even up to angles
of tilt of 30º, working with refrigerant R134a.
The compressors for such mobile applications
must be designed to operate from a low voltage
DC power supply. These compressors must also
be compact in their dimensions, highly reliable
and yield high performances.
The DL series of compressors are not designed for
off-road applications. Special approval is required
by Danfoss Commercial Compressors for this type
of application. The maximum tilt angle allowed in
DL compressors (stopped or running) is 30º.
DL19H, DL22H and DL30H are the answer to the
users’ needs requiring comfort and reliability in
their travelling, either on holidays, at work or in
any other circumstance where Direct current is
DL19H, DL22H and DL30H can be powered at any
voltage within the 12 to 24V DC range, and are
designed for capillary tube expansion.
