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. 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.

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 required for cooling.

These compressors are designed to operate silently, efficiently and reliably even up to angles of tilt of 30º, working with refrigerant R134a.

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 can be powered at any voltage within the 12 to 24V DC range, and are designed for capillary tube expansion.
