12450 Compressor unit

The DRALLIM Compressor Desiccator Unit 12450 (CDU 3C) is an energy saving integrated unit for supplying dry air to pressurised cables. It has been designed to alleviate the need for gas bottles in smaller exchanges, and the low dB rating allows the unit to be safely sited in manned areas. The CDU 3C consists of a small cabinet housing the compressor, desiccator, humidity detector and all electrical and pneumatic control circuits. An air receiver forms an integral part of the unit. The CDU 3C can be installed to be either wall or rack mounted using its alternative bracket positions or can equally be sited as a floor standing unit if preferred.
