Product features:
Type demonstration
"C"：marine
"L"：self-contained AC unit
"D"：electric heater, without "D" only cooling
"B"："low noise"
"20"： nominal cooling capacity is10*1000kcal/h
Main components
it is mainly composed of hermetic refrigeration compressor, horizontal shell and tube type condenser, evaporator, air filter, expansion valve, marine low noise centrifugal fan, electric heater (cooling unit without this), dry filter, pipeline and other control elements, instrument panel, electric control unit, all parts are installed in a casing.
Functions
The main functions of marine low noise cabinet AC unit is to conduct cooling and dehumidification in summer, heating in winter and ventilation in middle seasons.
Advantages
Marine low noise self-contained AC unit sets all functional components in one; all sheet metal parts adopt the mold production, branch parts manufacturing, the whole assembly, convenient installation and repair, the whole series products parts have strong interchangeability. It has the advantages of convenient and simple operation, compact structure, low energy consumption, low noise, shock and swing resistance, convenient maintenance etc. The design, manufacture, delivery of AC unit is conducted according to the standard of classification societies (such as "CCS", "ABS", "NK", "DNV") and "navy", and it can be manufactured according to customer's actual demands.
