Profile: AER Supply Ltd. is a provider of marine products. Our products include variable speed drive, variable frequency drive, air handlers, composite drain pan, sea water pumps, air grilles, gasoline engine, diesel engines, air conditioning equipment, refrigeration equipment, generators, pumps, trusters and water makers. Our variable speed drive is a micro-processor-based fan speed controller which is designed to reduce blower noise, especially when operating at slow speeds. Our variable frequency drive eliminates the large starting inrush current of the compressor by ramping up voltage and frequency in a controlled time period. Our Vetus drive system features a variable and adjustable piston pump, which operates according to the constant pressure principle. This type of pump continuously varies its output to provide the ideal balance between the required flow rate and the maximum operating pressure.
