If You, Or Someone You Know, Is Looking To Start Their Boat's A/C Without Shore Power, or With Low Power, Read This:


SoftStart Marine™ Enables A Marine Chiller / Air Conditioner To Start And Run On A Small Generator, Or Limited Power When It Would Otherwise Not Have Started. Tired Of Being Sleepless On Hot Stuffy Nights? Now You Can Enjoy Your Boat's Chille / A.C. Using Only A Small Generator.

How It Works

SoftStart Marine™ temporarily reduces the load and torque in the electric current rush of the motor in the start-up. It uses a soft start ramp-up sequence that achieves a low start-up current. SoftStart Marine can deliver 65% to 75% start current decrease, as compared to a compressor’s locked-rotor amperage (LRA).SoftStart Marine is the ideal solution that enables a marine chiller / air conditioner to start and run on a generator, inverter, or limited shoreside power when it would otherwise not have started. This reduces the mechanical stress on the motor and on the attached power cables and electrical delivery network, extending the life of the system. Enjoy cool air conditioning using just a small generator and a  SoftStart Marine – while you are out and about. Don’t tie yourself down to shoreside hookups anymore.
