Soft Start Included – Maximize Your System’s Efficiency
CTM Marine’s 48,000 BTU Marine Chiller System includes a Soft Start board that is self-optimizing, and reduces start up current by 65-75% of the compressor’s LRA (locked-rotor amperage). The Soft Start provides several benefits, including:
– Improves Compressor Performance: Soft starting reduces the initial current surge, which can improve the performance and extend the life of the compressor.
– Reduces Power Consumption: By gradually ramping up the voltage, a soft start reduces the peak power demand and can help reduce overall energy consumption.
– Enhanced Protection: Soft starting helps protect against overloading the electrical system, reducing the risk of damage to the electrical components and ensuring a safe and reliable operation.
– Improved Comfort: Soft starting can reduce the noise and vibrations associated with starting up a compressor, making the operation smoother and more comfortable.
