Where does the need for scroll compressor soft starters come from?

Scroll compressors have earned a strong reputation in HVAC applications by proving to be a more reliable and efficient solution than other categories of compressors.

Scroll compressors are generally 10 to 15% more efficient than piston compressors. Worldwide initiatives promoting energy efficiency in the building sector are generating a growing interest for more cost saving and efficient HVAC solutions, making the use of scroll compressors more and more a necessity.

Scroll compressor high starting currents Benefits of soft starting solutions

Starting scroll compressors via direct on line (DOL) methods Carlo Gavazzi’s line of dedicated scroll compressor soft results in a high inrush current typically 6 to 8 times the rated starters RSBS, RSBD and RSBT is the result of an extensive compressor current. study of scroll compressor systems together with a continuous communication with our customers. Such levels of current inevitably cause a number of undesirable effects including: RSBS, RSBD and RSBT soft starters are equipped with specific algorithms to reduce the high starting currents thereby • Light flickering resulting in: • Triggering of protection equipment • Elimination of light flickering • Increased compressor noise and vibration • Reduction in voltage disturbances • Excessive stresses on compressor • Increased compressor lifetime • Voltage fluctuations and disturbances on neighboring equipment Additionally, by limiting starting current to more than 50%* with respect to DOL start, additional benefits can be achieved such as: • Lower-rating protection devices and cabling • Less expensive contracts with utility companies
