Danfoss has introduced the third-generation VZH Variable-Speed Scroll Compressors. The third-generation commercial inverter scrolls retain the strengths of the previous version, with the addition of the Intermediate Discharge Valve (IDV) technology for enhanced seasonal efficiency, and a wider operating map. The products are particularly suitable for comfort reversible applications and computer room air conditioning (CRAC) units. Features and benefits of the new  scrolls include accurate temperature control and humidity management for high energy efficiency and comfort, a low start-up current, and a manageable acoustic level with variable speed technology.
