YORK YVWA Variable-Speed Screw Chiller vs PWMC / RWC Water-Cooled Chiller
Spec comparison for two products on Aviation Souk. Both compete in HVAC & Climate Systems.
HVAC & Climate Systems
YORK YVWA Variable-Speed Screw Chiller
by Johnson Controls | YORK
Variable-speed water-cooled screw chiller with 50% fewer moving parts than slide-valve competitors, offering continuous 12.5% turndown and up to 30% better real-world efficiency.
HVAC & Climate Systems
PWMC / RWC Water-Cooled Chiller
by Petra Engineering Industries
Modular water-cooled chiller from 10 to 70 TR per module with up to 16 modules combinable, offering incremental capacity expansion, N+1 redundancy, and optional heat-pump operation — suited to phased or mission-critical cooling builds.
