APX Air-Cooled Chiller vs PWMC / RWC Water-Cooled Chiller
Spec comparison for two products on Aviation Souk. Both compete in HVAC & Climate Systems.
HVAC & Climate Systems
APX Air-Cooled Chiller
by Petra Engineering Industries
Mid-range air-cooled chiller with semi-hermetic reciprocating compressors, covering 35–460 TR across 50 Hz and 60 Hz markets for commercial cooling in space-constrained rooftop applications.
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.
