The P13H025A-BLDC-SH oil-free scroll refrigeration compressor is designed to support advanced environmental control systems in aerospace and military applications.

Environmental Control Systems (ECS) regulate sensitive electronics cooling, bleed air control, cabin pressure, and auxiliary systems in modern defense and civilian aircraft. Most systems use complex distributed rotary-vane and screw compressors that are constrained by intricate duct systems that compromise size, weight, and power. The P13H025A-BLDC-SH represents a compact and lightweight alternative with a superior coefficient of performance.

While traditional oil-lubricated scroll compressors use an Oldham ring to fix the orbital motion of one scroll relative to the other, the P13H025A-BLDC-SH uses idler shafts to maintain a tight running clearance between the precision-machined scrolls, allowing for efficient operation without the need for any lubrication. The design also uses a patented semi-hermetic configuration for compatibility with various refrigerants.
