Hermetic rotary compressors use a rotating compression mechanism and an internal electric motor enclosed within a permanently sealed steel shell. Their compact size and relatively smooth operation make them common in room air conditioners, refrigeration equipment, heat pumps, and other HVAC/R applications.
DAC Worldwide’s Hermetic Rotary Compressor Cutaway (373-160) is an expertly sectioned example of a fractional-horsepower rotary-type refrigeration compressor. Both the sealed steel shell and internal compressor assembly are cut away, providing visibility into components that would normally be inaccessible.
The full-size industrial component supports practical training in rotary compressor construction, operating principles, component identification, HVAC/R system design, troubleshooting, and preventive maintenance.
Carefully planned cutaway areas reveal the internal motor, drive shaft, rotary compression assembly, refrigerant passages, and supporting components. Learners can examine how the internal motor drives the rotating mechanism to draw in, compress, and discharge refrigerant.
The cutaway also allows instructors to compare rotary compressor construction with reciprocating and scroll compressor designs. Selected components can be removed or disassembled for closer inspection.
Learners can use the cutaway to:
The cutaway is an instructional demonstration aid and is not intended for operational refrigeration-system use.
The compressor is cleaned, primed, professionally sectioned, and painted using a high-endurance urethane coating. Cutaway surfaces and selected components are color-coded to make internal geometry and operating relationships easier to recognize.
The component is mounted on a formed-steel, powder-coated baseplate assembly. It can be used for benchtop demonstrations or mounted on compatible DAC Worldwide display, storage, and workstation products.
