DAC Worldwide’s ACR Oil Separator Cutaway, Helical-Type (373-722) is a professionally sectioned example of a helical oil separator commonly used in commercial and industrial refrigeration systems.
Refrigeration compressors discharge a small amount of lubricating oil with the hot refrigerant vapor. An oil separator removes much of this entrained oil from the discharge gas and returns it to the compressor crankcase or an oil reservoir, helping maintain proper lubrication and reduce oil circulation through the system.
Typically installed in the compressor discharge line before the condenser, oil separators are especially useful in larger refrigeration systems, multi-compressor arrangements, low-temperature applications, and systems with long refrigerant piping runs.
Inside a helical oil separator, the refrigerant-and-oil mixture is directed through a spiral flow path. Centrifugal force moves oil droplets toward the separator wall, where they collect and drain into the lower portion of the vessel. The separated oil can then be returned to the compressor or oil reservoir.
A carefully planned cutaway exposes the separator shell, helical element, oil-collection area, oil-return components, and refrigerant-flow path. Color coding, directional-flow arrows, and numbered callouts make the separation and return process easier to visualize.
The ACR Oil Separator Cutaway, Helical-Type supports instruction in compressor lubrication, centrifugal separation, discharge-line components, oil management, preventive maintenance, and refrigeration-system troubleshooting.
The cutaway is mounted on a modular display panel for convenient classroom and laboratory use. It can be used independently with a compatible tabletop mounting foot or combined with other DAC Worldwide cutaways on optional display and storage frame assemblies.
The equipment is cleaned, primed, and finished with a durable urethane coating to withstand frequent use. Carefully selected cutaway areas expose the device’s internal components while preserving their relationship and operating principles.
Actual component brands and models may vary depending on availability.
Pair the Helical-Type ACR Oil Separator Cutaway with additional DAC Worldwide HVAC/R cutaways to compare oil-separation methods, compressor-protection components, refrigerant flow, and system applications.
