Refrigeration Oil Separator

HVAC Technician

Service Technician

The title denotes a field-based technical role responsible for servicing, maintaining, and troubleshooting rotary tillers — consistent with the widely recognized 'Service Technician' occupational category in agricultural engineering. Responsibilities (hydraulic checks, gearbox lubrication, tine replacement, calibration) confirm hands-on maintenance and operational support functions. While 'Rotary Tiller' is product-specific, the core role maps to the standardized 'Service Technician' with agricultural equipment specialization.

HVAC-R Technician

This is a formally recognized occupational title defined by the U.S. Bureau of Labor Statistics (BLS) with standardized duties directly applicable to air-cooled chillers—including installation, maintenance, troubleshooting, operation, and inspection. The role is not product-specific in naming (no 'chiller' or 'air-cooled' prefix), so product_specific_title = false; however, specialization in chiller systems is supported by BLS evidence citing growing demand for expertise in high-efficiency air-cooled systems.

Refrigeration Technician

Refrigeration Technician is a widely recognized, standardized occupational title in HVAC-R (Heating, Ventilation, Air Conditioning, and Refrigeration) engineering domains. The evidence confirms direct involvement with refrigeration system components—including oil separators—in industrial applications. While the role interacts with the product, the title itself is not product-specific (e.g., not 'Oil Separator Technician'), so canonical_role remains the standard industry term.
