What are the three classifications of recovery equipment?

The correct classification of recovery equipment is based on the pressure conditions under which the equipment operates. Recovery equipment is categorized into three classifications: very high pressure, high pressure, and low pressure.

Very high pressure recovery equipment is designed to handle refrigerants at pressures significantly above standard atmospheric levels, typically found in certain industrial applications. High pressure equipment operates under high pressure conditions but not as extreme as very high pressure equipment. Low pressure equipment is intended for refrigerants that operate at pressures below atmospheric pressure, such as some systems using refrigerants like R-11 or R-123.

Understanding these classifications is crucial for ensuring that the proper equipment is selected for different refrigerants, as each type must be handled with specific care to maintain safety and efficiency. These distinctions help technicians select the appropriate recovery equipment for the task at hand while ensuring compliance with safety regulations.

The other options do not accurately represent the classifications based on pressure but instead provide categories that focus on different aspects, such as efficiency or equipment type, which are not standard classifications for recovery equipment.
