70% to passStandard filter/driers used in many commercial type refrigeration units may contain what type of substance?
Aactivated charcoal
Balcohol based liquid drying agents
Cactivated alumina or silica gel desiccant beads
Dall of the above may be used
AI Explanation
The correct answer is C) activated alumina or silica gel desiccant beads. Standard filter/driers used in many commercial refrigeration units typically contain activated alumina or silica gel desiccant beads. These materials are effective at absorbing and removing moisture from the refrigerant system, which helps prevent ice buildup and damage to the compressor and other components. Activated charcoal (option A) and alcohol-based liquid drying agents (option B) are not commonly used in these types of filter/driers.
