Compressor
Compresses refrigerant gas, raising pressure and temperature to circulate through the system and remove heat effectively.

Expansion Valve
Sprays liquid refrigerant into the evaporator, causing rapid temperature drops needed for low-temperature testing.

Pressure Switch
Safety watchdog that monitors system pressure and cuts power to protect the compressor from damage.

Dry Filter
Removes moisture and debris from the refrigerant to maintain system efficiency and longevity.

AC Contactor & Switch
The electrical muscle that handles high-power electricity for motors and heaters based on controller signals.
