Electromagnetic valve: Used to control the on-off of the compressor's gas and oil circuits (such as intake valve control electromagnetic valve, sewage discharge electromagnetic valve, etc.), some models use 110V 50Hz AC power to ensure stable switching under the corresponding voltage and frequency.
Contactor / Relay: Key components in the electrical control system, used to control the start and stop of high-power components such as motors and heaters. Products of 110V 50Hz specification are suitable for compressor models with specific circuit designs.
Heater: Includes oil heater, environment heater, etc., operating through 110V 50Hz power supply, preventing lubricating oil from emulsifying when the compressor stops or making it difficult to start in low-temperature environments.
Sensor and instrument: Some pressure sensors, temperature sensors' power supply modules or accompanying display instruments may use 110V 50Hz power to ensure stable transmission and display of monitoring data.
Control board auxiliary components: Such as small fans, indicator lights and other auxiliary components in the control circuit, may be designed as 110V 50Hz specification.
