Frequently Asked Questions
What parameters are needed when selecting this semi sealed compressor?
Model selection requires confirming required cooling capacity, operating evaporating and condensing temperatures, refrigerant type, power supply voltage/frequency, and application details.
How does the motor protection module function on model SP4H3000?
The built-in INT69B2 module continuously monitors motor winding temperature to prevent damage caused by thermal overload or severe operating conditions.
What routine inspections should operators perform during regular maintenance?
Regularly check the oil level through the sight glass, verify crankcase heater operation before cold starts, monitor operating current, and inspect internal filter cleanliness.
How does the rotatable valve design assist during installation?
Both suction and discharge shut-off valves rotate 360°, allowing installers to adjust line directions freely and reduce piping stress in tight mechanical spaces.
