Frequently Asked Questions
What refrigerant is compatible with the BD50F compressor?
The unit uses R134a as its specified refrigerant.
How does the fan cooling status affect operation?
Fan cooling (F) depends on application and speed. If it's necessary, a 3.0 m/s airflow is required for proper function.
What are the cut-in and cut-out voltage settings for a 12V or 24V system?
For 12V DC, they are 10.4 V (cut out) and 11.7 V (cut in); for 24V DC, they are 22.8 V (cut out) and 24.2 V (cut in).
Is static cooling usually sufficient?
Static cooling is normally sufficient, as indicated by 'S'. However, more intensive conditions may require oil or fan cooling.
