m. Oil heater
Oil heater is used to maintain the oil temperature in the oil separator during shutdown cycles. It can help to get a
safe start-up especially when the ambient temperature is low. Oil heater should be energized only when the
compressor unit is not in operation and should not be energized when there is no oil in the reservoir. The selection
of oil heater depends on total quantity of oil.
Before restart of compressor after shutdown for a long time, please turn on oil heater at least 8 hours to make the
temperature inside compressor higher than system temperature and ambient temperature and then it can prevent
condensation of refrigerant inside oil sump of compressor which may result in liquid compression in next start and
poor lubrication due to too low viscosity. In addition, Hanbell also offers 300W oil heater to keep adequate
lubricant temperature for large external oil separator and applications in areas with low ambient temperature.
Specification : 150W, 300W, 110V or 220V, IP 54, UL approval
150W , 300W oil heater
n. Mounting pad
To avoid extra vibration and noise resulted from direct contact between compressor footings and the base on
which compressor is mounted, it is recommended to add mounting pads in between as the drawing below shown.
