lubricant  oil.    In  addition,  Hanbell  also  offers  250W  oil  heater  to  keep  adequate  lubricant  oil  temperature  for  large  external  oil 

separator and applications in areas with low ambient temperature.   

Specification

：

  250W;    110V or 220V;    IP 54;    Outer diameter of cable: 6~8mm 

Note:   

1.

 

If compressor is installed in low ambient temperature, it is recommended to insulate oil separator against cold ambience. 

2.

 

The cable connector equipped with oil heater is part of certified explosion proof unit which is prohibited to be changed 

randomly. If it is required to be changed, it is necessary to use the spare part equal to oil heater cable specification and ATEX 

explosion proof standard or contact Hanbell sales representative. 

3.

 

The cable connector is required to be locked by wrench until it can’t be dismantled by manual, and should you require 

technical document for further clarification, please contact Hanbell sales representative. 

 

2.11 Oil level switch 

There are 2 wires for the interlock to main control circuit or any micro controller’s independent circuit. To prevent from oil level 

switch trip caused by oil foaming or surging in the sump, a time delay around 10 ~ 15 seconds is recommended before shut down 

the compressor. 

                                                                                         

Max. contact capacity = 50W/SPST 

Surge current = 0.5A 

Max. voltage = 200V DC/ 240V AC 

Max. current = 1A                                                                                                                                 

 

Note:   

1.

 

On the float ball there is a triangle mark which tells you its sensor direction. Therefore, before you install an oil level switch on 

a compressor or an external oil separator, please use the triangle mark as your reference before install any oil level switch on 

the compressor or external oil separator. 

2.

 

Please check this triangle mark and modify the oil level switch if needed.   

3.

 

If you have any other question, don’t hesitate to contact with Hanbell representatives for help. 

4.
