We have an 220 VAC solenoid at one of our McQuay Chillers. It is used as part of its expansion valve. We have been facing overheating issues for a while.
Please find below its specifications:
Type: BF230CS,
Code No: 018F6282 220/230 VAC,
10 W, 50/60 Hz,
Ambient Temperature: 50 deg C
Applied Voltage: 220 VAC
At 220 VAC supply voltage, it reaches 80 deg C during operation which is beyond its maximum temperature (> 50 deg C) tolerance as mentioned above. It reaches this temperature within 25 minutes of operation and the current shoots up to 129 mA.
We conducted a test to see if its response would be different at 110 VAC. At 110 VAC supply voltage, it operates at 30 deg C i.e. it stays within acceptable temperature limits and it operates at a current of 46 mA. It is operating as per requirement at this supply voltage.
We have two queries with regards to its operation:
* Can solenoids rated for 220 VAC operation be operated at 110 VAC? Will operating it at 110 VAC have any long term effects or impact in the long run?
* If the answer to the above question is no, kindly suggest a coil with a rated operating voltage of 110 VAC suitable for our requirement as part of expansion valve.
