What type of frequencey inverters are you using if you need one?
We used a few times Danfoss (rather expensive) and Télémécanique (cheaper then Danfoss) and the last 3 times Taian T-verter (cheap, even very cheap)
For example: a 15 HP +/- 1.200 to 1.300 euro.

Fingers crossed, but we never had troubles with it.
Busy these days with installing a 3 x 15 HP Bitzer pack and 13 Goedhart evaporators (meat factory)
2 compressors of the 3 are frequency driven by Taian's, and controleld by an Omron PLC with a small HMI display.
2 independent Bitzers for the Freezer.
It's the 1st time we're doing this with piston compressors.
Murco ***** alarm with 4 sniffers.
I will make some pictures of it next week.
Start-up is foreseen end next week.
