Siemens MVL661 EEV Valve

[Peter_1]

Which brand of controllers from the shelf can control these valves?
Carel and Dixell apparently can't.
Guess Eliwell can't neither.
Any suggestions?
We have a blown up PCB on a chiller - complete standstill now - and a new PCB is not ready available.
This is very urgent. Client has to rent now a chiller which will cost +/- 16.000 €/week (!!) and +/- 12.000 €(!!) to connect it.
Haven't found a Siemens controller neither.

The EEVs themselvs cannot be replaced with other brand for which there is a controller?

Searched too far, Siemens has their own Polycool controller. I will ask tomorrow morning where those are available.

Not sure, but maybe you can install new EEV Valve complete with belonging controller from Danfoss, Honeywell, Carel whatever is available on stock.

Hope this will give you some idea ... sorry cannot help more.

Best regards, Josip :)

That's the last option Josip because this is a much bigger and more expensive job then. If we should change, then I should go for Carel because we used those already in the past. Danfoss is another option.
The controllers of Siemens are costing +/- 350 €, just hoping now they're ready available.
