A customer of us has three chillers with brazed plate heatexchangers from an undisclosed company along with a few of ours. From one of the three chillers the evaporator has blown due to frost.

The supplier says they can deliver a new one by the end of July, machine went down last week!

Both compressors contain more water then oil so they also need to be replaced! They cost almost the same as 3/4 of a complete machine and can be delivered within 16 weeks from ordering!

Is this common?

We desided to use our one evaporator which is slightly larger in size, costs half and was delivered within 2 days.

Howcome a large company in chillers can't deliver an evaporator within the week?
