[labnetwork] Harkris Chiller Quality issues

[Donghai Zhu]

Hello Patrick,

We have a Haskris chiller for EBL system that runs continuously.  The compressor failed after three or four years’ service. The cost of the repair is more than half of the price of the chiller due to urgent on site repair. I remember there was an issue in the design of the chiller. The local service company made a little modification on it.

Good Morning All,  We purchased all new Haskris chillers both large and small in late 2014 and since the start up in early 2015 have had numerous failures, all of my  pumps started to leak at the input shaft seal, replacement pumps form Haskris have started to leak as well.
The most problematic has been the large R0300 Haskris air cooled and now one of the compressors just failed and we have to get repaired out of our pocket.   I'm interested to know if anyone else has had similar issues with there Haskris chillers.
Thanks   Patrick
