Chillers for semicon

I work as technician in a Singapore semiconductor factory. Here I share my working life as technician.

There are several types of chillers in use in our plant.

The most popular is this blue color type, called Neslab Chiller

It has a upgraded version, also called Neslab but in white color, so we call it Neslab White. Just to differentiate the old and newer model:

Both Neslabs models is already obsolete, where the maker of the chillers not supporting the sparepart. So the market repairer need to source it somewhere and cause the repair cost at high side.

So actually there are few replacement for the obsolete issue, that is SMC chiller replacement. Its pump function very strong and temperature maintain is good. Just the problem in it is not integrate into machine alarm.

Talking about the neslab, the frequent failure in it is cant maintain at temperature setpoint, then you need to topup the refrigerant gas and make it chill down.

Hope you like my article about semicon industry in Singapore, and give me a thumb up if you find it useful and interesting. Thanks.
