How to choose water recirculating chillers?
Several analytical instruments use water recirculating chiller to maintain their process temperatures, the effective thermoregulation is done by recirculating water.
A recirculating chiller is a form of enclosed, high-efficiency cooling system. Their major role is to remove heat by circulating cold water and maintenance temperature as per attached instrument. Most recirculating chillers can work in temperatures ranging from 12 to 30 degree which is adjustable.
Let’s discuss some common issues which damage critical component like pump and compressor.
Dry run off Chiller
1. Insufficient fluid in reservoir
This happens when there is Insufficient fluid in reservoir due to which there is low water flow and leads to damage of pump and compressor.
2. Blocked fluid filter
When dust particles or contaminants in the water clog the filter, no pumping or water flow occurs.
3. No fluid in pump cavity
This happens when there is air in pump cavity due to the leakage in pipe. Such issues damage critical components and increase system downtime with heavy maintenance cost to run the system.
When such criteria are ignored, chiller selection becomes more difficult. This is where HEXON INSTRUMENTS research and studies come in handy to help find a solution.
