research and production processes, maintaining a controlled environment is
crucial. Process cooling equipment can help to regulate the temperature and
humidity levels in the production area. This ensures stable process conditions
and minimises the impact of ambient variations on material properties or
process stability.
Recirculating Chillers
Recirculating chillers are
widely employed in advanced metals research and production. These
self-contained units circulate a heat transfer fluid to remove heat from the
process. Recirculating chillers offer several benefits in advanced metals
research and production, including:
