Introduction
Schwärnmle cooling water coolers
are low-cost industrial coolers with
very high operational reliability, fast
amortization and high performance.
Schwämmle cooling water coolers
can be used in all applications requiring heat exchange or temperature
stabilization, e.g. with precision
machine tools, lasers, plasmaarc
cutting machines, induction
machines, welding machines, degreasers, for emulsion cooling, etc.
