Safety interlocks stand up to use in demanding application

Ideal Heating has upgraded
safety procedures at its Hull
site with the introduction
of interlocking systems
from Castell. The heating
specialist has installed
safety switches and access
interlocks on ten machines
in its foundry blowing area.

The blowing area turns
out sand-based moulds for
casting heat exchangers
used in the company’s
boilers. Waste sand from
the production process
tended to clog up the
previous safety system, but
Castell’s heavy-duty KSE20
multi-key electrical
switches and AI access
interlocks have been
unaffected by the
demanding environment.
