Electrical systems need to perform consistently in
boiler rooms and around furnaces and evaporators.
Many of these processes require heat tracing to
maintain elevated temperatures throughout water/
wastewater processing systems.
Excessive heat or cold can wreak havoc on an electrical
system, potentially causing critical components to fail.
Operations are challenged to:
r Prevent premature material aging due to prolonged heat
r Avoid material contraction and expansion due to ground frost
r Protect against physical damage from hail
Thomas & Betts offers numerous electrical systems
and devices that are designed to withstand and
insulate against severe temperatures.
