Reinforced Risers - To strengthen the joint between the riser
and element junction box. Gussets are welded or silver soldered
to the box and riser to provide this reinforcement.

process tank, preventing damage to electrical connections due
to evaporation. Longer arms are available at a nominal additional
charge.

from wash downs, splashing and dripping. Standard on
all heaters.

assembly.
