Thrush Heat Exchangers are efficient heat exchangers and have a number of uses on many
different types of applications. One of the more common uses is the application to automatic dish
and glass washing machines. Thrush Heat Exchangers are constructed of steel shells and heavy
cast iron heads, with straight copper tubes for fast heat transfer. The liquid being heated passes
back and forth 4 times through straight copper tubes resulting in instantaneous heating.
REMOVABLE HEADS - EASY TO CLEAN
Thrush Heat Exchangers are easily cleaned, whenever cleaning is necessary. Removable heads
makes visual inspection possible. No acids are needed if tubes require cleaning. Where soft
water or water with low percentage of mineral deposits is used, it should only be necessary to clean
heater tubes every twelve to eightenn months. For easy cleaning, gate valves should be installed in
the supply and return lines from heater to storage tank with a union in each line between gate
valves and heater.
Cleaning Direction: Close gate valves in supply and return from heater to tank. Open unions
between gate valves and heater. Both heater heads can then be removed without the loss of any
water. After heads are removed, the straight copper tubes are exposed to view and can be cleaned
if necessary. Heads should be cleaned and heater reassembled with new gaskets.
The heaters are constructed in three pieces. The shell into which the straight seamless copper
tubes are fitted; second, the rear head and third, the flow head having two tappings for tank
connections. Heads are bolted to the shell and are sealed against leaks by heavy gaskets. Inlet
and outlet at opposite ends of shell assure uniform steam distribution.
