Standard Straitube™ Heat Exchangers

Straitube Thrush Heat Exchangers are designed to give greater heat exchange efficiency. Free circulation in the shell and heaters reduces frictional resistance and pressure drop. Headers are removable. Straight copper tubes make cleaning easy. No acids or chemicals need be used. This is a decided advantage over other types of heaters in hard water territories. Whether the job is heating domestic water, hot water radiation as a converter, cooling or preheating liquids, Thrush Heat Exchangers will do the job well, do the work economically and efficiently.


The large sizes of Thrush Heat Exchangers, No 120 thru No. 380 are furnished with ASME and National Board Stamping and certificate. This construction is acceptable in all States having regulations based on ASME Unfired Pressure Vessel Code.
