Sentry Dual Tube Coils (DTC) are spirally wound, full
counter flow heat exchangers well suited for a
variety of applications where low flow rates of high
temperature and/or high pressure fluids need
cooling or heating. The sturdy tube within a tube
concept uses heav y duty terminal fittings to provide
for a plain tube end interface for the inner tube and a
compression connection for the outer tube. The plain
end of the inner tube is easily adapted to a variety of
connections including compression, threaded, socket
weld, sanitary clamp, etc. The tube within a tube design
also provides for high pressure/temperature capabilities
on both sides of the heat exchanger, giving greater
application flexibility. The single continuous inner tube
increases reliability and cleanliness and allows the unit
to be completely drainable.
