Catalog excerpts

Heat Exchangers Solid & Powder Steam & Water Sentry® DTC-4 (dual tube coil) tube-in-tube heat exchangers 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. MODELS DTC-CUA/CUA-4-1-1 DTC-SSA/CUA-4-1-1 DTC-IN1/CUA-4-1-1 DTC-SSA/SSB-4-1-1 DTC-IN1/SSB-4-1-1 BENEFITS The sturdy tube-within-a-tube concept uses heavy 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 and many more. The tube-within-a-tube design also provides for high pressure/temperature capabilities on both sides of the heat exchanger, providing greater application flexibility. The single continuous inner tube increases reliability and cleanliness and allows the unit to be completely drainable. FEATURES Fully drainable inner and outer coil Spiral wound for maximum counterflow efficiency Constant fluid velocity No dead spots or crevices Excellent for multi-phase/multicomponent fluids and slurries Highly resistant to thermal and hydraulic shock Materials to meet any application: 300 grade stainless steel, copper, nickel alloys, titanium (inner tube only) or zirconium (inne
