Dual Tube Coil (DTC-4)

Product catalog summary
Overview: The Sentry® DTC-4 tube-in-tube heat exchangers are designed for applications requiring cooling or heating of high temperature and/or high pressure fluids at low flow rates. These exchangers are spirally wound and operate on a full counter flow principle.
Models: The document lists several models including DTC-CUA/CUA-4-1-1, DTC-SSA/CUA-4-1-1, DTC-IN1/CUA-4-1-1, DTC-SSA/SSB-4-1-1, and DTC-IN1/SSB-4-1-1.
Benefits: The tube-within-a-tube design offers high pressure and temperature capabilities, flexibility in application, and ease of connection to various interfaces. The design ensures reliability, cleanliness, and complete drainability.
Features: Key features include fully drainable coils, spiral winding for efficiency, constant fluid velocity, absence of dead spots, and resistance to thermal and hydraulic shock. Materials used can include stainless steel, copper, nickel alloys, titanium, or zirconium.
Specifications: Each model has specific pressure and temperature ratings, with inner and outer tube materials varying from copper to stainless steel and Inconel. The heat transfer area is consistent across models at 1.26 ft² (0.12 m²), and the weight is 12 lb (5.5 kg).
Performance Data: The performance data includes approach temperature and pressure drop information for various flow rates, with cooling water at 95°F (35°C) and a pressure drop of less than 18 psi (1.2 bar).
Applications: These heat exchangers are suitable for conditioning gases, liquids, slurries, solids, powders, steam, and water.

Dual Tube Coil (DTC-4)-1

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
