Industrial Evaporator & Coil Tube Bundle for Heat Exchangers
Yuhong Group Co., Ltd. is a leading designer, manufacturer, and international supplier of high-efficiency industrial evaporators, evaporative condensers, and heavy-duty pressure equipment. Serving global process industries through www.tema-heatexchanger.com, we engineer custom evaporation systems and core heat exchange components compliant with ASME Section VIII Div. 1, API 661, and international quality standards.
Whether you require a complete, modular evaporative cooling unit, a custom-fabricated u tube bundle, or replacement elements for an existing shell and tube heat exchanger—such as a precision-machined heat exchanger tubesheet, high-surface finned tube bundle, or stainless steel cooling coils—Yuhong Group provides durable, factory-tested thermal solutions.
Product Types & Design Configurations
Our industrial evaporator and coil solutions are available in multiple structural layouts to suit varied operating temperatures, pressure ranges, and fluid characteristics:
- Falling Film Evaporators: Ideal for heat-sensitive liquids in chemical and pharmaceutical processing, featuring high heat transfer coefficients and low liquid hold-up.
- Forced Circulation Evaporators: Engineered for high-viscosity or fouling fluids, utilizing heavy-duty pumps to maintain high fluid velocity through a vertical or horizontal shell & tube heat exchanger core.
- Serpentine Coil Evaporative Condensers: Features continuous, seam-welded serpentine cooling coils housed in structural steel frames for compact air-and-water combined cooling.
- Thermosiphon & Kettle Reboilers: Specialized flooded evaporator cores designed for oil refining and petrochemical fractional distillation columns.
Material Specifications & Corrosion Resistance
To handle aggressive process media, toxic refrigerants, brackish cooling water, and high-temperature hydrocarbon streams, Yuhong Group supplies evaporators in a comprehensive range of mill-certified materials:
| Component Category | Available Material Specifications | Industry Compliance |
|---|
| Evaporator Tubes & Coils | Carbon Steel (SA179, SA214, Hot-Dip Galvanized), Stainless Steel (304/304L, 316/316L, 321), Duplex (S31803/2205), Titanium Gr.2 | ASME SA179 / SA213 / SA249 |
| Finned Heat Exchanger Tubes | Extruded / Embedded / KL-Type Aluminum Fins on Stainless, Alloy, or Carbon Steel base tubes | ASTM B221 / B209 |
| Tubesheets & Header Pipes | Heavy Forged Carbon Steel (SA105, SA266), Stainless Steel (SA182 F316L), Clad Steel Plates | ASME SA105 / SA182 |
| Enclosure & Casing Frames | Heavy-gauge Stainless Steel (304/316) or Hot-Dip Galvanized Carbon Steel panels | ASTM A123 / ISO 1461 |
Core Replacement Parts & Internal Hardware Supply
In addition to fully integrated skid units, Yuhong Group manufactures standalone internal components for plant retrofits, turnaround maintenance, and capacity expansion:
| Replacement Part | Function in Evaporator / Heat Exchanger System | Engineering Highlight |
|---|
| U Tube Bundle / Serpentine Coil | Primary heat absorption matrix where phase-change evaporation occurs. | Hydrostatically tested up to 35 MPa; stress-relieved bends prevent stress corrosion cracking (SCC). |
| Heat Exchanger Tubesheet | Secures evaporator tubes to the shell or header casing while preventing cross-contamination. | Precision CNC drilled and grooved to ensure leak-free tube expansion and high joint strength. |
| Finned Tube Bundle Assemblies | Enhances air-side thermal dissipation in dry/hybrid evaporative units. | Extruded aluminum fins protect inner tubes from atmospheric corrosion while maximizing heat flux. |
| Mist Eliminators & Drift Eliminators | Traps entrained liquid droplets from vapor streams at the evaporator outlet. | Multi-pass PVC or stainless steel louvers engineered for minimal pressure drop (<50 Pa). |
| Spray Distribution Headers | Distributes cooling water evenly across the tube bundle surface. | Anti-clogging target nozzles provide uniform fluid film coverage across all tube passes. |
Key Advantages & Operational Highlights
- Maximum Thermal Flux & Energy Efficiency: Engineered tube layout geometry optimizes both liquid film distribution and air/water counter-flow, drastically reducing electrical power and water consumption.
- Superior Leak-Tight Integrity: All coil circuits and tube bundle assemblies undergo 100% pneumatic bubble testing, hydrostatic pressure testing, and non-destructive examination (NDT/RT/PT) prior to enclosure.
- Severe Duty Corrosion Protection: Coils and structural frames undergo hot-dip galvanization or acid pickling/passivation to ensure long service life in coastal, sour gas, or high-humidity environments.
- Modular Plug-and-Play Design: Pre-assembled structural modules allow for rapid field rigging and minimal downtime during facility turnarounds.
Technical Knowledge: Critical Considerations for Evaporator & Coil Selection
When sourcing an industrial evaporator or replacing an internal heat exchanger tube bundle, technical buyers and plant engineers should evaluate these crucial parameters:
- Fouling Factor & Fluid Velocity: In forced-circulation and shell-side evaporation, maintaining process fluid velocities above 2.0 m/s inside the shell and tube heat exchanger prevents tube wall scaling and localized hot-spot formation.
- Vapor-Liquid Separation Space: Adequate disengagement height above the u tube bundle is critical to prevent liquid carryover into vapor compressors or vacuum systems.
- Thermal Stress & Expansion Loop Integrity: Serpentine coils and long straight tube runs experience severe thermal cycling during startup and defrosting. Floating headers or slotted support guides must be incorporated to absorb differential expansion ($\Delta T$).
