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.

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.

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:

In addition to fully integrated skid units, Yuhong Group manufactures standalone internal components for plant retrofits, turnaround maintenance, and capacity expansion:

1. 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.
2. 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.
3. 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.
4. Modular Plug-and-Play Design: Pre-assembled structural modules allow for rapid field rigging and minimal downtime during facility turnarounds.

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 ($\Delta T$).
