| Category | Parameter | Specification Range | Remarks |
|---|---|---|---|
| Design | Flow Configuration | Counter-current, Cross-flow | Counter-current maximizes ΔT efficiency (>85% recovery possible). |
| Spiral Layers | Dual-channel (standard), Multi-channel (custom) | Channels isolated for cross-contamination prevention. | |
| Core Components | Plate Material | Stainless Steel (304/316L), Titanium, Hastelloy C-276, SMO 254 | Exotic alloys for HCl/HSO services; SS316L standard for most apps. |
| Plate Thickness | 4-12 mm | Thicker plates for abrasive slurries/high pressure. | |
| Channel Spacing | 5-30 mm | Wide gaps (20-30mm) for viscous/slurry fluids; narrow for gases. | |
| Spiral Diameter (OD) | 300-2000 mm | Larger diameters for higher capacity. | |
| Performance | Heat Transfer Area | 5-500 m² | Compact: 2-3× higher U-value vs shell-and-tube. |
| Max Pressure | 25 bar (standard), 40 bar (heavy-duty) | Limited by spiral sealing mechanism. | |
| Temp Range | -50°C to +400°C | Gasket-free designs for extreme temps. | |
| Approach Temp | As low as 3°C | Ideal for low-grade heat recovery. | |
| Fouling Control | Self-Cleaning | High turbulence (Re > 2000), no stagnant zones | Handles sewage, sludge, pulp, crystallizing fluids. |
| Access | Removable end caps, full-channel access | Mechanical cleaning without disassembly. | |
| Construction | Frame Material | Carbon Steel (painted), SS304/316, FRP | FRP for coastal/chemical exposure. |
| Sealing | Gasket-free (welded), Gasketed (NBR/EPDM/Viton) | Welded for corrosive fluids; gasketed for maintenance flexibility. | |
| Connections | Nozzle Sizes | DN50-DN500 | Flanged (ANSI/DIN/JIS), threaded, or butt-weld. |
| Nozzle Location | Axial, Tangential, Radial | Tangential entry reduces erosion in slurry flows. | |
| Standards | Compliance | ASME Sec. VIII Div. 1, PED 2014/68/EU, AD2000-Merkblatt | Third-party inspection (TÜV, Lloyds) optional. |
| Testing | Hydrotest (1.5× DP), Dye Penetrant (welds), Helium Leak Test | PMI (Positive Material ID) for alloys. | |
| Applications | Typical Services | Wastewater Sludge, Caustic Soda, TiO Slurries, Geothermal Brine, Sugar Crystallizers | Excels in fouling/particulate-laden fluids. |
| Customization | Options | Pass Partition Plates, Dual Media Channels, Insulation Jacket, CIP Ports | Partition plates for multi-pass configurations. |
| Special Designs | Vapor Condenser, Vertical Orientation (floor space saving) | Vertical units for limited footprint areas. |
