Plate Heat Exchangers | Industrial processes (food, HVAC, chemical), milk pasteurization | - Material: 316L SS (ASTM A240) ▲ (superior to industry-standard 304 SS) - Max pressure: 20 bar (Base) ▲ 25 bar (Advanced) - Thermal efficiency: 90% (Base) ▲ 92% (Advanced) | - High efficiency (▲ 4% over industry avg 88%) - Compact design (0.5m² footprint, saves 40% space) - Modular scalability (up to 50 plates) | - Higher initial cost (▲ 20% vs shell and tube) - Requires precise fluid compatibility |
Shell and Tube | High-pressure applications (oil refineries, power plants) | - Material: Carbon steel (ASTM A335) - Pressure rating: 1000 psi ▲ (industry standard 800 psi) - Tube passes: 4-8 for high turbulence | - Durable for extreme conditions (▲ over plate exchangers) - Handles high temps/pressures | - Bulky design (▲ 3x larger than plate) - Lower efficiency (60-70%) |
Air-Cooled | Outdoor, water-scarce regions (oil & gas) | - Fins: Aluminum (ASTM B209) - No water requirement: Ideal for arid climates | - Water-free operation (▲ critical in water-scarce areas) - Adaptable to harsh environments | - Lower efficiency (60-70%) ▲ vs plate’s 90% - Large footprint (▲ 10m² for equivalent capacity) |
Spiral Plate | Fouling-prone fluids (wastewater treatment) | - Design: Spiral-wound plates (ISO 15607) - Self-cleaning: Reduces fouling buildup | - Resists fouling (▲ over shell and tube) - Compact for capacity (▲ 20% smaller than spiral tube) | - Difficult maintenance (▲ disassembly required) - Limited scalability (▲ max 10 plates) |
Finned Tube | HVAC, refrigeration (low-pressure systems) | - Construction: Copper-aluminum fins (ASTM B221) - Weight: Lightweight (▲ 30% lighter than steel) | - Cost-effective (▲ 15% cheaper than plate) - Portable for mobile use | - Lower efficiency (▲ 50-60%) - Prone to corrosion (▲ without protective coatings) |
Brazed Plate | Refrigeration, automotive (high efficiency) | - Material: Copper-brazed plates (ISO 14407) - Footprint: 0.2m² ▲ (industry avg 0.5m²) | - Ultra-compact (▲ 60% smaller than plate) - High efficiency (▲ 95% thermal) | - Not suitable for high temps/pressures (▲ max 200°C) - Non-modular (▲ no scalability) |
