NAME:G Series High-Efficiency Evaporator Air Cooler | New Energy-Saving Design for Cold Room & Commercial Refrigeration Systems
1. Structural Design
▸ Corrosion-Resistant Casing
Base model: 1.2mm SGCC steel with cryogenic powder coating (-40℃~120℃ operational)
Upgrade options: 5052-H32 aluminum alloy / 304 stainless steel (IP65 certification available)
2.0mm aluminum alloy tube sheets prevent thermal expansion leakage (ΔL/L₀ ≤0.12%)
2. Dual-Layer Condensate Management
✓ Outer Pan: Hinged access panel with 15° ribbed drainage slope (EN
16713 compliant)
✓ Inner Pan: Seamless aluminum construction reduces air bypass
(<3%)
✓ Ice Prevention: Integrated heating cables (3.5W/cm²) with PT1000
thermal sensors
3. Enhanced Thermal Exchange System
• Coil Design: Φ9.52mm micro-grooved copper tubes (HCFC-free
compatible)
• Fin Configuration: Sinusoidal aluminum fins (FPI=16) with
hydrophilic coating
• Airflow Pattern: Δ-arranged tube matrix enhances NTU by 22% vs
conventional designs
4. Performance-Oriented Components
EC Motor Fans: IP55-rated, Class F insulation (25,000h MTBF)
▶ Speed range: 800-1800 RPM (PWM controlled)
▶ Operating envelope: -40℃~60℃ ambient temperature
Defrost System: 316L stainless heating elements with PID control
▶ Surface load: ≤1.8W/cm² (UL 1995 compliant)
▶ 4-zone thermal distribution (σ≤0.85)
5. Engineering Certifications
✓ Pressure tested at 25bar (362.5psi) per ASME BPVC Section VIII
✓ Refrigerant compatibility: R404A/R507A/R134a/R22 (ASHRAE 34
compliant)
✓ Fin spacing options: 4.5/6.0/9.0mm (EN 327/328 certified)
6. Customization & Quality Control
◈ Electrical housing: NEMA 4X junction box with Phoenix terminals
◈ Production validation: 100% helium leak test + 24hr load
simulation
◈ OEM services: CFD-optimized airflow designs available
Technical Advantages Highlight
① 35% Energy Saving - Optimized airside ΔT through enhanced turbulence
② Zero Ice Accumulation - Smart defrost cycle (Patent pending: CN202310XXXXXX)
③ 20-Year Service Life - Salt spray test >1000hrs (ISO 9227 NSS standard)
