THE 40

Summary

Product Identification

• Product Type: Tubular Heat Exchanger
• Series: THE
• Pressure Rating: Medium Pressure - 40 BAR
• Manufacturer: Wila A/S

Description

The THE series Tubular Heat Exchanger is designed for fluid-to-fluid heat transfer, offering both heating and cooling capabilities. It features two pressure chambers within a combined housing: the "Tube side" or "Product side" encompassing the tubes, and the "Shell side" or "Service side" within the outer shell. The heat exchanger is constructed from EN 1.4404 (AISI 316L) stainless steel with a sanitary surface finish.

Operating Limits

• Maximum Product Side Pressure: 40 bar[g]
• Maximum Product Side Temperature: 85°C
• Shell Side Maximum Pressure and Temperature Limits: These vary by heat exchanger size. For steam:
  • 0.5 m² and 1 m²: 10 bar[g] / 185°C
  • 2 m²: 8 bar[g] / 176°C
  • 3 m²: 6 bar[g] / 165°C
  • 4 m² and 6 m²: 3 bar[g] / 144°C
  • 8 m²: 2.3 bar[g] / 136°C

Materials and Surface Finish

• Material: EN 1.4404 (AISI 316L) stainless steel
• Outside Surface Roughness: ≤ 1.6µm
• Internal Tube Side Surface Roughness: ≤ 0.8µm
