Evaporators For Static Tunnels

Evaporators For Static Tunnels

SBF evaporators are intended for installation in small/medium size static tunnels, especially in tunnels for quick freezing of bread by trolleys or similar applications.

Manufactured with stainless steel tube and aluminium fin (StSt/Al). Compatible with all refrigerants (NH₃, CO₂, glycol, HFC, etc.). Modular design from 2 to 8 axial fans (Ø630). Fins pitch: 7-9-10-11-12 mm.


  • Tube geometry. Tube 5/8″ 50×50 in line
  • Tube material. Stainless steel AISI 304 (or AISI 316 on request)
  • Corrugated aluminium fins (0.25 mm thick), in order to turbulence the air passing through the coil and increase heat transfer
  • Stainless steel screws
  • White thermo-lacquered aluminium casing
  • Removable side covers. Easy access to coolant connections
  • Tray insulated with polyurethane as standard to avoid condensation. Tray made entirely of GRP (fiberglass reinforced polyester), a light and resistant material, rigid, resistant to corrosion and a good thermal, acoustic and electrical insulator
