Description

Speidel’s FD-DF Red Wine Fermentation Tank integrates Air Pulse technology directly into your fermentation tank without the need for additional equipment.

Increasingly, today’s research is indicating that there are a lot of benefits to controlled oxygen contact during red wine fermentation. Previously considered Public Enemy #1 in the winery, oxygen is now being specifically introduced to the fermenting wine at certain phases.

To make this process easier and more approachable, and to eliminate the need for exterior equipment, Speidel developed their FD-DF tank. The tanks is equipped with a set of 4 programmable air-injection nozzles with inline check valves, for total control on the part of the winemaker. Duration of and interval between air injections can be controlled, as well as the inlet pressure.

The incoming air can be used to break up and flush CO2 from the cap, causing it to fall back into the fermenting juice for better extraction in addition to helping drive tannin complexing reactions and ensuring healthy ferments to reduce instances of slow or sluggish fermentation.

Must Discharge:

Automatic, motorized must-discharge arms with hinged door opening. Must-Discharge motor requires 380V, 3-phase power.

Key Features:

  • Tank ceiling in AISI316 Stainless, tank walls and base in AISI304.
  • Forward set, vertical 40 cm (16”) top hatch with 2” Tri-Clamp ferrule
  • Ladder support bow
  • NW 10 DIN stainless thermowell with thermometer insert
  • NW 20 DIN stainless sample valve
  • Standard 2” Tri-Clamp racking and total drain outlets.
  • Stainless steel electronic control box

System Electrical and Pneumatic Requirements:

  • 220V, 1-phase, 60Hz power for the control system.
  • Speidel recommends an accumulation tank for the compressor that can store 1000L or air compressed to 6 bar (265 gal at 90 psi)
  • Speidel recommends that either the compressor natively outputs a filtered, oil-free air or that the compressed air be conditioned before entering the nozzles and tank/must. As filters, Speidel recommends either the FESTO FRC-1/2-D MIDI-A (Part No. 159591) or the SMC AC40A-F04DE or equivalent.
