The FO2 tank from Speidel is one step up from their BO style tank and is a great option for home winemakers and wineries with small lots of wine to store. Speidel's unique pocketed tank bases are molded into shape so there are no welds on the bottom surface of the tank, and offer complete drainage. All FO2 tanks are equipped with 1.5" TC racking and drain ports. Key Features Available in four sizes: 300L, 530L, 675L and 910L 300L tank has a 17mm wide top flange, all other tanks have a 42mm wide flange Tanks from 530L up have a reinforcing plate at the racking valve to prevent tank wall flex and to support a tank mixer Liter scale on exterior of tank On three legs Click Here for more information on the key features of all Speidel Tanks.

Speidel's FD-MKEH Tanks represent the ultimate level of premium wine fermentation: a world-leading stainless steel tank with the organoleptic and stabilizing benefits of oak tank walls. These tanks use premium quality german oak to produce a tank which provides micro-ox during fermentation, distributes heat effectively across staves, and is less susceptible to fluctuations in ambient temperature. And best of all, this stainless/oak hybrid tank combines all of the benefits of a 100% oak container with easier cleaning and the ability to easily replace staves individually or on the whole as necessary at significantly lower cost than replacing a 100% oak vessel. The FD-MKEH tank is equally at home being used as a fermenter or a storage tank and can be used with either red or white wines. The oversized top hatch allows for traditional manual pumpovers and punch downs, giving you the ultimate control over fruit handling. FD-MKEH: The Best of Both Worlds Key Features: Tank ceiling in AISI316 stainless steel, tank floor and frame in AISI304 55mm thick oak staves with innovative Spediel goove-joint between the wood and the stainless frame. Centered, vertical 80 cm (32”) top hatch with 2” Tri-Clamp ferrule Ladder support bow 53x40 cm (21x16 in) forward sloped Fermentation Manway Integrated port and mounting points for optional sight guage (port comes capped) NW 10 DIN stainless sample valve port. Sample valve not included. 2” Tri-Clamp drain and racking outlets.

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 gate-style opening allows for fine netering of how fast you allow must to flow out of the tank. Especially useful with thin musts. 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.
