BBT Bright beer tanks – tanks for storage and serving beer

Bright beer tanks – the tanks for preparation beer before bottling or serving

Pressure tanks, bottling tanks, serving tanks, bright beer tanks, beer storage tanks – these are the most common terms, including the same class of special pressure vessels designed to preparation bright beer before tapping, bottling into bottles, filling into kegs or other containers. Purified saturated beer is pushed from lager tanks or cylindroconical tanks into bright beer tank under pressure up to 3.0 bar.

The bright beer tank also serves as a target tank when filtering beer or pasteurising beer.

Position of the bright beer tanks as equipment in a brewery

In the case of the production of special beers, carbonation of the beer is carried out in the bright beer tank (if the tank is equipped with a carbonation candle), or a dry hopping equipment is added to the tank and some strongly chilled beers are made, eg IPA type .

Standard Tank Equipment :

  • Basic pressure vessel Bright beer tank schemeThe basic tank equipment is pressure vessel in standard shape – conical shape of jacket with bottom (front) or top (back) bottom. The vessel is designed as pressure vessel since the stage of engeneering design throught the calculation, technology to the final tests and according to required overpressure by customer. Most of the time we produce tank in overpressure 3.0 bar, but we can produce tanks in overpressure up to required overpressure 8.0 bar.
  • Necessary equipment of pressure vessel – A part of the pressure vessel is production card with mandatory data about the tank and about the producers of this tank, registration number of pressure vessel with specification of standard according to which the pressure vessel was certificated (most of the time PED 97/23/EC, optionally GOST, GUM) by the Certification Council, which judges and approves each pressure vessel. The Certification Council for our pressure vessels is most of the time TÜV SÜD Czech. Each produced tank we supply with pressure vessel passport that is a document where all with tank connected events, controls, repairs etc. are filed throughout the tank’s operating life.
  • Safety valve – It is there to protect the tank from the overpressure with higher pressure then for which pressure the tank is produced or certificated. The safety overpressure valve is often in combination with safety underpressure valve which protect the tank from the breaking down because of underpressure in the tank (for example by the drawing down the tank‘s capacity with the pump unit). In bigger tanks there are the safety overpressure valve and safety underpressure valve as an independent armatures.
  • Eliptic Manway – A special lockable door on the side of the tank or on the top bottom which is used for looking over the inside of the tank, for assembling and disassembling of the inner armatures, for adding some ingredients, etc. The door opens inside the tank, after tilting the tank in the horizontal position, it is possible to open the door outsider. A part of the manway is elastic or silicon sealing, closing screws and a special hinge with dumper arm. The producer guarantees a pressure resistance of the manway and the door at least at the same or higher resistance which the beer tank has.
  • CIP Spraying Ball – A ball shower head designed for easy cleaning and sanitation of tank with water and sanitation solutions. The spraying ball usually has effective omnidirectional shower head. The more expensive tanks haveomnidirectional and rotational spraying ball. Throught the spraying ball and its connecting armature (CIP Cleaning Pipe) the pressuring of the tank is executed with help of the external resource of CO2, biogon or nitrogen. The sterile air in combination with a little amount of CO2 is often used for drawing the beverage out of the tank. The CO2 creates insulating layer on the beverage surface.
  • Product outlet/inlet armature – An armature for filling and drawing beer out of the tank.
  • Supporting frame – We supply supporting frames for horizontal beer tanks in different variations. The horizontal beer tanks could be ordered in blocks, for example 2 rows above each other. According to the required set and to disposintional space, the supporting frame is designed individually.
  • Inlet / Outlet with Butterfly Valve – a tube with a shut-off damper at the end that serves to filling or discharge the tank contents. For most tanks is the same valve used also for the filling tank. At customer’s request, we can optionally equip the tank with the inlet with Butterfly Valve – for example, when filtering beer or when the product is circulated via an external pump – most often a beer filter or beer dry hoping equipment.
  • Sample valve – The small cock is used for product sampling during the tasting and laboratory tests. It can be further equipped with a spiral attachment that eliminates the foaming of the beverage and speeds up the sampling process.
  • Temperature sensor in thermowell – A pipe welded to the bottom part of the tank. The temperature sensor of regulation system or some common thermometer for visual measuring of the temperature is inserted into this pipe.
  • Tank Ladder Hooks – According to the requirements of the customer, we install hooks for safe gripping of the ladder on the tanks which are bigger then 2000 mm. A part of the delivery could be a ladder which is compatible with the hooks. Only with the vertical tanks.
  • Transporting Hinges – Hinges for hanging the tank under the elevatory devices (a derrick, a lift truck) are designed for safe transport of the tank. We recommend it as a equipment of tanks from the 500L capacity.
  • Adjustable Feet – Screwing feet on the bottom end of the feet are designed for precise placing of the tank in horizontal or vertical position. Thanks to catchment floor, it is usuall that the tank does not stand on the flat surface.
  • Double jacket – The cooling of the tanks which are cooled with liquid is carried out through heat-carrying liquid (often it is water or glycol) which runs through the double jacket and it is circulating between the double jacket and the cooler. The temperature in the tank is controled with regulation system which measures and compares the temperature in the tank with required temperature based on the program, the regulation system opens and closes valves on access of the double jacket. In the non-insulated tanks which are cooled with the air, the double jacket is not an equipment of the tank.
  • PU Foam Insulation – The tank is usually insulated with polyurethane foam (optionally in other way), which fulfills the space between inner basic tank and outer jacket of the tank. Usually we insulate only the conical part of the tank and according to the customer, we insulate even the bottom or the top bottom or both bottoms of the vessel. In the tank which are cooled with the air the PU insulation is not an equipment of the tank.
  • Temperature Meassure and Control System – In the case that the customer requires it we can supply the tank with the complete system for measuring and regulation of the temperature in the tank, eventually with the water cooler. The whole system is easy to install by the customer and to its installation and for the establishment it is not necessary to have an authorization for work with the electric devices.


Optional Tank Equipment :

  • Fill level indicator  – Product level in the tank is visually indicated by a glass or plastic tube that is connected to the inside of the tank at the bottom and top. An important part of the file level indicator is the connection with the sanitary fittings. The indicators can be supplied without a scale, with a non-calibration scale and with a millimeter scale that is required in some states due to mandatory calibration.
  • Carbonation inlet  – In the production of some short-time brewing beer types, there is insufficient saturation of the beverage with carbon dioxide naturally, with the help of residual yeast activity. This is why the beverage is artificially carbonized using a carbonation candle, which is a special fitting with a stone made of porous material. The candle is mounted inside the tank, small bubbles of CO2 from the cylinder are poured over it for a few hours. For the carbonization of beverages we supply all the necessary fittings and other equipment. The tank has to be fitted with a special connector for the assembly of the candle.
  • Inlet with butterfly valve –  The secondary input valve is used, for example, for filtering beer, or for dry hopping beer, where an external pump is used to circulate the product through a connected external device. Most commonly it is some beer filter or a hop gun.
  • Relief valve (Pressure Adjusting Apparatus) – A special armature for precise adjustment of the required overpressure in the tank is mounted on the tank if the customer wishes to use the tank as a so-called combi tank. The combi tank is equipped both for working with the finished product and for maturing beer (as a lager tank).
  • Racking outlet with Butterfly Valve – Besides the drain fitting at the bottom of the tank, we can equip the tank with another armature, located just above the bottom of the tank, or with a double armature, containing the fittings for discharging the clean product and the entire contents of the tank. It is used to clarify the product (clearing of pure beverage above the sewage sludge level) in case the customer wants to use the overpressure tank also for additional clarification of the product, ie for continuous separation of beer from settled dead yeast.
  • Tank Ladder Hooks – úchyty pro bezpečné zafixování žebříku montujeme na tanky vyšší než 2000 mm na žádost zákazníka. Součástí dodávky může být také žebřík, kompatibilní s háky.
  • Transporting Hinges – Suspension lugs for hanging the tank under the lifting device (crane, forklift) for easy and safe tank transport. We recommend it for tanks that are larger than 500 liters.
  • Tank Stirring Equipment – A device for mixing the contents of the tank with a stirrer – it is placed on the side shell of the tank, exceptionally on the top of the tank. It is mainly used in the production of beers or ciders with flavoring ingredients, which must be thoroughly mixed in the product.
  • Temperature Measure and Control System – If required by the customer, we can supply the tank with a complete system for measuring and controlling the temperature in the tank, or even a water cooler. The entire system is easy to install by the customer, and no electrical work authorization is required for installation and commissioning.

Bright beer tanks, air-cooled, liquid-cooled, insulated, non-insulated

According to customer requirements, we supply pressure bright beer tanks in these variants in terms of cooling and insulation:

1. BBTXN Bright beer tanks cooled by air, non-insulated

These bright beer tanks are in the easiest construction and so it is possible to buy them for the lowest price. These tanks are in mono-jacketed version without any double cooling channels. Tanks have to be placed in insulated chilled room or chilled box, where the space is cooled with cooling unit. Their advanatage is their low purchase cost. And their disadvantage is that the temperature in each tank cannot be regulated regardless of the other tanks and the human operating comfort is lower because opertors work in cold and humid surroundings. The electric consumption is higher when tanks are cooled with air and not with the liquid. But besides that this type of tank is used the most in restaurants because of the investment savings.

2. BBTXI-S Bright beer tanks cooled by liquid, non-insulated

Bright beer tanks non-insulated, cooled with glycolThe most frequently used bright beer tanks are price compromise between tanks cooled with air and insulated tanks cooled with liquid. They are more expensive than tanks cooled with air but cheaper than insulated tanks cooled with liquid. These tanks include double cooling channels and the cooling liquid pours through them – water or glycol, but they do not have any insulation and any outer cover jacket. We recommend to place the tanks in the slightly insulated uncooled room or box, where the redundant heating of tanks is limited. Their advantage is relatively low purchase cost and the disadvantage is higher electric consumption when the tanks are cooled and also the need of more powerful liquid cooler then it is needed with insulated tanks.

3. BBTXI Bright beer tanks cooled by liquid, insulated

Insulated bright beer tanks cooled with liquid is professional solution for all restaurants keepers for whom the savings of operating costs are at the very first place. Tanks include double cooling channels and the cooling liquid pours throug them – water or glycol, and what’s more the tanks have a cylindrical part (for some extra pay both bottoms could be insulated) insulated with PU foam. The outer jacket is covered with insulation and it creates a clean design of stainless steel tank. It is possible to place the tanks in a non-insulated room because insulation provides the protection against unwanted escape of cold nearby the tanks. Their advantage is all above their low electric consumption when the tanks are cooled, the need of the less powerful liquid cooler and better comfort for operators who cannot work in cold room.

We produce pressure bright beer tanks with variable dimensions and orientations

We can customize the dimensions and spatial orientation of the overpressure bright beer tanks according to customer requirements. We produce vertical and horizontal bright beer tanks, with the side-to-tank ratio being selected from several variants.

1. BBTVX Vertical bright beer tanks

The vertical orientation of bright beer tanks has a many practical advantages:

Effective sanitation of the whole tank with only 1 spraying ball (cost savings).

Manually easy cleaning of the inner and outer area of the tank – usually it is possible to stand in the inside of the tank and it is possible to walk around the tank.

Small space of floor area, effective usage of vertical room space.

Easy manipulation and access to all armatures and functional parts of the tank.

Precise tracking of product quantity in a tank using a gauge.

2. BBTHX Horizontal bright beer tanks

The horizontal orientation of the tanks is practical in breweries with insufficient height for the location of vertical bright beer tanks.

Horizontal bright beer tanks can be composed of several layers (batteries) to maximize the available room height. The main disadvantage of horizontally oriented tanks is, in particular, poor access to hidden parts of the tank, where is accumulated dirt, which is the source of unwanted infections of yeast and beer. We recommend it only for microbreweries with a really low ceiling height in the beer cellar.
