About the cylindrical storage tanks cooled by air

… in comparation with the beer maturation tanks cooled by water or glycol

These beer maturation tanks – lager tanks have an easiest construction and so it is possible to buy them for the lowest price. These tanks are in single-jacketed version without any cooling channels. Tanks have to be placed in insulated chilled room or chilled box, where the space is cooled by air 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. However, this type of the beverage-production tank is used the most in restaurants because of the investment savings.

The vertical orientation of cylindrical tanks has a many practical advantages:

• Effective sanitation of whole tank using only one ball-washer (cost savings).
• Very easy manual cleaning of the inner and outer side of the tank – usually it is possible to stand in the inside of the tank and it is possible to walk around the tank.
• Smaller floor-space requirements, 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 filling level indicator.

I. Dimensional variability of the maturation tank MBTVN-7000 liters :

We produce the beer maturation tanks and the tanks for storage pure beer with volume 7000 liters in five production lines according to the ratio of the height and diameter of the container. It is advantage for customers, because variable dimensions of tanks is often necessary to adapt for limited space dispositions. Possible dimensions variants :

In this eshop we describe only a standard variant of the tank for storage pure beer with useful volume 7000 liters. If you want another variant, send us your request and we will send you an individual quote for the tank.

Variations of the maturation tank MBTVN-7000 liters according to its overpressure limit :

• Medium-pressure cylindrical vessel 7000 liters – The maximum available overpressure is 3.0 bar, includes PED certificate for pressure vessels – the container can be used as pressure bright beer tank for tapping of beverages into kegs or bottles, filtration and drafting of beer or cider with manual or automatic fillers.
• High-pressure cylindrical vessel 7000 liters – We can produce also the tank equipped with valves for higher overpressure than 3.0 bar – we will prepare an individual offer for the special variants of tank.

Variations of the maturation tank MBTVN-7000 liters according to its quality and equipment :

According to quality requirements and financial possibilities of customers we recognize the cylindrical pressure tanks and bright beer tanks with three classes of quality and equipment:

• HQ – High quality – High quality workmanship of all parts, welded joints and surfaces. The inner surface has a guaranteed roughness Ra<0.5 μm – glossy design. The outer surface is unified. All functional armatures and fittings that have an impact on the reliability and safety of the products are made in Europe or in the USA. Luxury equipment of the tanks. The main advantages are the savings of sanitizing solutions, water and energy, minimized losses of beverages, shorter work time, reduction of production costs. Three years warranty for stainless steel main parts and also for the fittings. The quality class for the most demanding customers.
• SQ – Standard quality – Standard quality workmanship of all parts, welded joints and surfaces. All functional armatures and fittings that have an impact on the reliability and safety of the products are purchased from approved suppliers from Europe or USA. Inspection of all critical welds and joints. The inner surface has a guaranteed roughness Ra<0.8μm – grinded design. Usual equipment af the vessels, usual set of fittings. Tanks in this quality class comply with all European regulations for pressure vessels and food processing plants. Two years warranty for stainless steel main parts, two year for the fittings. It is the most often ordered quality variation of tanks for our customers.
• LQ – Lower quality – Lower quality workmanship of all parts, welded joints and surfaces. The most of functional armatures and fittings are purchased from approved suppliers from Asia. The inner and outer surface are not unified. Not guaranteed surface roughness on the inside of the containers. This solution is interesting only for starting small breweries because it saves an investition costs. Unfortunatelly, this brings higher beverage production costs. Longer period of sanitation, greater consumption of the sanitizing solution, energy, labor and hot water. High losses of produced beverages. We don´t offer this quality class for our products, because the equipment with the LQ quality class does not comply with the European regulations for pressure vessels and food processing plants. It is the quality of tanks of very cheap world producers of the tanks.

Our quality declaration: Why should you buy this type of the tank just from us?

1. We design, manufacture, weld, mount and test of all vessels (excluding non-pressure vessels) in accordance with the strict European standards and guidelines for pressure vessels (EU Directive PED 2014/68/EU Pressure Equipment). I.e :
   • Each pressure vessel contains a double-acting air vent valve (prevents against an over pressurization or implosion of the tank during its charging / discharging)
   • Each pressure vessel also contains an independent overpressure safety valve (prevents against a very dangerous overpressurization of the vessel and the subsequent explosion during a malfunction or insufficient capacity of the double acting air vent valve)
   • Each pressure vessel is designed by certified designer who is qualified for the designing and calculation of pressure vessels.
   • Production documentation for each pressure vessel containing static strength calculation, the exact description of a right manufacturing process, including the required types of welds, thickness of material, critical points solutions.
   • All the manufactured pressure vessels are subjected to rigorous testing of tightness and porosity of welds, using a special liquid that detects even the slightest unwanted leaks, pores or micro-cracks = The Penetration Test
   • Pressure vessels are tested at overpressure which is at least 1 bar higher than the overpressure, for which containers are certified.
   • The Protocol on the tightness and pressure tests and the EU declaration of conformity are issued to all pressure vessels. We also attach the Document of pressure tank history., at the request of the customer.
   • Manufacturing processes, design drawings, manufacturing, tightness and pressure tests are supervised by an inspector of TÜV SÜD Czech or another certified company, supplying quality control and compliance with European standards.
   • Each pressure vessel contains an indelible nameplate with the obligatory name of the manufacturer, the ultimate pressure or other data that uniquely identifies the concrete pressure vessel in accordance with EU PED 2014/68/EU
2. We produce food containers fundamentally from food-friendly stainless steel that fully comply with the Regulation of the European Parliament and Council Regulation EC no. 1935/2004. These materials do not release their constituents to food in quantities which could endanger human health or bring about an unacceptable changes in the composition of food or a deterioration in their organoleptic and sensory characteristics in contact with food under normal or foreseeable conditions. We do not use cheap stainless steel with lower quality, which will soon lose their corrosion resistance and inactivity to food, especially after repeated contact with aggresive solutions during the cleaning and sanitizing process.
3. We are looking into suppliers of construction and installation materials and components from which we produce equipment for food production and handling. We do not buy any material from importers who are unable to prove its European origins and characteristics.
4. All the tanks, which we design for maturation, maturation and storage of beverages, have optimized dimensions for the maturation processes, maturation process, carbonation, carried out in accordance with technological standards for beverages production. We never determine the dimensions of the tanks only by estimate .
5. All tanks that are made in SQ/HQ quality class, are produced with the guaranteed inner surface roughness of Ra < 0.8 microns or less , which is the European standard prescribed roughness of the inner surfaces of the tanks that come into contact with food and sanitation alkalic and acid solutions. Guaranteed roughness of the inner surface of the vessel is extremely important to ensure thorough cleaning and sanitation tanks. This is an essential prerequisite for achieving purity and sterility of food production equipment. We repeatedly do measurements of all internal surfaces of tanks with the special roughness-meter TR-130 during all their manufacturing process. We polish the inner surface of the tank until the desired roughness is reached.
6. Each container is designed and manufactured in such a way as to ensure easy cleaning and sanitizing of all surfaces that come into contact with food. Therefore, the vessels are equipped with at least one sanitation shower, removable and sanitizable fill level-indicators and sampling cocks. We do not use any cheap armatures, for which the manufacturer has failed to sanitary design and cleanability.
7. Tanks have an united outer surface. All joints of the outer sheets (thickness at least 2 mm) are either welded or completely sealed. This is important to prevent ingress of moisture into the double casing, moistening the insulating material and the loss of insulating ability. This ensures a consistent quality and insulating capacity of the tanks. For containers in SQ quality the external sheets are usually riveted and they have a thickness of at least 1 mm.
8. We isolate all the pressure vessels by quality PUR foam. The insulating polyuretan foam is professionally applied to the insulating space of the tanks so as to avoid formation of thermal bridges, unisolated empty space or deformation of tanks. We do not use cheap little functional replacements for the isolation of the tanks such as insulating wool, polystyrene beads, inexpertly applied foam.
9. Diameters of nozzles, valves and piping are sized correctly according to the volume and vessel function – we do not mount underpowered functional elements on the tanks.
10. The warranty for the tanks produced in HQ is 36 months. The warranty on tank in SQ quality is 24 months. The practical life of the tanks is usually several decades, while elements with lower lifetime (valves, seals, etc.) can usually to be easily replaced with a new standardized elements of the same or another manufacturer.
