2.0 DESCRIPTION
OF THE M20 SYSTEM
2.1 GENERAL OVERVIEW
Draught Master (DM) Modular 20 (M20) is a draught equipment system using PET (polyethylene terepht-
halate) kegs used in Europe since 2011. The kegs are available in a 20L. size and suitable for recycling. The
assembly includes a Modular 20 unit (keg module), which is a pressurized plastic vessel (air working pressure
2.8 – 3.0 bar) supported by an external frame/structure that is designed to facilitates the beer keg.
The system employs a combination of equipment such as cleaning equipment and pressure source that provide
the necessary cleaning and pressure possibility to pressurize the keg module in GF PP Polymer, where the
20L keg container containing carbonized liquids, such as beer is inserted. Here the beer it driven through in-
sulated polymer pythons parsing a beer cooler and forward to tap or taps in a serving area for serving customers.
The steel kegs and couplers are replaced by keg modules and the CO2 equipment (cylinder + regulators) by
a compressor. The compressor is allocated in a semiautomatic cleaning module which allows the bar sta to
clean himself.
2.2 THE SYSTEM
The advantages of the system are:
• Better quality of beer for Consumer.
• No CO2 bottles.
• Light one-way kegs.
• Less waste of beer.
• Long shelf life (6 months before opening, 31 days once
opened).
• Lower environmental impact. This is coupled to the
Draught Master system either in the cellar or in under
bar outlets.
The system uses a bespoke compressed air system that is also an integrated cleaning system. The pressure
driven cleaning system uses advanced technology tracking the line cleaning activity in the outlet and when
the maximum length of time between cleans elapses then the system will stop dispensing and the screen on
the cleaning unit will flash to indicate this. Only after the lines have been cleaned will it then allow product
to be dispensed. The system does have a postpone button which can be used once only each time; this is
for when the total time elapsed and it can be extended by 1 day. The cleaning unit will require a permanent
water supply. A drain tube is fitted to the cleaning unit, so this will need to be either routed to a drain or
a suitable container such as a 5 lt. container. The cleaning unit can be located away from the keg modules
(up to 4 m away through the extension pipe connection). If the cleaning module is located next to the keg
module then place it on the left side as the water/compressed air outlet is situated on the right side of the
cleaning unit.
3.0 INSTALLATION
AND TAKEN INTO USE
3.1 INSTALLATION
DM Modular 20 is installed by a professional Technician appointed by Carlsberg Breweries A/S before handed
over and taken into use by the customer. The installation can contain of an Cleaning equipment, min. one Keg
Module, Pythons, beer cooler, foam stop and beer boost pump. The installation is mounted on a rack or base
pallet with or without wheels. Depending on installation the modules can also be stacked in layers.
Before start up and during handover the customer should be handed out the troubleshooting card and be part
of a step-by-step instructions according to troubleshooting. The technician should give examples and physically
show customer how to clean, how to change a keg, and check beer is running correctly through taps.
The Technician will go true the following points together with the customer:
• How to change the keg incl. the handling of the kegs from cardboard opening to keg loading into the keg
modules including the keg storage.
• How to remove the keg from the keg module, stressing the importance of waiting for the decompression
of the chamber before removing the lid.
• How to preform a cleaning process where applicable.
• Safety instructions..
• What are the error messages of cleaning modules.
• The countdown (number of days till the next cleaning process).
• How to react to basic messages from the system to avoid – troubleshooting before calling for service.
• Check ice bank in cooler.
• Avoid leaving the detergent in the pipes throughout the night because it aects their functionality.
• How to use the equipment, including the periodical gasket cleaning, pressure chamber
cleaning, and hints to ease the lid opening/closing.
• Check power supply for cleaning module.
• Check cleaning detergent is connected to cleaning module before opening.
• Check the water valve is connected and open.
• How to read trouble shooting instructions.
The Technician have gone true the following points before handover:
• Go through entire installation for any leaks:
• Connections at the beer cooler.
• Connections at the keg modules.
• Connections at the cleaning modules
• Check connections at beer tower for any leaks.
• Check light in product branding.
