Versatility
The bar world has undergone profound changes, from bars essentially serving coffees and drinks today they have become multi-purpose meeting places, where depending on the time of day they serve a wide variety of food and drinks, from coffee and cakes in the morning to complete meals with quality wines and sophisticated cocktails in the evening. Glass washers must be able to match this continuous evolution step by step, without however increasing in size, as space is certainly the scarcest and most precious resource inside the bar.
The new generation of Colged glass washers offers an effective solution to this problem: despite the compact external dimensions which can be adapted to any bar counter compartment, the door opening height means that glasses and plates measuring up to 30 cm can be stacked and washed. As there are many different types of commercial business, the Colged range is structured into different families of machines of increasing capacity and different mixes of rack size and door opening height, intended for different uses: from the small cup/glass washer with 35 rack to versatile machines with 40 cm racks up to larger machines with 45 or 50 cm racks, which can also be used as cutlery washers.
The table demonstrates all this variety at a glance, and can help you to select the most suitable type of product for your needs.
Special bar - double rack
Breakfast at the bar, with coffee or cappuccino, is a ritual that few people are willing to miss out on. This means that early in the morning there is a lot of work, creating authentic mountains of cups, saucers and spoons piled up in the rack; this frequently leads to breakages, and often washes that are not 100% perfect.
Washing lots of items in a short time is not the right answer. Colged proposes a rational way of washing large quantities in a short time: the removable double rack. With its extra-large door opening height 32 cm, all glass washers with 40 x 40 cm rack can be equipped with an optional support for washing two racks at the same time. The lower rack is used to wash cups with max. height 12,5 cm, and the upper rack saucers with a diameter up to 15,5 cm and spoons. This means that productivity remains hight, but the items are stacked tidily to avoid overlapping and unwanted contact. Once the breakfast rush-hour is over, the double rack device can be removed in just a few seconds, without taking up any additional space, and the glass washer is instantly ready for washing cocktail glasses and plates with up to 30 cm diameter, for the aperitif hour or lunchtime.
Operational flexibility
Space is a valuable resource in any bar and this is why Colged has created truly multifunctional dishwashers that are able to fulfi l a variety of very different functions as the need arises. All our glasswashers machines have three standard programmes for glasses, up to three programmes for self-cleaning and tank water changing and up to four specialised programmes.
Standard programmes Differ not only for their contact time (cycle duration), but also for their wash and rinse temperatures and water consumption. Each programme is designed for a specific purpose: ProSpeed: for fresh, light soiling; ProFessional: for general use; ProTemp: with high temperature water rinse.
Specialised programmes Transform the glasswasher into a real dishwasher, into a cutlery washer and into a machine suitable for osmosis device system. ProCold: with two rinses, the first with hot water and the second with cold water; ProPlates: for plates; ProWater: specially for osmosis water; ProSteel: for steel cutlery.
Easy cleaning
Colged dishwashers are constructed in accordance with the TotalClean design philosophy to make end-of-shift cleaning operations as quick and easy as possible. This entails a number of important design features:
Construction No pipes inside the wash chambers, deep-drawn rack guides with no blind spots where dirt can accumulate, unblockable integral surface strainers, with 2.5 mm diameter mesh and dished to trap dirt during emptying.
Functionality Progressive triple-stage fi ltration of the tank water with elimination of particles down to a diameter of 0.8 mm; programme for self-cleaning of the wash chamber; wash arms with the EasyHandling system, which means they can be removed simply by pressing a button and then clicked back into place.
Self-clean programmes These programmes simplify and speed-up end-of-shift operations and allow rapid changeover of all the water contained in the wash tank. Depending on the model and the version, the machine may offer up to three programmes of this type. ProSelf: self-clean cycle for machines with gravity draining; ProNew: total water change; ProClean: self-clean cycle with high-pressure jets for machines with EvoLution draining; ProDrain: automatic tank draining.
Water distribution system
The main component is the HiTech arm made from a composite material called ProComposit (30% fibreglass, 30% talcum microparticles, 40% organic resin). During rinsing, patented UltraRinse3 geometry ensures that the water is used more effectively and effi ciently, thereby helping to minimise consumption.
The washing nozzles are on the same level as the rinse nozzles; this means that the spray is not obstructed, as is the case with the normal arrangement of separate wash and rinse arms. The arm rotates on 3 graphite bearings which reduce friction to virtually zero; this means the full force of the water from the pump is applied to wash the dishes rather than to rotate the arm via the reaction holes.
The HiTech arm features a snap-fi t attachment system, which makes it easy to install and remove for cleaning, even with just one hand. Its mechanical strength, elasticity, resistance to chemical attack and simplicity of cleaning make this component particularly effective.
Washing system
The heart of the system is the powerful pump with patented DuoFlo technology. Thanks to the pump’s two outlets, with one outlet connected directly to the upper arm and the other to the lower arm, this system eliminates the loss of pressure caused by dividing the fl ow; in this way all the energy absorbed is transferred to the water, thereby achieving an effect equivalent to an enhanced conventional pump. This means the same performance is achieved as competitors’ products but with an energy saving of 25%.
A shorter wash cycle, with lower water and detergent consumption, is possible only with a higher wash temperature. Unfortunately, the majority of products on the market have tank and boiler heating elements that function alternately, with priority given to the boiler for reasons of hygiene. This means that, with repeated cycles, the tank is not heated suffi ciently and its temperature falls rapidly, thereby compromising washing results. On the new Colged dishwashers, the HotWash system instead shares the electrical power between two independent heating elements so as to allow numerous repeated wash cycles and constant heating of the tank. The result, compared with a machine with interlocked heating elements, is that the temperature is around 10 degrees higher during repeated wash cycles: this allows a shorter wash time and a shorter drying time as the plates get hotter, lower detergent consumption and consequently lower costs.
With the ProDose, system, detergent products are dosed by an electronically-controlled peristaltic pump, which can be easily adjusted from the control panel, and which ensures constant, precise dosing of detergent and rinse aid without any wastage. On request, the machine may be equipped special level sensors that signal via a message on the display when the detergent tanks need to be changed, thereby avoiding the risk of the dosing units being damaged by running empty.
Rinsing systems
Colged dishwashers employ a number of different rinsing systems, with different levels of complexity and performance, each of which however is capable of ensuring that certain parameters remain constant: Timed rinse: uses ThermoStop to ensure a constant temperature at the start of the rinse cycle; the duration of the cycle is fi xed, while the water consumption level depends greatly on the pressure of the mains water supply. It is used on the models 00 - 10 - 20.
The minimum water consumption is 1,5 litres/cycle. Volumetric rinse: uses ThermoStop to ensure a constant temperature at the start of the rinse cycle; the duration of the cycle is variable and depends greatly on the pressure of the mains water supply; the average water consumption is constant and independent of the supply pressure. It is used on the models 01 - 11 - 21.
The minimum water consumption is 1,5 litres/cycle. ProRinse: ensures that the initial and average rinse temperatures, the flow rate, the pressure and the duration all remain constant. All the physical parameters that determine optimal rinsing are controlled and managed, and this why it is possible to get consumption down as low as 1.5 litres/cycle and achieve constant results, regardless of the characteristics of the water supply. The water is supplied via a beak tank, which conforms to WRAS anti-pollution standards, a non-pressurized boiler and a rinse water suction pump. It is used on the models 12 - 13 - 22 - 23.
Filtration systems
Colged dishwashers are equipped with two systems for fi ltration and drainage of the wash waster with different degrees of complexity: ArchiMedes - A patented system that exploits the principle of communicating vessels to ensure that the dirtiest water at the bottom of the tank is the first to be drained under the pressure of the cleaner water above. This simple but effective device raises the effi ciency of the water changeover from the 66% generally obtained with a conventional overflow drain, to 83%; the result is cleaner water in the tank, with the possibility to reduce the amount of water used in the rinse cycle and the concentration of detergent used. It is used on the models 00 -10 -20 -22.
EvoLution3 - A complete and effective system which uses 3-stage water filtration with progressively decreasing mesh size down to 0.8 mm. The water is drained from the bottom of the tank by a specifi c pump and drainage takes place after washing and before the start of the rinse cycle. This makes for a 100% efficient water changeover and maximum cleanliness of the water in the tank. It is used on the models 01 -11 -13 -20 -23.
In both systems surface filters are used (either in steel or composite material depending on the model) that extend the full width of the tank and are therefore virtually unblockable. We can therefore do without the filter presence sensors or clogging sensors used on many of our competitors’ models as they serve no purpose.
Water treatment systems
Depending on the model, the dishwashers may be equipped with a conventional built-in water softener or with the CareFree continuous water softener. With the former type, the user has to stop work and manually start resin regeneration after certain number of wash cycles, which depends on the characteristic of the water supply. The continuous water softener instead automatically performs regeneration during every wash cycle; the only action required of the operator is to top up the salt when requested by a message displayed on the screen of the user interface.
In addition to built-in systems, Colged also offers large-capacity external water softeners, in both manual and automatic versions, decarbonation systems and reverse osmosis filtration system to obtain water that is perfectly purified; osmosis water is especially recommended for washing crystal glasses and cutlery, but has no advantages for washing dishes.
