Rack conveyor dishwashers Technology and Harmony

Colged rack conveyor dishwashers Efficiency and Rapidity Colged presents a complete range of rack conveyor dishwashers offering a choice of different throughputs, dimensions and configurations, to provide the optimal dishwashing solution for users of all types, ranging from a large company canteen to a small health facility. The IsyTech range offers single-rinse dishwashers with one or two wash tanks and throughputs of up to 270 racks/hour; the ProTech range is comprised of machines with double or triple rinse cycles, with recirculation and throughputs of up to 320 racks/hour; the dishwashers of...

High production This tried and tested technology is exclusive to Colged and guarantees that the electrical power supplied to the pump is converted into mechanical washing action in the most efficient way possible. Conventional pumps have one inlet and one outlet, the pressurised output flow is distributed to supply the upper and lower spray arms through a Tee joint; DuoFlow has instead one inlet and two tangential outlets, each of which is connected directly to the spray arms. By removing the Tee joint from the circuit, we have eliminated the main source of pressure loss, thereby ensuring better...

High production It is a heavy module with length of 820 mm, with a complete IdroWash system with 3 arms. Most of the dirt is removed here and the most consistent fraction is collected by a drawer filter, which can then be emptied in just a few seconds without opening the door. A second separation takes place in the ProStrainer surface filter, which is shaped in a way to convey the dirt into a removable basket. A third filter is found on pump suction. It is a very heavy module with length of 1.150 mm, with a complete IdroWash system with 5 arms. Most of the dirt is removed here and the most consistent...

ProWind Drying DuoWind heavy-duty drying module It uses air at 70 °C, withdrawn from the outside and heated by a 6 or 9 kW heat exchanger. A 550 W radial turbo fan sends a flow of 1.400 m3/hour to two upper outlets; a shaped conveyor sends the air upwards again. Drying is optimised for plates but also for the glasses and concave objects that must receive air from below. The air blades also have the effect of maintaining the steam inside; there is a dripping area between rinsing and drying. The use of dry air at a relatively low temperature allows to treat even the most delicate glasses or plastic...

Lower operating cost ProPortional Flow Change Device ProPortional Flow Change Device It re-uses the final rinse water several times to carry out an intermediate double rinse and preliminary rinse at the end of the wash area. The preliminary rinse removes most of the detergent present on the tableware, keeping it in the wash tank. The double intermediate rinse completes removal and the final rinse distributes rinse aid onto the thoroughly clean tableware and promotes drying. This multiple and differentiated use reduces specific water consumption to very low values, with a saving of 36% with respect...

ProChem Detergent Management HiTech Rinse Arms A sequential dual rinse system designed to offer maximum performance in heavy-duty applications and with infrequent changes of the water in the wash tanks. The system is comprised of two separate boilers, each of which feeds a pair of rinse arms, with the water flow pressurised by a dedicated rinse pump. This ensures excellent results independently of the water supply pressure, and the wash tanks receive sufficient water to ensure that dirt is adequately diluted. It reduces the consumption of detergent from 20 to 60% depending on the program used....

Lower operating cost ProHeat heat recovery system ProHeat heat recovery system Heat pump This device condenses the water vapour inside the dishwasher, and uses the latent heat of the steam to heat the water before it enters the boiler, thereby allowing the installed power to be reduced by 5 kW. It uses an extractor fan to aspirate the steam and two heat exchanger coils with a total surface area of 26 m2; the standard heat exchangers are made of copper, but for applications using osmotic water, special stainless steel heat exchangers are available. In the TopTech rack conveyor, the standard heat...

AutoTimer modules The timer controlled washing system reduces energy consumption during stand-by periods by progressively switching off all the electrical loads except for the heating elements of the wash tank and the boiler, which are controlled by their respective thermostats, so that the dishwasher is ready to resume work at any time. The machine re-starts when a rack is inserted. In any dishwasher, most of the power, water and chemical products are consumed during rinsing. For this reason, our rack conveyors are fitted as standard with a device that stops rinsing if there is no rack present....

User-friendliness Programs The dishwashers are fitted with a series of specific programs for the different conditions of use. The programs differ regarding temperature and power of the wash, the contact time, the temperature, flow rate and rinse distribution. Therefore, differently from most competitor products, limits are not given to just going “quicker” or “slower” but the percentage breakdown of the elements that contribute to washing are really changed, optimising the process in a way to wash greater quantities of tableware more effectively in a shorter period of time. ProSmart Interface It...

All modules have fully opening counter-balanced doors that allow easy access to any point of the washing chamber. This is also valid for the integrated wash and dry module with unique surface; exclusive to Colged. The electric and hydraulic components are accessed for maintenance by removing the front panelling, thus obtaining a completely free surface also in this case. Fully-moulded self-cleaning wash tank, wash chamber without internal piping, doors with insulated and counter-balanced double walls that are very light to lift. Easy to remove and replace wash and rinse arms, module separation...
