WAREWASHINGRack-Type DishwasherPROFI CNEFFICIENT – RELIABLE – INNOVATIVE1economyENERGY-MANAGEMENT EFFICIENTA conventional rack-type dishwasher loses 40 % of theenergy available in the machine via the exhaust system. Thedistribution of water and the air stream have a considerableinfluence. The new energy-management EFFICIENT reducesthe evaporation loss. The improved arrangement of thewide angle nozzles FAN and the orientation of the washarms reduce the air flow within the machine. The patentedwide angle nozzle FAN spreads out a 65 % wider and moreeven spray pattern. Therefore the recirculation of watercan be reduced for the same wash result. In order tokeep the system in balance less air/water steam has tobe exhausted. The new energy-management reduces theenergy loss of the rack-type dishwasher by up to 15 %.DETERGENT SAVING SYSTEM LOW-CHEMWith the optional detergent saving system LOW-CHEMdetergent is injected directly into the wash tank, which iscontinuously regenerated by fresh water from the rinse.Therefore detergent is added to maintain the concentrationaccording to the added regeneration volume. The enhancedLOW-CHEM detergent saving system directs only 105 liter offresh rinse water into the wash tank for regeneration. Aheadof the final rinse, detergent is flushed off the wash ware bythe RADIUS pre-rinse nozzle and diverted back into the washtank. The dosing of detergent depends on the regenerationwater volume. As a result detergent consumption is reducedby up to 70 % compared to conventional systems.HOBART HEAT RECOVERYHOBART‘s heat recovery system functions according tothe countercurrent principle, using the energy from theextracted air to heat up the incoming water. The energyexchange takes place in the HOBART high-performancecondenser. At the same time, the extracted air is cooleddown and dehumidified. The HOBART heat recovery systemreduces energy consumption by up to 6.3 kW and totalconnected load to 29.6 kW. 1) The extracted air can be leddirectly into the building‘s ventilation ducting. 2)HOBART HEAT PUMPTHE HOBART heat pump uses the residual energy in theextracted air following heat recovery. A compressor andrefrigerant are used to ensure efficient heat recovery. Theamount of recovered energy is sufficient to heat the washand rinse water. This innovative technology reduces energyconsumption by up to 10 kWh and total connected load to20.0 kW. 3) The temperature of the extracted air is reducedto approx. 20 - 24°C. 4) The extracted air can be blowndirectly into the room. 2)1)Calculation example for the PROFI CN S-A-DS, C20 compared to models withoutheat recovery2)Conditional on compliance with VDI 20523)Calculation example for the PROFI CN S-A-DS, CHP compared to models withoutheat pump4)Values in continuous operation +/-10 % depending on incoming air in the roomand inlet temperature of the fresh water (values based on 10°C incoming waterand 23°C ambient air temperature)EFFICIENT – OPTIMALECONOMICAL – EFFICIENTUp to 65 % wider andmore even spray pattern.The HOBART heat pumpuses the residual energyin the extracted air.
