Winterhalter has introduced a compact conveyor dishwasher model called the CTR Energy.
The unit is designed to minimise consumption of energy, water and chemicals, which in turn reduces running costs. It should operate steam-free to create a better working environment in the kitchen.
The CTR Energy’s modular design allows it to be retrofitted with a variety of optional components, such as pre-wash and drying zones, as a kitchen’s demands and practices change. The compact design means the main wash unit is as little as 1,400mm long and 800mm wide, but can handle up to 195 racks per hour, producing consistently hygienic results.
The key energy saving feature is said to be the dishwasher’s exhaust air heat recovery, which uses the energy from the steam produced by the machine to pre-heat the cold inlet water. This should reduce energy consumption, lower operating costs and improve the kitchen climate, since instead of escaping into the kitchen, the machine’s steam and heat gets captured and recycled. Because there should be less waste heat, there should be less work for the ventilation system to do, which further reduces the kitchen’s energy use.
The CTR Energy also included ‘rack-controlled zone activation’. This means that the various zones of the warewasher (pre-wash, main wash and rinse) are only activated when a rack enters the zone. No rack means no activation, conserving power, water and detergents, which should lower energy use and reduce running costs during quiet periods.
Plus the unit has a smart rinse water system that automatically adjusts the volume of water intake, depending on the current speed of the conveyor, so that it only uses as much water as is required. In tests, this was claimed to cut water consumption by up to 50%, to as little as 130 litres per hour.
The CTR Energy is designed to be simple to operate and, at peak times, the system allows the user to change the settings, so that the machine can be switched between highest possible energy savings or highest rack capacity.
