The g-factor is a measure of centrifugal force which has a significant effect on laundry during spinning. g equates to 9.81 m/s² (acceleration as a result of the pull of gravity). A higher spin speed makes for a higher g-force and less residual moisture in the laundry.
The lower the residual moisture in % when the laundry is taken from the washing machine, the less energy is required in the subsequent drying process. In addition to the spin speed, drum diameter also has an impact on the g-force.
Ratio between drum volume and load capacity
In the case of washer-extractors, we recommend a 100 l drum for max.10 kg of laundry. The ratio between dry laundry and drum volume should ideally be 1:10.
For optimum drying of the same 10 kg of laundry, tumble dryers should have a drum volume of 250 l as the ratio between load capacity and drum volume on tumble dryers should be 1:25.
Throughput figures for rotary and flatwork ironers are based on DIN 11902:
Initial residual moisture of 25 or 40% / 46 or 53%, dried to 0%
Bed linen, TB21, i.e. weight density of 175 g/m2 +/- 10 g/m2
Trough temperature of approx. 180°C
Continuous, uninterrupted laundry intake (no gaps)
Width used: 80%
In practice, throughput is usually 20-40 % below the quoted figures. Actual throughput depends on the speed and experience of the operator, the type of laundry being ironed, the way it was sorted prior to ironing, the condition of the trough and the standard of finish required. The figures quoted refer to machines with electric heating.
Information on dishwasher capacity
Plates/h throughput provides an indication on the number of plates which can be processed per hour by a tank dishwasher in the shortest programme. Since loading and unloading times are not taken into account here, this is a theoretical rating but one which is commonly used by all manufacturers.
Information on items/h and cutlery/h refers to freshwater machines. This rating takes all items of cutlery/crockery into account, not just plates (as is the case on tank machines), since freshwater machines have a second basket offering additional capacity.
Prerequisites for achieving these throughput levels are a 65°C hot water supply and a 3-phase 400 V electrical connection.
Information on lab washer capacity
Information on machine capacity represents the maximum load a machine can process per cycle. This may vary, however, depending on the type of load and the mobile unit/inserts used for processing.
