Energy consumption
The actual load is significantly less than the power requirements. This is achieved by energy recovery from the breaking energy of the servo drives. In addition, the idle power of the servo drives (not that of the other drives) is compensated in the Sinumerik.
The energy consumption of both the washing machine and the dryer depends strongly on the temperature settings and on the combination of production rate and workpiece weight.
For ex. tube 76 x 4 x 1,080 mm St37 from master length 12,300 mm with 969 pieces per hour requires a power of approx. 46 kW in the washing machine to warm up the tubes from 20 to 65°C.
This is 7.4 t of steel which must be heated up from 20 to 65°C within one hour.
For ex. tube 20 x 2 x 500 mm ST37 from HL 6,500 mm with 1,743 pieces per hour requires a power of approx. 4kW in the washing machine in order to heat the tubes from 20°C to 65°C.
The maximum heating capacity of the washing machine is 40 kW.
However, only the power to maintain the set temperature is consumed.
The heating capacity of the dryer has a maximum of 33 kW and can be adjusted.
The setting is made directly according to specifications for the air temperature from 0 to 300°C.
Customer feedback indicating that our competitors use less energy can be put into perspective by looking at the individual production capacity in pieces per hour. To heat a workpiece from 20°C to 65°C, the same amount of energy is always required; we just do it faster.

The compressed air consumption may be altered via operator adjustments, for ex. some blowers may not be required.
Operating supplies
Washing agents for WDM
It is not possible to provide detailed information as customers have a wide range of applications.
We use, for example, a ratio of 7% Wedolit K911/Wedolit K102 : 93% water. This corresponds to 100 liters of K911 for one WDM filling (1,400 liters capacity for workpiece length of 2,000 mm). Depending on application this filling lasts 1 to 6 months.
Water consumption of WDM approx. 10 - 100 l/day depending on application
