Résumé : |
Climate protection is still on the global agenda, even if its relative importance has changed recently in the public perception. Many so-called “low carbon footprint technologies” are already available and could be utilized immediately in plastics processing. But what carbon reduction measures are not only environmentally effective? Using practical examples, gwk shows how the use of efficient temperature-control technology rapidly pays off economically, too. |

- Potential in temperature-control with centrifugal pumps
- A comparison of investment and energy costs
- The bigger the pump, the bigger the potential savings
- Fig. 1 : Differences in power consumption and quantity ratio
- Fig. 2 : Comparison of the characteristics of the pump types (pressure/delivery). The greater pump performance, the greater the energy advantge in favor of the centrifugal pump
- Fig. 3: Comparison of heating strategies : direct heat transfer wins out thanks to high heating rates in a small space, sustained high efficiency, a low weight and amodest isulation requirement, as well as the possibility of small heating performance gradations and easy mechanical cleaning
- Table 1 : Comparison of the investment and energy costs of temperature-control equipment with small pumps in the performance range up to max. 40 l/min flow rate
- Table 2 : Comparison of the investment and energy costs of temperature-control equipment with medium-sized circulation pumps in the performance range up to max. 120 l/min flow rate
- Table 3 : Comparison of the investment and energy costs for the low-cost unit. In the illustrated example, the payback time of 2.5 years is reduced to only 0.2 years with support from public funds. In this case, too, a possible carbon tax leads to savings in the operating costs |
