With the new HASCO Cooling Tornado, HASCO is providing an innovative solution for increasing efficiency and saving energy during the cooling of the mould.
The Cooling Tornado Z9665/… offers a variety of application possibilities and can be used both in combination with runners in core cooling systems and directly in the corresponding cooling bores. Through the production of a turbulent flow, the effectiveness of the cooling is increased by up to 20 % (depending on the flow l/min). This turbulence interrupts the laminar lower layer of the cooling medium and has the effect that also the inner core of the cooling medium flows to the outer sheath, and thus considerably improves the heat transfer.
Turbulent flow for efficient cooling
The Cooling Tornado allows, through the turbulent flow, efficient cooling for shorter cycle times and the avoidance of hot spots, which ensures uniform temperature distribution. Compared with conventional cooling bores, temperature differences of up to 10 °C can be attained. The turbulence of the cooling medium leads to an energy saving of between 20 and 40 %. The Cooling Tornado allows easy retrofitting as well as the possibility of customised shortening, making for uncomplicated installation on existing systems.
The installation itself is also extremely simple. The Cooling Tornado can be quickly retrofitted and is simply positioned and fixed at the end via a clamping ring. The mounting can both be carried out in combination with cooling pipes such as Z962/… for core cooling and also directly mounted in the cooling bores.
Energy saving directly in the mould
Extensive tests confirm the effectiveness of the Cooling Tornado Z9665/…. In a comparison of the cooling circuits with and without the use of the Cooling Tornado, a reduction in the surface temperature of 10 % was measured. With a flow rate of, for example, 6 l/min, the surface temperature of the cavity fell from 86 °C to 78 °C. These results show that, by fitting the complete mould with the Cooling Tornado Z9665/…, an energy saving of 20-40 % can be achieved.
