Hasco America’s Cooling Tornado is engineered for boosting efficiency and conserving energy directly in the  during cooling. It works in a variety of applications and can be used both in combination with runners in core cooling systems and directly in the corresponding cooling bores.

According to the company, the Cooling Tornado produces a turbulent flow which improves the efficiency of the cooling by up to 20% (depending on the flow l/min). This turbulence interrupts the laminar lower layer of the cooling medium and also has the effect that the inner core of the cooling medium flows to the outer sheath, and thus improves the heat transfer.

This efficient cooling enables shorter cycle times and avoidance of hot spots, which works to ensure uniform temperature distribution. Compared with conventional cooling bores, temperature differences of up to 10°C can be attained, the company says. In addition, the turbulence of the cooling medium leads to an energy savings of between 20 and 40%. 

The unit offers simplified installation and can also be quickly retrofitted. It is simply positioned and fixed at the end via a clamping ring. The Cooling Tornado also enables the possibility of customized shortening, further supporting uncomplicated installation on existing systems. 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.

The company says extensive testing confirms 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 6 l/min, for example, the surface temperature of the cavity fell from 86°C to 78°C. It is said these results show that, by fitting the complete mold with the Cooling Tornado Z9665/..., moldmakers can achieve energy savings of 20-40%.
