Krones NitroHotfill process ensures ‘affordable production’

2 December 2013


Krones claims its updated NitroHotfill process is now the most sophisticated hotfill system on the market, requiring “up to 40 per cent less energy” compared to conventional hotfill processes.

According to the Germany-based company, the NitroHotfill technology enables bottles to be produced by stretch blow-moulding with a minimised weight, without featuring the typical vacuum panels.

Krones has developed the NitroHotfill process over four years in the field, and has made “significant improvements”, such that filling temperatures of up to 90°C are now possible – a particularly significant feature in Asian countries.

“On the Contiform 3 stretch blow-moulding machine, station outputs of up to 2,250 bottles per cavity are achieved, a new high-speed record,” the company says.

The base design of the bottles has also been “substantially improved”.

“In addition to the bases already successfully in use, which permit extremely light container weights of just 15.5 grams for 500ml bottles, for example, there are now flatter, design-optimised bases available, which significantly improve the visual appearance of the bottles concerned,” Krones says.
