Tunnel 50 Twin GT: the perfect integration for your automatic packaging machine

Tunnel 50 Twin GT was designed to be perfectly incorporated into the packaging machines of the Pratika range. The Schneider Electric electronic and electric components finally allow you to control every heat shrinking aspect. Connecting the shrink tunnel to the Pratika automatic packaging machine allows you to control all the parameters directly from the machine’s touch screen.

With its dual heating chamber with separate adjustment and fan speed and temperature control, the exceptional thermal insulation, the high transition and shrinking speed, this tunnel is the ideal machine to provide a highly effective solution to any packaging requirement. The new plastic conveyor belt, ideal for high temperatures, guarantees greater stability for the products and less wear.
