- GF 248 fixed adapter block installed on trolley, with integrated cooling air distribution system
- Additional part for the die: diameter 250 mm, gap 1.4 mm
- Cooling ring Macchi double flow type ASR 3
- With a proven design, this ring made of aluminum allows for excellent cooling and great bubble stability
- The quantity and flow of cooling air are ensured by large vents arranged symmetrically and by a large distribution lung
- The newly designed dual-flow inserts allow low-speed pre-cooling of the material at the exit of the die and final cooling of the bubble with high-speed cold air which, thanks to the Venturi effect, stabilizes the bubble even at high flow rates (In case of line configuration for high neck HDPE production, an alternative will be provided special “L” insert)
- Installed fan power: 15 kW
- Insert range: 250 – 500 mm
- The supply includes:
- Ring body
- 1 set of inserts
- Perforated ring for bubble stabilization
- Fan with AC motor complete with silencer and air filter
- Inverter located in the main switchboard
- Connection pipe to the fan
- Flexible tubes between ring and lung
- The supply does not include the buffer which is supplied with the extrusion head
- The application is for both fixed and oscillating heads
- Internal cooling control (IBC) type JET 6
- Internal cooling system of the bubble which, by regulating the air introduced and the air extracted, controls its diameter
- It consists of a box with a filtering hood containing the fans, easily accessible for cleaning the filters
- The item includes:
- 1 intake fan: 11 kW
- 1 extraction fan: 11 kW
- Ultrasonic sensor for bubble diameter detection
- Iris type air balancing valves
- Galvanized metal pipes for connection to the head (maximum distance 5 m)
- Containment box with air filter
- The caisson also houses the ring fan which is dimensioned together with the cooling ring
- The control panel is integrated into the main panel and includes:
- Motor speed control via inverter
- Fans air flow percentage digital indicator
- Surcharge for 1-sensor ultrasonic IBC system
- It is composed of an ultrasound sensor that detects the diameter of the bubble and consequently regulates the quantity of air being extracted, by controlling an iris-type valve. This type of valve allows finer regulation and therefore greater bubble stability

- Complete with:
- Zone digital thermoregulators
- Pressure gauge (with 2 alarm sets) for each extruder
