Options
- Additional LN2 feed line : standard length is 3 meters from tank to doser. Any additional meter should be ordered in this option. Bayonet couplings will be needed in case of lengths longer than 12 meters.
- A standard 6 meter cables set from the doser to the PLC is included. Instead, a 15 meter set can be ordered optionally.
- Profibus communication utility between doser and filler
- Encoder with 10 m cable & shaft coupling (bracket not included). Shaft coupling for 10mm shaft sizes Amount of containers/revolution to be specified.
- Additional languages for HMI and operation manuals upon request. The following languages are standard : English, German, French, Spanish, Italian.
Specialties
- LDV (Low Dose Velocity) heater block e.g. for hot fill applications (P/N : 56882)
- CIP heater block: automatic nozzle protection (P/N : 52850)
- The HF-LDV (Hot Fill-Low Dose Velocity) Heater Block (P/N : 61137)
- Combi LDV/CIP heater block: combines both benefits of the LDV and CIP heater block (P/N : 55300)
Installation
- Stainless steel (height adjustable) support in AISI 304 material (also available in AISI 316 on request). This support can be either on a 2×2 pod or a bottom plate basis.
