Model ULTRA -Dryers

ULTRA Low Energy - Operating Cost Savings

• A process running at 220lb/h (100kg/h) can typically see a kW difference of 41 Watts/lb (92 Watts/kg) with ULTRA dryers versus generic desiccant dryer.
• This saves $6,500 annually at an example rate of 220lb/h (100kg/h) - whilst doing the exact same job.
• ULTRA delivers savings year on year for its full life cycle.

ULTRA Low Energy - Dynamic Software

• Temperature Sense Control – temperature is controlled efficiently with energy saver as standard.
• Heater and air flow are automatically regulated to ensure only the required amount of heat and air flow are used to bring material up to temperature.

ULTRA Quick Drying

• ULTRA dryers place materials under vacuum to dry rapidly, versus long exposure to desiccant hot dry air flow.
• Normally, ULTRA dries material 6 times faster than conventional desiccant dryers.
• ULTRA fast drying time provides quicker start-ups.

ULTRA Low Energy Components

• No regeneration process, no added energy used.
• ULTRA uses only one smaller blower and heater sized for smaller volumes and faster drying times.
• Compact heating hopper – less material in process, less energy used, easier cleaning. 
• Minimal maintenance – no scheduled maintenance requirements and no consumables.

ULTRA Live Throughput Monitoring

• Load cells monitor the vacuum chamber and retention hopper and provide live materials usage data.
• Data allows the drying rate to efficiently follow and adjust according to the dryer consumption rate.
• ULTRA live data makes for ULTRA efficient drying.

ULTRA Fast Return on Investment 

• ULTRA dryers quickly pay-back in the short term and continue to provide energy reduction cost savings in the long term.
• Energy usage - one Desiccant day = one ULTRA week.
• Indirect benefits - increased productivity, reduced start-up scrap rates and reduced energy usage for the same time period.

ULTRA low energy dryers operate in a three-step process:

1 – Heating Hopper

• HEAT - The heating hopper is loaded with raw material and heated to the normal drying temperature for a short period of time. Examples: 
  • For ABS typical HEAT time is 15 to 30 minutes at 176 °F / 80 °C.
  • For PET typical HEAT time is 40 to 60 minutes at a drying temperature of 338 °F / 170 °C.

2 – Vacuum Chamber

• Hot material is released into the vacuum chamber, the amount monitored by load cells and adjusted automatically.
• DRY - The vacuum chamber is sealed and a high vacuum is applied to the hot material, dropping the boiling point of moisture to 133°F / 56°C.
• Vacuum is 56"Hg / 700 mmHg, typically for 20 to 30 minutes, depending on the material, initial / target moisture and required throughput. 
• Vacuum only active usually 1-2 mins per cycle - minimal energy. 

3 – Retention Hopper

• The retention hopper is mounted on load cells monitoring materials usage live.
• Live usage data indicates when to release material from the vacuum chamber, adjusting material in process automatically. 
• Optional dry air purge - only for very hygroscopic materials.
