HTI Spectra HE™ Ultra Drying System

HTI Spectra HE™ Ultra Drying System
Order no.: A02-0037

HTI SPECTRA HE™ Ultra Drying System organizes oscillating flows in the ultrasonic range into one powerful stream and directs this stream onto the material,through penetrating the laminar boundary layer above high-speed webs.

It is an advanced convective drying technology for inks, adhesives, water and other solvents.

The HTI SPECTRA HE™ Ultra Drying System consists of:

  • 1 (per color) dryer station
  • 1 (per color) heater
  • One or more blowers
  • 1 control panel



Increased Web Speed
Our ability to dry faster has made it possible for some customers to increase web speed by 50 to 70% without compromising quality.

Reduced Energy Consumption
When compared to the conventional drying system, the HTI Spectra HE Ultra uses only a fraction of energy (to 75% less). It is an energy source independent system - it can use natural gas or electrically preheated air.

Increased Press Performance with Water Based Inks and Coatings
If drying of water based inks is a challenge for your operation, the HTI solution is better at removing moisture than currently available drying techniques. Therefore we broaden the use of water based inks.

Drying Without an Increase in Temperature
Our drying technology is more effective at the same or lower temperature than the current drying solution, as the temperature and mass transfer is greatly enhanced by the oscillating vibrations in the ultrasonic range of air flow.

Environmental Benefits
Reduced energy consumption and increased use of water based inks benefit the environment, at the same time reducing costs, an important criteria for selecting a printing company.

HTI’s Spectra HE™ Ultra Drying System is compatible with many different basic material types:

  • Films / Foil
  • Plastic (Credit Cards)
  • Paper / Cardboard


HTI’s Spectra HE™ Ultra Drying System is compatible with many different printing processes

  • Rotogravure
  • Offset / Flexoprinting
