The most innovative dryer for commercial printing

The Ecoset /T dryer is a hot air web offset drying system that covers the full range of commercial printing from 16 pages up to 96 pages applications. This dryer integrates the functions of drying, afterburning and chilling in one single unit.

The dryer section has an integrated afterburner, which incinerates the solvents from the ink to produce clean exhaust air. The thermal energy gained from burning the solvents is effectively being re-used in the heating process. The chill stand with the proven small diameter chill roll technology eliminates the solvent condensation phenomena that exist on conventional chill stands. By consequence, the web exit temperature after the dryer can be much higher, and no cooling section is required. The result is a significant reduction of the gas consumption, and the absence of condensation risks in the dryers last section.

Integrated chill stand

The integrated chill stand offers unique advantages in the heatset printing process. Silicone applicators are mounted before the first chill rolls, so to prevent ink picking on the chill roll surface. Special chill roll cleaning systems are no longer required. The innovative web guide integrated in the first chill roll ensures optimum web stability in the dryer and after the chill.

Frequently Asked Questions

Below you find the answers to some commonly asked questions about this equipment.

The Contiweb hot air dryers offer an innovative solution for recycling energy from ink solvents to fuel combustion and maintain dryer temperatures. As the air containing evaporated solvents reaches the end of the dryer section, it is directed into integrated combustion chambers for incineration. The exhaust air is then thoroughly cleaned and recirculated back into the dryer section, effectively reusing the existing heat.

One notable advantage of the Contiweb drying process, which incorporates the integrated afterburner, is its significant reduction in energy consumption compared to traditional systems. Depending on factors such as ink coverage and speed, the integrated afterburner can contribute to significant energy savings. This efficiency improvement benefits both cost savings and environmental sustainability.

If you are interested in exploring the possibilities for reducing gas consumption and achieving cost savings with your existing dryer, Contiweb's Gas Reduction Enhancement program offers a viable solution.

Contiweb dryers offer the advantage of being equipped with frequency drives that allow continuous adjustment of fan speeds, ranging from 0 to 100%. In contrast, fans in conventional dryers typically operate at fixed speeds of either 50% or 100% of their nominal speed, often resulting in unnecessary energy consumption. By utilizing the fully variable speed capabilities of frequency drives, the power consumption of Contiweb dryers can be significantly reduced by up to 50%. This not only leads to cost savings but also provides the added benefit of extending the lifespan of motors, motor bearings, V-belts, and fans.

Recognizing that not all printing companies are ready to invest in a new energy-efficient dryer, Contiweb offers an appealing solution known as the Electrical Power Reduction enhancement. This enhancement allows printing companies to achieve substantial electricity consumption savings with their existing dryers.

Contiweb hot air dryers offer a range of benefits, including significant reductions in gas and electricity consumption, as well as lower CO2 emissions.

Through the post-combustion of solvents, Contiweb dryers can achieve remarkable gas consumption reductions of up to 70% compared to conventional dryers. This represents a substantial decrease in resource usage and associated costs. Furthermore, the implementation of variable frequency drives to power the dryer fans allows for electricity consumption reductions of up to 50%. This not only contributes to cost savings but also has a positive impact on CO2 emissions, promoting environmental sustainability. You can get an indication of your potential savings with the Sustainable Savings Estimator.

It's important to note that the extent of cost savings and CO2 reduction achieved will vary depending on factors such as ink coverage and speed. To obtain a precise calculation tailored to your specific requirements, please reach out to the Contiweb sales department. They possess the expertise and knowledge to assist you in determining the potential benefits and conducting a comprehensive cost analysis.

Many governments around the world offer subsidies and incentives to businesses that invest in capital goods aimed at reducing their carbon footprint and promoting sustainability. These subsidies are part of broader environmental and climate change initiatives to encourage businesses to adopt cleaner technologies and practices. The availability and nature of these subsidies can vary depending on the country and region.

Government agencies, environmental departments, or industry associations can provide information on available programs and eligibility criteria. Consulting with sustainability experts or financial advisors can also help navigate the subsidy landscape and identify the most relevant opportunities for reducing the carbon footprint through capital goods investments.
