Is dampening fluid filtration a practical technique or a trap?

“Even we are all surprised! With our Zen10 dampening fluid filtration system officially launched in 2015, more than 40% of our customers are replacing the existing water tank filtration system. What makes us even more shocking is that these The average filtration time of the replaced filtration system is less than one year!” said an insider from REX Rui Lixin (formerly Bell New Technology), a professional dampening liquid system company.

Since 2014, the catastrophic deterioration of the natural environment has caused the government and all walks of life to focus on environmental protection and green development. The standards and charges for pollution discharge are also increasing. This has made the environmental protection concept of printing filtration and emission reduction from the previous concept of advocacy to almost the height of the printing company's life and death.

Ideal: For the main source of sewage in the traditional offset printing process, the filtration reduction of dampening solution has become the first problem that many printing companies hope to solve. A large number of printing companies launched various dampening liquid filtration equipment and systems in 2014/2015. We look forward to seeing the improvement of printing quality, saving dampening solution and reducing waste water discharge in the sales staff. Liquid system maintenance and many other beautiful sights.

Reality: However, after using it for more than half a year, and after a few months, many Indian companies found that the beautiful scene seems to exist only in the salesperson’s brochure picture. After spending the initial honeymoon period, each The so-called dampening solution filtration system can no longer provide satisfactory filtering effect, even if it is not used on one side, and the printing machine water tank is restored to the turbid state, the oil is scattered, and even the quality of many printing presses is greatly affected. The big impact, there is a serious dirty version.

Is dampening fluid filtration a practical technique or a beautiful trap?

Is dampening fluid filtration reduction an illusory bubble? Even a technical trap?

In fact, dampening solution filtration reduction has existed and developed in Europe for nearly 10 years. It has a complete theoretical system, and experimental demonstration has led to the development of a scientific dampening solution for filtration. That is to say, the dampening solution filtration reduction itself is completely scientific and can be perfectly realized. For example, Germany's Elbo ELPOTEC launched a dampening fluid filtration system in Europe 10 years ago, and it is used in a large number of offset presses such as Heidelberg , Roland and KBA in Europe. Taking a Heidelberg CD102 five-color offset printing machine as an example, the professional dampening solution filtering and abatement equipment can save more than 200L of dampening solution every year, reduce the discharge of dampening solution wastewater by more than 7500L, and improve the printing machine working efficiency by nearly 1.5 million sheets/year. .

At present, the commonly used dampening solution filtration and emission reduction system in the Chinese market has not achieved the expected effect or even has a negative impact. The reason can be summarized as a bit of a mouthful: in China, not all of them are called 'damping solution filtration system'. Dongdong is a true dampening solution filtration system! In other words, many devices in China that claim to be dampening fluid filtration are not really a dampening solution.

At present, the more professional dampening liquid filtration systems in the Asian and Chinese markets mainly include RE10's Zen10, Zen15 series, Elpotec's TF2, TF4 series and so on.
