Acid Flushing for Chill Rolls

A Critical Maintenance Service for Liquid Filled Rollers

Over time, liquid-filled heat transfer rollers can become clogged with coagulated chemicals, rust or mineral deposits. These foreign substances lead to low flowrates and poor thermal transfer, affecting your manufacturing processes.

With Menges’ Acid Flushing Services, coagulants and oxidized particles are broken down and flushed out of the roll.

Acid flushing is recommended as a once-per-year preventive maintenance service. Annual acid flushing prevents unwanted compounds from building to high levels, which might damage the roller or impede thermal transfer.

Rush and priority turnaround times are available to minimize downtimes.

So speak with a Menges Engineer about acid flushing services – to keep your chill roll cold and your hot roll hot.

Menges Roller offers acid washing services for liquid-filled industrial rollers, for hot and cold applications, and this service works to restore thermal transfer rates and reduce oxidation.

The result of not acid flushing. This badly oxidized chill roll required a full rebuild.

ACID FLUSHING SERVICES:

  • Breaks-down & flushes mineral deposits, rust, coagulated chemicals & oils
  • Menges uses specially-developed cleansing compounds
  • Acid flushing should be completed annually
  • Maintains good flowrates & proper thermal transfer rates
  • Can be compined with chrome re-plating or other services
  • Appropriate for hot or cold-application rollers
  • Rush & priority turnarounds available, to minimize roller downtime
When acid flushing services from Menges are applied to chill and heat transfer rollers, rust and scale are removed, which improves laminating and adhesive curing.

This inner shell was removed as part of total roll rebuild, mainly caused by a lack of regular acid flushing services.

Acid flushing services for chill rollers are provided by Menges Roller Company in northeast Illinois, available for paper mill rollers and chill rolls for extruded film, as seen here.

All this is what gets trapped inside the roller when it’s not acid flushed. This roller required a full rebuild.

   
When acid flushing services are purchased from Menges Roller Company, plant mangers can expect increased fluid flow and improved thermal transfer rates on evey type of liquid-filled roller.

1 – Initial Flushing. This is typically what we see when acid flushing begins. Sludge like this is harder to remove the longer it sits in the roller, which is why we recommend annual acid flushing maintenance.

Acid washing services from Menges Roller are helpful in removing calcium deposits and coagulate thermal transfer fluids, especially important for nonwovens and geosynthetic material processors.

Day 2 – Menges will flush your roller for up to 3 days. This duration is necessary to break-down the mix of hardened debris particles. The output color changes as different chemicals & materials are flushed out.

When acid flushing is not completed, processors see poor cooling and heating results in liquid filled chill rolls, which is why Menges Roller provides this valuable service.

Day 3 – Rust, calcium deposits, and industrial oils are notoriously difficult to break down, which is why we continue the process for several days. Here, on day 3, we’re seeing a reduction in particulate matter.

The final results of acid flushing services from Menges Roller company generate optimized thermal transfer for chill rollers and heated rolls, as seen in this image.

The Result – After 3 full days of chemical baths, high-pressure washes and continuous flushing, we have positive results. When conducted annually, acid flushing maintains uniform thermal transfer & extends roller life.

SPEND A LITTLE NOW – SAVE IN THE LONG RUN !

Acid flushing can save you from expensive chill roll rebuild and  replacment costs.

Like any good maintenance service, spending a little now saves money in the long run.

Debris & scale result in poor flowrates and uneven thermal transfer, on both hot and cold rollers.

Annual acid washing prevents debris buildup in the first place, maintaining optimum heating & cooling.
