Denross NE

Headquartered in Lewiston, Maine, Von Mehl Company, Inc - Denross group offers unique solutions for cleaning and coating of assets exposed to severe conditions.

Specializing in the Pulp and Paper Industry. We offer soda blast cleaning, dryer cylinder cleaning, surface preparation and coating of paper machinery and structural steel. 90% of the work we do is in Pulp and Paper mills.

Because we specialize in Pulp and Paper our crews are very familiar with working during shut downs and the absolute necessity of completing our work on or before the indicated deadline. We have never held up the start up of a mill because our work was not completed.

Safety is our first priority and our record is outstanding, we have never had a lost time injury.

We would welcome and appreciate the opportunity to review your particular project needs and offer our recommendations.

Denross NEDryer Cylinder Cleaning System

The Denross automated system ensures even, accurate cleaning of the dryer cylinder shell.

Cost effective bicarbonate of soda (baking soda) is environmentally responsible and more efficient than other cleaning methods.

Soda blasting dust is exhausted through the dryer hood exhaust fans. Heavies are swept up

With downtime at a premium, one set-up can often accommodate the cleaning of two or three dryer cylinder shells.

Systematic cleaning during regular maintenance shutdowns proves to be most effective.

Dryer cylinder cleaning can be accomplished during planned short shutdowns as well as extended maintenance periods or down days.

Why bicarbonate of soda?

Delivered under pressure using compressed air and soda blasting equipment, the nontoxic, water soluble baking soda crystal physically removes coatings, soils and contaminants from the paper making process from the substrate. Because of its relative softness and friability, the crystal disintegrates on impact without distortion of the dryer cylinder or shell.

We also use the soda blasting system to clean the frames of the paper machine after mechanical scaling prior to coatings application.

When it comes time to insulate a steam lines, tanks or dryer heads we offer our Nansulate thermal insulating products, no longer will the expense of CUI (corrosion under insulation) be a worry.

Energy costs can be reduced by insulating areas that in the past had been impractical.

Nansulate is a patented nanotechnology based line of coatings that utilize a nanoparticle that has a very low thermal conductivity. The coating acts as a liquid thermal insulator that can be applied to many different surfaces types, including buildings and equipment,

to inhibit heat flow through the material.
