Fluidized Beds

Our

Custom Fluidized Beds

The PYRO-STRIP™ fluidized bed cleaning system offers the most efficient thermal cleaning in the shortest amount of time. This allows more frequent fixture changes per work shift and greatly increases the efficiency of the painting or powder coating system.

The process also strips reject parts, castings, and assemblies from shelving to shopping carts. The exceptional energy efficiency of the process is due to the absorption of the thermal energy given off by the combustion of the organic matter or coating that further heats the media as the product is being stripped or cleaned.

The

Pyro-Strip™ Tank System

With the PYRO-STRIP™ Tank System, the abrasive action of fluidized sand joins extreme temperatures to clean your hooks and racks in record time economically! Fluidized sand cleaning is the method of choice for its economical and ecological excellence. The equipment being fabricated is a proven technology with safe and simple operation, and robust construction required for hard working paint lines. Steel, iron and bronze parts can be stripped, as well as aluminum for recycling. Invigorating hot sand bath vaporizes paint, powder coatings and crusty ash residue in 1/6 the time of conventional burn-off furnaces, without the post cleaning clean-up.

Compressed air mixed with gas fluidizes the calibrated quartz sand, burning and scrubbing the residue from the product. The organic residue itself acts as fuel, reducing the amount of added gas necessary to complete the combustion of the coatings. The vaporized residues rise to the surface of the sand, where they are further incinerated in a bed of flame. In this combustion zone, oxygenation raises the temperature to nearly 1600 degrees F. The purified flue gasses rise into the Post-Combustion chamber and are expelled. The unit can be equipped with an optional entegra cyclone separator for further cleansing of the flue gasses.

Fluidizing Bed Operation

The parts are loaded into a basket that is then hoisted into the tank where the fluidized hot sand scrubs and burns off the organic material and vaporizes it without damaging or warping the work pieces. The cleaning cycles take from 20 to 40 minutes at a temperature of 800 to 850 deg. F. The time cycle is regulated by the mass of the load and amount of organic material to be removed. The basket of cleaned parts is lifted with the hoist out of the tank and set to cool. The work pieces in most cases may be ready to use on the line with little or no post-cleaning, depending on the coating build-up and process parameters. The bubbling action of the sand removes most loose ash coating from the surface.

Fluidizing Bed Process

The Pyro-Strip™ fluidized sand tank system utilizes a special compressor to fluidize the calibrated quartz sand inside the tank. The fluidizing air, premixed with the combustion gas, then burns on the surface of the sand bath by a constant burning pilot. The combustion gas supply is modulated in accordance with the heat energy generated by the burning of the organic materials, which is absorbed by the sand, thus reducing fuel consumption.

In addition to the regular burner output, the combustion system is designed with enriche booster combustion for the initial ten minutes of the cycle. This enrichement further incinerates the smoke and fumes generated in the intial heating of the product. The burner is controlled ON/OFF by the temprature controller for an additional program time cycle of approximatly ten more minutes for complete incineration of the organic matter. The balance of the time of the stripping cycle is the fluidizing action of the sand dislodging the residues from the product. The program timers are set for the general cycle requirements for the priducts being processed.

Energy Saving Design

Pyro-Strip™ is 100% environmentally safe, and 500% more efficient than conventional methods. The PYRO-STRIP™Fluidized Sand Tank System is a European design being fabricated in Chicago, employing American equipment standards and domestically available components. The unit is available with either the low profile lid or the H-C lid which allows the entire basket to be loaded and the lid closed prior to fluidizing the sand, thus eliminating any escape of smoke into the plant. Pyro-Strip™machines are fully tested before being shipped to their final destinations where our technicians supervise installation and train your staff.
