New-Manufacture · Indirect Thermal Sludge Dryer
Built complete. Shipped ahead of the field.
The Denver-Sala Holo-Flite D24-24-6 dries municipal and industrial sludge by indirect thermal conduction — heat moves through a jacketed 316 stainless shell and hollow screw flights, never through open flame contact with the product. Built new, shipped complete, FOB Canby, Oregon.

The Machine
Inside the D24-24-6
A single hollow-flight screw runs the length of a jacketed 316 stainless shell. Thermal fluid circulates through the jacket and through the flights themselves — heat conducts into the product through steel, never through flame. Product and heat travel the same length on separate paths.

How It Dries
Heat and product, on separate paths
-
Feed
Sludge enters through the inlet hopper, one continuous charge.
-
Indirect Dry
Thermal fluid conducts heat through the 316SS jacket and hollow flights — never through flame.
-
Discharge
Dried cake exits the same pass — no second system, no rehandling.
- Indirect Conduction
- Heat is transferred through the steel walls of the trough and screw, not by direct contact between flame and sludge. The product never touches a combustion source.
- Closed Thermal Loop
- Thermal fluid circulates through the jacket and through the hollow flights of the screw itself, delivering heat along the full length of the pass in a closed circuit.
- 316 Stainless Contact Surfaces
- Every surface the product touches — shell, screw, flights — is 316 stainless steel, specified for the corrosion chemistry of municipal and industrial sludge.
- Continuous Conveyance
- A single screw moves material from inlet to discharge while conduction does the drying — mechanical transport and thermal transfer happen in one pass, not two systems.
Schedule
The field-built quote, and the one that ships
Field-fabricated indirect dryers are quoted in field-crew seasons. The D24-24-6 is new manufacture, built and shipped complete from Canby, Oregon — the field-fabrication wait comes off the schedule.
Schedule bars are illustrative, based on typical field-fabricated lead times versus new-manufacture delivery. Confirm exact delivery date at contract signature.
