The Navis PlanaTex brand Gas Infrared Pre-dryer is used to evaporate moisture from a textile web by radiant heat. Normal radiant burner surface temperatures range from 650°C (1200°F) to 1000°C (1830°F). At 735°C (1350°F), the water is driven off quickly producing an efficient drying method.

Typical Applications

1. Dyeing Applications - Thermosol Dye Ranges and Pigment Dyeing on Tenter frames
2. Production / Speed Increase on existing Tenter frames

The Navis PlanaTex Products pre-dryer design has 2 burners offset per row. Burner rows are offset to prevent direct radiation from one burner to opposite side burner. Each row is modular and can be stacked up to 4 modules and/or be placed side by side.

Figure 1 shows a typical installation of two stacked modules in a 2 pass configuration.

Navis PlanaTex Products uses an advanced combustion technology metal fiber burner that is:

1. Resistant to shock loads – Can be dropped or hit without damage to the burner, virtually indestructible
2. Thermal Shock loads – Heat, cold, or liquids does not affect the burner durability
3. Low Thermal Inertia – Allows quick heating and cool-down, eliminates the need to rotate the burner when stopping, simplifies operation and maintenance
4. Low NOx and CO emissions – In radiant combustion mode, NOx emissions are below 10 ppm at 0% O2
5. Easily modulated – Can be operated at selected firing rates and temperature

Each Pre-dryer pass includes:

1. 1, 2, or 3 burner modules
2. Top mounted exhaust port
3. (2) Teflon coated water cooled rolls
4. Pre-piped gas train
5. Burner ignition & safety system
6. Electrical control panel

Each system includes:

1. Exhaust fan with controls
2. Combustion blower with controls
