    1. Paint: RAL 5009 blue or RAL 7035 white

    2. Documentation and markings: in English language

    3. PLC display and settings: in English language

  5. Feeding Zone

    1. A specially designed feeding zone incorporates a suitable structure fabricated from heavy steel sections to support the conveyor guide rollers and the conveyor centering mechanism

    2. A draw roller is provided to draw the fabric from the trolleys / pallets and overfeed the fabric onto the conveyor

    3. Draw roller drive is derived from a separate inverter controlled AC variable speed motor so as to permit overfeed up to 40%

    4. Unit is designed to feed two / three or more tubes side by side

  6. Dryer

    1. Modular construction, 11.7 meters long dryer consists of 6 chambers each 1.8 meters long and 1 dwell section of 0.9 meter length, delivered pre-assembled for quick and easy installation with closed circuit air circulation system, designed for tensionless drying with a possibility to shrink woven and knitted (tubular and open) fabrics

    2. Each chamber consists of a strong and sturdy steel frame made of standard steel sections

    3. The insulating panels all around insulated by 100 mm thick mineral wool best quality insulating material and suitable for maximum 220°C operating temperature

    4. Top and bottom insulation is with 80 mm thick mineral wool

    5. There is air tight sealing between the panel doors and frame

    6. High efficiency radial blowers made from special steel and dynamically balanced are provided to circulate the air inside the dryer

    7. Inverter controlled AC motor is directly coupled to the blower to avoid loss of efficiency (one inverter per chamber)

    8. One pair jet nozzle element with adequate number of openings for blowing air from both top and bottom of the fabric in each chamber

    9. Equipped with special nozzles connected with main blowers through well designed, closed circuit air circulation system

    10. One duct is provided to deliver air from the heat exchanger to the jet nozzle through the blower

    11. A simple provision is made for nozzle cleaning without removing the nozzles

    12. Necessary conveyor guide rods are provided at regular intervals to support the conveyors

  7. Heat Exchangers

    1. The machine is equipped with an indirect heating system with heat exchangers for heating air

    2. Well designed helically wound finned tube type heat exchangers (one for each chamber) permits maximum heat transfer efficiency

    3. Heat exchangers offered are for high pressure dry saturated steam at not less than 6 / 6.5 bar pressure

    4. Heat exchanger design permits maximum temperature up to 140/155°C with dry saturated steam

    5. All steam and condensate line accessories, valves and pipeline are not included in our supply

  8. Lint Screens

    1. To filter out the lint circulating in the chamber are arranged on the suction side in front of the heat exchangers

    2. The screens can be pulled out for cleaning during the operation of the machine

  9. Adjustment Of Air Flow To Upper And Lower Jet Nozzles

    1. Each chamber is provided with 2 manually controlled dampers to control the distribution of the airflow to upper and lower jet nozzles
