ITMA ASIA 2010Power Frame Stenter Eco- Heat Eco- Air

Initiatives

POWER-FRAME stenter

New Generation StenterHighest PerformanceMinimum energy consumptionSplit flow SystemPatented Venturi nozzle: optimum mixture of

circulating and fresh airHomogenous air distribution : alternating air flow in

the thermo zones.Robust and low-maintenance chains

POWER-FRAME stenter

Save Hard cash with ECO Heat

Heat the fresh air or water by exhaust air

1. Air to Air : Heat of exhaust gases is used to heat the fresh air It can reduces process heat demand by 12 to 15% In case of dry heat setting it is upto 30%.

2. Air to Water: Water can be heated up to 900C Can be used directly to process/boiler feed water.

zones

Electro static filter system

Offers air filtration in two stages through:Ionization Zone Collection Zone

This system filters air with 99% of efficiency

Available with integrated automatic cleaning unit

More efficient than devices only with ionization zone

Available in several sizes

High removal efficiency for aerosols and noxious gases

Low cost of operation

Robust design in stainless steel

Compact dimensions

Easy maintenance with compact filter modules: easy to remove and easy to clean

Advantages of Eco – Air

Temperature inside stenter 2200CExhaust Air Temperature 1400CHeat recovery system can recover 700C

Energy saving of up to approx. 20 %with 140°C dryer temperature

Energy saving of up to approx. 35 % with 190°C dryer temperature

Eco – Heat Statistic

Lucky Tex domiciled in KarachiOwing weaving mills, finishing, dyeing and drying

facilities as well as stitching unitTotal capacity of 225,000 meters /dayThree Bruckner Power Frame Stenters installed at

Lucky Tex for drying and heat-setting of woven fabrics Lucky Tex has installed ECO-HEAT back-pack – heat

recovery air/air integrated into the top of the dryer Integrated into the roof of the dryer Annual costs associated with stenter operations,

almost 60% of total annual costAlmost 25% cost reduction with a Bruckner heat

recovery

Case Study : Lucky Tex Processing Mill, Pakistan

Case Study : Lucky Tex Processing Mill, Pakistan

Bureau of Energy Efficiency (BEE) is implementing a BEE-SME Programme to improve the energy performance in 25 selected SMEs clusters

Pali Textile Cluster is one of them

Today there are over 350 units in Pali

Production of all of these combined together crosses 5.5 million meter per day

Energy account for 30% on total cost

Project Report On Installation Of Waste Heat Recovery System In Stenter at Pali

Electricity consumption for stenter alone in textile dyeing and processing units , 50%

Over 20% for electricity consumption

30% fuel consumption in power process industries

Pay back period of less than one year
