> Air compressors: - Leakages monitoring - Reduction in working pressures - Reduction in number - VSD control for ef ciency improvement
Of all compressors - Higher ef ciency compressors - Air Compressor replacement to High ef ciency - Select the rst use high ef ciency air compressor
> Air conditioning & chillers: - Reduction of energy loss in Air conditioning system - Eliminate chiller use in the hand tufted area. - Higher ef ciency air conditioners - Use the air conditioner does not impact on the environment
> Steam boilers: - Boiler replacement for increase ef ciency by
Combustion control economizer blow down heat
Recovery water injection and EMS. - Maintenance improvement - Reduced steam working pressures - Insulation improvement of steam pipes & equipment - Steam & condensate recovery - Combustion ef ciency control - Higher ef ciency boilers - Water injection for increase combustion ef ciency
> Energy used control system: - Exhaust humidity control on dryer. - Energy conservation controller for air compressors. - Energy used control system. - High Ef ciency Weaving Machine. - High Ef ciency Dyeing Machine.
