Sriram Compressors (Coimbatore)Private L Upplipalayam, Coimbatore, Tamil Nadu

Air discharged by any air compressor always contains water vapour, which also depends on the ambient temperature and the relative humidity. When air is compressed, the volume decreases proportionally. This results in condensate formation. Condensate causes corrosion in compressed air pipe line. Compressed air driers are used to separate the condensates. Refrigerated Air Dryer removes moisture from compressed air to the desired dew point temperature. The performance of a dryer is quoted in terms of ‘pressure dew point’, which is the temperature at which water vapour will start to condense out of the air. For example, a dew point of 4ºC at 7 bar (g) (700kPa (g)) means that no water will condense from the air until it goes below a temperature of 4ºC. Working principle: The saturated compressed air enters in air-to-air heat exchanger. Here the incoming hot air is cooled by the outgoing cold air. The pre-cooled incoming air enters in the air-to-refrigerant heat exchanger further reducing the air temperature to specified dew point 2ºC to 4 ºC. The air leaving this evaporator is directed to the cyclone separators and water vapour condensate liquid droplets gets removed automatically by Automatic drain valve.

Aero dynamically designed fan with large blades for higher air flow. Optimal distribution of load on cylinders Forged steel crankshaft assembly supported at both ends for higher dynamic stiffness and least vibrations. Convenient oil sight glass and drain. Efficient air filters. Low expansion aluminium alloy pistons with good quality piston rings for positive sealing at higher temperatures. Air receiver pressure tested to 19 kgs/sq.cm for a working pressure of 12 kgs/sq.cm. Pressure relief valve for extra safety.

Flexible packaging has gained importance as consumers demand greater product protection and longer shelf-life due to better gas barriers and ultraviolet (UV) light protection. Glass is reaching its limits in terms of light-weighting, and there is growing doubt among brand owners about its ability to evolve with market needs. The growing emphasis on the carbon footprint of packaging supply will prove a compelling competitive advantage for plastic packaging. Over the long term, demand is expected to be buoyed also by the improving economics of PET., viz., the growing emphasis on commercial benefits of pack weight reduction. Sriram has developed PET Compressors for PET blowing machines that gives an output of 30 CFM with Radiator and water cooled models.

In many sectors of industry, high quality and extremely clean air is required. Dust, humidity and oil must be removed from the compressed air in order to meet more stringent requirements. One way of treating Air is with the help of Air Accessories like Driers and Filters.   Another way is to opt for Oil free Compressors wherein the Compressors are designed to compress Air without coming into contact with Oil. Oil free screw compressors are so-called dry running units whose compression chamber is not lubricated. The highest precision in manufacture and production ensures efficiency of this type of compression

Companies are now competing in an environment of rising energy costs and the uncertainty of available electricity. Improving the efficiency of Electric Motors and the equipments they drive can save energy, reduce operating costs and improve our nation’s Productivity and Energy Efficiency should be a major consideration for purchase of a Motor. Sriram Electric Motor Production has been focused on this and always in the move in achieving energy efficiency. Motors are constructed with improved manufacturing techniques, superior materials, higher premium grade steel laminations, precision air gaps between rotor and stator good insulation and bearings providing longer lives that lowers heat output all of which increase reliability to accomplish Motors that deliver greater performance while using less electricity.

Water vapour is always present in the air entering a compressor. With a decrease in air temperature and/or an increase in pressure, this vapour will condense. This condensate is often contaminated with oil and solid particles. All condensate must be removed from filters, dryers and air receivers and disposed off. Condensate is collected by installing drain traps (also known as drain valves). These are attached to components where water will condense, such as Air Receivers, Dryers and Filters.

Borewell compressors are used to lift water from borewell and are used for agriculture, housing complexes, factories, hospitals, etc. The system of working of borewell compressors work with a set of pipes, namely air and water pipe. Compressed air is sent into the borewell and this creates a differential pressure within the borewell which raises the water through the delivery water pipe. The alternating piston arrangement of the pump allows the water flow in an intermittent manner.
