Double Stage Air Washer Air washer machine is utilizing the natural process of water evaporation along with an air moving system to create effective cooling. The ambient air is pulled through filters and it passes through the cooling pad then it cools the air through water evaporation. A blower circulates the cooled air throughout a suitable ducting and grill network arrangements. Advantages of Air Washer Low installation cost, Low running/operation cost. Effective in high heat generation areas. Easy & inexpensive maintenance. Healthier System - Since it works on 100% fresh air. Technical Explanation of Double Stage Air Washer In the single stage Air-washer humidity level rise to that level that makes occupants uncomfortable because 6ltr. of water evaporates to give us the cooling effect of 1tr. Double stage Air-washer do not produce humidity level as high as that produced by single Air-washer. In the first stage of a two stage Air-washer, warm Air is pre-cooled indirectly adding humidity by passing the warm Air through the heat exchange that is cooled by passing cold water which is pre cooled by the evaporation process. The pre cooled Air then passed through a water soaked cellulose pad where it picks up the humidity as it cools. Since the air supply is pre cooled in the first stage so the less humidity is transferred in the second stage to reach the desired cooling temperatures. The result is cooled air with a relative humidity between 55%-70% while single stage Air-washer produces above 75-85% of RH.

Dehumidifier Dehumidifiers regulate humidity by removing excess moisture from the air, thereby creating living conditions that are inhospitable to dust mites, mold, and other allergenic organisms. What is the mechanism that allows it to take moisture that’s in gas from the air, and remove it liquid water. While there are two primary methods or styles that allow dehumidifiers to remove moisture from the air. We’re focusing on the most popular style - refrigerant based dehumidifiers. How Does a Dehumidifier Work? The mechanics behind a refrigerant-style dehumidifier are actually quite simple. Notice how moisture forms on the outside of your cold glass of water on a hot day? That's condensation, and once you know that, understanding how a dehumidifier works becomes a lot easier. Room dehumidifiers, work much like air conditioners; warmer, moist air enters the dehumidifier and then crosses refrigerant cooled coils, causing the moisture in the air to condense on coils within the machine. Much like your glass of ice water, the coils are colder than the air immediately around them. As air cools, it's ability to hold and retain moisture drops, and when the air has more moisture than it can hold, it forms that familiar condensate. The condensate then collects in a drip pan or bucket for disposal while the now cooled air passes back over the dehumidifiers warm motor to that it is slightly reheated before being discharged back into the room. By being slightly warmed, the air exiting the dehumidifier is dry and warm - which means it will attract moisture like a magnet and maximize the dehumidifier's efficiency. Benefits of a Dehumidifier Improve/regulate product quality By maintaining the right temperature and humidity during the production process, you can prevent product stagnation and/or loss and considerably improve the quality of your product, for instance by preventing fusing/sticking of hygroscopic substances and products. Prevent condensation Open products should be shielded from condensation. Condensation can also damage equipment. The risk of condensation is especially high in cooled spaces or in spaces with a high humidity level (as a result of production processes). An industrial dehumidifier can solve these problems. Prevent fungal and bacterial growth Air drying is the best way to prevent the growth of fungi and bacteria in places that are warm, have a high humidity level and are badly ventilated. Prevent corrosion Corrosion often causes health risks (such as support structures collapsing), as well as high costs. Worldwide, about 5 ton of steel is lost to corrosion every second. Industrial air dryers can prevent the corrosion of metals in vulnerable spots, such as bridges and turbines, and improve the durability of materials.

  Water Cooled & Air Cooled Chillers Water cooled chillers and air cooled chillers are refrigeration systems used to cool fluids or dehumidify air in both commercial and industrial facilities. Chilled water has a variety of applications from space cooling to process uses. How Water Cooled & Air Cooled Chillers Work The cycle begins in the evaporator where a liquid refrigerant flows over the evaporator tube bundle and evaporates, absorbing heat from the chilled water circulating through the bundle. The refrigerant vapor is drawn out of the evaporator by the compressor. The compressor then “pumps” the refrigerant vapor to the condenser raising its pressure and temperature. The refrigerant condenses on or in the condenser tubes, giving up its heat to the cooling water (or air). The high pressure liquid refrigerant from the condenser then passes through the expansion device that reduces the refrigerant pressure and temperature as it enters the evaporator. The refrigerant again flows over the chilled water coils absorbing more heat and completing the cycle.  

Spot Cooler Spot Cooling is portable air-conditioning that can be placed where you need it the most. A Spot Coolers unit can be moved from room to room or positioned strategically to cool “hot spots” in your offices or building - areas that require consistent temperatures. While energy costs continue to climb utility companies are frequently unable to provide all of the electricity that a plant, laboratory, hospital or office complex may require. When circumstances force your business to control capital expense, the case for spot cooling gets stronger - as spot cooling provides efficient, low-cost cooling that is easy on the bottom line. For many industries and companies, in a wide variety of applications, Spot Coolers are the answer to controlling both energy use and capital expenses. Spot cooling is a method of cooling overheated areas within a larger area, as opposed to providing general cooling by means of a remote centrally controlled air-conditioning system. In operation, spot cooling is an extremely efficient means of cooling people, processes, and equipment because it directs a localized stream of cool air exactly where it is needed. The concept of spot cooling is not a new idea, but the use of Spot Coolers to accomplish localized cooling within work environments and equipment rooms is an effective solution to many difficult cooling problems.  

  Panel Air Conditioner Panel Air conditioner utilizes closed loop design to maintain clean and cooled air in electronic panel. To achieve this two entirely separate air circulation circuits are provided in Panel Air Conditioner. One circulation circuit sucks hot clean air from down of electronic control panel in to panel air conditioner and after passing it across evaporator of Panel Air Conditioner becomes cooled and dehumidified. Same cooled and dehumidified air is supplied to electronic control panel from top of the Panel Air Conditioner. The second circulation circuit makes use of ambient air to remove heat out of condensers and then to atmosphere from panel air conditioner. These two air circuit are separated by a partition in Panel Air Conditioner to ensure closed loop design and to keep electronic components of control panel away from dust and humidity present in factory shop floor.
