Evaporative Cooling Systems

Cooling requirements are widespread in both commercial and industrial sectors, and cooling is generally categorized in two ways: process cooling and comfort cooling or climate control. Process Cooling vs. Comfort Cooling/Climate Control Process cooling is applied when a process requires accurate and constant temperature control. Often in these applications, chillers are used to remove heat due to their ability to provide cooling capacity even through changes in ambient temperature, flow requirements, and heat load of the application. Comfort cooling or climate control, on the other hand, regulates temperature and humidity in a space, and is generally simple, used for cooling rooms, electrical cabinets, and other spaces in which temperature does not have to be constant or precise. Air conditioning units fit into this category. What is process cooling? Process cooling, in its simplest form, can be described as the removal of unwanted heat from a process. This is often necessary to ensure the safety and efficiency of said process. Why process cooling? In many industrial processes, heat load is a component that must be carefully controlled. Furthermore, different aspects of the application might require cooling. Key cooling areas include: Direct cooling of a product Plastic during the moulding process Metal products during machining processes Cooling of a specific process Fermentation of beer and lager Chemical reaction vessels Machine cooling Hydraulic circuit and gearbox cooling Treatment ovens Welding and laser cutting machines Within many processes, the integrity of the process itself as well as the final product is incumbent on the precision of heat management. The key facets for a cooling requirement are to: Improve the efficiency of a process Enhance overall quality of finished product Prevent spoilage of product by overheating Increase production speed Prevent overheating Reduce wear and tear on machinery thereby reducing maintenance costs Increase safety of process Why use chillers for process cooling? Process chillers, like Parker???s line of??production process chillers, can be integrated easily into most applications. It uses a refrigeration circuit to remove heat load passed onto the cooling fluid that returns from the application. Process chillers are ideal for efficient cooling due to their ability to operate across a range of ambient conditions at variable loads. Advantages of utilizing process chillers include: Constant, precise control of the process temperature Can deliver cooling fluid directly to the application???s heat source Works independently of ambient conditions Closed-loop water circuit minimizes potential contamination of the process Recirculation of cooling fluid reduces costs and resulting waste Modular design leaves room for expansion opportunities High heat exchange capacity Water is a low-cost, readily available resource within most industries Potential to integrate into existing cooling systems

A Two-Stage Evaporative Cooling System is also called as an indirect cooling system which uses the latest evaporative cooling system technology. This system is more energy efficient than air conditioning systems.

Our Two-stage evaporative cooling technology is having fully automatic control for temperature as well as humidity. Sometimes the delivery room condition is close to 25 Degree Celsius. We have used this system in replacement of air conditioner of large comfort areas, industrial large spaces where air conditioning is not possible, all food processing application where positive pressure is a concern, area which is having a high temp with large volume. We can save the energy consumption by almost 40% with the help of this technology. We are having design & execution expertise which has served these systems for the aseptic area, Industrial kitchen area, packing area, Snacks processing area etc. We will provide you the best solution according to your requirement with the most efficient system for your business.

How Does Two-Stage Evaporative Cooling Work:
Two-stage evaporative refers to the stages of cooling that happens in the process. In the first stage the air passes through a heat exchanger where the air is cooled, during this initial phase the air does not pick up any moisture. In the second stage, the same air passes through a dampened pad where the additional cooling takes place and the air picks up some additional humidity.

Two-stage evaporative cooling system use a pre-cooler, more efficient pads, and more efficient motors, and do not add a lot of moisture to the room as compared to single-stage evaporative coolers. As they are expensive as compared to the single stage coolers they are used in areas where the day temperature exceeds 100°F.

Advantages Of The Two-Stage Or Direct Evaporative Cooling System:

• This technology helps in reducing the cost by conserving the energy and where single-stage evaporative cooling systems cannot be used due to high humidity
• It is cost-effective and consumes half the energy required by an air conditioner and the investment is also relatively quite low.
• Two-stage evaporative cooling systems helps in cooling the conditioning space by 100% fresh air and are designed for 25-40 air changes per hour which are quite similar to ventilation. It is an eco-friendly cooling system as no refrigerants are used.
