Standard arrangements include flat bed vertical or horizontal airflow with V and W configurations to offer the smallest footprint. Request a quote from our team today to learn how we can help with your process cooling needs. Chillers use coolant/chiller fluid which may be cooled by air or water in their associated condenser. The question of causing possible conditions for legionella is no more than that of normal climate conditions of rain. The Dry Air Cooler is arranged in series with the refrigeration water chiller,. For the best experience on our site, be sure to turn on Javascript in your browser. They are preferred by most consultants and end users due to their low profile, low noise and ease of installation. The cooling done by a dry cooler is based on the principles of sensible heat rejection. Dry Cooler vs. Chiller – What Is a Dry Cooler, Depending on operator preference, there are different approaches to industrial cooling. Both a dry cooler and chiller can be used in similar process applications to attain optimal temperatures. Energy savings are immediate when the ambient is 1° C below the return water temperature to the chiller and increase as the ambient reduces to a point where 100 % FREE COOLING is achieved by the Dry Air Cooler. Rather, it uses fans to pull in ambient air to cool its heated fluid medium. The very large surface areas of the coils assure that evaporation takes place efficiently with the very minimum of wastage. Alternatively, units may be selected for cooling water solutions to a temperature below the ambient dry bulb approaching conditions near to evaporative towers. The water used for wetting is quite small and is totally lost, not recycled or retained. A typical dry cooling system is designed as a dual unit system comprised of outdoor and indoor aspects linked by a fluid pump. Whether your application is cooling water / glycol for water cooled chillers, injection moulding machines, furnace equipment, CHP Engine Cooling or any other process. Used to reject heat from air conditioning plant chillers, water cooled variable refrigerant flow units, combined heat power installation, engines, Versatemp air conditioning equipment and a variety of other applications, they cool the water/glycol mix in a closed circuit by passing ambient air over the finned surfaces. The EC Blue Owlet fans are highly efficient – IE4 (IEC60034-31) efficiency class offering the highest efficiency with the lowest possible noise level for any duty. Dry coolers are equipped with fans that pull air from the cooler’s exterior to sustain the heat exchange process. Depending on the water quality it may also be necessary to fit a scale prevention device to the mains water supply. This article will highlight the differences between a dry cooler vs. chiller and help you decide which is best for your cooling needs. The excess heat transferred to the cooling fluid is then returned to the dry cooler and the cycle is restarted. Please fill out the form below. as a replacement to cooling towers. The cooled fluid is then circulated through a heat exchanger attached to an associated process. as a replacement to cooling … All dry air coolers are suitable for outdoor applications, however, special centrifugal dry air coolers are designed for use indoors and in plant rooms. A typical unit requires a cooling medium channeled from an associated process that enters a dry cooler and exchanges accumulated heat with the air circulating within. The water is only needed when the load and ambient dry bulb temperature exceeds a predetermined set point, with very few hours of wetted surface operation over a year. To ensure efficient process cooling, a suitable difference in temperatures between the cooling medium and the air within the dry cooler must be maintained. , others require the use of alternative equipment like dry coolers. All features of temperature control by fan off cycling with low or residential fan speeds are retained. For the best experience on our site, be sure to turn on Javascript in your browser. It is important to note that a dry cooler does not have a standard refrigeration unit which chills a circulating refrigerant. A dry cooler is a cooling device that uses air to achieve process temperature regulation. Energy saving FREE COOLING is made simple with the hccoils Dry Air Blast Cooler Free Cooling package. * Required Fields, Address: 14343 Interdrive East, Houston, TX 77032, Request Product Manual | Privacy Policy | Sitemap | Marketing Provided by MARION Integrated Marketing. Both thermoregulatory tools achieve a similar effect, but their mechanisms operate differently. Dry air coolers. Recommendations We would recommend that the coil fins are polyester coated to minimise any effect of corrosion. In addition they have no legionnaires risk as they are dry systems. © 2020 HC Coils Ltd - All Rights Reserved. A dry cooler is essentially a fluid cooler that uses air, a relatively dry, non-liquid fluid to accomplish process cooling. On the other hand, industrial chillers incorporate refrigeration units (often in conjunction with heat exchangers) in their cooling setup. The benefits of installing an air-cooled chiller or water-cooled chiller in a process setup are listed below: For over thirty years, Cold Shot Chillers has been producing the very best industrial chillers. We offer a wide range of options enabling us to provide the most cost effective solution for your cooling requirement. HC Coils offer Ziehl Abegg EC Blue Owlet Fan options for the complete ranges of Air Coolers, Dry Air Coolers and Air Cooled Condensers. Energy savings are immediate when the ambient is 1° C below the return water temperature to the chiller and increase as the ambient reduces to a point where 100 % FREE COOLING is achieved by the Dry Air Cooler Dry Air Coolers come in various shapes and sizes ranging from the small 1m length coolers to a truck size 13m. Used to reject heat from air conditioning plant chillers, water cooled variable refrigerant flow units, combined heat power installation, engines, Versatemp air conditioning equipment and a variety of other applications, they cool the water/glycol mix in a closed circuit by passing ambient air over the finned surfaces. EC Fans are fan assemblies with Electronically commutated external rotor motors with integrated EC variable speed controller. Therefore with a design ambient of 20 °C wet bulb it is possible to achieve fluid outlet temperatures of 26 °C.
