Energy saving FREE COOLING is made simple with the hccoils Dry Air Blast Cooler Free Cooling package. Read about how we use cookies and how you can control them in our, Carel IR33 Differential Ambient / Water Inlet Temperature Controller to control Diverting Valve, Volt Free – Free Cooling Active indication, All fitted and wired to the Dry Air Cooler. as a replacement to cooling … To ensure efficient process cooling, a suitable difference in temperatures between the cooling medium and the air within the dry cooler must be maintained. A dry cooler is a cooling device that uses air to achieve process temperature regulation. However, like the differences in a chiller vs heat exchanger, there are significant differences in how dry coolers and chillers function. As the return water is pre cooled by the Dry Air Cooler the load on chiller and power consumption is reduced. The wetted surface – Adiabatic Cooling option enables water to be cooled to within 6 °C of ambient wet bulb, water is used to increase the cooling effect when the ambient dry bulb is 3°C above the design wet bulb – for most of the year the unit operates as a conventional Dry Air Cooler. For a dry cooler, thermal exchange is performed by pulling in external air and circulating it over tubes containing a cooling fluid (typically water or water-glycol mixture). Both a dry cooler and chiller can be used in similar process applications to attain optimal temperatures. Facebook Xing YouTubeLinkedIn Contact Guentner.

All features of temperature control by fan off cycling with low or residential fan speeds are retained. , others require the use of alternative equipment like dry coolers. The very large surface areas of the coils assure that evaporation takes place efficiently with the very minimum of wastage.

The Dry Air Cooler is arranged in series with the refrigeration water chiller,.

As the return water is pre cooled by the Dry Air Cooler the load on chiller and power consumption is reduced.

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. Wetted surface – Adiabatic Cooling enables water to be cooled to within 6 °C of ambient wet bulb, water is used to increase the cooling effect when the ambient dry bulb is 3°C above the design wet bulb – for most of the year the unit operates as a conventional Dry Air Cooler.

The excess heat transferred to the cooling fluid is then returned to the dry cooler and the cycle is restarted. EC Fans are fan assemblies with Electronically commutated external rotor motors with integrated EC variable speed controller. Trust Cold Shot Chillers for Dependable Industrial Chillers, water-cooled and air-cooled chiller variants, How Are Lasers Made? The cooling done by a dry cooler is based on the principles of sensible heat rejection. For the best experience on our site, be sure to turn on Javascript in your browser. FREE COOLING for water cooling applications is achievable for most of the year for many applications using Dry Air Coolers. Dry Air Coolers are mainly used in lieu of wet systems i.e. as a replacement to cooling towers. The outdoor component is the dry cooler whereas the indoor unit is made up of the following parts enclosed together: The benefits of opting for a dry air cooler are listed below: A standard chiller unit is designed to work on one of two principles: vapor-compression or heat absorption with similar components.

The normal dry air cooler is regulated by fan off cycling by thermostat switches; a further thermostatic switch brings on the wetting cycle, only after all the fans are running. A dry cooler is essentially a fluid cooler that uses air, a relatively dry, non-liquid fluid to accomplish process cooling. Reversion back to dry air cooling takes place on lowering of temperature. A typical dry cooling system is designed as a dual unit system comprised of outdoor and indoor aspects linked by a fluid pump. It is important to note that a dry cooler does not have a standard refrigeration unit which chills a circulating refrigerant.

One or more of our units can be selected to give the most cost effective solution to suit your space and noise requirement. This is the basis for the differentiation into water-cooled and air-cooled chiller variants. 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. As with the condensers, our dry air coolers are finned heat exchangers. The cooled fluid is then circulated through a heat exchanger attached to an associated process. Regional weather data analysis shows a typical 120 hours per year when ambient exceed 22 ° C. Description The V configuration Dry Air Coolers can be adapted to take advantage of latent cooling effect in adverse conditions of high ambient dry bulb temperatures. Dry coolers are equipped with fans that pull air from the cooler’s exterior to sustain the heat exchange process. Request a quote from our team today to learn how we can help with your process cooling needs. 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 Depending on operator preference, there are different approaches to industrial cooling. 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. Standard arrangements include flat bed vertical or horizontal airflow with V and W configurations to offer the smallest footprint. While some process temperatures can be optimally maintained using conventional.

The water used for wetting is quite small and is totally lost, not recycled or retained.
