Application Flexibility Nortec Industrial Fluid Chillers High Performance Better Efficiency State-of-the-art Technology Flexibility of design and product adaptability sets Nortec apart from the rest in the industry. Each unit is individually designed and manufactured to meet your exact specifications. Chillers are available from 0-00 tons capacities with user selectable cooling - Air cooled or Water cooled, and with single, duplex or multiple refrigeration circuits. A long list of available options helps you choose the components needed for your application. Quality engineering and manufacturing is the key element of our flexibility. Why You Need a Chiller? Equipment Protection The most compelling reason for a chiller is the continuous protection it provides to your valuable process equipment. It represents a small fraction of the investment, yet it extends the life of your equipment by many years. Increased Production By maintaining a constant cooling temperature in the production process, the speed and accuracy of parts produced is greatly enhanced. You may ask yourself: "Does my equipment shut down during summer months?" A water tower may provide adequate cooling during fall and winter months, but fail during the summer months. A water chiller will immediately eliminate this problem. Save Water and Related Costs With today's environmental issues and limitations, even the use of 0 gallons of city water per minute (. million gallons of water per year) - will be a significant addition to your manufacturing costs. With the use of a Nortec chiller, you will not only eliminate this cost permanently but you will not have any environmental issues to worry about. By doing a cost analysis, you will be surprised to realize how quickly a chiller ends up paying for itself and then saving you money for years to come.

Nortec Advantages Nortec Industrial Fluid Chillers The performance of any chiller depends on the quality of its key components. Nortec uses the best available compressors, condensers, evaporators, pumps and controllers. With accurately designed and sized components, the chillers are manufactured to provide years of trouble free operation. Rotary Screw Compressor Semi Hermetic Reciprocating Compressor High Efficiency Scroll Compressor Depending on the capacity and application, one of these three types of high quality energy saving compressors are used on Nortec machines. High Efficiency Scroll Compressor Semi Hermetic High Performance Piston Compressor Semi Hermetic Energy Saver Screw Compressor Open Drive Rotary Screw Compressor. Air Cooled Condenser Water Cooled Condenser Evaporator Air cooled condensers are constructed from high thermal efficiency copper tubes, coils and aluminum fins and are rated for 00 0 F ambient temperature. Water cooled condensers are designed according to ASE standards with carbon steel shell and copper tubes to provide adequate cooling capacity that exceeds the refrigeration demand. All Nortec water cooled units are equipped with head pressure control and energy saver water regulating valve. Fluid chill evaporators are either shell-and-tube type or brazed stainless steel plate type and are designed for high heat transfer efficiency. Each refrigeration zone has its own independent evaporator, so failure of one refrigeration compressor will have no effect on the other circuits. Pump Nortec closed coupled and base mounted centrifugal pumps provide economical performance for a wide range of applications of varying flow rate and head pressure. (Flow rates up to 500 GP and head pressure up to 0 feet). These high quality pumps meets low net positive suction head pressure requirements (NPSHR) without sacrificing efficiency. The large seal chamber provides a wide fluid passage for maximum cooling of the seal face and allows debris and gases to be flushed away.
Nortec Industrial Fluid Chillers Controller Nortec uses the state of the art controllers for optimizing the performance of these chillers. PLCs (Programmable Logic Controller) are designed with ease-of-use in mind. Their modular and versatile features make it suitable for various applications including local and remote display. Close monitoring of the supply water temperature and total control of the chiller operation allows the user to receive the highest performance from the chiller. Two methods of unloading help achieve optimal stability during variation in heat loads while maintaining constant outlet temperature and minimizing power consumption. Units that use multiple compressors monitor the outlet temperature to determine the independent unloading of each of the compressors. This energy saving feature ensures optimal energy usage and decreases the compressor wear and tear. Optional PC connections are also available.
