ڱǷ®

The IJ̳ ڱǷ® Heat Exchanger is uniquely designed and engineered to handle difficult heat transfer applications. IJ̳ created the Heliflow to be exceptionally versatile, yielding heat transfer rates that can be more than 40% better than typical shell and tube designs. The Heliflow Heat Exchanger encompasses a spiral coil, comprised of multiple parallel tubes mounted within a casing. The case/coil construction creates a spiral flow path providing true counterflow. Each application is specially engineered for an optimal balance of thermal and hydraulic requirements, resulting in maximum heat transfer efficiency. High pressure, specialized materials, cyclic operation, temperature extremes and other conditions can be handled without a problem. The IJ̳ ڱǷ® Heat Exchanger has years of proven service, in thousands of applications throughout the world, with high quality performance always guaranteed.

Surface Condensers

By producing a vacuum at the turbine discharge, condensers increase the overall cycle efficiency. IJ̳ has more than 85 years of design and fabrication experience in the steam surface condenser field. Our knowledge allows for an expedient, accurate design and fabrication process. Using design methodologies and practices that have been honed over time, we work closely with our customers to evaluate options that best meet each project’s objectives.

IJ̳ Steam Surface Condensers range from small packaged units used in the HVAC industry to large cylindrical condensers used for mechanical drive applications in power plants, refineries, or chemical processing plants. Circular shells approximately 12 feet in diameter can be supplied to suit various requirements. Due to shipping restrictions and costs, larger applications are provided in modular rectangular designs where the tube bundles and dome sections are joined at the job site.

Because of our considerable experience in condenser manufacturing, and our ability to work with exotic materials and turbines with different exhaust configurations (down, top, axial), IJ̳ can closely work with customers to evaluate options that best meet the specific requirements of any project.

Process Condensers

A properly designed IJ̳ Condenser between the process and vacuum producing equipment will yield significant advantages. The use of a process vacuum condenser can permit significant reduction in the size of the vacuum producing equipment. A condenser can recover for reuse valuable product that�s carried from the process with non-condensable gases. It can reduce the amount of wastes produced by the vacuum system and lower the process operating cost. IJ̳ Process Condensers can be designed for a wide variety installations: direct contact or surface type, mounted horizontally or vertically, freeze condensation or conventional condensation type.

Matching the Process Vacuum Condenser with vacuum producing equipment is the best way to meet the process objectives. IJ̳ manufactures both the Process Condenser and the vacuum producing equipment. This single-source responsibility provides a unitized system that is matched to the process.

Liquid Ring Vacuum Pumps

IJ̳ liquid ring vacuum pumps are efficient and easy to maintain because there is only one rotating part. Our pumps are robust and can be started and stopped repeatedly, being fit to handle unexpected process upsets, including liquid in the suction, without damage. The exhaust gas stream is oil-free and low temperature.

IJ̳ Liquid Ring Pumps can be fabricated in any material to meet the requirements of the process gas. In addition to operating to very deep vacuum levels, our Liquid Ring Pumps can also operate above atmospheric pressure to provide a very wide range of operation. While liquid ring pumps typically operate with water as the service liquid, IJ̳ Pumps can operate with any liquid that is available.

The IJ̳ Liquid Ring Pump is a proven design, with installations throughout the world. IJ̳ has an extensive database of actual performance test data and can provide a Liquid Ring Pump suitable for nearly any application.

IJ̳ has been providing Engineering Answers since 1936 and can easily combine IJ̳ Liquid Ring Pumps with other IJ̳ equipment, including Steam Jet Ejectors and Process Condensers, to provide a highly efficient vacuum system that optimizes capital and operating costs.

Ejectors

Steam Jet Ejectors – the largest vacuum producing devices available – are used in the most demanding of applications. Virtually maintenance-free with no moving parts, they can be fabricated from almost any material, and can be used in every industry that requires vacuum. Ejectors can be designed to operate without steam as their pressurized (motive) source. In addition to operating well into the micron HgA range, they can also operate well above atmospheric pressure.

IJ̳ has mastered Steam Ejector design. Featuring proven, unique internal geometries and tightly tolerance-controlled steam nozzle configurations, IJ̳ ejectors produce very low steam consumption and highly efficient operation. As an experienced provider of Engineering Answers since 1936, IJ̳ maintains the most comprehensive database of actual steam ejector performance information available today.

Combine IJ̳ Steam Jet Ejectors with other IJ̳ equipment, such as Process Condensers and Liquid Ring Pumps, and you have a single source of supply and a responsible, total solution for process equipment needs.
