Reactor Cooling for Chemicals


A different degree of control

Sometimes, having control over your chemical manufacturing process is all about finding the right temperature. If you have a need for efficient heat transfer and very low-temperature cooling in your chemical processes, we can offer you a variety of systems to help you do just that. KEMCOOL® D, KEMCOOL® N, and direct injection reactor cooling systems can be used for a wide range of applications including cooling fluids in reactors, crystallizers, lyophilizers, storage vessels and other process equipment. All reactor cooling systems are specialized to meet your unique needs for chemical manufacturing, and our dedicated staff will work with you to find the system that provides the optimum results for your business. 


Rivoira's cryogenic low-temperature fluid-cooling technology provides significant advantages over conventional cooling methods. The KEMCOOL® D system uses a proprietary non-freezing injection system to cool fluids with liquid nitrogen by direct contact.

Direct Injection Cooling

By injecting cryogenic nitrogen directly into the reaction, heat is rapidly removed. This helps lower batch time and reduce by-product formation. For example, we helped a leading chemical manufacturer reduce batch cool time (from room temperature to -40°C) from four hours to one. And our ability to help maintain consistent production environments with temperature variations of less than 1°C greatly enhances productivity by reducing by-product formation. The key to this technology is our process control, efficient solvent recovery system and innovative injection nozzle designs.


If direct contact with the cryogenic fluid is undesirable due to contamination or other limitations, we also offer KEMCOOL® N non-freezing heat exchanger system. KEMCOOL® N system uses a proprietary heat exchanger to cool a process or heat transfer fluid. This reactor cooling system allows spent nitrogen to be recovered for reuse elsewhere in your chemical manufacturing facility. Benefits include additional refrigeration for the reactor, lower costs than conventional cooling, unlimited reaction temperatures and viscous process fluid handling.
