Caloris Engineering White Paper on MVR Evaporator Upgrades Now Available

Discusses High-Speed Compressor & Turbofan Replacements for Improved Reliability and Performance

Easton, MD—Caloris Engineering has a new white paper available, “MVR Evaporator Upgrades: High-Speed Compressor & Turbofan Replacements for Improved Reliability and Performance,” which explains the risks of older equipment and the solutions available thanks to advances machine designs and evaporation technology.

Evaporators are widely used in the process industry for concentrating liquids. A great number of evaporators use the technique of Mechanical Vapor Recompression (MVR) for efficient delivery of the heat for evaporation. These MVR Units include specialized rotating machines (either high-speed compressors or turbofans).

Evaporators with MVR Units were installed in processing facilities for food and dairy, ethanol, sweeteners, pulp and paper, wastewaters and other aqueous fluids throughout the 1970s, ’80s and ’90s. The useful life of these MVR Units is roughly 25 years. Consequently, any of these original MVR Units still operating today have well exceeded their useful life. This has implications for unit functionality, efficiency and safety.

MVR evaporator upgrades have proven very effective in helping facility managers reduce maintenance costs, improve evaporator performance and reduce safety risks associated with antiquated compressors and turbofans. Caloris can help facility managers develop a cost-effective plan to upgrade their MVR Evaporator now, before a catastrophic failure occurs.

Evaporators incorporating MVR for concentrating liquids continue to be critically important for a wide range of industries.

The compressors and turbofans comprise the heart of the MVR design, and after 25 years of daily operation, may be approaching a significant hardware failure. Such an event frequently disables a processing plant for a lengthy amount of time. These failures also have been known to cause serious injury to personnel.

“Facility managers should consider the risks and make plans now to develop an MVR Evaporator upgrade plan,” said Caloris President & CEO Jim Peterson. “The good news is that better options now exist for replacing aging or obsolete MVR Units, including capacity increases. Caloris can offer these options.”
