Many industrial processes require heating media temperatures between 400 and 600°F. Media choices are organic heat transfer media in vapor phase, organic transfer fluid, or steam from water. The disadvantages of organic media in deodorization applications are well-documented: even traces of the fluid in edible oils are unacceptable in food processing and food additive applications. Water is the safest medium for heat transfer in many cases. The deodorization market is eliminating the use of thermal fluids in food grade applications and gravitating toward high pressure steam heaters.
The NUK high pressure steam generator is a vertical down-fired heating system that combines the best features of a steam system with the safety and efficiency of an organic vapor system. The need for feed-water systems, flow control devices, blow down separators, steam traps, or condensate return pumps is eliminated by the use of a hermetically sealed, closed loop system. After commissioning, this design requires little maintenance and rarely needs additional water.
