Application Transvac's range of Instantaneous Jet Heaters provide a simple, low cost and reliable method of heating reactor jackets. Efficient heating is ensured because the steam comes into direct contact with the liquid and both the sensible and latent heat of the steam are fully dissipated. Transvac Heaters are designed to perform this operation silently to prevent undue noise and wear normally associated with steam 'collapse'. There are two options available:- - An atmospheric system for product temperatures up to approx. 85oC.
- A pressurised system for temperatures in excess of 100oC. The pressurised system can also be used as a reactor jacket cooling system.

Principle of Operation Pressurised water is introduced to the Heater and is immediately accelerated through the combining nozzle, resulting in a local pressure drop. Pressurised steam enters the unit and is discharged into the liquid at high velocity via a number of jets around the combining tube. This method of combining steam and liquor prevents 'backing up' should the steam be under a much higher pressure than the liquid. The two streams combine and mix intimately, fully condensing the steam silently and instantaneously.
