| | Application Overview
All of Transvac’s products for the food industry are designed specifically to suit each application. They are easy to operate, have no moving parts and are virtually maintenance free. Their simple design makes them suitable for C.I.P. cleaning. Units are designed to meet the current hygienic standards with 316L stainless steel being the standard material of construction. Connections can be RJT, Tri-clamp, IDF or similar. 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. |
Jet Heater
|  Jet Heater System | Construction Construction is tailored to suit each application with either single units or complete system available. Proprietary and recognised codes of practice are used including ASME, PD5500, Stoomwezen, etc. Designs comply with the latest European standards and units are CE marked where applicable.
Typical materials of construction include carbon steel, stainless steel, hastelloy, PTFE etc. Connections include flanged, screwed or hygienic. |
