In simple terms, Instantaneous Jet Heaters (IJH) use steam to heat a liquid stream.
Pressurised cold liquid is introduced to the IJH and is immediately accelerated through the combining nozzle, resulting in a local pressure drop.
Pressurised steam enters the IJH and is discharged into the liquid at high velocity, via a number of jets around the combining tube. This method of combining steam and liquid prevents ‘backing up’ should the steam be under a much higher pressure than the liquid.
Both the sensible and latent heat of the steam is fully dissipated within the liquid, making Transvac’s instantaneous jet heaters very efficient.
Our IJH’s are also designed to combine the two streams, silently and instantaneously to prevent undue noise and wear normally associated with steam ‘collapse’.
