Construction and method of Operation
The heater is used to heat a liquid directly by the direct injection of steam. The steam condensate mixes with, and thus heats the liquid.
Inside the heater is a condensation nozzle, which is, in principle, a cylinder with holes drilled in it. This nozzle allows the steam to pass into the liquid to be heated.
In most cases it is the process requirements which dictate the necessary temperature control. Once this is determined, the required steam jet heater can be selected.
Type L : minimal control required
Type H : moderate control required
