Steam Jet Heaters, in-line, are used for both once-through and circulating heating duties. They can either be employed on a once-through basis (type L), to raise the temperature of a liquid by up to 95oC in a single pass, or on circulation systems (type H or system Ciba-Geigy), to raise the temperature of a circulating stream by up to 30oC per pass. With a standard-type heater design (type L or type H), turn-downs of 5:1 are the norm., but if a more sophisticated system is required, with much closer temperature control, with the GEA Steam Jet Heater "System Ciba-Geigy", the turn-down can be as much as 200:1.

Steam jet heaters "L" for installation in pipelines
Application
Steam jet heaters are used to heat liquids by means of direct condensation of steam.
The steam condensate mixes with the liquid.
Steam jet heaters, type “L” are used in passage and circulation heating systems.
The achievable heating per pass amounts to max. 90 °C.
Steam jet heaters "H" for passage and circulation heating systems
Application
Steam jet heaters are used to heat liquids by means of direct injection of steam.
Steam jet heaters, type “H”, are used in passage and circulation heating systems:
- heating to max. 30 °C per pass
- steam flow control range up to max. 5:1
Cast iron EN-GJS-400-18-LT (GGG40.3)
Application
Steam jet heaters are used to directly heat a liquid with heating steam.
Steam jet heaters, “System Ciba Geigy”, are used in passage and circulating heating systems and for batch processes:
- flow rates of 2-700 m³/h
- heating per pass up to approx. 30 °C
- control range of heating capacity up to 200:1
- heating up to approx. 5 °C below the saturated steam temperature of the heating steam
