Steam Jet Heaters

Steam Jet Heaters Overview

Steam Jet Heaters utilize the principal of direct injection to mix steam with a cold liquid uniformly. Operation is efficient because the heat in the steam is absorbed by the liquid being heated to approximately 10% of liquid saturation temperature. The jet action produces agitation and circulation, eliminating the need for other equipment to accomplish these functions in most applications. In operation, jet heaters use steam (or steam and water under pressure) as the motive force to entrain, mix with, heat, and pump (or circulate) the suction liquid.

Steam Injection Heating


Steam Jet Heater Types

Continuous Heater
(made for direct connection to water and steam lines and to mix steam with cold water and discharge hot water under pressure)
Simplex Heater
(combines liquid under pressure with steam at a higher pressure)
Slurry Heater
(simple pumping of semi-solids to process applications involving reactions caused by addition of steam)
Quiet Heater
(mixes steam, atmospheric air, and water to reduce the noise and vibration associated with tank heating by steam)
Sparger Nozzles
(recommended for use in cases where it is desired to start heating from a shallow level and made for threading in sparger pipe installed along the bottom of tank)
Circulating Heater
(recommended for use where heating and strong directional circulating action in open tanks are required)
Direct Contact, High Capacity, Multi-Spray Steam Heater
(suitable for very large quantities of hot water; designed to prevent flooding, and to heat water close to the steam saturation temperature)
Direct Contact, High Capacity, Counter-Current Steam Heaters
(water and steam flowing in opposite (counter) directions and operate effectively with internal pressures above and below atmospheric pressure)
Direct Contact, High Capacity, Continuous Steam Heater
(heat a liquid under pressure with steam by direct contact and should not be used if air and other non-condensables are present)
