Deaerators

JET-VAC designs and manufactures vacuum systems for use with vacuum deaerating equipment. Vacuum deaeration is used at temperatures below the atmospheric boiling point to reduce the corrosion rate in water distribution systems. The JET-VAC vacuum system is applied to the deaerating system to bring the water to its saturation temperature to reduce dissolved gasses, particularly oxygen, to low levels.

Liquid Ring Vacuum Pumps

Liquid Ring Vacuum Pumps (LRVP) by themselves are limited in the depth of vacuum they can generate by the vapor pressure of the sealant liquid at the process temperature. However, when used in conjunction with steam jets much deeper vacuum levels can be achieved.

JET-VAC designs and manufactures steam jet vacuum systems that integrate LRVP. These systems are called “Hybrid Steam Jet Vacuum Systems” using a combination of steam jets and LRVPs. While we don’t offer our own brand, we partner up with proven reliable manufacturers

Condensers

Condensers are an integral part of a steam jet vacuum system. They are used to reduce / remove condensable components from the process stream. This results in a smaller more economical system and reduces overall steam consumption.

condenser internals
There are two basic condenser types:
Barometric
A direct contact exchanger where the cooling water mixes directly with the process vapors. This is a very efficient design although consideration must be given to the cooling water outlet steam as it will contain condensables from the process stream
Indirect
A shell & tube exchanger where cooling water passes through one side (tube side) and the process vapors the other side (shell side). This type of exchanger while not as efficient as the barometric style does not have any of the process stream condensables mixing with the cooling water.

JET-VAC designs and manufactures condensers per the Heat Exchange Institute (H.E.I.), Tubular Exchanger Manufacturers Association (TEMA), and ASME Section 8, Division 1.
