Brooks DLI Vaporizer System
May, 2016
DLI Welded (DLIWx)
The DLIWx Series vaporizers (see Figure 1-1) are an integrated system
which combines Brooks Instrument's proprietary atomizer along with a
welded 316L SS recirculating heat exchanger that is wrapped in band
heaters and insulation inside an aluminum enclosure and mounted on an
aluminum back plate.
Brooks' proprietary atomizer exponentially multiplies the specific surface
area of an inlet fluid by creating millions of 2 - 5 micron size droplets
through the use of a supersonic shock front caused by the rapid
expansion of a carrier gas through an orifice. Increasing the fluid's surface
area improves the heat transfer efficiency. The 316L stainless steel
atomizer, with removable orifice, is a fully-serviceable, interchangeable
component sized for the desired fluid and mass flow rate.
The heat exchanger, with its highly effective heat transfer design, quickly
and efficiently vaporizes the mixture of micron diameter droplets and
carrier gas. The consistent control of both temperature and pressure
conditions inside of the heat exchanger ensures that incoming liquid
droplets are not only efficiently vaporized but remain in a vapor state and
don't recondense. The heat exchanger assembly is a completely welded
assembly, utilizing all 316L SS components.
• Wetted Materials: 316L SS with Viton or Kalrez seals
• Dual K-type thermocouples: one for operating temperature and one for
over-temp limit
• Removable atomizer & exit orifice(s) are sized to the desired operating
conditions
• Resistive band heater(s) 200-5000 Watts
• Insulation jacket
• Powder-coated aluminum cover
• Variety of process connections: tube stub; tube compression; face seal

DLI High Capacity Vaporizer (DLIHV)
The DLIHV Series vaporizer (see Figure 1-2) is an integrated system
which combines Brooks Instrument's proprietary atomizer along with a
heat exchanger that is wrapped in a silicone foam insulation jacket inside
an aluminum enclosure and mounted on an aluminum back plate.
Brooks' proprietary atomizer exponentially multiplies the specific surface
area of an inlet fluid by creating millions of sub-10 micron size droplets
through the use of a supersonic shock front caused by the rapid
expansion of a carrier gas through an orifice. Increasing the fluid's surface
area improves the heat transfer efficiency. The 316L stainless steel
atomizer, with removable orifice, is a fully-serviceable, interchangeable
component sized for the desired fluid and mass flow rate.
In certain cases where a carrier gas is detrimental to the process
conditions, this model has the capability to flash vaporizer the liquid
precursors. See a Brooks application engineer for more specifics.
The heat exchanger, with its highly effective heat transfer design, quickly
and efficiently vaporizes the mixture of micron diameter droplets and
carrier gas. The consistent control of both temperature and pressure
conditions inside of the heat exchanger ensures that incoming liquid
droplets are not only efficiently vaporized but remain in a vapor state and
don't recondense. Depending upon the heater size, the DLIHV can reliably
