®AQUA-BLEND AB SERIES

The AQUA-BLEND ABSeries SNG Venturi BlendingSystem provides a fuel directly

compatible with natural gas. It is

specifically designed for small to

medium-large capacity ‘base load’ and

industrial Standby Systems applications.

The design is based on a single skid

configuration combining the AQUA-

GAS® Vertical Gas Fired Waterbath

and a VAPOR-JET® LPG/Air Venturi

Blender.

During operation, an LPG fired

atmospheric burner heats a glycol/water

‘waterbath’ in the vaporizer. Liquid LPG

enters the vaporizer’s helical process coil

and is heated by the waterbath and

induces vaporization. The LPG vapor

then passes out of the vaporizer’s heat

exchanger area into the vaporizer’s

external vapor header. The vapor exits the

header and passes to the venturi blender.

In response to the pressure of the

LPG/Air in the surge tank, a solenoid

valve opens allowing vapor to pass

through the venturi assembly and

inspirate the required volume of air to

mix with the LPG vapor.

This single skid design is Factory

Mutual Approved, pre-piped, pre-wired

and pre-tested at the Factory. It is safe,

simple and proven. The AQUA-BLEND ®

remains a wildly popular choice for small

to medium-large capacity NGconsumers

including manufacturing companies,

bakeries,institutions and other similar

applications.
