MAXIMATOR ® Dosing system with automatic throttle in special design
Type DSD500 with 2 boosters model DLE30-75-2-GUC to increase the
capacity to 27 kg/h of CO2

The dosing system is a self-contained operational unit.

The system consists of:
· 2 pces. Gas boosters
· Proportional valve
· Mass flow regulation
· Automatic throttle
· Switch-over device

Function principle
This dosing system for inert gases DSD500 permits the exact proportioning of inert gases in an
extruder or other plastic processing machines. The DSD500 consists of a booster system with
two gas boosters and a mass flow regulating device. The mass is measured very exactly and
independently on pressure, temperature and type of gas. A high dynamic regulating valve
adapts the dosing automatically to the pressure conditions inside the extruder or the injection
molding machine.

Main characteristic features
· Exact mass flow regulation for all inert gases, independently on pressure and temperature conditions
· Automatic adjustment to the extruder pressure the extruder reduces start-up processes
· A high dynamic regulating valve reacts in shortest time to process changes
· Easy operation via PLC
· Automatic throttle

Advantages when using technical gases as agents
· Physically and chemically inert
· Environmental friendly
· Low gas consumption during foaming
· Cost efficient

The gas is compressed to the required pressure by means of a MAXIMATOR gas booster.
The maximum pressure is limited to 500 bar.
Example: Booster ON 400 bar / Booster OFF 480 bar
When using CO2 from cylinders with ascending pipe, the MAXIMATOR booster as a piston
pump would reach an essentially higher flow capacity.
The mass of the gas is regulated through a 3/3 proportional valve. The pressure difference is
kept via throttle at a constant level.
