NitroJection Processing Unit (NPU)
The NitroJection Processing Unit is a stand-alone, portable, gas assist
controller which intensifies and injects high pressure nitrogen into molds
through either NitroJection’s patented gas-assist nozzles or In-Mold Pins. The
NPU is available with one, two or four outlets. The NPU features seven stages
of digitally controlled nitrogen injection pressures per outlet. The 8" color
E-Z touch screen allows for operator input of timing, pressure profiles, and
recipe storage. An Automation Direct Programmable Logic Controller ( PLC )
monitors and controls the unit. New features include auto purge, remote outputs
and independent start signals to allow gas injection to multiple presses. The
NPU includes an internal booster and a high pressure receiver. The system will
intensify up to 10,000 psi maximum system pressure.
Power- 110 vac
Air supply- 90 psi minimum
Nitrogen supply - 220 psi minimum up to 2050 psi maximum
Molding machine signal(s) - Mold Closed, Purge Guard, Injection / ram start- 24
NitroJection Satellite Unit (NSU)
The NitroJection Satellite Unit is specifically designed for gas-assist molders
with an existing source of high pressure nitrogen. If the molder requires a
means of high pressure, the Nitro Booster System can be used to operate from
The NSU without an internal intensifier is designed to
control the timing and pressure profiles of the high pressure nitrogen during
the gas injection cycle. The system requires an external source of
high-pressure nitrogen up to 6000 PSI and appropriate connections to the
molding machines. The NSU is available with one, two or four valves to allow
gas injection through a machine nozzle or independently into multi cavity molds
using an In Mold Gas Pin.
The NSU features fast acting TESCOM electronic regulators which accurately
control the gas injection pressures. An Automation Direct industrial PLC and 8"
color touch screen allow for easy operator input and monitoring of the gas
assist process. Additional features include auto purge cycle, remote outputs
and independent start signals to allow gas injection to multiple presses.
5000 psi minimum incoming nitrogen gas supply
110V AC single phase
Optional electrical requirements are possible
The Nitro Booster System provides a compact, portable source for high pressure
nitrogen gas required by gas assist injection molders. This air driven booster
package is supplied fully assembled, tested and ready for turn key
installation. The Nitrogen Booster is designed to receive regulated nitrogen
(500 PSI min) from cylinders and intensify the pressure up to 6000 PSI. The
final output pressure is controlled by an adjustable mechanical pressure
switch. All that is required is plant air, 100 PSI and regulated nitrogen
Output pressure up to 6000 PSI
Pneumatically Driven Gas Booster - requires shop air 100 PSI & Nitrogen 240
PSI up to 2200 PSI.
Control Panel includes: Inlet Pressure, Outlet Pressure and Drive air pressure
Air and Nitrogen isolation valves, System vent valve.
