Preface

General

The Adjustable Pressure Phase Separator (APPS 160) unit
is used to lower the saturation point of liquid nitrogen

Liquid nitrogen saturated at a high pressure ows into the

APPS 160 and exits at a much lower saturation pressure
and temperature Liquid nitrogen enters the APPS 160 unit
through an automatic solenoid valve and exits through a
one-inch vacuum insulated female bayonet A differential
pressure switch maintains the liquid level in the cylinder

The internal pressure of the cylinder is controlled by the
combination of a pressure switch connected to the solenoid
valve and a back-pressure regulator If the pressure exceeds
the set point of the back-pressure regulator, the pressure
switch activates a solenoid valve that rapidly vents the APPS
160 down to the desired working pressure

Technical Features

• Tighter pressure control for the lower pressure liquid
application

• Adjustable outlet pressure ranges

Product Manual

The APPS 160 Product Manual is designed to be used in
conjunction with APPS 160 provided by Chart If there are
any questions regarding the operation of this unit, contact

Chart’s Technical Service division at 1-800-400-4683.

This manual contains information regarding the safe
operation and handling of liquid nitrogen, argon and oxygen
with this unit It should be thoroughly read and understood
by anyone that operates the equipment

The safety requirements for operating the unit and handling
of extremely cold liquid products are shown in the Safety
section Use this safety section as a “Safety Checklist” each
time the equipment is being used

The Installation / Operation section includes information on
how to install the APPS 160, initial start-up and operation of
the unit and references any adjustments that may need to be
made

For information on identication of components, schematic

of the unit, electrical schematic, or service information see

the Specications section.
