ADJUSTABLE PRESSURE PHASE SEPARATOR The Adjustable Pressure Phase Separator (APPS 160) unit is used to lower the saturation point of liquid nitrogen, when supplied from a high pressure bulk storage tank. Liquid nitrogen saturated at a high pressure flows 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 oneinch vacuum insulated female bayonet. A control panel maintains the liquid level in the cylinder. An adjustable back pressure regulator is used to maintain tank pressure. During times of rapid pressure increases, such as a fill, a vent solenoid valve will open to rapidly vent the APPS 160 unit down to the desired pressure. The APPS 160 is designed to be effective when placed directly next to the bulk tank supply. If planning to use the APPS away from the bulk tank, you must first consult a Chart engineer and have written approval of the design. APPS-Tel digital control panel has replaced the Gen 3 analog control box Generation 4 Benefits • More stable digital control averages the liquid level • More robust measurement of differential pressure • Added safety circuit monitors muffler temperature. If liquid is sensed, a visual and audible alarm is enabled and a supervisory microprocessor shuts down the inlet valve. • APPS-Tel Liquid Level Gauge - Standard on Gen 4 APPS Unit - Improved level accuracy - Telemetry option to remotely monitor tank level (low/high alarm) - LCD display of pressure and liquid level in English or Metric units - Simplified calibration - Internet option capable of sending email or text alert based on low/high level alarm Technical Features • Allows low pressure liquid and high pressure gas from a single storage vessel • More precise pressure control on liquid use • Mini-bulk storage for under-sized vacuum insulated pipe lines • Low cost alternative to two bulk tanks • Two operating pressure ranges available for pressure adjustments from 10 − 85 psig • Stain
