Carleton Technologies - manufactures Shuttle atmospheric control system, EMU regulators, temperature control components, Station airlock components




Atmospheric Revitalization and Pressure Control System (ARPCS) Carleton designed and developed the ARPCS for the Space Shuttle Orbiter. It consists of a nitrogen/oxygen control panel, nitrogen/oxygen supply panel, oxygen partial pressure sensors, cabin positive pressure relief valves, cabin negative pressure relief valves, and cabin pressure bleed valves. Complementing the ARPCS are the Airlock Support Components (ASC), which consist of a pressure gage, equalization valve, depressurization valve, oxygen supply valve, and isolation valve. The ARPCS provides: A two-gas atmosphere of nitrogen and oxygen to the crew compartment and habitable payload modules Oxygen to the emergency breathing subsystem and ASC subsystem Nitrogen for pressurization of the potable and waste water tanks Among the products Carleton manufactures for ECLSS are: Atmospheric Revitalization and Pressure Control System Primary Life Support System and Secondary Oxygen Pack Regulators Airlock Nitrogen/Oxygen Components Water Spray Boiler Regulator Radiator Isolation Valve
