Steris Amsco 3052 Washer Safety Features

  • Vertical chamber doors are equipped with an obstruction sensor to detect any door obstruction. If an obstruction is present the door automatically opens.
  • The washer/disinfector is equipped with a safety lockout feature so a cycle cannot start unless the door is fully closed.
  • Door interlock feature is provided to prevent cross-contamination. The door interlock feature allows only one door to be opened at a time whenever power is on.
  • Safety stop pushbuttons, one on the load and one on the unload side, automatically stop all unit operation when pressed.
  • Building electrical supply disconnect switch must be used to shut off power to the unit before servicing.
  • The washer has an Audible Warning System

Wash Chamber Construction

  • 16-gauge, #3-4 L stainless steel, argon-welded and polished.
  • Chamber is of sanitary-type design (horizontal fixed surfaces are sloped, overlapping metal sheets) for complete drain ability and to reduce hard-to-clean locations.
  • Single-walled, insulated construction of the chamber exterior reduces heat loss and noise level to the work area.
  • Rotary spray assemblies are positioned at the top and the bottom of the chamber, each measuring 24-3/8″ (62 cm) long to reach all load surfaces, Spray assemblies are easily removable without tools to aid in cleaning and maintenance.
  • 3-W LED light mounted within an explosion/vapor-proof enclosure, illuminates chamber interior.

System Drying

  • The drying system is a manifold and circulates HEPA-filtered air through piping, accessories, and chamber for 1 to 60 minutes at low temperatures of 108°F (82°C) or 1 to 30 minutes at a high temperature of 240°F (115°C).
  • The system includes a cold water condenser.
  • The system includes a 3hp (2.2 kW), blower and three electric heaters totaling 11.4kW.
  • The system heats and maintains chamber to 180-240°F (82-115°C). No additional ductwork is required.

Pure Water Rinse Supply

  • Washer/disinfector is equipped with Pure Water Stainless-Steel Supply Valve.
  • Pure water from the facility is sprayed over the load under pump pressure for 15 seconds (adjustable from 15 seconds to 15 minutes.).
  • Up to four Pure Water Rinse treatments can be selected per cycle with recirculated water.
  • Pure water can be used for thermal disinfection stage and is heated to 194°F (90°C) using either steam or electric heaters.

Drain Discharge Cool Down

  • This feature assures water drained at the end of each phase, from the chamber sump to the building drain system, does not exceed 140°F (60°C).
  • If the water temperature in the sump is higher than 140°F (60°C), cold water is automatically added to reduce the temperature of the water discharged into the building drain system.


  • Constructed of #304 L Stainless steel with 9.5 gals. (36 L) capacity.
  • Removable stainless-steel filter in chamber sump prevents debris from entering the pump and piping system.
  • The heating coil at the bottom of the wash chamber (sump) raises and maintains water temperature up to 180°F (82°C) during the Wash phase and up to 194°F (90°C) during the Thermal Rise phase.

Chemical Injection Pumps

  • Pumps are optimized to use Prolystica Ultra Concentrate chemicals. Each ultra concentrated product is 10 times more concentrated than an equivalent traditional product; so 10 times less chemical is injected per cycle.
  • The washer/disinfector comes with one enzyme and one detergent injection peristaltic pump which automatically add a selected quantity of chemical from 1/40 to 2oz/gal (0.2 to 16 mL/L)
  • One injection peristaltic pump is dedicated to automatically add a selected quantity of lubricant during the Thermal Rise phase.
  • Pumps are positioned near chemical containers.

Microprocessor Control System

  • Equipped with a 5.7″ (14.5 cm) touch-screen customer interface that is mounted at eye level beside the chamber door on both sides of the unit.
  • Locking program cycle parameters with an access code.
  • Service mode for preventive maintenance testing and facilitate troubleshooting.
  • Built-in service diagnostic program to permit system calibration and verification of component operations.
  • Security lock-out feature that enables programs and temperatures to be locked and unchangeable without the proper access code.
  • Equipped with an audible warning system.
