APS Steam Sterilizer Horizontal Cylindrical

The APS Steam Sterilizer Horizontal Cylindrical is a heavy-duty horizontal autoclave designed for bulk sterilization applications in hospitals, laboratories, and other facilities where reliable steam sterilization and dryness of sterilized loads are important. The cylindrical, triple-walled construction combines an SS 304 inner chamber, jacket, boiler and outer jacket cover with a sturdy mild-steel support stand.

The sterilizer uses a separate steam boiler positioned below the main chamber, along with pressure control, low-water protection, vacuum breaking and automatic cycle timing features. Standard and customized models can be manufactured according to customer requirements.

Triple-Walled Horizontal Construction

The APS horizontal steam sterilizer features a cylindrical triple-walled design mounted on a sturdy heavy-duty mild-steel square stand.

The supplied construction specification includes:

• Inner chamber — SS 304
• Door lid — SS 304
• Jacket — SS 304
• Boiler — SS 304
• Outer jacket cover — SS 304

The space between the jacket and outer cover is insulated using high-grade fiber/mineral glass wool to help reduce heat loss.

Separate Steam Boiler

Steam is generated in a separate boiler positioned below the main sterilization chamber. This arrangement is designed for steam generation and delivery to the chamber during sterilization cycles.

The supplied specification does not state the boiler capacity or heater wattage.

Pressure Locking & Door Safety

A pressure locking system is provided to prevent the door from being opened while steam remains inside the chamber.

Depending on configuration, the sterilizer can be supplied with a single or double hinged door. The manual radial locking system is made from mild steel with a nickel-coated finish.

The system also includes a spring-loaded safety valve and steam-release valve.

Automatic Pressure & Low-Water Protection

The sterilizer incorporates multiple safety provisions:

Automatic Pressure Control

An automatic pressure control switch monitors jacket pressure. According to the supplied specification, when jacket steam pressure reaches 18–20 psi, the electrical supply to the heater is automatically cut off.

Low-Water Cut-Off

An automatic low-water-level cut-off device is provided to protect the heating element when the water level becomes insufficient.

Automatic Vacuum Breaker

An automatic vacuum breaker is included to break vacuum formation that may occur because of steam condensation.

Digital PID Temperature Controller

The sterilizer is equipped with a digital PID temperature indicator/controller with an LED display.

The controller displays:

• Set value
• Process value

An integrated digital minute timer automatically starts when the selected/desired temperature is reached.

At the completion of the programmed time:

• Heaters switch off automatically
• A cycle-end alarm is activated

This provides automatic timing and termination of the heating cycle according to the programmed settings.

Four-Position Multiport Valve

A manually operated four-position multiport valve is provided for controlling different steam functions, including:

• Steam injection into the chamber
• Dry sterilization
• Steam exhaust

The exact valve operating sequence should be confirmed with the supplied operating manual for the selected configuration.

Silicone Door Gasket

A high-tensile, jointless silicone gasket is used to provide sealing between the chamber and door.

The gasket is seated inside an integrated groove to support proper sealing and minimize steam leakage during operation.

Stainless-Steel Baffle Plate

An SS baffle plate is incorporated for steam distribution. It is intended to help distribute steam effectively and prevent direct steam impact on the sterilized load.
