APS Steam Sterilizer Horizontal Rectangular

The APS Steam Sterilizer Horizontal Rectangular is a heavy-duty horizontal autoclave designed for institutional, hospital and laboratory steam sterilization applications. Its rectangular, triple-walled construction provides a smooth, crevice-free chamber with rounded corners, while the SS 304 chamber, jacket, boiler, door lid and outer jacket cover provide a robust stainless-steel construction.

The sterilizer incorporates a separate steam boiler, pressure and vacuum safety systems, digital PID temperature control, automatic timing, condensate management, validation port and manual steam-control functions.

Standard configurations are available with single or double hinged doors, while electrical supply depends on the size of the autoclave.

Rectangular Triple-Walled Construction

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

The supplied construction specification states that the following components are made from SS 304:

• Inner chamber
• Door lid
• Jacket
• Boiler
• Outer jacket cover

The rectangular chamber incorporates smooth, rounded, crevice-free corners, supporting easier cleaning of the chamber surfaces.

Separate Steam Boiler

Steam is generated in a separate boiler located below the main body of the sterilizer.

This configuration separates steam generation from the main sterilization chamber while allowing steam to be introduced into the chamber through the supplied steam-control system.

Pressure-Locking Door

The SS plate door is equipped with a pressure locking system designed to prevent the door from being opened while steam remains inside the chamber.

The sterilizer can be supplied with:

• Single hinged door
• Double hinged door

The door uses a manual radial locking system.

Pressure & Vacuum Safety

Multiple safety mechanisms are incorporated into the sterilizer.

Automatic Pressure Control

An automatic pressure control switch provides over-pressure protection. According to the supplied specification, when steam pressure inside the jacket reaches approximately 18–20 psi, the electrical supply to the heater is automatically cut off.

Automatic Vacuum Breaker

An automatic vacuum breaker is provided to break vacuum that may form as a result of steam condensation.

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.

Pressure Monitoring

The sterilizer includes:

• Jacket pressure gauge
• Chamber compound gauge
• Spring-loaded safety valve
• Separate manual steam-release ball valve for the jacket
• Separate manual steam-release ball valve for the chamber

Digital PID Temperature Control

The sterilizer is equipped with a digital PID temperature indicator and controller.

The LCD displays:

• Set value
• Process value

An integrated digital minute timer automatically starts once the desired/set temperature is achieved.

When the programmed time period ends:

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

This provides automated temperature-based timing and cycle completion.

Steam Distribution

An SS baffle plate is provided to support effective steam distribution and help prevent direct steam impact on the sterilization load.

The chamber condensate line incorporates a steam trap for condensation management and to support the required temperature conditions.

A plug screen is also provided to help prevent line choking caused by sediment discharge.

Door Sealing

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

The gasket sits in an integrated groove to provide the specified sealing arrangement and minimize steam leakage.

Validation Port

A validation port is provided for sterilization validation activities.

The supplied source does not specify the validation instruments or validation protocol, so these should be confirmed according to the selected configuration.

Four-Position Multiport Valve

A manually operated four-position multiport valve is provided for controlling:

1. Steam injection into the chamber
2. Dry sterilization
3. Steam exhaust

The exact operating sequence should be followed according to the manufacturer's operating instructions.

Water-Level Monitoring & Heating

The sterilizer includes a glass water-level indicator for monitoring the water level.

The heaters are designed to be easily replaceable, supporting maintenance of the heating system.

Industrial-grade energy-efficient heaters are specified for the unit.

Electrical Configuration

The electrical supply depends on the size of the autoclave:

• Small-size autoclave: 230V single phase
• Large-size autoclave: 440V three phase

The exact electrical load and heater rating are not provided in the supplied source.
