Key Features

ISO Class 7

ISO Class 7 compliance over the full duration of the depyrogenation cycle, tested and documented before delivery of every oven.

Temperature Uniformity

Uniform temperature throughout the chamber without adjustment. No temperature ramping required during the heating and cooling phases, significantly reducing cycle duration.

Reliable Performance

High quality stainless steel construction with fully welded chambers–no screws or rivets–and industrial-grade PLC control systems, ensures reliable performance while reducing downtime and maintenance costs.

Warranty

Backed by a standard 24-month warranty to ensure prompt, dependable service and lasting peace of mind.

Operation Overview

BMT USA depyrogenation ovens feature a unique chamber construction and filter suspension system that work together to achieve ISO Class 7, while allowing for full speed heating and cooling without the risk of generating particles.

Automatic Depyrogenation Cycles

Our depyrogenation cycles are fully automatic and optimized for improved energy savings without compromising performance, ensuring the complete destruction of pyrogens from pharmaceutical packaging and equipment.

1. Heating & Drying

  • The cycle starts with the drying phase. During this phase, the damper on the exhaust is open to ensure all moisture is removed from the chamber.
  • Each oven is equipped with a powerful heating element to reduce heating time. Due to specialized filtration suspension system, ramping is not required during the heating and cooling phases, reducing the cycle time while maintaining ISO Class 5 conditions.

2. Sterilizing

  • After the drying phase completes, the damper will close and the temperature will quickly rise to the sterilizing temperature. The damper remains closed during the entire sterilization phase.
  • The sterilizing timer can be started either by delay timer or load sensors. If load sensors are chosen, the sterilizing timer will only run if all load sensors are within an acceptable range from the sterilizing setpoint.

3. Cooling

  • Forced air cooling or water cooling is available to deliver rapid cooling for applications that require reduced cycle durations.

Accessories

We offer a range of customizable accessories, including transfer trolleys, mobile racks, wire trays and cassettes:

Transfer Trolleys

The transfer trolley allows for transporting the mobile rack outside the chamber. The transfer trolley is locked to the chamber during loading to ease operation.

Mobile Racks

The mobile rack is available with fixed or removable tray supports. The height between the tray supports can be adjusted to suit customer load configurations. Additionally, the mobile rack is equipped with a smooth running wheel that can also withstand temperatures as high as 300 °C, without requiring lubricant.

Cassettes

The Cassettes can also be customized and are available in a perforated design. All mobile rack wire trays and cassettes are constructed with AISI 316L stainless steel.
