Designed to save energy and create better working conditions where fast access is required.
Dortek’s range of high-speed doors are eco-efficient high-speed internal and external doors designed to prevent cross-contamination, save energy consumption and reduce the sound of noisy plant and guard machinery.
Our durable exterior doors are designed to cope with heavy usage and demanding weather conditions, while their fast operation improves productivity and helps lower energy costs by reducing the impact of pressure and temperature changes.
Hygienic Transfer Hatches and Trolley Hatches
Pass through hatches are often vital to a cleanroom’s efficient operation, whether it is raw materials in, finished product or packed items out or the throughput as part of the manufacturing process.
Hygienic transfer hatches/trolley hatches and are designed to provide a safe and easy way to transfer products or materials between clean rooms and adjacent non-sterile areas.
Dortek’s range of hygienic transfer hatches has either electromagnetic or mechanically interlocked doors to prevent depressurisation and minimise the risk of contamination.
The doors are deliberately not sealed in order to allow a small volume of air from the clean side (which is normally at higher pressure) to continuously flush the interior of the hatch. This volume is so small by comparison with room air flows, that it will have no perceptible effect on room pressures.
Dortek offers a wide range of standard-sized, custom made and lead-lined hygienic transfer hatches.
