Transfer Hatches/Pass Through Hatches

A collage of transfer hatches.

Pass through hatches, also known as transfer hatches, play a pivotal role in ensuring the seamless transfer of materials. Whether it’s transporting raw materials in, dispatching finished products, or facilitating the manufacturing process, these unassuming pass thru hatches are the unsung heroes of cleanroom efficiency. Their robust and durable construction ensures long-term reliability in even the most demanding environments. Moreover, they are designed to accommodate a wide range of operational requirements, making them indispensable in various industries including pharmaceuticals, biotechnology, and electronics.

The primary objective of pass thru’s is to mitigate cross-contamination during material transfer, thus upholding the cleanliness of controlled areas. Dortek, a leading provider of innovative solutions, offers a range of pass through hatches equipped with either electromagnetic or mechanically interlocked doors. These advanced door mechanisms serve a dual purpose: preventing depressurisation and minimising the risk of contamination. In addition to their high functionality, these door systems are designed to be user-friendly, reducing the risk of operational errors and enhancing the overall safety protocols within cleanrooms.

What sets Dortek’s pass through hatches apart is their deliberate design. Unlike conventional sealed doors, these hatches allow a controlled flow of air from the clean side, typically maintained at a higher pressure. This constant influx of clean air effectively flushes the interior of the hatch. Importantly, the volume of air involved is so minuscule in comparison to the room’s airflows that it remains imperceptible, leaving room pressures unaffected. This careful balance helps to ensure that even the most stringent cleanroom standards are met without compromise. Additionally, the materials used in the construction of these hatches are selected for their resistance to corrosion and ease of sterilisation. The hatches have minimal visible fixings, flush designs, and excellent scratch and wear resistance.

Pass throughs silently ensure that materials move seamlessly, while cross-contamination remains a distant concern. Dortek’s innovative range of pass through hatches help improve the efficiency and reliability of cleanroom operations. These hatches are also designed with user convenience in mind, featuring easy-to-clean surfaces and straightforward maintenance procedures. Their sleek, modern design not only contributes to the aesthetic appeal of the cleanroom but also integrates seamlessly with other cleanroom infrastructure.
