A client came to DMF wanting a solution for their two warehouses located in Sydney and Brisbane. Being a pet products distributor, a problem was being encountered with the ingress of birds causing spoiling of their pet food products. The solution by DMF, was to install high speed roll doors to the busiest doorways, that would work to minimise the time the openings were left open, and therefore decreasing the chance for birds to enter. Obviously this was not the only solution, and other measures were put into place to achieve minimal entry. Being large door openings, the doors had to provide a good wind capacity, and given that the warehouses were not air conditioned, had to still allow some airflow entry for the comfort of the employees. DMF can provide ventilated panel sections to this rapid doors, and these were located high in the panel design to allow the airflow, and yet prevent the ingress of dust during windy periods.The doors operate automatically by forklifts travelling over the induction floor loops, with self closing after a programmed short period of 10 seconds. Full safety sensors were applied, and additional brush sealing was fitted to the roller head to create a tight seal around the doorway, tight enough to even prevent insect entry. Custom made in our Sydney factory, the Series RL3000 model is a versatile rapid roll door suitable for large range of applications including warehousing and logistics, production and processing areas, security, cleanrooms etc. Contact DMF for more information.
