Shelf
Latest Esco Technologies (Asia) Pte Ltd Patents:
The main objective of the shelf is to allow both small and heavy loads to be placed on both sides of the shelf without influence on airflow inside the testing equipment. It includes a shelf with an obdurate steel wire frame and a stainless steel plate with holes. The holes promote free air flow inside the testing equipment. The shelf has a parallel runner so that it will not be dumped when the user pulls or pushes the shelf for adjusting the experimental loads.
