This design provides a dedicated and fixed position for the optional Low-Level and Temperature Alarm LLTA. The LLTA continues to monitor the freezer’s temperature and level while product is removed or inserted, providing product security. An Autofill system will be available for the larger models. We custom designed our one-piece lid to enable the operator to remove the lid, securely position it on one of the handles, and have both hands free to quickly access samples. Our premium multi-layer insulation and other materials, together with the latest vacuum technology systems provides the leading industry performance. Engineering utilized finite element analysis, with specific testing to create durable aluminum freezers suitable for today’s requirements.
