Overview
Fortress have worked closely with the Food and Beverage industry for decades, providing the most robust stainless steel safeguarding solutions to withstand harsh cleaning and wash down. Our most recent development is the world’s first 3-A approved hygienic interlock – the Hygienic Guard Lock (HGL).
Where safeguarding solutions sit in proximity of food, beverage, and pharmaceutical manufacture, preventing contamination and bacterial growth is critical. The quest to find a manufacturer of a safeguarding solutions which can enforce run down times to keep operators safe from hazards, withstand the gruelling clean in place procedures, whilst designed to prevent contaminant growth, is over.
The HGL features an open, stainless-steel & easy-to-clean design with an 8,000N retention force. FDA approved PBT rubber seals and no metal-on-metal contact guarantee maximum protection against water and foreign body ingress during clean in place procedures.
HGL is an addition to the Louis range of interlocking solutions, designed for the harshest cleaning and washdown applications. All products within the Louis range are designed with the highest level of ingress protection IP69 and are third party tested and approved.
