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 jet-wash downs. Our most recent development is the world’s first 3-A approved hygienic interlock – the HGL.
It is critical to prevent contamination and bacterial growth where safeguarding solutions sit in near proximity to food, beverage, and pharmaceutical manufacture.
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 offers an open, stainless-steel & easy-to-clean design with an 8,000N retention force to prevent unsafe access. 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.
Louis represents a range of interlocking solutions in addition to the HGL, designed for the harshest cleaning and wash down applications. All products within the Louis range are designed with the highest level of ingress protection IP69 and third party tested and approved.
