Reliable fire detection for food manufacturing plants

When food is produced for human consumption, the highest grade of hygiene is required. Food handling areas are regularly washed using steam, heat, pressurised water and/or chemicals, and there may be a requirement for any equipment in the room to be ‘food grade’ as well as being able to withstand such treatment. This severely impacts the options for fire detection. The extremely robust SecuriHeat ADW line-type heat detector is an exception to this, as its stainless steel sensing tubes meet hygiene requirements and withstand almost any kind of cleaning process.

SecuriHeat ADW is a unique linear heat detector which uses a sealed metal tube as the sensing element. Available in food-grade stainless steel, it withstands aggressive cleaning and is also highly sensitive and reliable.

Causes of fires in food manufacturing facilities

• Equipment or heat source failure
• Presence of flammable gasses, vapours and combustible dusts
• Processes involving oils and fats
• Heat from cooking vessels
• Electrical systems in humid conditions

Challenges for fire detection in food manufacturing facilities

• Requirement for cleanroom grade equipment
• Equipment must withstand harsh cleaning techniques
• Complex production machinery
• Smoke dilution due to high airflow and filtering
• Complex and congested ceiling structures
• Obstructed or difficult access

Key benefits of SecuriHeat ADW in food manufacturing facilities

• Sensing tubes available in food-grade stainless steel
• Sealed system with sensing tubes that resist chemicals, steam and pressure washing
• Multi-level warning allows for a staged response according to fire development
• Fast and highly sensitive reaction to incipient fires and heat development
• Simple handling due to detectors being mounted in easily accessible areas
