Fire suppression FAQ

  • An AFEX fire suppression system is a pre-engineered fire protection system designed primarily
    for heavy equipment and special hazard applications. Systems are manufactured by AFEX Fire
    Suppression Systems and are designed to detect and suppress fires quickly before they spread.

  • The system uses linear detection wire or sensors to identify heat or flame. When a fire is
    detected, the system automatically releases a suppression agent through strategically placed
    nozzles to extinguish the fire.

  • AFEX systems commonly use dry chemical agents (such as ABC powder) or clean agents
    depending on the application.

  • AFEX systems are commonly installed on:

    • Construction equipment (excavators, loaders, dozers)
    • Mining equipment
    • Forestry machinery
    • Waste and recycling equipment
    • Agricultural machinery
    • Buses and specialty vehicles

  • Yes. AFEX specializes in mobile equipment fire protection, particularly in harsh and high-risk
    environments.

  • Yes. They can be configured for generators, hydraulic power units, industrial machinery, and
    other fixed applications.

  • AFEX systems are typically automatic but also include manual activation options inside and
    outside the equipment.

  • Most systems use linear detection tubing that bursts at a specific temperature, triggering agent
    discharge. Some systems may use electrical detection components.

  • Many installations include optional engine shutdown and fuel isolation features to help prevent
    fire re-ignition.

  • Yes. AFEX systems are commonly retrofitted onto existing fleets.

  • Inspection frequency varies, but typically:

    • Daily visual inspections
    • Semi-annual professional inspection and maintenance

    Always follow manufacturer and local regulatory requirements.

  • Maintenance may include:

    • Checking cylinder pressure
    • Inspecting hoses and nozzles
    • Verifying detection tubing condition
    • Testing electrical connections

  • The system must be cleaned, inspected, recharged, and reset by a certified technician before
    returning to service.

  • •Reduced equipment loss
    • Improved operator safety
    • Lower downtime
    • Potential insurance savings
    • Compliance with site or contract requirements

  • Many AFEX systems meet or are designed to comply with recognized standards such as:

    • NFPA guidelines
    • UL listings (model-dependent)
    • FM 5970 HDME Certified

    Certification depends on the specific system and application.

  • In many industries (mining, waste, forestry), insurers or site operators require approved fire
    suppression systems.

  • Systems are designed for extreme environments, including high heat and cold climates,
    depending on the configuration.

  • Dry chemical agents can require cleanup but are effective at rapidly suppressing fire. Clean
    agent systems are available for sensitive equipment.

  • Activation is typically immediate upon detection, allowing rapid fire knockdown.

  • Discharge duration depends on system size and configuration but is engineered to effectively
    suppress targeted hazards.

  • Cost depends on:

    • Equipment size
    • Number of hazard zones
    • Agent type
    • Installation complexity

  • ROI is often realized through:

    • Prevention of catastrophic equipment loss
    • Reduced downtime
    • Insurance savings
    • Enhanced safety compliance

  • Yes. Warranty coverage varies by product and region.

Auto-Lube FAQ

  • Yes, Graco has covered all types of Auto lube systems including series progressive, single line, twin line.

  • Reduce time on site, increased pin & bearing longevity, higher machine resale value, less grease
    consumption, no line boring.

  • ROI often occurs within 6–18 months due to reduced downtime and maintenance costs.

  • There are many variables when designing lubrication systems which depict costs. Our smallest automatic
    system starts at $2630 CAD for a 1 Liter Pump w/8 Grease points.

  • Many systems include visual indicators, pressure sensors/gauges, alarms, or controller diagnostics.
    Forcing the system to cycle during machine maintenance is recommended. There are many
    troubleshooting steps to consider based on the type of system.

  • Yes. Systems can be installed on new or existing machinery.

  • Frequency depends on system settings and equipment requirements. Many systems operate in timed
    intervals or based on machine cycles.

  • Routine inspection is recommended monthly or per manufacturer guidelines. Reservoir refilling
    depends on usage & environmental conditions.

  • Some systems detect pressure increases and trigger alarms. In a case where cycle indicators are not
    installed, the lubricant may be relieved to atmosphere which should be spotted on a circle check. Series
    Progressive systems can stop cycling if one outlet is blocked & when properly installed will alarm the
    operator to shut down. Single or dual line systems cannot alert the operator that a line is blocked.

  • Yes - However when properly configured, it delivers precise metered amounts, preventing over- or under-
    lubrication.

  • Most systems use grease (NLGI 000 to 2, depending on the design) or oil (various viscosities depending
    on application).

  • Based on bearing type, size, speed, load, and manufacturer recommendations.

  • Depends on lubricant and system design. Specialized systems are available for extreme cold or high-
    temperature environments in the range of -40C to 60C

  • Yes. They reduce lubricant waste and prevent excess grease discharge into the environment.

  • Yes. Warranty on parts is held by the manufacturer & we guarantee our installs for 1 year.

  • Common types include:

    • Single-line parallel systems
    • Dual-line systems
    • Progressive systems
    • Multi-line systems
    • Oil circulation systems
    • Oil and air systems

  • Some systems attempt to lubricate even after the pump is empty forcing air in the lines. Single & Dual
    line systems may not be able to force the air out of the mainline which results in alarm condition. Series
    progressive will force out the air out & is typically less troublesome when air is in the lines.

  • If the pump is made for it, yes. Outdoor applications will see temperature changes throughout the year. It
    is recommended to make your changes at the start of the season and maintain the same lubricant until
    the next season. Change when the reservoir is empty.

  • Mixing of lubricants and/or water intrusion.

  • Often the pins, bushings or weldments need to be modified to accept a feed line. We suggest no welding
    or drilling in high stress areas. Rather the pin or bushing be modified to accept the line in a better
    location. This increases the price of an installation, yet it is properly installed to reduce line damage
    ultimately saving the pin joint.
