Clean Agent Fire Extinguisher, Automatic Temperature Detection Type (PZGW Series)
The Automatic Temperature Detection Clean Agent Fire Extinguisher (PZGW Series) is a PAF-222 clean agent fire extinguisher with automatic temperature detection. It utilizes the PAF-222 Clean Agent [FK-5-1-12] and activates when the temperature reaches 68°C. It is ideal for electrical cabinets, MDB cabinets, electrical rooms, server rooms, and spaces requiring automatic fire protection systems. When the ambient temperature rises and exceeds the limit set by the heat-sensing glass bulb, the bulb will burst, automatically triggering the system to instantly discharge the extinguishing agent to reduce the temperature and extinguish the fire.

Who is the PAF-222 Automatic Fire Extinguisher PZGW Model Suitable For?
The PAF-222 automatic fire extinguisher, PZGW model, is suitable for organizations requiring localized fire suppression systems in closed or semi-closed areas. This is especially true for areas containing electrical equipment, electrical cabinets, MDB cabinets, control panels, electrical rooms, server rooms, or areas left unattended at all times.
The PZGW is an automatic clean agent fire extinguisher utilizing PAF-222 / FK-5-1-12 / Perfluorohexanone. It is designed to respond to heat within its installation area, automatically activating when the temperature reaches approximately 68°C. Actual operational details should be referenced from the product model's SDS / Datasheet / Certificate.
User groups suitable for the PZGW include engineers, safety officers, maintenance departments, building managers, factories, warehouses, data centers, server rooms, electrical rooms, and procurement departments looking to enhance fire protection at specific high-risk points.
What Type of Areas is the PZGW Suitable for Installation?
The PZGW automatic fire extinguisher is ideal for areas requiring localized protection, particularly those with electrical equipment and a risk of heat accumulation, short circuits, or continuously operating equipment.
Application Area | Reason why it is suitable |
|---|---|
Electrical Cabinets / MDB Cabinets | These are closed or semi-closed areas with electrical equipment and specific high-risk points. |
Control Panels | Suitable for control panels, machinery, or electrical systems requiring localized protection. |
Electrical Rooms | Used to supplement protection in areas with critical electrical equipment. |
Server Rooms | Suitable for IT equipment areas where minimizing residue is essential. |
Data Centers | Used as part of a localized protection plan, which should be evaluated in conjunction with the primary system. |
Warehouses / Factories | Suitable for control cabinets, machinery, or high-risk areas that are left unattended at all times. |
For large areas or complex systems, a technical team should evaluate whether the PZGW should be used as a localized device or in conjunction with a fixed fire suppression system.
Key Features of the PZGW Automatic Fire Extinguisher
The PZGW is an option for buyers looking for more than a handheld fire extinguisher. It can be installed at high-risk points and operates automatically when specified conditions are met, making it suitable for areas that may not always have personnel nearby.
Key features to consider:
Operating as an automatic fire extinguisher.
Utilizes PAF-222 / FK-5-1-12 / Perfluorohexanone clean fire extinguishing agents.
Suitable for electrical cabinets, MDB cabinets, control panels, and electrical equipment areas.
Helps minimize residue compared to dry chemical powder extinguishers.
Suitable for closed or semi-closed areas requiring localized protection.
Operates automatically when the temperature reaches approximately 68°C, subject to SDS / Datasheet / Certificate references.
Can be used to supplement fire protection plans in factories, buildings, data centers, and electrical system areas.
Why Automatic Systems are Suitable for Electrical Cabinets and Unattended Areas
Electrical cabinets, MDB cabinets, and control panels are areas prone to heat accumulation or short circuits. Often, these high-risk points do not have personnel nearby at all times. If an incident occurs when no operators are present, responding with a handheld extinguisher may not be timely.
Automatic fire extinguishers like the PZGW are therefore suitable for installation in areas where the system needs to self-respond when temperatures reach a specified level. This adds a layer of localized protection, particularly in hard-to-reach areas, enclosed cabinets, or zones that are not constantly monitored by officers.
However, the PZGW should not be seen as a replacement for a building's entire fire protection system, but rather as part of a safety plan combined with electrical equipment inspections, alarm systems, maintenance, and other preventive measures.
How Does the PZGW Differ from a Handheld Fire Extinguisher?
Handheld fire extinguishers, such as the MJZ model, are suitable for users to pick up and discharge when an incident is detected, but this requires someone to be nearby and able to reach the scene in time.
The PZGW differs in that it is an automatic fire extinguisher, suitable for localized installation in areas where the system needs to self-respond when specified conditions are met, such as when the temperature reaches approximately 68°C.
Type | Application Characteristics | Suitable For |
|---|---|---|
MJZ Handheld | Requires a user to pick up and discharge. | General areas, server rooms, electrical rooms, offices, factories. |
PZGW Automatic | Installed at a fixed point and operates automatically when conditions are met. | Electrical cabinets, MDB cabinets, control panels, high-risk unattended areas. |
Many areas can utilize both types in combination, such as using the PZGW for specific electrical cabinets or high-risk points, and having handheld MJZ extinguishers available for personnel to use in nearby areas.
How to Choose and Use PZGW in Combination with Fire Protection Systems
Selecting the PZGW should begin with an assessment of actual high-risk points, such as electrical cabinet size, type of equipment inside, normal operating temperatures, ventilation, and whether the area is closed or semi-closed.
Basic guidelines:
Use the PZGW at specific high-risk points, such as electrical cabinets, MDB cabinets, or control panels.
Use in combination with handheld fire extinguishers, such as the MJZ, for manual response by personnel.
Use in combination with warning systems, smoke detectors, or temperature monitoring systems if the area is high-risk.
For large Data Centers or Server Rooms, evaluate in conjunction with fixed fire suppression systems.
Verify the SDS / Datasheet / Certificate before actual installation, particularly regarding suitable area coverage, operating temperatures, and product limitations.
