With this kind of ability, it can reach fire rapidly and suppress the fire with only a matter of a few seconds. With our safety records for high efficiency performance, PEMALL’s Clean Agent cylinders provides excellent service to its valued customers.
Our cylinders are manufactured and are created by our group of hardworking engineering and production team at our facilities in both European and Asian countries. PEMALL has unfailingly passed all extensive and rigorous testing performed by international safety solution and regulation authorities. With our exceptional records for safety and durability, our cylinders are globally used specially on train stations, hospitals, restaurants and other industrial and private companies.
With PEMALL’s Flow Calculation Software that comes with it, you can do accurate calculations of the system quick and easy. You will have full control over your calculations and can easily see how a change of process data (temperature etc.) will affect the measurement of the flow.


ADVANTAGES
The PEMALL-227TM System is residue-free operating extinguishant HFC-227ea has a high extinguishing effectiveness and environmental compatibility (Global Warming Potential GWP = 3500, Ozone Depletion potential ODP = 0). Further advantages are its high personal safety and the small storage volume.
PEMALL-227TM System is Pressurized with nitrogen on the intended system pressure of 360 psi , or 500 psi in order to assure a complete and effective flooding of a protected room.
PEMALL-227TM System extinguishing system knock downs fire with PEMALL HFC-227ea extinguishant that offers optimal fire protection and is particularly suitable for electrical and electronic risks. The system consists of wide range Stainless Steel cylinders.
When HFC-227ea is exposed to temperatures greater than 1300°F (700°C), the by-product Hydrogen Fluoride (HF) will be formed. PEMALL-227TM System are designed to discharge in 10 seconds or less in order to minimize the amount of HF formed.

Long Service Life











CYLINDER BRACKET
Securely mounts the cylinder to support its load. The cylinder bracket should be mounted on a solid load bearing concrete wall. The cylinder stainless steel bracket is chosen as primary means of support, as they enable the gas cylinders to be held tightly and securely during an event of Clean Agent discharge. It is also installed to protect the cylinder from any obstructive positioning.

LIQUID LEVEL INDICATOR
Liquid Level Indicator determines the amount of liquid level in the clean agent cylinder. Once the liquid level is determined, it can then be converted into pounds (kilograms) of Clean Agent present in the agent storage container.

Note:
The Electrical solenoid can be removed for servicing or testing without loss of agent since the SCHRADER (check valve) will close as The Electrical solenoid is removed.
ELECTRICAL ACTUATION UNIT - LATCHING SOLENOID
Our latching solenoid is designed to meet requirements of NFPA 2001, UL 2166, UL 2127 and FM 5600. It is assembled on top of the top plug adapter of the head valve in order to release the extinguishing medium with an electrical current or manual activation via the local manual control. Activation through a push rod that depresses a Schrader valve thereby venting the pressure from the top of the piston in the cylinder valve, allowing the piston to slide upward to commence the clean agent discharge.

MANUAL ACTUATION UNIT
A manual lever and cam arrangement on the actuator permit actuation of the device on a manual basis, thereby overriding and independent of electric power or pneumatic pressure. A pull pin and seal prevent accidental operation of the manual lever. A swivel nut and O-ring seal on the device provides for attachment and seal at the connection point under part number LMCLA-01.
- Used for manual actuation of cylinder
- Equipped with safety pull-pin to prevent accidental manual discharge of Clean Agent
- Self-venting
- Solid brass construction
- Stainless steel operation lock-pin

Note:
Flexible connectors are used to interconnect the cylinder valve devices. These hoses have a stainless-steel wire braid cover and a Teflon liner, and are fitted at each end with a 1/4 in. swivel flare nut.
PISTON ACTUATOR CONTROL HEAD-SLAVE
The Piston Actuator mounts directly to a Top Plug Adapter of the cylinder valve. It features a pneumatically driven piston that depresses a Schrader Valve, thereby venting the pressure from the top of the piston in the cylinder valve, allowing the piston to open and commence cylinder discharge.
Actuation of the master or prior slave cylinder valve assembly permits pressure to be applied through a flexible connector set connected to the pneumatic actuator, which in turn applies pressure to its operating piston .

Low Pressure Supervisory Switch
The low pressure supervisory switch can detect a drop in pressure. One version of the switch is normally closed (N.C) and the second version is normally open (N.O.). The switch is referenced in the no pressure condition. When the cylinder is pressurized until the actuation pressure is reached, the contact for the normally closed (N.C.) switch will shift from normally closed to normally open status and vice versa for the normally open (N.O.) switch.
