We arrange Door-to-Door Delivery through our carefully chosen 3rd party transport partners.  Like you, we demand our partners supply quality service …whether large industrial or smaller commercial businesses – we will do our best to supply the best quality and value solutions.

The vent positions in each of our cabinets have a bung to seal and prevent any fumes from leaking from the cabinet.  This is to prevent fumes from leaking into the room, that the cabinet is located in.  Should these fumes ignite the flames could track back into the cabinet where an explosion may occur.     Ninety five percent of General Flammable and Chemical goods do not require the cabinet to have any ventilation.   All of our Cabinets have provisions for air flow through the air cavity between the (1.2mm thick steel) double skins of the cabinet.

There is a 2” (50mm) bung in each side of the cabinet (one at approximately 250mm up from the bottom on the left side and one approximately 250mm down from the top on the right hand side).   This allows you to screw in a 2” inlet pipe to introduce air into the cabinet cavity (from outside) and through the spark arrestor (gauze) into the cabinet and exhaust the air outside through the opposite side with a similar 2” pipe attached to the other side of the cabinet.    You can attach an inline fan to assist air flow if required although you may require the assistance of a Compliance Certifier to ensure the system complies with AS1940-2017.

Our cabinets are all steel and are made from heavy 1.2mm thick metal including the double skinned roof, walls, doors and bunded floor.

You are buying direct from the manufacturer, there are no middle men, in some cases we can be $1000 less than other retailers and our cabinets are definitely superior!

We design them, we make them , we warranty them – our credibility is through our thousands of customers

All our cabinets are fully seam welded for strength in case of an internal explosion.

All our cabinets are powder coated using a polyester exterior powder.   Interior powder is for light fittings etc and is cheaper.

Our outdoor cabinets are powder coated with the TSCW powder coat system

All our double door cabinets have sequential self closing doors. See below.

Our company, founded by Bruce in 2002, has evolved into a trusted provider of superior-quality cabinets.  You can have peace of mind knowing you have purchased the right cabinet.

Li-ion Battery Charging
Where would be the optimum location for a lithium-ion cabinet ?

These are designed for indoors, closer to a door or open window as the 5 fans draw in clean air and forces it over and around the charging batteries to keep the batteries cool at around 10-25 degrees C regardless of the outside temperature.   Also, when a battery explodes large amounts of Hydrogen Fluoride smoke maybe omitted so this is best to be exhausted in a ventilated area.

We have supplied these cabinets  to many extreme temperature locations in Western Australia where temperatures can exceed 50 deg C with no problems. Therefore this ambient heat does not appear to be much of a problem .

Do not open the doors if you see smoke omitting – you can’t do anything.  Water will only produce more toxic hydrogen fluoride smoke and will not extinguish the battery fire.  The battery fire is fuelled only by its own energy not solvent, oils or any other substance.  Therefore,  it must be allowed to spend that energy and be confined within its compartment while it is happening.

No.  We tested that option and one time the device did not deploy.   The explosion was too quick for the extinguisher and burnt it out before the extinguisher was deployed.  The other problem was if the extinguisher did deploy but the fire was in the bottom compartment, there could possibly be 19 additional batteries, chargers and shelves in the way before the suppressant could even get near the burning battery.   It also mounted false hope that the batteries would be saved from explosion should there be one fitted.

After much research we elected to create compartments with the adjustable shelves with 1260 Degree C (used in our standard cabinets, and 1430 Degree C in our heavy duty cabinets) continuous rated HotWall insulation within the shelves walls and doors to mitigate the possibility of exploding batteries lighting up other batteries in an upper or lower compartment .  The shelves, while adjustable and removable, have very little clearance gaps which also enhances the compartments air tightness.  Apart from the fan within each compartment, exhausting the cooling air over the batteries,  the vent plays an important role when the battery explodes.  The hydrogen gases first exhaust through the spark arrestor at the start of the vent within the cabinet before being followed by the toxic gases such as hydrogen fluoride, carbon monoxide, carbon dioxide and many more.  Without these vents the gases released from the exploding battery could build up so much pressure within the cabinet that they could cause the doors to blow open.  Hence, storing batteries just in a flammable goods cabinet could be very dangerous.

 

The problem being that some batteries take a lot longer to charge than others eg, one battery may be 10% charged and another maybe 90% charged.  How will you know which one will require what length of time to charge.   All battery chargers have their own built in device to turn off the charger once the battery is fully charged.   If the charger is faulty then the 2 pole breaker will sense an earth leak and trip – or it can trip if it is over loaded.

Thermal runaway is one of the primary risks related to Li-ion batteries, where the battery cell enters an uncontrolled, self-heating state. Thermal runaway can result in violent cell venting, vapour releasing and fire.

A battery in thermal runaway, where the contents of the battery are the fuel for a fire, is different to a fire fuelled by combustible material such as wood. Once the battery has ignited, it continuously releases energy as heat. A Li-ion battery fire can be extinguished, but reignition through the chemical reaction can occur without warning.

In short, no we dont. Fire suppression devices can provide the belief that with their presence, there would be no fire or explosion (of the batteries) inside the cabinet.  However what we found, is that they do not deploy every time a fire is detected within the cabinet. If it fails to deploy, and you’re relying on it to contain an explosion, the consequences could be severe. 
 
In 2021, we designed our Lithium Charging Cabinets with compartments resembling small kilns, specifically to contain explosions and extreme heat from failing batteries. We ensured there is no venting through the shelves that could allow flames or heat to spread between compartments, potentially igniting other batteries. This could lead to a catastrophic fire. To prevent this, we incorporated our high-performance 1260°C continuous-rated HotWall insulation into the shelves, walls, doors, and other components. This design ensures that if a battery experiences thermal runaway and explodes, the explosion is contained until the energy is dissipated. Additionally, cooling fans help regulate the temperature of the batteries during the charging process, keeping them cooler and reducing the risk of overheating.
