AVOID BATTERY CASE EXPLOSIONSMINIMIZE THE RISKS:

WITH OUR PATENTEDBENZING VENTS.

Li- ion cells can thermally overheat due to a

wide number of reasons and then eventually

exceed a critical temperature of up to 195 °C

/ 380 °F which leads to an unstoppable chain

reaction (thermal runaway).

The resultant volume of gas of several hundred

l / s could cause the casing to explode. Thanks

to the BENZING VENTS - range it is possible to

reduce the chances of an explosion in the case

of a thermal runaway.

Our patented and high-performance protective

elements safely channel off the toxic gases both

indoors and outdoors. The choice of materials

has been adapted to harsh operating conditions

and BENZING VENTS products comply with

automotive test guidelines.

New products undergo in-house tests, even in

the development phase, while the experience

that we have gathered from many automobile

projects has helped us a lot. As well as this we

take care to ensure that the valves sit securely

in the casing in the case of high gas pressure,

such as during a thermal runaway.

We can also work out custom solutions with

you to bring your ideas to fruition.

PTFE membranes can also be added to

our bursting discs, allowing the pressure

compensation to release pressure from the

casing seal.

Our products have the

following features:

Simple, captive and shear-proof fitting;

can be fitted without instructions

Can be placed in any conceivable

position – even horizontally

Non-flammable (UL 94 / V0)

Can be individually adapted for

air flow rate and water retentivity

Outstanding value for money

Continuous gas permeation for

pressure equalisation

High chemical and temperature resistance

for adverse environmental conditions

Reliable protection of the

casing from liquids

Retention of low-viscosity oils

Dustproof as per IP3 to IP6KX

Waterproof as per IPX7

Pressure-washer-proof as per IP9k

Stone-chip -resistant

Maintenance-free (as long as not triggered)

Can be recycled and contains no

dangerous substances

Can withstand humidity of up to 90 %

(not condensed)

Safely drains gas out

when used inside
