Work Experience
Plumis
2017
Plumis is a Queens award winning, technology startup in London. The Plumis system can be discretely retrofitted into buildings and can locate fire using an Infra-red camera. A mist sprinkler can be targeted locally to the fire, ensuring fast suppression and limited water damage.

​
Plumis system was challenging electro-mechanical design. It requires robust mechanical design with electric motor automation, fluid pressure control and remote sensing.
​
The plumis head can be mounted into internal domestic partition wall. The drive system and fluid tank can be stored in the partition cavity or in a external case
In normal conditions the plumis head sits elegantly flush to the wall.
When smoke is detected by the external ceiling mounted smoke detector, the head rotates and searches for the location of the fire using the IR sensor. If located then a water jet is applied using the high pressure pump. For security, the water tank is independent of the domestic supply.

Since water is piped through the axle of the head, the rotation of the head itself can cleverly be used to actuate the water vavle.
The Plumis Automist components are produced using a number of medium volume manufacturing methods in the UK and Far East.
​
Mounts and seals are injection moulded using rigid polymer and elastomers.
​
The high pressure components are machined in stainless steel.
​
The enclosures and brackets are produced from punched and folded sheet metal with powder coating
The Component manfacture and drawing management was carried out in careful alignment with the small in house assembly line in South London.
