Innovation Exchange Challenge: Condensation Removal

NSTIx seeks a portable discreet way to either prevent or significantly reduce the formation of condensation caused by working in confined spaces.

Opportunity Details

Successful applicants will be given the opportunity to pitch their solution to Op-Tech Co-Creation team members, and may have the opportunity to work in collaboration with the NSTIx Operational technologies co-creation centre. A follow-on project may be funded. It is anticipated that, depending on the final design, unit cost and performance, up to a few hundred units will be required by government teams.

Several UK Government bodies, notably, those working in the field of law enforcement, have a requirement to operate discreetly from unventilated, confined spaces. A typical scenario would be police officers in a parked car undertaking surveillance of suspected criminal activity. Such scenarios take place all year round. When the weather is particularly cold, humid or hot, problems can arise from excessive condensation in the work area. This is exacerbated in high-stress situations, where officers may be perspiring or breathing more heavily than normal. It’s often undesirable to open doors or windows, and in the case of discreet vehicle-based work, it’s not feasible to drain the battery through use of the vehicle’s own ventilation system, or to mitigate this by leaving the engine running to maintain a good state of battery charge.

There is a range of commercial and domestic active and passive portable dehumidifiers that could help to remove excessive moisture from the air and alleviate the problem of condensation forming on windows and within sensitive electronic equipment in confined spaces. Active dehumidifiers, however, invariably require a mains electricity supply to operate which, in many scenarios, would not be available. Passive, desiccant-type dehumidifiers have the advantage of not requiring power, but they’re unable to absorb moisture at a sufficient rate to provide an effective solution to this challenge.

The gap, therefore, is for a portable, either self-powered or unpowered, and discreet (quiet) in operation means to either prevent or significantly reduce the formation of condensation on windows and other surfaces caused by people working in confined spaces.

Briefing Call
