The Senseair sales office in the USA was contacted by a company working with air conditioning units. Another branch of that company has been a Senseair customer for a long period of time as an OEM producer using carbon dioxide sensors.
In order to develop more environmental friendly air conditioning units, the refrigerant gas had to be replaced with one that is mildly flammable. In order to eliminate the risk of fire caused by leaking gas a safety gas detector is preferred.
A project team was set up at Senseair and two of our technical experts met the customer together with the sales team in USA. The spectroscopic behavior of the gas and possible cross sensitivities was investigated by the research team. A design based on the low-cost module S8 with a custom designed filter was proposed for the specified application. Optical filters and calibration gas was ordered and prototypes were built.
Within six months from project start a set of prototypes had been shipped to the customer for evaluation in their research lab. The prototype development was fully financed by Senseair since we have a long business relation with this customer, know them well and find a strategic value in this business segment.
