Chalco Eleven designs, manufactures and supplies Communication Systems for Air Diving, Saturation Diving, Medical, Underwater, Topside, Vessel, Platform, Shore side, O2 Treatment Centres, Hospitals, and Diving Chamber Complex. Whether it is Dive Control communicating with the Bell, Sat Control communicating with Chamber Complex, or whether it is an Air Dive Spread to Topside, Chalco can supply Comms or Switching Units to cater for atmospheric or helium speech. Chalco Eleven are the leaders in Diver Communication and Development. Twenty years ago we created Modified Rhyme Test (MRT) for evaluating intelligibility of helium speech. Chalco recorded the Divers' speech on a digital audio tape (DAT) in the Chamber from atmospheric to 450MSW. Chalco offers a service whereby we evaluate, fault find, rectify and improve intelligibility in your Diving Complex. We design and build various noise inhalation units.
