The Dryden Aqua Air Diffuser is a semi-flexible, high-efficiency fine bubble air diffuser available in 9 different lengths, depending on the air through-put required . It provides oxygen transfer rates of up to 5kg/kw, 10m3/h of air and 1 kg of O2/h. Its semi-flexible construction with its own internal ballast will stay on the bottom of tank or pond without the need to be anchored to the floor. The Dryden Aqua Air Diffuser combines excellent performance with cost effectiveness for aeration, oxidation and biological treatment. Dryden Aqua Air Diffuser Key Features Semi-flexible, tubular construction Self weighted Available in 9 lengths from 0.3 – 3m. Air handling capacity from 1 – 10m3/hr Less than 0.2 Bar (3 psi) pressure differential Oxygen transfer efficiency up to 5 kg/kwhr Resistant to calcification Easy to clean and maintain Robust and long-lasting (typical lifespan is 5 – 10 yrs) Built in non-return valve Stainless steel and plastic construction Can be used with Air, N2, CO2 Oxygen Transfer Performance Surface aerators waste a huge amount of kinetic energy throwing the water into the air, transfer coefficient is 1 kg to 2 kg of oxygen per kW. Membrane diffusers are more efficient at 2 kg to 3 kg of oxygen per kW. The Dryden Aqua diffuser at over 5 kg is therefore the most efficient fine bubble diffuser available and is ideal for retrofit applications as a simple drop in product for tanks and ponds in Aquaculture and Waste Water Treatment.

Hand-held oxygen and temperature meter with NFC tags and Bluetooth technology for easy data transfer to Cobália. The Polaris C DO meter is a high-performance, low-cost and almost maintenance-free meter for measuring dissolved oxygen and temperature. The meter is sturdy, easy to use and has an extensive longevity making it ideal for harsh conditions. Polaris C DO can store up to 2500 complete data sets, including time and date stamps. The logged data is stored in the meter or can be transferred to Cobália using Bluetooth.Scan the Cobália NFC tag of the tank and all data will be uploaded to your “digital farm”. Tank specific data assigned to the tags will be stored in Cobália for analyses on temporal variations, multivariable analyses on performance and for the generation of graphs. The meter has a built-in self-check of all hardware, automatic barometric pressure compensation and a notably short response time. With this meter, you get the high-quality associated with OxyGuard technology and a product that will serve you well for many years. Instruction Manual
