The Dupla CO2 Set Delta 400 Pro is a product of the highest quality and reliability. Stringent and constant quality control in the production process in compliance with ISO 9001 results in a product with a long life cycle.
The CO2 Set Delta 400 is recommended for aquaria up to approximately 400 litres in capacity. The set is based around the Dupla CO2 Reactor 400, a unique and sophisticated device for optimum CO2 infusion. In the Reactor 400, water from the filter pump by-pass trickles over the internal cascade, mixing with inflowing CO2 gas, thereby creating a large increase in CO2 diffusion capacity.
The Set 400, also includes the Dupla CO2 pressure reducer fitting Delta which reduces the cylinder pressure from approx. 60 bar, to a constant working pressure of 1 bar. A Duplasafe Valve is included to prevent back-syphoning, along with a CO2 Permanent Test, two 'F' pieces for tapping off a water supply bypass to the reactor, quality silicone tubing for water and CO2 supply and a cleaning brush set for the reactor. Just add cylinder.
Included in this kit:
- 1x CO2 Reactor 400 - The Reactor 400 causes a bypass of water from the filter pump to trickle over the internal cascade, mixing with inflowing CO2 gas. This enables a large diffusion capacity. The capacity of the Reactor 400 may be reduced for small aquariums where no automatic control is employed. By removing one of the vent plugs on the reactor body, six different capacities may be selected.
- 1x Safe-Ventil - This non-return valve is used to prevent water from flowing back along the CO2 line, and causing damage to the Magnetic Valve or Pressure Reducer. It should be installed between the Magnetic Valve and the Reactor.
- 1x CO2 Fitting Pro - High pressure gauge, low pressure gauge, needle valve and adjustable pressure reducer in one convenient unit. High control and accuracy, precise bubble rate adjustment, easy to handle knurled screw for cylinder connection and precise and easy adjustable fine needle valve.
- 1x Dupla Plant 24 - 10ml bottle daily fertiliser.
- 1x CO2 test solution, chart & vial - testing of the carbon dioxide content in freshwater.
- 3x Connector pieces for filter - 1x 16/22, 1x 12/16 & 1x 9/12
