Description
The Chihiros CO2 Pressure Regulator is a small, ready-to-use application for reusable CO2-cylinders that reduces the pressure of a CO2 gas cylinder from 57 bar to a working pressure suitable for aquaristics. Thanks to its unobtrusive design and compact construction, this pressure reducer does not take up any valuable space, meaning that the CO2-system can be placed discreetly in the base cabinet. Moreover, even when placed outside the cabinet, it does not distract from the view of the carefully designed underwater landscape.
The precise adjustment option provided by the fine needle valve and the high quality of workmanship make it possible to precisely adjust the CO2-supply for aquariums of all types. Aquascapes and also professional applications such as nursery tanks can be set to precisely defined CO2-concentrations with the help of the Chihiros pressure reducer, whereby the use of the Chihiros Bubble Counter is recommended to control the exact supply. The output pressure gauge shows a range of 0 to 90 psi (up to approximately 6 bar) and at the same time informs about the filling level of the bottle when the pressure decreases.
The pressure reducer is also available with a solenoid valve: Chihiros CO2 Pressure Regulator. For digital control, the pressure reducer can be upgraded with the Chihiros Controller for CO2 pressure reducer and solenoid valve. This can be operated and programmed via Bluetooth using the myChihiros app.
