The JBL Regulator Professional (Ref 646720) is a high performance precision regulator equipped with an integrated solenoid valve for automated management. Indispensable for plant fertilization or feeding a limestone reactor in reef.
The JBL PROFLORA CO2 REGULATOR PROFESSIONAL is the ultimate tool for demanding aquariophiles. This safety regulator returns the internal pressure of the bottle (about 60 bar) to a stable working pressure of 1.5 bar, allowing a surgical accuracy adjustment thanks to its fine needle valve. 🛠️
Equipped with a 12V solenoid valve pre-mountedThis regulator allows automatic nocturnal break (to save CO2 and avoid useless phrases) or control via a pH controller. Its operation is silent and its electricity consumption very small.
One of the great strengths of this model is its modularity:
| Feature | Detail |
|---|---|
| Mark | JBL |
| Name | Regulator Professional |
| Reference | 646720 |
| Equipment | 2 manometers + 12V solenoid valve |
| Working pressure | Preset at 1.5 bar (adjustable) |
| Compatibility | Disposable and rechargeable bottles |
💎 The opinion of the Expert Recifart: This regulator is ideal for reefists using a limestone reactor (RAC). The solenoid valve makes it possible to couple the regulator to a pH meter to inject the CO2 only when the internal pH of the reactor exceeds the setpoint, thus ensuring a perfect dissolution of the substrate without waste.
Yes, the JBL Regulator Professional is perfectly adapted to power the limestone reactors (RAC) in Aquarium reef, in addition to its classic use for fertilization of freshwater plants.
The first pressure gauge displays the internal pressure of the bottle (about 60 bar), while the second indicates the working pressure set (about 1.5 bar), allowing you to precisely control the remaining battery life and the outgoing flow.
The solenoid valve allows automatic cutting of the CO2 intake. It can be connected to a timer for a nocturnal break or a pH / CO2 controller for automated control according to the needs of your aquarium.
Yes, this model is versatile. It adapts to rechargeable bottles (W21.8x1 / 14 thread) and, by unscrewing the knurled nut with an Allen key, it becomes compatible with the M10x1 thread of the single-use CO2 bottles.
