Description

This Hiwi branch enables you to supply several tanks with one CO2 cylinder. It comes with an integrated check valve in the needle valve, which secures the CO2 System from back running water. Several diffusers or external reactors can be run on this CO2 splitter.

The branch is equipped with several needle valves that guarantee a precise CO2 dosage.

In order to put the branch into operation, you connect the branch with tubing. A 6/4 mm tubing connection is mounted as a standard and fixated with glue. With a CO2 high pressure tube (for example LDPE or PURE) the connection to the pressure reducer is made.

Features

  • Branch with integrated check valve in the needle valve
  • Enables you to connect several tanks to your CO2 system
  • Clamps for wall mounting included

Hiwi

Hiwi is a renowned German manufacturer of CO2 pressure regulators. The highest level of quality and a long useful life are in their focus. These high quality standards do not exclude attractive prices, though.

Especially in aquascaping, the addition of CO2 for the plants is something very basic, and thus it is really important to choose good CO2 supplying equipment. Hiwi meets even the highest quality standards in every aspect und is thus the best choice when it comes to CO2 pressure regulators.

I'd like to connect two bubble counters directly to the splitter; one comes with the pressure reducer. Where can I get the matching second one?

Unfortunately, the Hiwi bubble counter for mounting on the needle valve is not available as a separate product.

I bought the CO2 Set Advanced Soda from you. Can this splitter be installed there? In what order then solenoid valve, splitter and bubble counter?

The splitter is connected using a CO2 high-pressure tubing. The components are installed as follows: pressure reducer - bubble counter - solenoid valve - splitter - diffuser. If additional bubble counters are installed, they must be placed between the splitter and the diffusers.

Very solid, a good way to supply several aquariums.

The distributor comes with mounts (for screwing). The needle valves can be adjusted quite finely, even though from a certain point they get stiff.

Sehr solide, gute Möglichkeit, mehrere Aquarien zu versorgen.

Der Verteiler wird mit Halterungen (zum Verschrauben) geliefert. Die Nadelventile können ziemlich fein eingestellt werden, wenn auch diese ab einem Punkt schwerfällig sind.
