Technisub ARALU Twin Cylinders A Rare Piece of Scuba Innovation

The Technisub ARALU twin cylinders represent one of the most fascinating periods in scuba diving history. Originally developed in Italy during the early 1970s, this distinctive twin-cylinder system showcases Technisub’s bold approach to improving diver performance, air capacity, and overall design.

At the time, manufacturers were actively experimenting with new configurations. As a result, the ARALU bibombola system emerged as a compact and visually striking solution that pushed beyond traditional scuba equipment.

A Unique Moment in Diving History

The Technisub ARALU twin cylinders were developed during a period of rapid innovation in scuba equipment. At this stage, manufacturers were exploring ways to increase performance and efficiency.

In particular, they focused on:

Increasing available air supply
Improving diver balance and comfort
Creating more efficient underwater systems

Consequently, this twin-cylinder configuration reflects an early move toward higher-capacity setups. In turn, divers could achieve longer bottom times compared to single-cylinder systems of the same era.

Key Features

Twin-Cylinder (Bibombola) Configuration

The dual-cylinder design provides several advantages. Firstly, it increases overall air capacity. Secondly, it improves weight distribution. Finally, it allows for extended dive duration.

Original Technisub Manifold System

The system features a solid crossbar manifold with individual control knobs. Unlike modern systems, this setup reflects early European twin-cylinder engineering.

As a result, it highlights:

Period-correct construction
Simple and robust design
Unique vintage functionality

Protective Coating and Styling

The distinctive red base coating offers both function and style. On one hand, it provides protection against impact. On the other hand, it enhances corrosion resistance.

In addition, the silver upper body creates a bold contrast. Together, these elements deliver a classic 1970s industrial diving aesthetic.

Compact European Design

Unlike many modern twinsets, ARALU tanks were designed with efficiency in mind. Therefore, they are:

More compact
Easier to handle
More hydrodynamic for their time

Important Notes (Collector Awareness)

As with many vintage systems, there are a few important considerations. Firstly, these tanks are primarily suited for collection or display. Secondly, the manifold system differs from modern DIN configurations.

Therefore, any operational use should only be undertaken after professional inspection. Ultimately, this is a historical item that should be preserved carefully.
