DIR Regulator Set – 1st Stage V1 + 2nd Stage TEC1

Complete twinset configuration to DIR standard. Includes two monolithic V1 ICE diaphragm first stages with "V" hose routing and high-performance adjustable second stages.

The Tecline V1 ICE TEC1 DIR Style Regulator Set, available at DIR-STORE, is a high-end breathing system designed specifically for technical divers who demand millimeter-perfect and hydrodynamic hose routing on twinset configurations. By utilizing the "V" geometry of the V1 ICE first stages, this set allows for incredibly clean and parallel hose routing along the cylinders. This design minimizes bulk behind the head, provides total freedom of movement, and promotes perfect trim in the water, while also optimizing access to the valves in an emergency. Certified well beyond the strict requirements of the European EN250A standard, it offers constant breathing comfort and total protection against freezing.

Technical Features:

• Dual V1 ICE First Stage ("V" Geometry and Hydrodynamic Layout): Constructed from high-quality marine bronze, the V1 ICE first stages utilize a balanced diaphragm mechanism assisted by a sealed dry chamber and a cold kit. This system completely isolates the springs and internal components from ice, mud, and sediment. The "V" layout of the outlets naturally routes the hoses along the profile of the BCD bladder, preventing annoying cross-overs at neck level. Each first stage offers 4 LP and 2 HP ports, with a maximum operating pressure of 300 bar.
• Dual TEC1 Second Stage (Simplicity and High-Flow): The two pneumatically balanced second stages minimize inspiratory effort at any depth, compensating in real-time for cylinder pressure drop. The classic design ensures precise delivery and extremely simple field maintenance, while the casing is reinforced by a protective aluminum perimeter ring.
• Flow Control and Safety: Both second stages integrate a lever for manual adjustment of the Venturi effect (essential to prevent accidental free-flows on the backup second stage at the neck) and a micrometric knob to calibrate the inspiratory effort. A metal heat exchanger on the hose prevents the formation of ice crystals at the point of maximum gas expansion.
• Custom DIR Style Hose Geometry: The set includes high-quality LP hoses dimensioned to the millimeter for their respective technical roles: a long hose (1.93 m, 2.00 m, or 2.10 m) for the primary second stage (the donor) and a short hose (0.61 m) for the neck backup.
