DIR Regulator Set – V2 1st Stage + TEC2 2nd Stage

Mirrored premium twinset configuration compliant with DIR standards. Includes two asymmetrical V2 ICE diaphragm first stages with "V" routing, ultra-compact top-of-the-range second stages, and accessories for cold water diving.

The Tecline V2 ICE TEC2 DIR Style Regulator Set, available at DIR-STORE, represents the pinnacle of evolution for twinset management in extreme environments, such as deep cave or under-ice explorations. This top-of-the-range package combines the exclusive asymmetrical geometry of the V2 ICE mirrored first stages with the advanced fluid dynamics of the latest generation TEC2 second stages. Thanks to the angled "V" routing, the hoses run perfectly straight and parallel to the cylinders. This design eliminates forced hose bends, completely frees up the diver's neck area, improving trim and ensuring immediate access to the valves in an emergency (valve drill). Certified well beyond the requirements of the stringent European EN250A standard, it offers superior breathing comfort in the most severe conditions.

Technical Features:

• Dual V2 ICE First Stage (Asymmetrical Mirrored Design for Twinset): Built from high-quality marine bronze, the V2 ICE first stages feature a balanced diaphragm mechanism with a dry chamber (Dry Chamber) and Cold Kit for icy waters. The pair is rigidly divided into a right body (2 LP outlets / 1 HP outlet) and a left body (2 LP outlets / 1 HP outlet) to allow the hoses to run in parallel without twisting points. Maximum operating pressure at 300 bar.
• Dual TEC2 Second Stage (DFS Technology and Ultra-Comfort): The pneumatically balanced second stages implement the innovative Direct Flow System (DFS) technology. This architecture optimizes the internal fluid dynamics of the gas, drastically reducing the total work of breathing (WOB) at any depth, regardless of the residual pressure in the cylinders.
• Anti-Freeze and Mechanical Shielding: The structural polymer cover is frontally shielded by a solid stainless steel ring to withstand strong mechanical stresses or impacts in confined environments. The internal metal parts benefit from a dedicated heat exchanger at the connection point and a protective non-stick Teflon coating.
• Dual Adjustment and Safety: Both second stages integrate a lever for manual adjustment of the Venturi effect (essential to prevent accidental free-flow of the backup second stage positioned at the neck) and a micrometric knob to calibrate the inspiratory effort.
• Customizable DIR Style Hose Geometry: The set includes high-quality black LP hoses precisely sized for their respective technical roles, with the option to choose the desired length:
  
• LP Hose for Donor Regulator (Long Hose): 1.93 m / 2.00 m / 2.10 m
• LP Hose for Backup Regulator (Necklace): 0.61 m
