DIR Regulator Set – 1st Stage V2 + 2nd Stage TEC1

Ultimate and mirrored configuration for twinsets compliant with DIR standards. Includes two asymmetrical V2 ICE diaphragm first stages with optimized "V" hose routing, high-performance adjustable second stages, and accessories.

The Tecline V2 ICE TEC1 DIR Style Regulator Set, available on DIR-STORE, is a high-end solution designed specifically for technical divers and cave divers using twinsets in extreme conditions, including ice exploration. The system is based on mirrored V2 ICE first stages (one right and one left) featuring the exclusive "V" geometry. This asymmetrical design allows the hoses to run remarkably linearly and hydrodynamically along the cylinders' profile, completely freeing up space behind the diver's neck, improving trim in the water, and ensuring immediate and unobstructed access to the valves during emergency maneuvers (valve drill). Certified well beyond the requirements of the stringent European standard EN250A, it offers flawless delivery at any depth.

Technical Features:

• Dual V2 ICE First Stage (Mirrored Asymmetrical Design for Twinset): Constructed from high-quality marine bronze, the V2 ICE first stages operate with a balanced diaphragm mechanism equipped with a sealed dry chamber (Dry Chamber) and Cold Kit for icy waters. Unlike traditional models, the pair is divided into a right body (2 LP ports / 1 HP port) and a left body (2 LP ports / 1 HP port). This ultra-clean layout is geometrically angled to run the hoses in parallel and eliminate any forced bends. Maximum operating pressure at 300 bar. The pair weighs only 1580 g.
• Dual TEC1 Second Stage (Smooth Breathing and High-Flow): The two pneumatically balanced second stages maintain minimal inspiratory effort at any depth, compensating in real-time for pressure variations within the cylinder. The classic design ensures precise delivery and extremely simple field maintenance, while the casing is reinforced by a protective anti-shock aluminum perimeter ring.
• Flow Control and Thermal 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 breathing effort. A metal heat exchanger on the hose prevents freezing at the point of maximum gas expansion.
• 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:
• Donor Regulator LP Hose (Long Hose): 1.93 m / 2.00 m / 2.10 m
• Backup Regulator LP Hose (Necklace): 0.61 m
