Delta range

Product catalog summary

Introduction
The document provides an overview of the DELTA® range of chains, designed to address specific application issues such as wear, corrosion, and lubrication challenges. These chains are engineered for high resistance to abrasion, oxidation, and corrosion, making them suitable for demanding environments.

Specifications and Features

DELTA® Treatment: Applied to pins for high abrasion and oxidation resistance. The treatment achieves a hardness of 1800 HV, enhancing durability.
Anti-Corrosion Coating: RoHS compliant, free from hexavalent chrome, providing exceptional corrosion protection.
Temperature Range: Functional in environments from -30°C to +130°C.
Friction Reduction: DELTA® articulation has a lower coefficient of friction compared to case-hardened ones, delaying seizure.
Wax Lubrication: New generation wax reduces friction and postpones the need for re-lubrication.
Bi-Conic Bushes: Increase the pin/bush work surface for uniform mechanical stress distribution, improving wear resistance.

Solutions for Specific Problems

Wear (Elongation): DELTA® HR Chains are recommended for dusty or abrasive environments to reduce elongation and increase lifespan.
Corrosion: DELTA® Titanium 2 Chains offer anti-wear and anti-corrosion protection, serving as an alternative to stainless steel.
Lubrication: VERTE® Chains operate without oil, suitable for humid environments or where maintenance is challenging. They reduce maintenance costs and risks associated with oil use.

Advantages

Extended lifetime in severe applications.
Productivity optimization by reducing production stops.
Average savings of 33% on life costs compared to standard chains.
Higher mechanical characteristics than standard stainless steel chains.
Significant reduction in maintenance costs and risks.

Conclusion
The DELTA® range offers specialized solutions for various industrial challenges, enhancing chain performance and reducing operational costs. The document highlights the technical innovations and benefits of using DELTA® and VERTE® chains in specific environments.

DELTA® RANGE YOUR PROBLEM: WEAR (ELONGATION) My chain works in a dusty or abrasive environment. My chain elongates quickly. I would like it to last longer. OUR SOLUTION: DELTA® HR CHAINS The anti-wear chain for demanding applications • Unequalled hardness of the treated pins - even with big diameter - thanks to DELTA® thermochemical treatment invented and developed by SEDIS, allowing to reach hardness of 1800 HV. ▷ Remarkable resistance to abrasion and oxidation. • Coefficient of friction of DELTA® articulation lower than case hardened ones. ▷ Seizure postponed further. Comparison of a case hardened...

YOUR PROBLEM: LUBRICATION My chain works in a humid atmosphere. My chain operates in an environment where maintenance is difficult or even impossible. My maintenance costs are too high. I would like an environment-friendly chain. OUR SOLUTION: VERTE® CHAINS (“or Green chains”) All the power of SEDIS chains without the maintenance constraints A regular lubrication of chains guarantees their life time. However it is sometimes and for many reasons difficult to implement. The solution in a clean environment is the use of VERTE® chains, which operate without oil input, even in a humid atmosphere and...
