What Makes Oil‑Free Hydrogen Compressors Essential for 70 MPa Refueling?

Introduction As hydrogen fueling stations expand globally, meeting the rigorous requirements of 70 MPa (700 bar) refueling becomes a mission-critical challenge. Only oil-free hydrogen compressors deliver the purity, reliability, and operational safety essential for such ultra-high-pressure environments. In this article, we explore why they are indispensable for modern hydrogen infrastructure. 1. Zero Oil Contamination = Ultra-Pure H₂ The main purpose of an oil-free hydrogen compressor is to completely eliminate lubricants from the compression stage. At 70 MPa pressures, even trace oil can degrade fuel-cell stacks and fuel infrastructure. Oil-free designs—such as piston or diaphragm compressors—use dry seals and non-contact surfaces, ensuring zero oil carryover into hydrogen streams. This purity is mandated by international […]

How Do Digital Twin-Enabled Compressors Slash Maintenance Downtime?

Downtime is one of the most expensive and disruptive problems in industrial operations. For companies relying heavily on compressed air systems—such as those in the chemical, petrochemical, and manufacturing sectors—unplanned compressor failures can result in production halts, contract penalties, and substantial financial losses. This is where digital twin-enabled compressors are transforming the landscape. In this article, we explore how integrating digital twin technology with industrial gas compressors helps slash maintenance downtime, and how companies like KEEPWIN are leading the way in delivering intelligent, predictive, and cost-effective compression solutions. What Is a Digital Twin in Compressor Technology? A digital twin compressor is a virtual model that mirrors the real-time operation, health, […]

Keepwinが高精度17-4PHピストンロッドを45日で納品した方法

精度と緊急性が出会うとき：Keepwinが17-4PHピストンロッドで欧州の顧客を救った方法 はじめに工業生産では、部品に1つでも欠陥があると、コストのかかる遅延が発生し、顧客の信頼が損なわれる可能性があります。そのため、賢明なバイヤーはスピードと精度を兼ね備えたパートナーを求めます。このケースは、Keepwin Technologyがどのようにして供給危機を解決し、45日以内にクラックのない17-4PH高精度ピストンロッドを出荷したかを示しています。危機まず、欧州のコンプレッサーメーカーが、他で調達したピストンロッドに目に見える亀裂を発見しました。そのロッドは使用不可能であったため、プロジェクトは違約金や契約違反のリスクを抱えていました。そのため、顧客は信頼できるメーカーを早急に必要としていました。Keepwinの選択調査と紹介の後、クライアントはKeepwinに連絡しました。すぐに当社のエンジニアが図面を確認し、H900 [...] 続きを読む
