DILO

DILO is a German manufacturer specializing in SF6 gas handling technology for high-voltage electrical switchgear. The company produces a comprehensive range of equipment for the recovery, storage, purification, and analysis of sulfur hexafluoride (SF6) — a gas widely used as an insulating and arc-quenching medium in gas-insulated switchgear (GIS), high-voltage circuit breakers, and power transformers operating at transmission and distribution voltages.

DILO's SF6 service equipment enables maintenance operations at electrical substations and power facilities while ensuring that SF6 is handled safely and in compliance with environmental regulations governing greenhouse gas emissions. Their purity testers and gas analyzers are used to verify SF6 quality and detect moisture or decomposition byproducts before and after maintenance procedures.

Key Product Lines

• SF6 Purity Testers — portable instruments for measuring SF6 gas purity, moisture content, and decomposition products in GIS and circuit breakers
• SF6 Service Carts — equipment for recovering, evacuating, and refilling SF6 from high-voltage apparatus
• Gas Analyzers — instruments measuring SF6 concentration, humidity, and SO2 for quality verification and leak detection

Industries Served

DILO equipment is used by electric utilities, transmission system operators, industrial power facilities, and electrical maintenance contractors working on gas-insulated switchgear, high-voltage circuit breakers, and power transformers. Their instruments are essential at substations operating at medium and high voltage levels where SF6 gas management is required for safe and compliant maintenance.
