Equipment

Esders OLLI is a professional multi-gas detector made in Germany, designed to protect personnel working in manholes, chambers, shafts and other confined or enclosed spaces. Depending on the configuration, OLLI monitors oxygen (O₂), combustible gases and toxic gases, including H₂S, CO and CO₂. If hazardous gas concentrations or unsafe oxygen levels are detected, the operator is immediately warned by acoustic, optical and vibration alarms. OLLI is available as a diffusion version or with an integrated sampling pump, allowing the atmosphere inside a confined space to be checked before personnel enter.

B Meters WDE DN500 is a horizontal Woltmann (turbine) type water meter equipped with a pulse output (IWM-PL3 / IWM-PL4), designed for DMA (district metering area) applications. It provides accurate flow measurement and is compatible with flow and pressure loggers. The device can be integrated into existing SCADA systems or used with the logger manufacturer’s data platforms.

PermaNET+ is an award-winning leak detection system that combines an advanced acoustic sensor with reliable telemetry technology to create a permanent, connected network for continuous leakage monitoring. As the next evolution in noise logging and leak detection, PermaNET+ offers a practical and scalable solution designed for utilities that need to monitor large and complex water networks efficiently. Fully compatible with Google Maps, the system provides real-time visualisation of logger locations, helping leakage teams to quickly identify and prioritise leak events across their network.

The Roediger Vacuum Compact Station Comp VS – Type 360 is the largest compact vacuum station designed for vacuum sewer systems, sanitary engineering and railway infrastructure. The station combines outstanding suction performance, reliable operation and a compact space-saving design.

Carbon Probe Set T-Handle is an accessory for the Esders HUNTER Tracer Gas system, designed for H₂/N₂ tracer gas leak detection both indoors and in external utility networks. The T-handle design provides comfortable operation and precise gas detection in various ground and surface conditions.

High-sensitivity hydrophones are designed for leak detection in pressurised water mains using the acoustic correlation method. The sensors capture leak noise transmitted through the water column and deliver a precise signal to the correlator for analysis. Fully compatible with Ovarro correlators (Eureka2, Eureka3, Eureka5), hydrophones enable accurate leak position calculation based on advanced signal processing. Hydrophones are typically installed on hydrants or dedicated access points, ensuring direct acoustic contact with the water column inside the pipe. Using correlation technology, leak localisation can be achieved over long distances: Up to approximately 2 km in metallic pipelines Up to 600–800 metres in polyethylene (PE) pipelines (depending on pipe diameter, internal pressure, background noise levels and site conditions) This makes hydrophones particularly effective for large diameter transmission mains and long-distance correlation applications.

AQ Smart Hydrant is a smart fire hydrant with flow and water consumption monitoring, providing continuous pressure and temperature supervision in real time. The solution is designed for remote hydrant monitoring and water network control.

The XT4 NANO magnetic manhole cover lifter is an ultra-compact tool designed for lifting medium to heavy manhole covers. It features an extendable handle that can be securely locked in both closed and extended positions using a spring-button locking system, ensuring safe and comfortable operation. The innovative handle design includes a release pin for cast-iron covers and allows direct connection with APS80 and APS90 wheeled levers, increasing versatility and ease of use in the field. A compact, reliable solution for professional utility and maintenance operations.

Esders GasCar Laser HUNTER – Vehicle-Based Natural Gas Leak Detection System The Esders GasCar Laser HUNTER is a professional vehicle-mounted system for natural gas leak detection and inspection of underground gas pipeline networks. The system uses the highly sensitive Laser HUNTER gas analyzer to detect even very small traces of gas escaping from buried pipelines. During inspection, the system simultaneously records gas concentration, vehicle speed and GPS position, allowing large sections of gas distribution networks to be surveyed efficiently and systematically. The system is available as GasCar Laser HUNTER Standard with one analyzer or GasCar Laser HUNTER Plus with two analyzers, allowing the air samples from the left and right sides of the vehicle to be analyzed separately for improved leak localization. The system meets the requirements of DVGW Technical Guideline G 465-4-3 (M) for the inspection of underground gas pipelines.

HWM PermaNET Trunk Main (TM) – Permanent Leak Monitoring for Trunk Mains PermaNET Trunk Main (TM) is an advanced solution for continuous leak monitoring on trunk mains and large-diameter pipelines. It is designed for critical water infrastructure where high reliability, precision, and real-time visibility are essential. By combining high-sensitivity acoustic sensors, support for external hydrophones (Hydrophone 2), and GPS time synchronisation, PermaNET TM enables effective leak detection and correlation over long distances, including plastic and other non-metallic pipelines.

XT5 is an ultra-compact magnetic manhole cover lifter with a rigid handle and integrated hook lever for mechanical lifting. The new magnetic plate provides up to 300 kg lifting force, ensuring safe and efficient operation.
