New weld purge monitor Huntingdon Fusion Techniques has introduced a new dedicated Weld Purge Monitor.

to read accurately as oxygen levels fall below the atmospheric reading of 20.94%. When the battery life is too low to provide sufficient power to run the PurgEye100 correctly, a battery symbol appears on the screen to warn the operator to change the battery. Similarly, a sensor symbol will appear on-screen to alert the operator to change the oxygen sensor.

to be returned to the factory for yearly calibration.

Using a tripod mount, the monitors can be located securely in an accessible viewing position without having to resort to additional clamping fixtures. The PurgEye 100 has an algorithm in the software to correct the reading at low oxygen levels, to ensure accuracy and repeatability of readings. Most low cost oxygen monitors are made for oxygen measurement at breathing levels for personal safety, rather than welding, and they are unable

Having developed the models MKI to MKV in a particular style, the company has embraced advanced technology to create a new instrument, designated PurgEye™100, that offers significant advances over previous models. Features include integrated auto- calibration, requiring just the press of a button to calibrate both at ambient and at the lowest oxygen reading, and providing instant calibration at 0.01% O 2 . It also removes the need for monitors

Energy-efficient systems for district cooling District cooling is becoming increasingly important. Utilising the waste heat given off from numerous potential sources of energy is a highly energy- efficient approach that also protects the environment. Brugg Pipe Systems is accommodating this development by launching an extensive system for use in the district cooling technology sector. sources of energy, including waste incineration plants, industrial facilities, combined heat and power plants or natural sources such as water in rivers, lakes or the sea. The use of solar and geothermal energy for cold water production or district cooling is also on the increase. account of the specific requirements that arise in the cooling sector, and feature excellent insulation values. The compact pipe composite prevents the formation of longitudinal water and is self-compensating.

The new Coolflex and Coolmant product lines are designed to ensure ease of installation. Tried-and-tested jointing and additional insulation components provide reliability and safety during operation. Brugg Rohrsystem AG – Switzerland pipesystems@brugg.com www.pipesystems.com

With its Coolflex and Coolmant product lines, Brugg offers a range of pipe systems and installation components for district cooling distribution. The flexible Coolflex system is suitable for smaller district cooling networks, while the rigid Coolmant system was developed for wide-area networks. The products take

To an increasing extent, district cooling supply networks are becoming established as a future-oriented, green alternative to conventional cooling technologies. District cooling networks can be supplied from various
