30 WET NEWS SEPTEMBER 2014 WHAT'S NEW! Adapting from standard to tough bore conditions TT-UK has achieved a significant leap forward regarding technical capacity and economic efficiency with its new GRUNDODRILL 18 All Condition System, which can bore through various sand, soil or rock environ- ments. The combined unit adapts from standard drillings to the toughest bore conditions with optimal results. Once the pilot bore is prepared, the S-tube impeller helps overcome ragging pilot bore head is removed from the first drill rod string, which can then be exchanged with a suitable bore hole opener for each specific and individual soil/rock condition. The GRUNDODRILL 18ACS works with a twin tube drill rod. The inner tube is mounted inside the outer tube and prevents wearing contact with the outer tube while boring. The inner tube drives the bore head with the roller chisel transferring a torque of max. The spacious operator cabin revolves up to 90° and features a simple, user friendly touch screen display is controlled easily by the operator to manage all functions and manoeuvres. www. tt-uk.com Tel: 01234 342566 Prior to the release of the new S-tube, Grundfos approached a water company in the north of England with a view to involving it in the development and testing of this new impeller technology. A combined sewage and stormwater pumping station was selected that KalGUARD installation made easier Sentinel Commercial's solution to protecting commercial hot water systems from limescale, KalGUARD, is now easier to install and operate than ever before. The WRAS-approved KalGUARD system's new features are designed to fine-tune and speed the process further. The changes include a wall-mounting template to simplify the correct positioning of drilled holes. Easier access to screw points reduce the chance of dropping and losing screws. A four line, organic LED display ensures that values are easy to read in low light conditions or from a distance, which is handy since the units are often installed in awkward locations. In addition, the controller technology enables future firmware updates from Sentinel to be effected speedily, with minimal disruption and down time on site. Finally, the addition of an optional BMS pulse splitter enables water usage to be monitored by the building management system. KalGUARD is available in eight sizes ranging from 22mm to 108mm. www. sentinelprotects.com Tel: 01928 588330 Delivering accurate conductivity Sensorex has expanded its S8000 series modular electrode platform with the addition of the CS8000TC conductivity sensor. The new electrode delivers accurate conductivity measurement for cooling tower monitoring and a host of additional processing environments. The CS8000TC sensor integrates easily into in-line systems. Its keyed flange facilitates sensor orientation. A detachable cable assembly eliminates the need to pull cable through a conduit and sensors can be removed without tools for cleaning and calibration. Sensorex's S8000 series modular platform saves users time and money by configuring a custom system that can grow and change with process needs. The platform includes pH, ORP (Redox) and conductivity electrodes, a choice of mounting hardware, and a variety of electronics options including unity gain pre-amplifiers and blind 4 – 20mA transmitters. Sensorex said that if monitoring needs change, users can update the applicable module without replacing the whole system. www. sensorex.com Tel: +1 714-895-4344 had a history of pump blockages. The pre-trial pumps were tripping on a regular basis due to excessive ragging. The S-tube impeller started its field trial in 2010. During the whole pre-trial, trial and post-trial period, Grundfos worked closely with the client to develop and optimise the S-tube impeller design based on operator feedback during the test period, helping to perfect the hydraulic performance. After a year of trouble-free operation, the trial pump was lifted and the pump was then closely examined to see what suggestions for improve- ments could be gleaned from it. This feedback contributed to revising the impeller design and the pump. www. uk.grundfos.com Tel: 01525 850000
