No room for compromise on quality

It produces a large spray pattern that allows for a longer float time, thereby increasing the evaporation rate. The can- non works by atomising the water through 38 nozzles, which are available in PVC, stainless steel, brass or nylon, depending on the application. The unit discharges 21,3 litres a minute through each nozzle, with the 55 kW pump delivering a maximum pressure of 10 bar. The droplet size is 150 µ to 180 µ, with a throw distance of 80 m to 110 m. The I-VAP 500 features an integrated fan and nozzle ring design, together with a high-pressure hose and a 40 mm cam-and- groove quick disconnect female coupling. It boasts a premium efficiency 0,10 kW oscil- lator motor, and is supplied with a 50 mm electrical cord of up to 30 m, with other options being available. Morne vanWyk, I-CAT, tel 086 112 4228 One of the major differentiators that Andrew Mentis flooring products have is that they are subjected to an extensive quality manufacturing process. “We do not compromise on quality, which means that under no circumstances are we pre- pared to cut corners. Apart from the strict controls under which our products are manufactured, we do not use commercial quality mild steel.We have standardised on SAE 1008 which ensures consistency and also prevents damage to our machines.” Andrew Mentis was established more than 65 years ago and has numerous ref- erence bases in a number of industries in South Africa. Operating from large premises in Elandsfontein, the company manufactures floor grating, expanded metal and hand-railing systems in mild steel and stainless steel, and guard-railing. Elaine van Rooyen, Andrew Mentis, tel (+27 11) 255-3200 why we believe there is an urgent need to educate the market about this problem,” van Rooyen says.

Continued economic pressure always produces a conundrum when it comes to purchasing decisions, especially with an increased focus on reducing costs. Andrew Mentis, however, raises the concern that there may be a very real danger that infe- rior quality products will be used, and this will have a detrimental effect on safety. Elaine van Rooyen, Marketing Manager at Andrew Mentis, explains that this is

ent weather conditions, I-CAT Technical Manager Morne Van Wyk explains. This latest wastewater treatment and management system from I-CAT Water Solutions ensures that wastewater from mine sites does not enter the general envi- ronment and thereby contaminate water further downstream. A particular bene- fit of the I-VAP 500 is its low energy-use to evaporation ratio, Van Wyk notes. The I-VAP 500 can cover 32 000 m 2 , with an automatic oscillation option of up to 359 deg. An integrated turntable bearing allows the operator to over- ride the oscillator manually in order to reposition the fan barrel quickly. In addition, the cannon has an adjustable angle of throw, with a height adjust- ment of 7 to 45 deg. especially true for its flagship product. “It is critical that when purchasing flooring grating that a quality product with structural integrity is procured as this material is most often used as access walk- ways and platforms and therefore needs to be able to hold the required personnel and equipment without any cause for concern over their safety,” she says. Mentis floor grating is engineered to take specific loading which ensures opti- mum safety of the people walking on or working in those areas. Van Rooyen raises the issue that while cheaper products may well look identical, and to the untrained eye will not have any apparent physical difference, they may not be capable of car- rying the requisite load. “Often it is only after the floor grating has been installed and in use for some time that the danger of its reduced load-bearing capacity will become apparent. And this is

Evaporation cannon handles mine wastewater After identifying the need for an environ- mentally-safe evaporation system to reduce excess wastewater at mines, I-CAT Water Solutions developed the I-VAP 500 evapo- ration cannon, which is capable of handling 500 m 3 per 12-hour day. The evaporation rate is 60 % to 65 %, depending on ambi-
