Since TFD is rooted in first principles engineering, many clients have partnered with us to provide them with testing services as an independent third party.
Most tests are custom tests; however, over the years, TFD has developed significant competency in both industrial cooling, cooling tower and automotive testing.
Custom Testing
COOLING TOWER PERFORMANCE TESTING.
TF Design is uniquely equipped to perform independent Cooling Tower tests. These tests are typically done to the BS4485 standard, but a CTI test is also possible. At this stage, TFD is not CTI certified, but if a client requires this, we are appropriately positioned to obtain certification.
Our logger system has been custom-built to allow us to test multiple cooling towers at once, cutting down on the time required for tests, and side-by-side comparison of cooling tower performance at the same conditions. The test system has been developed to obtain accuracies of 0.03˚C.
Our instrumentation per tower is outlined in the table below:

We also built the largest traversing pitot tube in South Africa, allowing us to traverse up to a 3m hot water supply duct.
