Dynamic Scale Loop
The dynamic scale loop is a tube blocking system for the evaluation of scale inhibitors. The basic principal involves mixing two incompatible brines in a narrow bore test coil. Scale begins to form in the coil creating a differential pressure. The time taken for this formation gives an indication of inhibitor performance.
Techbox Systems manufacture units to suit all temperature and pressure requirements - from low pressure and temperature to pressures in excess of 6000psi and temperatures over 250°C.
Our standard test rigs are the L1 low pressure and H200 high pressure units.
We specialise in designing and manufacturing bespoke equipment to meet customer’s specific requirements.
Schematic
The H200 unit operates at up to 200 Bar and temperatures up to 200°C. The unit uses two preheat coils in addition to the test coil housed within a digitally controlled oven.

Typical result graph
The above graph show typical results. The untreated brine forms scale and starts to block the test coil after about 12 minutes (Blank). The test is then repeated with scale inhibitor present, firstly at 3ppm, automatically reducing to 2ppm after 45 minutes and finally reducing to 1ppm after 90 minutes. At about 110 minutes the test coil starts to block again indicating insufficient inhibitor. At this point the unit automatically cleans itself.
