Designed to distribute water to a road surface in a controlled manner, ETT’s CDR (Constant Deposition Rate) Spray Head maintains a spray pattern with minimal variation in width and deposition rate. Parameters such as pump speed, pressure and ground speed are taken into account to achieve consistent spray coverage, regardless of the truck travel speed.

The ETT Intermittent Spray function ensures safe ascent and descent on steep gradients for heavy vehicles by minimising potential wet road slipping segments thereby creating strategic dry road intervals.

The CDR Spray System ensures that the correct droplet size is achieved across the entire flow range. Conventional spray systems cannot achieve this and regularly emit droplets too big that create pools, or droplets too small that are more susceptible to wind.

EVEN GRADIENT WATERING 
Traditional spray systems are prone to spraying excessive water on sloping gradients, thereby increasing the risk of large mining vehicles sliding. By comparison, the CDR Spray Head ensures an optimal amount of water is sprayed onto the ramp, which ensures no water pooling or uneven distribution of water.

CONVENTIONAL ON/OFF SPRAY SYSTEM 
Conventional spray systems provide little-to-no control of precise water deposition. With the hydraulically driven pump dependent on engine rpm, the pump flow rate provides an inconsistent spray; and conventional nozzles offer no automatic orifice adjustment. Therefore, the spray width cannot be kept constant.

AUTOMATED CONSTANT SPRAY CONTROL 
The CDR Spray Head applies an even spray of water across the targeted area. With automated constant spray control, water distribution remains even with zero pooling and significantly reduced road damage, regardless of the truck engine speed or road speed.
