DEMA MixRite 3 Proportional Injector USER MANUAL www demaeng com E mail sales demaeng com l 1066 DEMA User Manual The MixRite is powered by water flow with minimal loss of pressure The water engine powers the proportioning unit No external power is required The proportioning unit injects liquid additives in direct relation to the amount of water that passes through the motor and injects the additives into the water system The water engine action The suction and proportioning unit is built from a piston connected to the water engine from which it derives its movement The piston moves within a cylinder with a non return valve The movement of the piston within the cylinder causes the water to be injected and the required liquid additive to be drawn through a pipe inserted into a container It is possible to regulate the supply ratio between the additive and the water passing through the injector Water inlet gt Suction unit with adjustable proportional dosing l 1066 2 l 1066 DEMA Technical Data The MixRite operates in the following conditions From a minimum flow rate of 20 L H 0 088 GPM and up to 3 175 L H 14 GPM subject to the model Temperature not lower than 4 C 39 F and not higher than 40 C 104 F Water pressure between 0 2 Bar to 8 Bar 2 9 to 120 PSI The additive may be added to the water flow according to the required dosing perce
