Safety, Reliability and Versatility
TEMEC CMXT Autonomous Gate
Guarantee of constant regulation and autonomous opening for overflows, even in adverse weather conditions. Completely autonomous, robust and reliable solution.
It allows modifying the regulated levels by manual or automated set point changes.
► Features
These solutions involve civil works in the chambers of small or medium-sized power plants, including one or more gates controlled by floats and ballast weights, designed to simultaneously maintain a minimum upstream level, a predefined downstream level and a maximum downstream level. These devices open or close autonomously according to variations in water level, ensuring the constancy of the downstream level. The absence of motors and sensors contributes to the robustness and reliability of this equipment.
The gates allow set point changes on the regulated levels in case the customer requires it, manually or with the automation of small devices inside the gate. This automation is focused on the management of the set point change, not on the adjustment operations of the gate itself in case of water fluctuations, a situation that will always continue autonomously by the floats of the gate, which guarantees an efficient, smooth and reliable operation under the most severe weather conditions.
The MXT gate's versatility makes it possible to maintain a level in order to guarantee optimal operation of the turbines, to establish a specific level in the downstream canal which, if the flow curve of the section is available, translates directly into a specific flow rate. In addition, it allows the accumulation of unused flow in the upstream canal for later use in case of changes in the inflow or to generate energy at higher yield times.
In situations where the maximum upstream level exceeds a certain range, the gate opens automatically to prevent overflows in the upstream zone, providing total safety to the chamber.
► Tips about use

Safety and Reliability
TEMEC CAR1 Autonomous Gate
Guarantee of constant upstream regulation, limiting the inflow to the demand and with autonomous opening in case of overflows. Fully autonomous, robust and reliable solution.
This solution does not allow modification of the regulated and maximum discharge levels once defined on the construction site.
► Features
These solutions involve civil works in the chambers of small or medium-sized power plants, including one or more gates controlled by floats and ballast weights, designed to maintain a specific level upstream and in a precise way. These devices play a critical role in maintaining the maximum level in a chamber, adjusting autonomously according to the flow to be discharged. This device gives priority to the hydroelectric power plant by allowing the controlled evacuation of excess flows through the bottom of the canal, also helping to remove sediments. In the event of an abrupt generator output and the consequent rejection wave into the canal or chamber, the response is immediate and autonomous. The absence of motors and sensors contributes to the robustness and reliability of this equipment.
In the event of a turbine shutoff, the gate is initially closed to maintain the generation level. When the turbine shuoff occurs, the emergency systems are activated to protect the power plant, generating a back-pressure wave that extends upstream. The upstream gate detects this peak level rise and opens automatically to discharge the excess flows. Once the wave is relieved, the gate drops open to allow the canal flow to pass through without emptying the chamber, all automatically and without the intervention of motors, sensors or manual monitoring.
Compared to a weir, where the maximum level is the same as the discharge for the design flow, an AR1 gate allows the generation of a larger usable head, of the order of the difference between the weir wall and the maximum level. This value, especially relevant for high flow and low head, can result in significant differences in the generated energy.
This solution does not allow set point changes on the regulated level in case the client requires it, because it is a set parameter once the civil work is defined.

Overflow Security
Autonomous Safety with Siphons
To dominate in chambers with autonomous discharge of excess water. Requires compact civil works.
This solution does not allow modification of the discharge levels once defined on the construction site.
► Features
These solutions involve civil works in the power plant chambers, where siphons play an effective role by gradually evacuating excess flow above a specific level, avoiding any pulses. Compared to weir spillways, siphons have a significant advantage by reducing by forty to fifty times the length required to obtain the same level elevation and the same evacuated flow.
This evacuation method, characterized by its progressive discharge, is highly efficient in the management of excess flows. The ability of the siphons to maintain a continuous flow without generating pulses makes them an outstanding option compared to conventional spillways.
In addition, the significant reduction in length required to implement siphons results in practical and spatial benefits, making them a compact and efficient solution for controlled flow management in a multitude hydraulic applications.
The absence of moving parts, motors or sensors contributes to the robustness and reliability of this equipment.
