Products > Open Canals
We provide integral solutions for Open Canal, with manufacturing and assembly of simple, robust and low-maintenance equipment, in order to guarantee its operation in a safe and long-term manner.
We have autonomous operation equipment, without the requirement of any external energy to be operated, and manual or automated equipment.
Autonomous equipment
This equipment operates on the principle of balance between a float and a ballast, which makes it possible to control the water level according to the project's demands.
- Mixed Level Control Gate
- Downstream Level Control Gate
- Upstream Level Control Gate
- Downstream Level Cylindrical Valve
- Dreinage Flap Gate
- Automatic Security Siphons
Automatizable equipment
These equipments are manually operated by lifting systems that are tested for the most extreme conditions. They can be automated by electric motors and remote controls, according to the requirements of the project.
- Flat Gate (sliding/sluice or wagon)
- Spillway gate
- Radial Gate
- Tilting Weir Gate (Overshot)
- Distributors (TEMEC's Módulos de Orificio)
- Remote Controlled Radial Gate (TEMEC's CST)
Autonomous equipment
► How they work
This equipment operates on the principle of a balance between a float and a ballast, which allows the water level to be controlled according to the requirements of the project. Within a range, the flow rate in the canal can fluctuate, and the gates will adjust their opening to maintain the desired level. Their operation independent of external electricity, automation, motors or human intervention makes them highly reliable and with minimal operation and maintenance costs.
Due to their role of constant level maintenance, these units can be combined to achieve:
- SUPPLY DISTRIBUTION: The gate maintains an upstream level, allowing excess flows to discharge. Until the bypass setpoint is met, the gate does not open.
- DEMAND DISTRIBUTION: The gate opens or closes according to downstream flow demand, increasing efficiency to almost 100% (pipe-like operation).
Mixed Level Control Gate
TEMEC CMXT
For installation in canals, rivers or reservoirs.
They allow maintaining a mixed regulation between their upstream and downstream levels, thus compensating for inflows and outflows.

Downstream Level Control Gate
TEMEC CAB1 y CAB2
For installation in canals, rivers or reservoirs.
They provide constant downstream water level control whatever the flow rate and the upstream level conditions or downtream demands.

Upstream Level Control Gate
TEMEC CAR1
For installation in canals or rivers.
They provide constant water level on the upstream side of the gate section, whatever the flow rate.

Dreinage Flap Gate
TEMEC CLD
For installation in rivers, to protect against backflow.
They prevent the flow of water in one direction and oppose its return in the opposite direction. Known as "Flap Gate", our design operates autonomously in the event of a small overpressure.

Automatic Security Siphons
TEMEC SFS
For installation in canals and reservoirs, for excess water evacuation.
They evacuate by progressive discharge, the excess of flow above a nominal level. They require less than 50 times the length compared to a spillway.

Downstream Level Cylindrical Valve
TEMEC CAB3
For installation in distributors in canals or outlets of reservoirs or dams.
They provide constant downstream water level control whatever the flow rate and the upstream level conditions or downtream demands.

Manual or Automatizable equipment
► How they work
This equipment is manually operated by lifting systems designed and tested for the most extreme stresses. They can be automated by electric motors and remote controls, according to the requirements of the project.
Sliding or Wagon Gate
TEMEC CPx
For installation in water intakes, distribution works, water treatment stations and others.
They can be adapted to different dimensions both in width and height, always associated with a civil construction work of easy execution.

Spillway gate
TEMEC CPVM
Useful for periodic changes in the flow demanded.
They can be opened downwards so that the water flow passes over them, preventing the entry of bottom solids.

Tilting Weir (Overshot) Gate
TEMEC CLVS
For installation in canals or rivers.
They can maintain a minimum level upstream, independently of the flow rate. As the flow increases, the units retract until they are fully retracted.

Distributors
TEMEC MOxx
For installation in canals or reservoir outlets.
They provide a practically constant flow rate, independent of upstream level fluctuations (within certain limits indicated in the tables).

Remote Controlled Radial Gate
TEMEC CST
For installation in canals or reservoir outlets.
They permit to regulate a through flow even in almost total submergence conditions. Low consumption manual or motorized drive and possibility of remote management.

Radial Gate
TEMEC CRAD
For installation in canals or reservoir outlets.
They admit high stresses and water loads, with a significant reduction of the energy required for their operation. Low friction stresses.
