Utilities play a vital role in the economic and social development of nations as they are essential services. In the next decade and ahead, the utilities industry will look vastly different due to factors such as climate change, regulation and competition, and population growth. The utilities industry is on the verge of a period of great change, our growing challenges of climate change and targets will impact all utilities, heralding new approaches to resilience and sustainability – particularly around urban areas with expectations for further significant population growth. At Dutco Tennant LLC we are continuously striving to provide convenience as well as innovative solutions for Utilities in the Middle East. We provide solutions in the Water, Electricity, Gas sectors along with our partner blue-chip principal companies present globally. We cover a range of turnkey solution from production to the transmission and the distribution networks for water, electricity and gas sector.Utilities play a vital role in the economic and social development of nations as they are essential services.

The means of slowing or stopping the driven equipment is provided by brake motors. The brake units which can be AC or DC are single disc type, mounted on the non-drive end of the motor. They are spring-applied electrically released units which provide fail-to-safe operating characteristics such that on interruption, or failure of the power supply, the brake will engage and arrest the load. With DC brakes, the brake coil is fed via a rectifier in the motor terminal box for frame sizes 63 to 180 and is automatically switched with the AC motor supply. On frame sizes 200 and above the brake is terminated in a separate terminal box. AC brakes are connected directly to the motor terminals. Both DC and AC brakes can, however, be separately energized from their own supply as in the case of inverter drives and/or cases where very fast brake operation is required. A friction disc which is keyed to the motor shaft is trapped between two metal plates. Among these two metal plates, one is fixed and the other moves axially under spring pressure. A magnet is energized when the motor supply is switched on compressing the spring and releasing the pressure on the plates and this allows the motor shaft to rotate. When the brake is de-energized or powered off, the springs re-apply the pressure to the metal plates acting on the friction disk.
