The A-TORQ is an energy saving Adjustable Speed Coupling.
The A-TORQ will be used in motor driven systems that will run constantly at a reduced but fixed speed. 75% of all pump installations are at least 20% to large (Fraunhover Institute). Traditionally a choke valve is placed in the system and used to create artificial resistance to flow until the desired flow rate is achieved. This is a waste of energy. With an contact-free controllable magnetic coupling, the air gap between the magnet rotor and the inductor can be adjusted. As the air gap increases, the interaction of the magnetic fields is reduced, and the output speed of the pump or fan can be reduced to reduce the flow rate without requiring the choke valve wasting energy. With the A-TORQ energy savings up til -50% are possible.
Zytec has equipped the A-TORQ with a patented Spacer. The Spacer will give you the possibility to reduce the speed of the load mechanically when needed, without removing the coupling from the system. The A-TORQ can be easily adjusted after installation.
The installation is simple because there is no laser alignment required. The A-TORQ is suitable for motors with a capacity of 7,5 to 375 kW. Just like all Zytec couplings the A-TORQ also eliminates or significantly reduces problems associated with misalignment, vibrations and shock loading.

Specific Benefits of an A-TORQ
The specific advantage of an A-TORQ is the ability to reduce the speed of the load at a fixed level. With the A-TORQ energy savings up til -50% are possible. You choose a A-TORQ for the energetical benefits, but for your Total Cost of Ownership calculation you must also take the mechanical benefits savings into account.
The magnetic coupling is the solution for many known problems which we have come to accept through time. It is no longer necessary to carry out expensive and often recurring shaft alignments and incur high costs through the damage that is caused by misalignment.
Each coupling is calculated for the specifications of the system. To be able to select the correct coupling we need to collect basic motor, load and ambient condition information about the installation. We also identify the objective of the installation of the Zytec coupling – torque limiting, energy saving, maintenance reduction, etc. By acquiring this information we can ensure that your system functions as efficiently and reliably as possible.
Purchase, maintenance, repairs, energy wastage and the costs of (an unexpected) downtime are all part of the Cost of Ownership of your systems. The installation of the induction coupling results in reduced wear to both the motor and the load side: shock loads are dampened; damage from misalignment is eliminated; cold start-up problems are reduced/eliminated with torque ramping up from start; etc. all of which result in lower maintenance costs. The preventative maintenance schedule can be amended. The coupling itself has a rugged design and needs little maintenance. This all results in longer operational periods, certainly through the reduction of unplanned stoppages for repairs.
Using Zytec A-TORQ results in lower Total Cost of Ownership of your total installation. You will make immediate savings on the hidden costs. The visible costs will often be recovered within industries expected pay-back time. Each coupling is tailored according to your system specifications. The Zytec Certified Partners will be pleased to help you in selecting the correct coupling for your installation and calculating the total Cost of Ownership and the payback period.
