Who we work with

OEMs & Device Manufacturers

You are designing a product and need a drive that fits the envelope, the duty cycle and the unit cost. We size the motor, gearbox, encoder and controller with the manufacturer, from prototype through to series build.

System Integrators & Installers

You are building a machine, a control panel or an installation to a fixed specification. We match drives, actuators and controllers to the mechanism you have already designed, and to the standard it has to meet.

Infrastructure & Facilities Operators

You run gates, barriers, ventilation or access points that cannot fail. We specify hardware rated for the cycle count and the conditions, and we handle the warranty claim locally.

Product Range

Standard catalogue items, or configured to your specification at the factory.

Electric motors

Brushed DC, brushless DC, AC and AC/DC motors from Ø 4 mm upwards, with power from 0.3 W to 900 W. Plus complete configured-to-order drive systems.

Gearheads and gearboxes

Planetary, spur, worm, spindle and right-angle gearboxes matched to the motor at the factory.

Controllers, encoders and motion control

Speed controllers, positioning controllers, programmable motion controllers and magnetic, optical and inductive encoders.

Actuators

Linear, chain, rack and spindle actuators from 90 N to 100 000 N. Window actuators for smoke and heat exhaust ventilation. Industrial heavy-dtuy linear actuators.

Electric drives

Tubular motors for roller shutters, awnings and screens, venetian blind drives, rolling door drives and lifting columns. Plus automotive electric motors.

Access control systems

Vehicle barriers, toll booms, AFC fare gates, full-height turnstiles, ticketing terminals, pedestrian gates, access control for public transport, airport security gates and building access control.

How we work

From first enquiry to ongoing supply. Four steps, and the first one is the one that matters.

Step 01
Consult

You tell us what has to move. We ask about load, speed, torque, duty cycle, operating environment, control method, safety standards and expected lifecycle before we recommend anything.

Step 02
Specify

We recommend the best solution for your application, matching the motor, gearbox, encoder, controller and protection class to your exact requirements. Where customisation is needed, we work with our manufacturing partners to configure the ideal solution.

Step 03
Supply

The order goes to the factory as a standard catalogue item or as a configured-to-order build. We coordinate with our partners until final delivery.

Step 04
Support

Spare parts, technical support and warranty handling. DNH opens the claim, routes it, and follows it through, so you are not dealing with an offshore returns desk on your own.

Our partners

Authorised distributor and technical partner for leading motion technology brands in Southern Africa.

Trusted by industry leaders

DNH has specified and supplied these components from Johannesburg since 1990. We supplied the access control gate hardware for South Africa's rapid rail network, and for national toll road concessions. Those are environments where a failure is expensive and the downtime is public. That is the standard we specify to. The same components run in mine ventilation control panels, skylight and roof window installations, switchgear assemblies, powered wheelchairs and last-mile electric vehicles across Southern Africa.

Gautrain

Sector: Rapid rail transit

DNH supplied access control gate hardware for the Gautrain network, where fare gates run continuous high-cycle duty through the morning and evening peaks while stopping a second traveller tailgating through on one fare.

Ventrite

Sector: Mine ventilation

Ventrite builds mine ventilation control panels for South African mining operations using DNH-supplied UCS rack systems and elero actuators.

Four Seasons Roof Windows, Skylights Cape Town, Tony Sandell Roof Windows

Sector: Skylight and roof window automation

DNH-supplied Topp and UCS actuators for skylight and roof window installations across South Africa. Every skylight differs in size and weight, so the actuator is matched to the sash, the stroke and the opening force.

CE Mobility

Sector: Powered mobility

CE Mobility specifies Parvalux PM50 motors for the electric wheelchairs it supplies to South African mobility users.

ACTOM

Sector: High voltage switchgear

ACTOM specifies Parvalux SD1 series motors in configurations matched to its industrial switchgear assemblies.

Mellow Cabs

Sector: Last-mile urban EVs

Mellow Cabs uses SEG electric drive motors on its last-mile urban EV platforms, where constant stop-start cycling in dense city traffic makes drive efficiency a direct input to range and fleet earnings.
