Focusing On:
Window Automation Actuators
Our linear and chain actuators from UCS, Elero and TOPP have been used in window and skylight automation throughout Southern Africa in homes and offices.
Window automation and natural ventilation systems ensures energy saving, comfort and safety in buildings through integration in Building Management Systems. We offer customised solutions for electric actuators to access even the largest and heaviest windows.
Applications: Skylights & domes, top-hung windows, bottom-hung windows.
Products:
- TOPP Chain Actuator
- TOPP Linear Actuator
Smoke/Heat Extraction & Natural Ventilation
Smoke and heat extraction actuators are designed to rapidly extract smoke and hot gases in the event of a fire, reducing the risk of smoke inhalation and allowing for safe evacuation of building occupants. UCS's actuators comply with strict international safety regulations, including EN12101-2, and are CE-certified.
Natural ventilation actuators are designed to ensure optimal indoor air quality and reducing energy costs. Studies have shown that natural ventilation can reduce energy consumption in buildings by up to 40%, making it an environmentally-friendly and cost-effective option.

Linear Actuators for Solar Tracking
We provide linear actuators solutions for solar tracking to achieve accurate positioning to get optimal exposure of the sun.
Actuators for the solar industry enable controlled movement of solar panels which includes tilting of panels on a single or dual axis.
Our linear actuators have been specially developed for solar photovoltaic systems (Elevation and Azimuth). This combination significantly increases the efficiency of complex solar tracking systems and ensures a quicker amortisation of investment costs.

- Elero Insolsis linear actuators
Actuators for Medical Applications
Our linear actuators are used in hospital beds, which help in raising and lowering the of bed, or to reposition sections. Furthermore, actuators used in hospital lifts to control their movements and help move patients.
Recliners and dental chairs are often automated and powered by actuator systems.
Scanners: CT, MRI, and PT scanning instruments are used in hospitals, clinics, and palliative care units for examination and diagnosis purposes. These scanners are powered with linear actuators, which allow easy movement in any direction.
