Our two disciplines

Biogas · the gas-to-energy chain

From the ground to the flame.

Custom engineered systems for gas flaring, membrane gas storage, gas conditioning, upgrading, moisture removal and delivery of combustible gases to the point of use. One accountable supplier for the whole chain.

  • Flaring at >99.99%

    Hofstetter HTF, MTF and emergency flares, fixed, containerised or mobile, with CDM-certified measurement.

  • Storage, cooling and cleaning

    Agrotel CenoTec membrane holders, Aprovis FriCon chillers and biological or carbon desulphurisation.

  • Analysis and CDM compliance

    Gas composition surveys, PDD-based monitoring, SCADA and monthly emission-reduction calculations.

Solar · generation and storage

Engineered like a power plant. Sized like a home.

Complete solar energy and battery backup solutions with client education and training, from 6.6 kWp family homes to 21 kWp three-phase farmsteads, all monitored remotely by the engineers who built them.

  • Smart auxiliary loads

    Geysers and pumps run on surplus PV while the grid is down, preserving the battery for what matters.

  • Remote monitoring

    Every system reports back to Renew. We see faults first and push optimisations remotely.

  • Training and documentation

    Single-line diagrams and customised handover documents make future changes simple.

03 · Temperature measurement

Thermocouples, made locally with traceable accuracy.

Types J, K, R, S, T, N and E thermocouples plus PT100 RTDs, cables, plugs and thermowells, manufactured in South Africa with SANAS-traceable certification available.

Selection of industrial thermocouples and temperature probes

Technology partners

World-class equipment, supported locally.
