World-class super-silent generators

AST supplies open-type, weatherproof, sound attenuated, super silent, mobile specialised generator sets and ancillary products.

We design and manufacture a range of products for a wide variety of industries.

These custom built solutions are specially designed for the telecoms, film and entertainment, mining, agriculture, construction and leisure industries.

Our advanced technical expertise, knowledge and sound global technology alliances, enable us to provide a complete power solution.

our noise levels meet international levels and the set is built to European emission levels.

Mining and Industrial Use

For industrial companies with power-critical manufacturing processes, it is essential to keep operating, even when utility power is unavailable.

Examples include assembly lines, bottling and canning plants, plastics moulding operations and many others. AST understands that any break in the manufacturing process can result in entire batches being discarded and substantial financial losses.

The mining industry is highly dependent on a constant supply of electricity. Air conditioning and extraction of toxic fumes are essential to ensure a stable working environment underground. Without a reliable, constant power supply these systems can often fail to work resulting in a catastrophic event.

AST is able to assess each mine’s and industrial plant’s unique load requirements thus creating a specification to design and assemble a custom generator set that is able to put the power in your hands.

Factors to consider when choosing your power solution

  • What critical equipment will need to operate in the event of a power outage?
  • Will there be a need for remote monitoring?
  • Will the exhaust system require modification?
  • Will there be sensitivity of equipment i.e. the need for electronic governing?
  • Will there be need for sound attenuation?

All AST generator sets are designed and built in compliance with European Standards of Acceptable Noise and Emission levels.

Hybrid Generators

We offer an OPEX -reducing, integrated hybrid power solution. The idea is to reduce the running hours of the backup generator without compromising the required power supply needed to operate the BTS equipment. This is done by the co-operative functioning of a generator with a battery bank.

Benefits of the hybrid solution are:

  • Reduced generator fuel consumption,
  • Less frequent refuelling on sites,
  • Extension in frequencies of generator service intervals,
  • Greater output efficiencies of the generator
  • Reduced installation costs due to the integration of the hybrid solution,
  • Expensive components are housed within a robust 4mm thickness structure, with a heavy duty 3 – way locking mechanism and opened with a unique key which is not easily obtainable.
