How it works

Monitored machines — interactive

Compressor, mainline pump, drive — machines whose downtime is measured in millions. Measurement points on the models: vibration on bearings, current from CTs in the cabinet.

Results in numbers

  • +1.5–2% yield of target fractions (diesel, kerosene) with APC on primary processing
  • +2% feed throughput — with no capital investment
  • −3% specific energy use of units when heat loops are optimized
  • We detect pump and compressor faults 2–6 months before failure

Industry benchmarks; your actual results follow a site assessment at your operation.

Proven cases in oil & gas: raising automation at the Yuzhno-Balykskaya gas-processing station (SiburTyumenGaz) — remote control that removes the human-error factor, 2019; data acquisition and transmission systems plus MES for seven oil depots of Gazpromneft-Terminal, 2020–2023.

Adjacent process stage — Chemistry: polymerization, extrusion, pelletizing, reactor-and-column operations.

How to buy

Three commercial models

From outright purchase to a service model where you pay out of verified savings.

CAPEX — purchase

You own the hardware and software — the full effect is yours. Transparent and familiar; for critical infrastructure it is the only option.

MaaS — subscription

Monitoring-as-a-Service: 36 months, a monthly base fee plus a share of the verified effect. The performance risk is ours — no effect, nothing beyond the base.

ESCO — energy performance contract

Energy-saving measures with no capital outlay on your side: we invest, repayment comes out of verified savings.
