Technology & AI engine

Capture a stable low-grade source, upgrade it with heat pumps under machine-learning control, deliver usable heat. Two delivery paths share one architecture.

Industrial pipeline

  1. 01

    Capture

    Extract waste heat from refinery liquid effluent, process cooling loops and cooling towers. Sensors monitor flow rate and temperature continuously.

  2. 02

    Upgrade

    AI-governed water-to-water and air-to-water heat pumps amplify temperature using minimal electricity. Machine learning ingests real-time flow, temperature and steam demand to optimise compressor speeds — without disrupting primary operations.

  3. 03

    Industrial supply

    Deliver pre-heated boiler feedwater directly to refinery boilers, cutting natural gas combustion.

  4. 04

    Facility supply

    Deliver space heating and domestic hot water to administrative complexes and district heating networks.

The defensible layer

The heat pumps are commodity hardware. The control policy and the digital twin are not. Optimising compressor speed against live process demand without touching the primary process is the reason a plant manager lets us near it at all.

Urban transit & municipal

Urban pipeline

Simpler and cheaper: modular air-source heat pumps at existing ventilation nodes. Capture happens before the air escapes the shaft, so nothing about metro operation changes.

The same loop cools the tunnels — relief for the 82 energy-intensive ventilators currently in service.

Why it beats a standard heat pump

A conventional air-source heat pump pulls from freezing winter air: high electricity demand, low efficiency, high cost. We pull from a stable warm source year-round.

It earns its keep in both seasons

The answer to “this is only a winter product”.

Industrial & downstream

Boiler feedwater pre-heating and facility space heating — direct gas OPEX reduction.

Urban transit & municipal

Recovers heat efficiently from stable tunnel air.

Scientific base

Thermodynamic modelling in Aspen HYSYS, with field measurements and telemetry research feeding an AI digital twin. Validating that twin is the stated purpose of the pilot.
