Save Energy today,
for a greener tomorrow

From just a single device you can expect up to 40% energy saving on your air-conditioning
and up to 30% on your refrigeration without your cooling output being affected.

Saving on Energy

Energy Saver

Delivered by Tutum Energy


In most air-conditioning applications, a lot of energy is wasted because the unit’s compressor (the main running cost component) runs much longer than is needed. Using a patented process, the advanced COOLNOMIX® control device reduces the run-time of the cooling system compressor, therefore, reducing electricity consumption even in the most demanding high and humid environments. This results in less energy output required that saves on emissions and money.

How can COOLNOMIX® deliver such large energy savings?

COOLNOMIX® optimizes the operational run-time of the cooling system compressor. Since the compressor accounts for ~95% of the power consumption of a cooling system, optimizing its runtime can deliver very large savings. COOLNOMIX® employs two temperature sensors – one to regulate the room/space temperature delivered, the other to measure the cold-supply air temperature. The latter is used to determine when the hydraulic work of the compressor is completed – when the refrigerant gas is ully compressed. Once this reservoir of cold-supply has been created, COOLNOMIX® stops (non-inverter) or slows down (inverter) the compressor until further hydraulic work is needed. It is the compressor off-time or slowed-time that delivers the astonishing energy savings.

Doesn't the increased stopstart of the compressor introduced by COOLNOMIX® damage the compressor?

The internationally patented process Optimized Refrigerant Supply (ORS®) which is incorporated in COOLNOMIX® has specific protection included within its function. This includes protection against too frequent stop-start of the compressor and assurance that every re-start is always a soft-start – the re-start of the compressor is never under load since the suction and discharge pressures are guaranteed to be in equilibrium. As a result there is no adverse effect on the operational life of the compressor of the cooling system.

What about temperature stability when using COOLNOMIX®?

ORS® incorporates a priority on delivering the required room/space temperature – energy savings will be sacrificed in order to ensure the room/space temperature is achieved. COOLNOMIX® typically improves temperature control in air-conditioning and refrigeration systems. In contrast with most installations having room/space temperature variations of 1-2°C (1.8-3.6°F), our dual temperature sensor approach commonly limits room temperature variations to 50% of that experienced without COOLNOMIX®.

Isn't the warranty of the cooling system invalidated by retrofitting COOLNOMIX®?

COOLNOMIX® acts as an Intelligent thermostat, sending only a thermostatic request for the compressor to run or to stop it (non-inverter) or slow it (inverter). The sometimes complex system control boards found in cooling systems suffer no interference from fitting COOLNOMIX®. There is also now an economic factor to consider: for the ~20% of cooling systems still under warranty, what was a no-cost warranty now carries a penalty of unnecessary system operation costs of 30%+ if COOLNOMIX® is not fitted!

On what cooling systems can COOLNOMIX® be deployed?

COOLNOMIX® delivers energy savings on airconditioners of any size and any kind, including:

  • Commercial split-type air-conditioners (e.g. wall
    mounted or ceiling cassettes)
  • package based and double expansion (DX) units up to the largest sizes available
    up to the largest sizes available
  • ducted AC’s with AHU’s
  • inverter based (VRV and VRF) AC’s On refrigerators, COOLNOMIX® can be deployed to deliver energy savings on:
