How the EcoMESH adiabatic pre-cooling system works

EcoMESH's unique design works by harnessing two naturally occurring cooling factors - water and shade.

In very simple terms, a fine water spray is directed onto a fitted mesh in intermittent short bursts and carefully regulated according to the ambient air temperature, meaning water use is kept to the minimum required for the unit to cool and function optimally.

The EcoMESH system effectively reduces air intake temperature with minimal water usage and has the added benefits of reducing energy consumption and minimising maintenance.

Ecomesh uses up to 79% less water than other wet systems and carries no risk to health since it does not require coarse water or still water reservoir.

How EcoMESH works

Environmentally sound choice

In short, the EcoMESH system saves water, energy, time and money making it an environmentally sound and cost effective choice for many businesses.

EcoMESH Design Features

EcoMESH Controller and sensor adapts and regulates according to the ambient air temperature, minimising energy and water use.
Our EcoMESH system can easily be adapted to fit any size or make.
EcoMESH is maintenance-free with no need for replacement nozzles of meshes. The system also reduces the maintenance frequency of your cooling unit.
Our uniquely designed fixing brackets make for precise and optimal positioning, with a light weight aluminium construction for ease of installation.
Multi-directional fine mist nozzle allows for even water distribution.
Our unique and durable mesh system will also prevent dirt, sand and general rubbish from entering your unit, protecting it from unnecessary breakdown and maintenance issues.

The origins of the EcoMESH technology

EcoMESH is based on proven principles that have been known to man for millennia.

The significant cooling achieved by water has been used throughout history to great effect. In the 2nd century a Chinese inventor called ‘Ding Huan’ of the ‘Han Dynasty’ invented the rotating fan - laying the groundwork for what we now know as Air conditioning.

The Ancient Romans were known to have circulated Aqueduct water through the walls of some houses to keep them cool. Across the Middle East wet hessian has been placed across windows in order to help cool the incoming breeze and for centuries water fountains have been used to moisten and cool the air, making courtyards cooler.

Medieval Persia had buildings with cisterns and used wind towers to cool the buildings during the hotter seasons. The cisterns were large open pools in the centre of courtyards and were used to collect rainwater. The wind towers had windows to catch the wind and force it down over the cistern effectively cooling the air.

A practical way to demonstrate the EcoMESH cooling process is to put water onto your face and turn it into the wind, your face immediately becomes cooler.

Frequently Asked Questions

Adiabatic pre-cooling is a method used in HVAC and refrigeration systems to reduce the temperature of incoming air using evaporative cooling. Water is sprayed into the airflow before it enters the condenser coil, which helps the system run more efficiently by reducing compressor workload.

EcoMESH is a patented dual-layer mesh and water spray system designed to improve the performance of air-cooled chillers, dry coolers, and refrigeration units. Unlike many adiabatic systems, EcoMESH is virtually maintenance-free, uses up to 85% less water, and does not rely on pads or filters that clog or degrade over time.

EcoMESH can be fitted to any air-cooled equipment, including chillers, dry coolers, refrigeration condensers, and VRF systems. It is ideal for applications such as data centres, supermarkets, cold storage, and manufacturing facilities.

Yes. EcoMESH can reduce HVAC and refrigeration energy usage by up to 44% during peak load, with typical annual energy savings between 15–25% depending on usage, climate, and equipment type.

Unlike traditional misting or wet pad systems, EcoMESH does not cause scale build-up or require frequent pad replacement. Its open mesh design and intelligent water control result in lower water consumption, no chemical treatment, and a longer service life.

EcoMESH uses a precision spray system that only activates when needed, reducing water consumption by up to 85% compared to other evaporative systems. This makes it suitable even in regions with water use restrictions.

No. EcoMESH is designed to run on standard potable water and does not require chemical dosing or additives, eliminating risks related to health, scale, and corrosion.

Yes. Because EcoMESH does not use recirculated water, has no standing water, and dries quickly after operation, we believe it poses minimal risk of Legionella or other bacterial hazards, making it ideal for hospitals, food facilities, and healthcare environments.

Not at present. EcoMESH currently operates as a standalone, self-controlled unit with its own intelligent controller. While BMS integration is planned for future development, the system can be operated independently of existing site controls.

EcoMESH often pays for itself within one cooling season, as little as 21 weeks, through energy savings alone. This rapid ROI is complemented by extended equipment lifespan and reduced maintenance costs.

EcoMESH systems are built to last. Independent third-party testing has validated a 25-year design life for the mesh components under hygrothermal exposure and a 50-year design life under wind load conditions. The system is made from durable materials such as UV-stabilised HDPE mesh, aluminium framework, and 316L stainless steel water headers.

EcoMESH systems come with a standard international warranty covering all parts for 12 months from the date of installation or 18 months from the date of shipment, whichever comes first. This ensures peace of mind and support for all new installations.

Yes. By reducing cooling energy demand by 15–30% annually, EcoMESH directly improves Power Usage Effectiveness (PUE) and supports sustainability targets.
No. EcoMESH cools external condenser air only and does not introduce moisture into indoor environments.
Yes. EcoMESH is widely used with CO₂ transcritical systems and improves the COP by lowering the gas cooler inlet temperature.
Yes. By lowering intake temperatures by up to 14°C in dry climates, EcoMESH significantly reduces the risk of overload and high-pressure shutdowns.

Yes. EcoMESH keeps water away from condenser coils. Unlike sprinklers or coil-wetting systems, it does not cause:

  • Mineral scaling
  • Corrosion
  • Fin damage

The water evaporates on the mesh, not on the coil.
