Defuse the Capex Timebomb. Meet the 25-Year Data Centre Chiller.
By pairing Cloudburst’s Smartmist precooling with Promek AMC coating, we extend chiller lifespans to 25 years, cut energy use by up to 12%, and protect your uptime on the hottest days of summer.
High risks and rising costs
Air-cooled chillers are the data centre standard because they avoid the installation cost, water treatment and Legionella risk of cooling towers. But running 100% uptime on air-cooled plant comes with a ticking clock.
The Capex Timebomb
Most chillers last just 15 to 20 years. At up to $500,000 per chiller, a facility with 60 to 80 units faces a staggering replacement cycle.
The Coil Trap
Mid-life degradation and corrosion force coil replacements. A single 1500 kW chiller can have up to 20 coils, and replacing just one costs around $30,000.
The Peak-Summer Threat
Chillers typically run at 60% of Effective Full Load Current (EFLC). On high-ambient days demand spikes to 100%, and scaled or corroded coils push operating pressures towards a trip when you can least afford it.
Energy reduction that misting systems can deliver on peak summer days.
Efficiency today, damage tomorrow
To solve the summer peak problem, many facilities turn to misting. But raw misting destroys the chiller from the outside in, within just a few years:
Precooling efficiency meets total corrosion protection
Promek delivers the world’s first unified solution: leading USA precooling technology paired with our advanced Australian-engineered thermal coating.
Smartmist by Cloudburst
The Power- Instant precooling. Drops ambient air temperature before it hits the coils.
- Proven savings. Reduces overall chiller energy consumption by up to 12%.
- Trip prevention. Relieves operating pressure during peak ambient conditions.
Promek AMC Coating
The Shield- Thin-film protection. Applied at just 12–16 microns, so coils keep transferring heat as designed.
- Corrosion & scale immunity. Formulated to stop the fin corrosion and calcium scaling caused by water evaporation.
- Efficiency boost. A baseline 2% saving on new coils and 8–12% recovery on older, degraded coils.
Smartmist in action




Together they unlock a 25-year chiller lifespan, a global first in data centre infrastructure.

Next-generation evaporative cooling from Cloudburst, engineered to keep critical equipment available through the hottest months of the year.

Built on the psychrometric chart
The psychrometric chart is the scientific foundation for analysing the thermodynamic properties of air, including how much moisture it can absorb. Smartmist uses this principle to add exactly the right amount of ultra-fine mist to cool the incoming air.
- Protects availability in summer by improving the chiller’s Delta T.
- Increases efficiency and capacity in high-temperature conditions.
- Restores design conditions by bringing air temperature and density closer to what your chillers were designed for.

Sensors, control and an evaporation zone
Atmospheric sensors measure the outside conditions, and these readings set how much high-pressure mist is dosed through precision nozzles at strategic air inlet points.
The system PLC calculates the optimal amount of mist to saturate the air to the desired level, while the adjustable nozzle matrix is positioned for relative humidity conditions. The mist evaporates in the zone ahead of the coils, so the chillers receive colder, denser air.
A proprietary water treatment system combines multi-stage filtration with Solavite physical treatment, so potable town water can be used without demineralisation.
Sense
Atmospheric sensors continuously read ambient temperature and relative humidity.
Calculate
The system PLC works out the exact amount of mist needed to saturate the air to the target level.
Mist
1200 PSI pumps feed precision nozzles at the coil air inlets, with nozzle positions matched to humidity conditions.
Stage & Monitor
Four operating stages switch on and off to maximise efficiency and minimise water use, with remote monitoring over Ethernet/IP.
Typical site services
- WaterFresh water, 1″ feed, min. 30 PSI at 2.8 gpm
- Power5 kW supply (3.5 kW installed load), single or three phase
- ControlsEthernet/IP remote monitoring & operation
Engineered for critical plant
- Solavite water treatment. Five-stage physical filtration allows potable town water to be used without demineralisation.
- Low water consumption. Staged operation delivers only the mist the conditions call for.
- 100% automated. Runs itself from sensor data, with pressures, temperatures, humidity and status reported remotely.
- Non-invasive, modular install. Fits around your existing plant, with the mechanical layout customised to each site.
Minimum shutdown. Maximum lifecycle.
Upgrading your infrastructure shouldn’t compromise uptime. Our specialised application process is engineered for the zero-downtime demands of data centres.
Minimal Shutdown Time
Promek AMC application and Smartmist installation are executed with precision, chiller by chiller, causing minimal disruption to daily operations.
EFLC Optimisation
Lower thermal stress all year round reduces your annual Effective Full Load Current, dropping power bills and extending mechanical wear-life to 25 years.
Proven Track Record
This isn’t experimental. 40 major 1500 kW data centre chillers are already coated and operating at peak efficiency right here in Sydney.
Planned Maintenance
Annual maintenance of the misting system is required, and regular coil flushing keeps coils clean and performing as designed.
Water Analysis on Every Project
Town water supply is analysed on each project, giving you complete control of water treatment from day one. Solavite filtration means no demineralisation plant is needed.


The numbers speak for themselves
Every year added to a chiller’s life defers a six-figure replacement. Across a full fleet, that is tens of millions in avoided capital spend.
| Metric | Standard | With Promek |
|---|---|---|
| Chiller lifespan | 15–20 years | 25 years |
| Energy consumption | Baseline | Up to 12% lower |
| Coil performance | Degrading | 8–12% regained |
| Coil replacement | $30k per coil | Mid-life replacements avoided |
Chiller lifespan
Example: 60–80 chillers × up to $500,000 each is a $30M–$40M replacement cycle, deferred by 5 to 10 years.
