ACCS™

Chiller Automatic
Condenser Cleaning

Elastomer balls are continuously recirculated through condenser tubes while the chiller keeps running at full load — restoring design-point heat transfer efficiency with zero chemicals and zero production downtime.

SBR™

Non-Chemical
Water Treatment

Scale and Bio-Removal precipitates scale-forming salts out in a reaction chamber instead of on your heat exchangers — running cooling towers at 2–3x higher cycles of concentration with zero chemical dosing.

COLTCS

Power Plant Condenser
Onload Tube Cleaning

Sponge rubber balls are injected into the condenser system and recovered by a custom-designed ball trap for reuse — holding back-pressure at design point and protecting the MW output fouling would otherwise steal from the grid.

Water conservation first

Recover and recycle cooling water that conventional systems waste. Reduces water consumption by 40–70% in optimised installations.

Energy efficiency at scale

Lower the energy footprint of cooling towers, chillers, and condensers — reducing operating costs and scope 1 & 2 emissions simultaneously.

ESG-ready sustainability reporting

Every litre of water and unit of energy saved is measured and quantified in real time — verified figures you can carry straight into your ESG disclosures, green building certifications, and board reporting.

Designed for reliability

Built for continuous industrial operation — low maintenance requirements, long service intervals, consistent performance in demanding environments.

Scalable across capacities

From smaller commercial installations to utility-scale power plants — the same proven platform, right-sized for your operation.

Expert installation & support

Turnkey installation by certified engineers, with minimal disruption to operations and global after-sales support.

Real results. Verified outcomes.

Numbers our clients trust — outcomes from live deployments across industries and regions.

Power Generation

Large power plants keep condensers online, add MW to the grid

Multiple large power plants now operate their condensers continuously without shutdowns using COLTCS — resulting in improved operational efficiency and more MW delivered to the grid.

Pharmaceutical

Leading Indian pharma manufacturers standardise on CET Enviro

Major pharmaceutical companies in India have installed CET Enviro technologies since 2016, resulting in significant cost savings through improved energy efficiency across their GMP-compliant cooling systems.

Commercial Hospitality

Luxury hotel chain eliminates chemical dosing, cuts emissions

A luxury hotel chain adopted SBR™ non-chemical water treatment to remove chemical dosing from its cooling towers — helping the group achieve its environmental goals and significantly reduce its carbon emissions.

We don't just build cooling systems. We conserve water.

From power generation and pharmaceutical manufacturing to commercial real estate, healthcare, and heavy industry — CET Enviro's systems protect water and deliver measurable cost savings everywhere cooling reliability matters.
