KEEP CONDENSER TUBES CLEAN - CONTINUOUSLY
EQOBRUSH is an Automatic Tube Cleaning system for water-cooled chillers and shell-and-tube condensers, designed to prevent fouling, stabilize performance, and reduce unnecessary energy consumption through effective Automatic Tube Cleaning practices.
- Zero Downtime Operation
- Prevents Fouling & Scale Build-up
- Stabilizes Condenser Performance
Industrial plants, commercial HVAC, and data center cooling systems apply Automatic Tube Cleaning technology to maximize longevity of their equipment.
Field Evidence:
Clean Tubes After 2 Years of Uninterrupted Operation
This inspection video shows a chiller after two years of continuous operation with EQOBRUSH Automatic Tube Cleaning System. While the end plate shows normal wear, the internal tubes remain clean — without manual or chemical cleaning.
The benefits of an Automatic Tube Cleaning system cannot be overstated, as it significantly reduces maintenance costs.
- No shutdown cleaning
- No chemicals
- No performance degradation
FOULING:
You don’t see it – But you pay for it
Investing in Automatic Tube Cleaning technology leads to substantial savings over time.
Even a thin fouling layer has a measurable impact on performance.
A deposit of just 0.3 mm can increase energy consumption by up to 10%.
As fouling builds up, condenser temperatures rise — reducing system efficiency and increasing compressor load.
The Automatic Tube Cleaning process effectively combats fouling.
- +3–4% efficiency loss per °C increase in condenser temperature
- Typical real-world losses: 5–10% energy penalty
- Increased compressor load and wear, and tube pitting
- Reduced cooling capacity under peak demand

How It Works: Automatic Tube Brushing During Operation
Automatic Tube Cleaning helps maintain optimal thermal performance.
EQOBRUSH keeps condenser tubes clean at all times using mechanical brushing — fully automatic and without interrupting operation.
No shutdowns. No chemicals. No performance drift.
The system operates in a controlled brushing cycle:
- Brushes are held inside each condenser tube
- At set intervals, flow reversal drives the brushes through the tubes
- Deposits are mechanically removed from the tube walls
- The system returns to normal operation — fully clean, every cycle
BRUSHES:
Controlled Mechanical Cleaning You Can Rely On
Fouling builds continuously — every operating hour.
EQOBRUSH uses controlled mechanical brushing to actively remove deposits from every tube on every cycle.
With a typical service life of 3–5 years, brush elements require minimal maintenance and contribute to a low total cost of ownership.
- Active mechanical cleaning — not dependent on flow conditions
- Effective against biofilm, scaling, and fouling layers
- Consistent performance, not gradual degradation
- Every tube is cleaned — on every cleaning cycle
- No chemical dosing or manual cleaning required
Implementing Automatic Tube Cleaning will decrease energy costs significantly.
THE HIDDEN COST OF PERIODIC CLEANING
Periodic performance assessments can reveal the potential benefits of Automatic Tube Cleaning in your Chillers and Shell and Tube Heat Exchangers.
The green line represents a clean system operating at optimal efficiency, with automatic tube cleaning installed.
In systems with periodic cleaning, performance gradually declines between cleaning cycles — as shown by the red dotted line.
The red solid line represents the average energy consumption over time.
The gap between the green and red line represents continuous energy loss, every operating hour.
Energy losses from fouling are often significant enough to achieve payback in less than one year.
This does not yet include:
– Avoided downtime and cleaning cost
– Extended equipment lifetime (compressor wear and tube pitting)
