Lithium bromide (LiBr) absorption chillers are steam- or hot-water-driven — used in CCHP plants, hospitals, textile and chemical factories and anywhere waste heat drives cooling. Because the “compressor” is a thermal cycle, fouled absorber and condenser tubes translate directly into higher steam consumption per RT. An automatic tube cleaning system for lithium bromide chillers keeps those tubes clean while the machine runs.
Why Absorption Chillers Are Sensitive to Fouling
- Thermally driven cycle: there is no mechanical compressor to compensate — fouling raises condensing pressure and the machine simply consumes more steam for less cooling.
- Two heat exchangers, twice the risk: the absorber and condenser both rely on tube-side heat transfer; fouling on either degrades capacity and COP.
- Crystallization risk: poor heat rejection pushes the solution toward crystallization, one of the most expensive LiBr failure modes.
- Long running hours: hospital and industrial absorption plants run continuously — shutdown cleaning windows are rare.
Online Tube Cleaning for Absorption Cooling
HyApexFlow supplies an online tube cleaning system for absorption cooling: sponge balls circulate through the absorber and condenser tube bundles on a programmed cycle, scrubbing biofilm and scale as they pass. The chiller keeps running — the cleaning system works on the water side without interrupting the refrigeration cycle.
| Parameter | Typical LiBr fit |
|---|---|
| Chiller size | 100–1,500+ RT absorption units |
| Heat source | Steam / hot water / direct-fired |
| Cleaning mode | Continuous online ball recirculation |
| Typical steam saving | 5–15%; more where fouling was heavy |
| Shutdown for cleaning | None during operation |
CCHP, Hospitals and Industrial Plants
For ATCS for industrial absorption cooling plants, the economics are straightforward: every percentage point of tube cleanliness is steam (fuel) the boiler does not have to produce. Hospitals gain the added benefit of no disruption to critical cooling, and CCHP operators protect the waste-heat utilization rate that justifies the trigeneration investment.
Retrofit Existing Absorption Chillers
Existing LiBr machines accept a retrofit cleaning system without tube modification — see the ATCS retrofit installation guide.

Documented SEA Deployments & Absorption-Duty Specs
HyApexFlow supplies online tube cleaning for absorption chillers across Southeast Asia, including an Indonesia beverage plant running a lithium-bromide absorption chiller (see the Documented Case Studies page). For absorption and brine duty we specify temperature-resistant cleaning balls and corrosion-compatible wetted materials — SS316L or titanium — on the same single industrial duty pump used across the ATCS range. Cleaning runs online, so absorption plants avoid shutdown and the fouling-driven steam penalty.

Frequently Asked Questions
How much steam can an absorption chiller save with ATCS?
Typically 5–15% steam consumption reduction, and more where fouling was severe, because the absorber and condenser transfer heat closer to design conditions.
Does cleaning require stopping the absorption chiller?
No. The ball system works on the cooling-water side while the machine operates, so hospital and industrial loads are not interrupted.
Can ATCS reduce crystallization risk in LiBr chillers?
Indirectly, yes — by keeping heat rejection efficient, the solution stays within its concentration/temperature operating envelope, reducing the conditions that lead to crystallization.
Frequently Asked Questions
Can ATCS clean lithium-bromide chillers?
Yes. HyApexFlow provides a dedicated LiBr configuration that cleans both the absorber and condenser tube circuits.
What ball temperature rating is used for LiBr?
High-temperature EPDM balls rated for continuous operation in LiBr duty.
Where has HyApexFlow deployed LiBr ATCS?
Across Southeast Asia, including documented lithium-bromide installations.
