Automatic Tube Cleaning System for Chillers: Specifications and Selection
An automatic tube cleaning system for chillers is a capital investment with a measurable payback. This page is the buyer’s reference: components, performance specs, the WB-vs-TB6 choice, and a selection checklist you can take to bid.
What Is an Automatic Tube Cleaning System?
It is an ATCS: ball collectors, launch/recovery valves, and a microcomputer controller that keeps condenser tubes clean online. It converts a chiller from “clean until fouled” to “clean by default.”
Core Components
Cleaning balls (nano-silicone, 0–200°C, 0.1 mm ID match); a ball collector/recovery strainer; a launch valve (dual-channel on TB6); a microcomputer controller (25 W for WB, ≤0.2 kW for TB6) with RS485; and a 1.5 mm inlet strainer plus differential-pressure protection.
Key Performance Specs
Energy recovery: 15–35% of fouling-related penalty (site-dependent). Approach-temperature rise held to ≤ 0.3±0.1°C. Added water resistance ≤ 0.5 m head. DN coverage DN100–DN500 (TB6), customizable. Ball life far exceeds the 500–1000 cycles where rubber balls fail.
WB vs TB6: Which to Choose
WB front-end: integrated at the factory with the host chiller, no external power distribution, best for new units and adds only ~30–40 cm axially. TB6 pipe-integrated: field-retrofit, ~2 m² plant-room footprint, needs three-phase power, covers the full DN100–DN500 range on existing piping.
Selection Checklist
1) Condenser tube ID (for ball size). 2) Unit DN class (DN100–DN500). 3) Chiller type (screw/centrifugal/mag/VFD) and OEM. 4) New-build (WB) vs retrofit (TB6). 5) Current approach temperature (baseline for savings estimate).
ROI in Practice
For a representative 1260 RT plant, annual operating cost fell from ~1,085,994 RMB to ~1,006,434 RMB after installation — about 79,560 RMB/year saved. Payback is typically driven by how severe pre-installation fouling was.
FAQ
How do I choose an ATCS for my chiller?
Match the ball size to the condenser tube ID (0.1 mm precision) and pick WB for new units or TB6 for retrofit, then confirm DN class (DN100–DN500) and OEM compatibility.
What DN range is covered?
The TB6 pipe-integrated series covers DN100 through DN500 and is customizable; the WB type is sized to the host chiller’s condenser.
What is the typical payback period?
Payback scales with pre-installation fouling severity. In a documented 1260 RT case the system saved ~79,560 RMB/year, which against installed cost is a multi-year, often sub-3-year, recovery.
