Nanjing Hjchem Equipment Co.,Ltd is a China-based manufacturer specializing in stainless steel clean in place tanks—the core vessels used to prepare, heat, and circulate cleaning media in a CIP (Clean-In-Place) loop. In food, beverage, dairy, brewery, and pharmaceutical plants, CIP tanks are not “support vessels.”
They directly influence cleaning repeatability, changeover speed, and hygiene risk because they determine how accurately your system can control temperature, chemical concentration, circulation stability, and step timing.
If you are sourcing CIP tanks from China, the most important decision is not only capacity. It’s whether the tank design supports stable heating, reliable chemical handling, hygienic circulation, and long-term maintainability in real production conditions.
What are stainless steel clean in place tanks
Stainless steel clean in place tanks are sanitary process tanks used in a CIP system to hold and condition cleaning media such as:
Hot water (rinse and thermal sanitation)
Caustic solution (alkaline wash for organic soils like proteins/sugars/fats)
Acid solution (removal of mineral scale and some inorganic fouling)
Optional recovery tanks (for reuse strategies and cost control)
These tanks feed a CIP pump and valve network to circulate cleaning liquids through tanks, pipelines, pumps, valves, and heat exchangers—without disassembly—inside a closed loop to reduce secondary contamination risk.

Reference specification table (standard CIP tank & pump models)
Below is a standard reference set often used in CIP stations (customization available).
| Model | CIP-0.5 | CIP-1 | CIP-2 | CIP-3 | CIP-4 |
|---|---|---|---|---|---|
| Acid Tank (L) | 500 | 1000 | 2000 | 3000 | 4000 |
| Caustic Tank (L) | 500 | 1000 | 2000 | 3000 | 4000 |
| Hot Water Tank (L) | 500 | 1000 | 2000 | 3000 | 4000 |
| Heating Method | Coil / Plate / Tubular / Steam Heating | Coil / Plate / Tubular / Steam Heating | Coil / Plate / Tubular / Steam Heating | Coil / Plate / Tubular / Steam Heating | Coil / Plate / Tubular / Steam Heating |
| CIP Pump Capacity | 10T | 10T | 20T | 20T | 30T |
| Pump Head (m) | 24 | 24 | 36 | 36 | 36 |
| Pump Power (kW) | 2.2 | 2.2 | 5.5 | 5.5 | 7.5 |
Note: The above specifications are standard references. Nanjing Hjchem Equipment Co.,Ltd can design and manufacture stainless steel CIP tanks and complete CIP systems based on your requirements.
Common CIP tank types and what each one does
| CIP Tank Type | Typical Use | What It Controls | Why It Matters |
|---|---|---|---|
| Hot Water Tank | Pre-rinse, final rinse, thermal sanitation | Temperature & rinse availability | Supports fast changeovers and sanitation capability |
| Caustic Tank | Alkaline wash (1%–2% typical in many beverage cycles) | Chemical concentration & heating | Key for removing organic soils consistently |
| Acid Tank | Scale removal / inorganic cleaning | Acid concentration | Helps manage mineral fouling and maintain heat exchanger efficiency |
| Recovery Tank (optional) | Collect and reuse media based on process | Reuse strategy | Reduces water/chemical consumption when properly engineered |
This is why people often select dual-tank or three-tank CIP stations: it improves step separation and cycle consistency.
Single-tank vs dual-tank vs three-tank CIP tank sets
| Configuration | Tank Set | Best Fit | Strengths | When to Upgrade |
|---|---|---|---|---|
| Single-Tank CIP | 1 tank (hot water or mixed solution) | Simple cleaning, low changeovers | Lowest footprint and cost | Need faster cycles or stronger repeatability |
| Dual-Tank CIP | Hot water + caustic (most common) | Most food & beverage lines | Better separation, faster programs | Routine acid step or scale issues |
| Three-Tank CIP | Hot water + caustic + acid | More demanding hygiene & scaling | Highest flexibility and control | Multi-zone plants needing parallel cleaning may add circuits |
If you are unsure, dual-tank is often the most economical long-term choice for frequent changeovers.

Frequently Asked Questions (FAQ)
1.What material is best for CIP tanks—304 or 316 stainless steel?
Many plants use 304 for general food applications, while 316 is preferred for higher corrosion resistance or more demanding chemical exposure.
2.What size CIP tank do I need?
Sizing depends on your circuit hold-up volume (tanks + piping + equipment), cleaning steps, and whether you run single, dual, or three-tank CIP.
3. What are CIP tanks used for?
They store and condition hot water, caustic, and acid solutions for circulation through process equipment during CIP cleaning cycles.
4. Can CIP tanks be heated by steam or electricity?
Yes. Nanjing Hjchem Equipment Co.,Ltd can provide steam or electric heating options, matched to your utilities and temperature targets.
5. What’s the difference between single-tank and dual-tank CIP systems?
Single-tank is simpler and smaller; dual-tank separates rinse/hot water and caustic, improving cycle speed and repeatability.
6.Do you supply complete CIP skids or only tanks?
We supply stainless steel CIP tanks and can also deliver complete CIP systems including pumps, valves, heating, and control cabinets.
