The Soft Drink Equipment Market
The global soft drink industry encompasses carbonated soft drinks (CSD), still beverages, juices, flavoured water, iced tea, sports drinks, and functional beverages. This diverse category requires equally diverse filling and packaging solutions, making the used equipment market for soft drink production one of the most varied and active.
Carbonated soft drinks remain the largest segment by volume, requiring specialised equipment for carbonation, counter-pressure filling, and pressure-resistant packaging. Still beverages and juices use simpler filling technology but may require thermal processing (pasteurisation or hot-fill) for shelf stability.
Used soft drink bottling lines frequently become available as major beverage companies consolidate production, upgrade to higher speeds, or shift between packaging formats (glass to PET, bottles to cans). This creates excellent opportunities for independent bottlers, contract packers, and emerging brands to acquire established production technology at accessible price points.
CSD Filling Technology and Carbonation Systems
Carbonation and Mixing Systems: Before filling, CSD products must be mixed and carbonated. Premix systems blend syrup and water before carbonation, while postmix systems add syrup after water is carbonated. Key manufacturers include KHS, Krones, Flottweg, and Alfa Laval.
When evaluating used mixing and carbonation equipment, verify CO2 injection efficiency, deaeration system performance, and brix (sugar concentration) control accuracy. The mixer-carbonator represents a critical quality control point.
Counter-Pressure Filling: CSD filling requires counter-pressure (isobaric) technology. The bottle or can is pressurised with CO2 before filling begins, preventing foaming and CO2 loss. Filling speeds for CSD are typically 10-15% lower than for still products due to the additional pre-pressurisation and post-fill snifting steps.
Hot-Fill Technology: An alternative for non-carbonated soft drinks. Products are heated to 85-92°C and filled hot, with the thermal energy providing pasteurisation. Hot-fill requires specially designed PET bottles with vacuum absorption panels. Used hot-fill lines from Krones, Sidel, and KHS are available for producers of juices, teas, and functional beverages.
Aseptic Cold-Fill: Premium technology for sensitive products. Provides ambient shelf stability without thermal degradation of flavours and vitamins. Used aseptic fillers (Sidel Predis, Krones Contipure, GEA) represent the highest-value segment of the used market.
Packaging Formats for Soft Drinks
Soft drink producers must choose between multiple packaging formats, each requiring different equipment configurations:
PET Bottles: The dominant format globally. Available in sizes from 200ml to 3 litres. PET CSD bottles require thicker walls and pressure-resistant designs compared to still water bottles. Used PET CSD lines typically include blow moulding, filling, capping, and labelling.
Aluminium Cans: The fastest-growing format. Standard sizes include 250ml slim, 330ml, and 500ml. Can CSD filling requires counter-pressure technology with seaming rather than capping. Used canning lines for CSD are in high demand.
Glass Bottles: Primarily used for premium and returnable-bottle markets. Glass CSD filling uses crown cap or screw cap closures. Returnable glass systems require additional equipment (washers, inspectors, decraters).
Carton and Pouch: Tetra Pak and similar formats for juice and still drinks. A niche segment in the used market with limited availability.
When planning a soft drink operation, consider multi-format capability. Some producers operate both PET and can lines to serve different market channels. Used equipment strategies can be particularly effective here, allowing investment in two formats for the price of one new line.
Secondary Processing and Quality Control
Pasteurisation: Tunnel pasteurisers are standard for CSD in glass and cans. Flash (plate) pasteurisers are used for hot-fill PET and inline treatment. Evaluate temperature zone accuracy, conveyor belt condition, and thermal treatment records.
Water Treatment: Soft drink production requires high-quality treated water. Reverse osmosis, UV treatment, and activated carbon filtration systems are essential. These auxiliary systems significantly impact final product quality and should be evaluated carefully.
Quality Lab Equipment: CO2 volume measurement, brix meters, pH monitoring, dissolved oxygen meters, and microbiological testing equipment. While not part of the filling line, these instruments are essential for production control.
Date Coding and Traceability: Laser coders, inkjet printers, and label printing systems for batch tracking and regulatory compliance.
Inspection Systems: Fill level detection (X-ray for cans, camera-based for PET), cap presence/torque verification, label inspection, and foreign object detection. HEUFT, Krones Checkmat, and Pressco are inspection equipment manufacturers whose products are widely available used.
Investment Strategy for Soft Drink Production
Starting or expanding a soft drink bottling operation with used equipment requires careful planning:
Production volume planning: Define your target annual volume and peak daily output. Size equipment at 120-130% of average requirement to accommodate seasonal peaks and preventive maintenance downtime.
Product range considerations: If bottling multiple products (cola, orange, lemon-lime, water), factor in changeover time between products. CIP (Clean-in-Place) cycles between flavours can take 30-60 minutes per changeover.
Typical investment ranges for used CSD lines:
- Small PET line (4,000-8,000 BPH): €200,000-€500,000
- Medium PET line (12,000-24,000 BPH): €500,000-€1,500,000
- Large PET/can line (36,000+ BPH): €1,500,000-€4,000,000+
Return on investment: Used CSD equipment typically delivers payback within 2-4 years for well-managed operations, compared to 5-8 years for new equipment. The lower initial capital requirement also reduces financial risk for new market entrants.

Frequently asked questions
What equipment do I need to start a soft drink bottling operation?
A minimum CSD line includes: water treatment, syrup preparation, mixing and carbonation, filling and capping, labelling, and secondary packaging. For PET, add blow moulding. Auxiliary systems include CIP, compressed air, and CO2 storage. Used equipment can cover all these requirements.
Can a used CSD filler handle both carbonated and still products?
Some modern fillers offer dual-mode operation, but most counter-pressure fillers are optimised for carbonated products. A dedicated gravity or electronic filler is preferred for still beverages. When buying used, specify your product range to ensure equipment compatibility.
What is the difference between hot-fill and aseptic cold-fill?
Hot-fill heats the product to 85-92°C before filling, using thermal energy for pasteurisation but requiring heat-resistant PET bottles. Aseptic cold-fill sterilises the container and product separately, filling at ambient temperature. Aseptic preserves taste and nutrients better but equipment costs are significantly higher.
