Buying used coating equipment can save 40-60% compared to new, but only if you know what to inspect. This guide provides a systematic checklist so you avoid costly mistakes and get equipment that delivers real value.
Pre-Purchase Checklist
Spray Guns & Controllers
- Test high voltage output with a kV meter — should reach rated maximum
- Check electrode and nozzle wear — these are consumables but indicate usage history
- Inspect cable insulation for cracks or damage
- Verify controller functions — all settings should respond correctly
- Ask for maintenance history and total hours of operation
Powder Coating Booths
- Inspect interior walls for powder buildup, dents, or corrosion
- Check filter cartridge condition and differential pressure readings
- Test fan motor operation (vibration, noise, amperage draw)
- Verify cyclone separator integrity (if equipped)
- Check all grounding connections
Curing Ovens
- Check insulation condition — water damage or compression reduces efficiency
- Inspect burner assembly and heat exchanger for corrosion or scale
- Run a temperature uniformity survey — variations should be within ±10°C
- Check door seals, hinges, and locking mechanisms
- Inspect exhaust ductwork for blockages and corrosion
Conveyor Systems
- Inspect chain links, trolleys, and load bars for wear
- Check drive motor and gearbox condition
- Measure chain stretch — excessive stretch indicates heavy wear
- Test all safety switches and emergency stops
Red Flags to Watch For
- Seller cannot provide maintenance records or reason for selling
- Equipment has been exposed to weather or stored outdoors
- Electrical panels show signs of water damage or rodent activity
- Major structural modifications have been made without engineering documentation
- Price is significantly below market value (possible hidden defects)
Fair Pricing Guidelines
| Equipment Age | Condition | Expected Price (% of new) |
|---|
| 0-3 years | Excellent | 60-75% |
| 3-7 years | Good | 40-60% |
| 7-12 years | Fair | 25-40% |
| 12+ years | Worn but functional | 15-25% |
💡 Pro Tip: Budget an additional 15-25% of the purchase price for refurbishment, new wear parts, and reinstallation. A used oven at €30,000 may need €5,000-8,000 in new seals, burner service, and controls updates to perform reliably.
