Complete System
Not Just Equipment
Most powder coating investments require 18-24 months to break even, but what if you could reduce that to 12-15 months? Ketu designs complete in-house electrostatic powder coating production lines that integrate design, manufacturing, installation, and lifelong support—ensuring your line runs efficiently from day one.

Pre-Treatment: The Foundation of Quality
Surface cleanliness directly determines powder adhesion strength and coating durability. Our multi-stage system ensures ISO 8501-1 Sa 2.5 standard compliance.
Ketu Multi-Stage Process:
- → High-pressure water washing (50-100 bar) to remove mill scale and debris
- → Spray degreasing and multi-level rinsing
- → Phosphate/manganese film formation (15-25 μm)
- → Chromate-free or chromate passivation per customer requirements
Spray Booth: Precision Electrostatic Technology
Static spray guns (60-90 kV) increase powder adhesion to 95%+, while our multi-gun configuration adapts to any product shape from 2cm to 5m wide.
Ketu Spray System Features:
- → 1-8 gun configurations (standard, Faraday cage adapted)
- → Adjustable gun angles (±45°) and heights (1.2–2.5m products)
- → Optional preheating booth (80–150°C) for improved flow-out
- → Millisecond-level timing control for precise coating thickness
Curing: Dual Technology Options
Choose between electric precision (±5°C) or gas efficiency (30-40% energy savings). Both achieve superior film hardness and adhesion.
Electric Curing: Perfect for precision-critical products (±5°C tolerance, CV <2°C across oven). cURL Too many subrequests by single Worker invocation.

Environmental Compliance: Zero Discharge
Complete VOC, waste powder, and wastewater treatment ensures compliance with US EPA, EU RoHS, and Chinese GB/T standards without operational burden.
VOC Management Options:
- → Activated Carbon Adsorption: Low-cost, good for <100 mg/m³ VOC (removal efficiency 80-90%)
- → Direct Incineration: 99%+ efficiency, heat recovery for oven preheating
- → Regenerative Thermal Oxidizer (RTO): 99.5%+ efficiency, 60-70% energy savings vs. direct burn
Wastewater Treatment: Multi-stage precipitation + filtration achieves GB 8978 Class I discharge standards (total phosphorus <0.5 mg/L, total nitrogen <15 mg/L).
