Building a reliable evaporator for an ice machine combines engineering precision with smart material choices. Below, we walk you through our streamlined process—designed to deliver high cooling efficiency, long service life, and worry-free operation for your commercial or industrial ice makers.

1. Tailored Design & Material Selection

Every ice application is unique—soft-serve kiosks, seafood storage, or large-scale food processing. We start by understanding your cooling load, ice production rate, and space constraints. Then we select stainless steel or copper-alloy tubing that offers excellent thermal conductivity, corrosion resistance, and food-safe performance.

  • Tube diameter & wall thickness tuned to your pressure and thermal requirements.
  • Fin geometry optimizes heat transfer and airflow in your machine’s evaporator coil.

2. Precision Tube Bending & Coil Winding

Smooth refrigerant flow needs uniform bends and consistent spacing. Using CNC tube-bending machines, we shape the tubing into tight, accurate coils without kinks or flattening. Automated mandrel bending preserves the tube’s roundness, ensuring no hotspots or pressure drops:

  • Mandrel support inside bends prevents tube collapse.
  • Controlled springback compensation guarantees the coil matches your design drawing.

3. Robust Assembly & Brazing

Once bent, we assemble the coils onto custom-designed headers and support frames. Our skilled technicians position each tube with jig fixtures to maintain exact pitch and alignment. Then, using vacuum-controlled brazing ovens:

  • Uniform silver-based filler ensures leak-proof joints.
  • Controlled atmosphere (nitrogen purge) prevents oxidation for spotless, high-strength bonds.

4. Protective Coating & Surface Finish

An evaporator in an ice machine faces moisture, cleaning chemicals, and frequent defrost cycles. We apply food-grade, non-toxic powder coatings or clear passivation on stainless components to:

  • Inhibit corrosion and scale buildup.
  • Simplify cleaning and maintenance.
  • Maintain smooth surfaces for efficient heat exchange.

5. Rigorous Performance Testing

Before shipping, every evaporator undergoes a full QA regimen:

  • Pressure & leak test at 1.5× maximum working pressure.
  • Thermal performance check under simulated load conditions.
  • Dimensional inspection to verify coil geometry and mounting points.

Detailed test reports and traceable certificates are provided so you can commission your ice machine with confidence.

6. Global Support & Installation

As an established exporter of evaporators, low-temperature units, and crystallizers, we back our products with:

  • On-site installation guidance via video call or in person.
  • Operator training on safe startup, defrost cycles, and routine maintenance.
  • Spare parts availability and responsive service network across key markets.
