Engineered specifically for modern dairy farms and milk processing systems, our sanitary coaxial tube coil heat exchanger delivers high thermal efficiency in a compact footprint. Installed as an In-Line Pre-Cooler or Final Chill Module before the bulk storage tank, it rapidly pulls raw milk down from approximately 38°C (100°F) to 4°C (39°F), effectively inhibiting bacterial growth and maintaining milk freshness.
Key B2B Engineering Benefits
-
Sanitary Dairy Standards
Food-Grade 316L Stainless Steel Passages: Built specifically to meet strict instant milk chilling regulations. Features smooth inner surfaces for dead-zone-free CIP (Clean-in-Place) sanitation, resisting aggressive milk acids and cleaning agents. -
Compact Integration
Optimized Coiled Geometry: Delivers maximum heat transfer surface area within a minimal spatial footprint, allowing seamless OEM integration into existing milk chilling skids, tank chassis, or compact farm refrigeration units. -
Corrosion Protection
Durable Outer Shell (SS304 / High-Grade Steel): Provides long-term structural integrity and high corrosion resistance against harsh, high-humidity farm environments and continuous thermal shock. -
High Pressure & Versatility
Multi-Refrigerant & Secondary Loop Compatibility: Safely withstands high operating pressures (30–45 bar on the tube side). Fully compatible with R410A, R407C, R134a, as well as secondary chilled water or glycol loops. -
Anti-Fouling Efficiency
High-Turbulence Corrugated Inner Design: Continuous fluid turbulence inside the coaxial tube coil maximizes thermal exchange while actively preventing milk fat buildup and scaling during peak milking hours.

Frequently Asked Questions (FAQ)
Q1: Why choose a coaxial tube coil heat exchanger instead of a plate heat exchanger for final milk chilling?
A: While plate heat exchangers excel at high-volume ambient water pre-cooling, a coaxial tube coil heat exchanger is vastly superior for direct-expansion (DX) refrigerants or high-pressure glycol loops. It eliminates gasket degradation risks, offers higher pressure limits, and maintains reliable, leak-free continuous performance.
Q2: Is this coaxial tube coil heat exchanger easy to clean using CIP systems?
A: Yes. The smooth, large-radius internal passage of the food-grade inner tube enables high-velocity CIP (Clean-in-Place) fluids to scour internal surfaces effectively, eliminating dead zones where milk fat or deposits could build up.
Q3: Can the coil dimensions and connection fittings be customized?
A: Absolutely. We offer custom coil diameters, height profiles, and sanitary connections (such as Tri-Clamp, Threaded, or Sweat fittings) to match your specific chassis layout and flow rate demands.
Q4: What refrigerants and cooling media are compatible with this unit?
A: Our coaxial tube coil heat exchangers are designed to work seamlessly with eco-friendly refrigerants including R410A, R134a, and R407C, as well as secondary chilled glycol or chilled water circuits.
