Stainless Steel Coaxial Heat Exchangers Ready for Global Delivery

We continue to support global customers with high-performance coaxial heat exchangers designed for heat pumps, chillers, dehumidifiers, laser cooling systems, oil cooling, and industrial process equipment. Our latest batch of stainless steel coaxial heat exchangers has completed production and successfully passed pressure and quality inspections before shipment.

1. Precision Manufacturing for Demanding Applications

Coaxial heat exchangers—also known as tube-in-tube heat exchangers—are preferred for systems requiring:

• High pressure resistance

• Excellent fouling resistance

• Compact installation space

• Efficient heat transfer with turbulent flow characteristics

The units shown above are manufactured with stainless steel 304/316L, offering long service life in corrosive environments such as seawater cooling, chemical processing, and high-humidity HVAC systems.

2. Production Highlights

Each heat exchanger is produced using:

• Precision-wound spiral coils to ensure consistent clearance and flow distribution

• Fully annealed tubing for improved thermal performance

• High-strength brazed or welded joints to withstand long-term cyclic pressure

• Customizable connection sizes according to customer requirements

Our manufacturing process maintains strict dimensional tolerances to ensure stable performance in high-efficiency heat pump and refrigeration circuits.

3. Quality Inspection Before Delivery

Before shipping, every coaxial heat exchanger undergoes:

• Hydrostatic pressure test (up to 3.0–4.5 MPa depending on model)

• Helium leak detection

• Cleaning and drying of inner/outer circuits

• Visual inspection for coil uniformity and weld integrity

These procedures ensure that each unit is ready to be integrated into the customer’s equipment with zero additional preparation.

4. Applications Supported

VRCOOLER coaxial heat exchangers are widely used in:

• Air-to-water and water-to-water heat pumps

• Residential & commercial chillers

• Industrial coolant circulation systems

• Laser machines and CNC equipment

• Marine and offshore cooling devices

• Oil cooling for compressors and hydraulic systems

Their robust structure and self-cleaning turbulent flow make them ideal for conditions where plate heat exchangers are prone to fouling or clogging.

5. Global Delivery & Custom Solutions

Whether your project requires a single prototype or bulk quantities, VRCOOLER provides:

• Fast production cycles

• Safe export packaging

• OEM/ODM customization

• Engineering support for thermal design and selection

We ensure reliable, on-time delivery to customers worldwide.
