Serpentine heat exchangers for small cooling applications

Kaltra offers the latest heat transfer technology for electronics cooling, cooling of laser devices, medical appliances, and other small cooling applications with serpentine heat exchangers based on microchannel technology.

Serpentine coils are the smallest and most versatile heat exchangers in the industry for refrigerant condensers and cooling applications. Based on microchannel technology, each coil is designed to deliver maximum heat transfer, operational reliability, and can be simply integrated into the casing.

Serpentine coils offer:

• Minimum weight
• Compact design with 1.25” thickness
• High heat transfer performance
• 32 bar or higher pressure ratings

Serpentine coils can be used with R134a, R404a, R407c, R410a, and other refrigerants as condensers in compressorized and pumped loop refrigerant systems. They can also be configured as evaporators for non‐condensing cooling applications.

Coil orientation, whether vertical, horizontal/flat, stationary, or in constant motion, does not affect overall performance due to the single tube, serpentine design.

Each coil is all-aluminium, integrally brazed, and rated for 32 bar operating pressures or higher. All models have aluminum or copper connections, optional mounting methods, and a full range of sizes from 25mm to over 450mm.
