Precision-engineered MCHEs through smart component selection

In today’s competitive HVAC and refrigeration market, system designers are increasingly challenged to balance performance, cost, and sustainability. At Kaltra, we recognize that one-size-fits-all solutions simply don’t work—especially when it comes to microchannel heat exchangers (MCHEs). That’s why we’ve invested heavily in developing a wide nomenclature of parts for our MCHEs, offering unmatched flexibility, customization, and value to our customers.

What Does a “Wide Nomenclature” Mean for You?

Kaltra’s comprehensive selection of MCHE components empowers engineers and OEMs to fine-tune heat exchanger designs to their exact specifications. This results in:

• Optimized Performance – With a broad range of multiport flat tubes (microchannel tubes) of varying widths, heights, and tube port geometries, Kaltra enables precision control over heat transfer efficiency, pressure drop, and refrigerant distribution. This means you get an MCHE tailored to the precise thermal and flow characteristics of your system.
• Design Flexibility – Whether you’re targeting compactness, high capacity, or specific operating temperature deltas, our modular component approach makes it possible. Our selection of fins—including various profiles, materials, and densities—further allows for detailed customization of heat transfer surfaces and airflow characteristics.
• Unmatched Variety – With over 80 tube geometries, more than 10 fin pitches, and over 20 manifold diameters and wall thicknesses, Kaltra offers thousands of possible coil design combinations—far more than any competitors in the market. This extensive range allows precise tailoring to application needs while ensuring the best possible balance between performance and cost.
• Cost Reduction – By selecting exactly the right combination of tubes, fins, and headers, Kaltra avoids overengineering and excess material use. This targeted approach reduces both production costs and refrigerant charge, contributing to lower upfront and operating expenses.
• Sustainability and Compliance – Our tailored solutions help customers meet increasingly stringent environmental regulations. The ability to minimize refrigerant volume without compromising performance supports sustainability goals and regulatory compliance.

Accelerate Design with Kaltra’s MCHE Selection Software

To complement our manufacturing capabilities, Kaltra offers advanced MCHE selection software, designed to help customers quickly configure and evaluate coil designs based on their unique requirements.

• Fast and Accurate Design – The intuitive interface and powerful algorithms—enhanced with AI-driven predictive modeling—enable users to generate optimized coil layouts in minutes. With just a few inputs—cooling/heating loads, airflow, refrigerant type, and operating conditions—the software intelligently proposes highly efficient solutions using Kaltra’s full component range. Based on the selected application (condenser, evaporator, or fluid coil) and user-defined priorities—such as minimizing refrigerant charge or pressure drops or specific size of the coil—the AI engine recommends the most appropriate combination of tubes, fins, and headers for optimal performance and cost efficiency.
• Immediate Performance Insights – Users gain real-time feedback on critical performance indicators such as heat transfer capacity, pressure drops, temperature differences, and refrigerant charge—helping guide decisions early in the design process.
• Expert Validation – While the software speeds up coil selection, engineering verification remains essential. Each proposed design can be reviewed and validated by Kaltra’s experienced thermal engineers to ensure full technical reliability and performance in the field. This extra layer of validation gives customers confidence in both the simulation results and the final product.
