Climetal designs and manufactures custom aluminium microchannel coils for HVACR, refrigeration, industrial cooling and mobile equipment.
Our engineering team works closely with OEM manufacturers to define the thermal performance, geometry, circuiting and connections required for each system, including microchannel condenser coils, evaporator coils and single-phase solutions for dry coolers, free coolers and radiators.
Performance may vary depending on the coil design, operating conditions and system used for comparison.
Selecting the right microchannel coil involves more than choosing a standard component. Required capacity, airflow, refrigerant or fluid, pressure drop, available space and system configuration all influence the final design.
Climetal develops custom microchannel coils around the actual operating requirements of each OEM application. In addition to manufacturing the coil, our engineering team supports customers throughout the definition and integration of microchannel technology into new and existing equipment.
This collaborative approach allows manufacturers to develop compact, lightweight and efficient thermal systems without having to adapt their equipment around a pre-existing coil design.
Each coil is designed according to the required thermal performance, available dimensions, operating conditions, connections and production needs of the project.

Although final performance depends on the application and coil design, aluminium microchannel technology can provide more efficient heat transfer, lower internal volume and lighter, more compact equipment.
Flat tubes with a small hydraulic diameter and brazed aluminium fins create continuous thermal contact between the main heat-transfer surfaces.
Lower internal volume can reduce refrigerant requirements and help OEMs design more compact thermal systems.
The slim tube profile can reduce airflow resistance, supporting fan, acoustic and energy-performance optimisation.
All-aluminium construction reduces weight compared with conventional copper-tube solutions and can simplify handling and integration.
Integration options include copper-aluminium brazed connections and mechanical O-ring fittings, depending on project requirements.
Alloy selection helps control corrosion risk, with additional protection available for demanding environments through Climetal 5K Coating .
Many OEM projects require a coil designed around the equipment rather than equipment adapted around a standard coil.
Climetal evaluates the available technical data and defines a custom microchannel coil according to the required performance, installation limits and production needs.
The performance and service life of a microchannel coil depend on more than its nominal capacity. Operating temperatures, refrigerant distribution, airflow, pressure drop, environmental exposure and connection design must be considered during the engineering phase.
Evaporator and heat-pump projects require specific attention to refrigerant distribution and operating conditions. Systems combining aluminium heat exchangers with copper piping also require the connection method and installation environment to be evaluated.
Climetal considers all these factors when defining the geometry, circuiting, materials and connections of each coil, helping OEM manufacturers select a configuration adapted to the actual conditions of their equipment.
Climetal supports each project from the initial application review through coil definition, manufacturing and integration.
Analysis of capacity, airflow, dimensions, refrigerant or fluid and operating temperatures.

Climetal develops solutions for refrigerants and fluids such as R410A, R32, R1234yf, propane, ammonia, water and glycol. The materials, geometry, connections and operating limits are evaluated and defined individually for each project.
Climetal also provides an online selection tool that allows customers to estimate equipment performance under different operating conditions.
A microchannel coil is an aluminium heat exchanger made from flat tubes containing multiple small internal channels, together with aluminium fins and headers. The tubes and fins are joined through a brazing process to create continuous thermal contact.
Climetal develops two-phase coils for condenser and evaporator applications, as well as single-phase fluid coils for dry coolers, free coolers, radiators and other thermal systems.
Yes. Climetal designs custom coils according to the required capacity, dimensions, refrigerant or fluid, airflow, pressure drop, circuiting, connections and operating conditions of the customer's equipment.
Yes. Microchannel technology is widely used in condenser applications and can also be applied to evaporator coils. Evaporator projects require a detailed evaluation of refrigerant distribution, circuiting, pressure drop and expected operating conditions.
Yes. Single-phase microchannel fluid coils can be developed for water and glycol applications such as dry coolers, free coolers and industrial radiators. The final design depends on capacity, fluid conditions, pressure drop and equipment layout.
Refrigerant compatibility depends on the coil design, the materials used, the operating pressure and the requirements of each application. Climetal develops microchannel solutions for refrigerants such as R410A, R32, R1234yf, propane and ammonia, among others.
