Polaris- Overview
Polaris Plate Heat Exchangers is a Louisville, Kentucky-based manufacturer with a focused mission: they make plate heat exchangers and nothing else. That specialization is not a limitation. It is the reason engineers and contractors who work with Polaris come back to them project after project. When a manufacturer dedicates its entire operation to one product category, the depth of engineering knowledge, the range of configurations available, and the quality of application support all reflect that commitment.
Polaris manufactures a comprehensive lineup of plate heat exchanger types to cover the full range of commercial and industrial heat transfer demands. Their product range includes plate and frame exchangers, brazed plate exchangers, safety pair double wall exchangers, semi-welded plate exchangers, shell and plate exchangers, all-welded exchangers, and free-flow plate exchangers. Each type is engineered to address a specific set of application requirements, whether that means handling aggressive fluids, meeting potable water safety standards, operating under high pressure, or fitting into a tight mechanical room footprint.
Most Polaris heat exchangers are manufactured at their Louisville facility and engineered to the specific demands of the individual job. Quotation turnaround is fast, special materials and unusual designs are handled without difficulty, and their nationwide network of manufacturer’s representatives keeps local support accessible for engineers, contractors, and facilities teams who need answers quickly.

WHY MERION PUMP AND POLARIS
Heat exchangers sit at the center of a lot of what Merion does. Whether the application is hydronic heating, domestic hot water, district energy, or building isolation, the heat exchanger is where the system either performs or falls short. Choosing the right one for the right application requires more than picking a product off a shelf. It requires a manufacturer with the range to cover what the job actually demands and the technical depth to back up the selection.
Polaris has been that manufacturer for Merion across a long and well-developed relationship. Their plate heat exchanger lineup covers the full range of configurations that HVAC and building services applications call for, from standard brazed plate units for straightforward hydronic applications to safety pair double wall exchangers where potable water and heating fluid cannot come into contact under any circumstances. That last point matters especially in healthcare, institutional, and domestic hot water applications where code and safety requirements leave no room for compromise.
What has kept the relationship strong over time is the way Polaris operates. Quotes come back fast. Custom requirements get handled without the back-and-forth that slows other manufacturers down. And when a project has unusual demands, whether that means special materials, non-standard sizing, or a configuration that does not fit neatly into a catalog page, Polaris engages with the problem rather than redirecting to the closest standard option.
For Merion customers, that means when a heat exchanger comes into a project through us, it has been selected with both the application and the building in mind, and it is backed by a manufacturer we trust to support it.
FEATURED PRODUCTS
Polaris Plate and Frame Heat Exchanger
The flagship Polaris product and the right starting point for most commercial HVAC and hydronic applications. Plate and frame exchangers are fully gasketed and cleanable, making them a practical long-term choice for building heating and cooling systems where maintenance access matters. Polaris engineers each unit to the specific job, with plate geometry, patterns, and connection sizes configured to the actual system requirements rather than a closest standard match.
Polaris Brazed Plate Heat Exchanger
For applications where a compact, permanently sealed unit is the right fit, the Polaris brazed plate exchanger delivers efficient heat transfer in a smaller footprint without the gaskets and frame of a traditional plate and frame unit. A common choice for hydronic heating, domestic hot water, and refrigeration applications in commercial buildings where space is at a premium and the fluid streams are clean and compatible.
Polaris Safety Pair Double Wall Heat Exchanger
When the application involves potable water on one side of the heat exchanger, a standard single-wall design is not an option. The Polaris Safety Pair double wall exchanger provides a physical barrier between fluid streams, meeting code requirements for domestic hot water heating and other applications where cross-contamination between potable and non-potable circuits cannot be permitted. A critical specification in healthcare, institutional, and residential building applications.
