Universal Dual Pass Bar & Plate Oil Cooler Heat Exchanger (Medium Silver)
The Mishimoto Universal Dual Pass Bar & Plate Oil Cooler (Medium) uses a durable bar & plate design with 10AN fittings. It is built from 100% aluminum and features CNC-machined endtanks for robust cooling performance. Best for custom automotive oil cooling needs where compact, lightweight construction matters. Caution: Aluminum construction may require careful mounting and corrosion considerations in harsh environments.
Best For
- Custom engine builds needing a compact oil cooler with flexible fittings.
- Applications prioritizing light weight and simple installation.
Universal Dual Pass Bar & Plate Oil Cooler Heat Exchanger (Large)
This larger Mishimoto unit shares the same bar & plate architecture with 10AN connections and aluminum construction, designed for higher flow and cooling capacity. It’s better for larger engines or high-heat environments where more surface area improves oil cooling. Caution: Increased size may require more mounting clearance and different hose routing compared to the medium model.
Best For
- High-output engines or performance builds needing more oil cooling capacity.
- Systems where space permits a larger cooler than the standard unit.
AB Plate Heat Exchanger, 4″x12″ 30 Plates
The AB Plate Heat Exchanger uses 316L stainless steel plates brazed at the edges with copper, delivering robust leakage resistance and high pressure tolerance. It’s a solid choice for water-to-water or radiant heating projects where compact, efficient heat transfer is essential. The 30-plate configuration balances surface area with footprint. Caution: Copper brazing requires careful material compatibility with your fluids and may demand precise installation.
Best For
- Floor heating, hydronic systems, or water-to-water cooling with reliable corrosion resistance.
- Projects needing strong thermal performance in a compact package.
BestEquip Heat Exchanger 3″x7.5″ 60 Plates
The BestEquip 60-plate brazed stainless steel heat exchanger delivers high thermal efficiency through turbulent flow, with four thickened BSP FPT ports for easier installation. It is CE-certified and designed for hydronic heating or industrial transfer tasks. Caution: High plate counts increase potential pressure drop, so ensure compatible pump sizing in your system.
Best For
- Hydronic heating or cooling projects requiring strong heat transfer and a robust, compact exchanger.
- Applications needing multiple port options for flexible piping.
ALECOIL 4″x12″ 40 Plates Heat Exchanger
ALECOIL offers a 4″x12″ plate heat exchanger with 40 plates and 1″ MPT ports. Made from 316L stainless steel and copper brazed, it’s designed for water-to-water transfer with emphasis on high heat transfer efficiency. Caution: The asymmetric fish bone plate design, while efficient, can require careful pressure management to minimize secondary-side pressure drop.
Best For
- Water-to-water heating or cooling systems requiring a compact, efficient exchanger.
- Applications where a 1″ MPT port fit is essential for installation.
Buying Guide
Key considerations when choosing a bar and plate heat exchanger include material compatibility, plate count, port sizes, and intended fluid. For oil cooling, aluminum oil coolers offer light weight and corrosion resistance, but confirm compatibility with your oil and temperature range. For water-to-water or radiant heating, 316L stainless steel plates brazed with copper edges provide strong durability and leak resistance, though installation may require attention to pressure drops and pump sizing.
- Purpose alignment: Oil cooling vs. water-to-water transfer vs. floor heating. Choose based on the primary fluid and application.
- Plate count and size: More plates increase heat transfer but also footprint and pressure drop. Match to your temperature delta and available space.
- Materials: Aluminum is light and corrosion resistant for oils; 316L stainless steel with copper brazing works well for water systems and aggressive fluids.
- Ports and fittings: Ensure port size (MPT/BSP) and thread type fit your piping and hoses.
- Installation considerations: Clearances, mounting orientation, and required pumps or flow rates.

FAQ
- What is a bar and plate heat exchanger?
Answer: A type of heat exchanger that uses alternating bars and plates to maximize surface area for heat transfer between two fluids. - Which material is best for oil cooling?
Answer: Aluminum units are common for oil cooling due to light weight and decent corrosion resistance; verify oil compatibility. - How do I choose plate count?
Answer: Higher plate counts improve heat transfer but require more space and may raise pressure drop; match to your temperature difference and pump capacity. - What is the difference between 316L stainless and aluminum exchangers?
Answer: 316L stainless offers excellent corrosion resistance for water-based systems; aluminum is lighter and suitable for oil cooling with proper seals. - Do I need a specific port size?
Answer: Yes; ensure MPT or BSP port sizes fit your hoses or fittings and plan pipe routing accordingly. - Are brazed plate heat exchangers leak-proof?
Answer: They are designed to be robust, but proper installation and sealing are essential to prevent leaks under pressure.
