WATER-OIL EXCHANGERS CATALOGUES
Menu
The Emmegi Water-Oil Heat Exchangers are designed for cooling hydraulic oil or compatible fluids, with flow rates from 5 to 800 l/min and thermal capacity up to 8.3 kW/°C. Made with materials such as copper, brass, AISI 304, and CuNi10, they operate up to 12 bar and 120°C. Available with fixed, removable, or immersed tube bundles and inspectable water circuits. High efficiency, reliability, and long service life for industrial hydraulic systems.
The Emmegi Water-Oil Heat Exchangers are a highly reliable technical solution for cooling hydraulic circuits, making them ideal for return line applications. Designed to deliver high thermal performance, they are manufactured using premium materials and precision machining to ensure maximum efficiency even under demanding operating conditions.
A distinguishing feature of the Emmegi range is the inspectable water circuit, available in 1, 2, or 4-pass configurations, allowing maximum adaptability to various system requirements. These heat exchangers can also be equipped with an integrated thermostatic valve, which optimizes water consumption while maintaining consistent performance.
Emmegi Water-Oil Heat Exchangers are available in multiple versions:
Materials used include: copper, brass, CuZn37, CuZn40, Fe510.2 steel, AISI 304, CuNi10Mn1Fe, with gaskets made of rubber-cork or graphite-kevlar in designated versions. Tubes are made of CuDHP, while tube plates, baffles, and shells are made of specific materials depending on the series (MG, MGC, MGE, MGB, etc.).
These exchangers support a wide range of fluids:
For specific fluids, a tailored technical evaluation is available upon request.
The water side is easily inspectable by removing the end caps, allowing for tube cleaning in case of deposit buildup. The oil side can be cleaned by reverse-flow flushing with perchloroethylene for approximately 30 minutes, followed by rinsing with hot water.
