Our products

Air-Oil Exchangers

EMMEGI air-oil heat exchangers are used for the cooling of hydraulic circuits using ambient air conveyed over the radiator by a fan driven by an electric or hydraulic motor as a coolant and are normally installed in return line.

Water-Oil Exchangers

Water-oil exchangers are used for the cooling of hydraulic circuits and are normally installed in return line.

Water-Oil exchangers with brazed plates

Plate heat exchangers are made of corrugated plates. The plates are positioned at 180º to each other, creating a lattice of intersecting channels.

Autonomous Cooling Units

Low-noise independent air-cooling units that operate using the principle of recirculation, autonomously collecting, cooling, filtering and returning the fluid to the tanks.

ATEX certified heat exchangers

The HPԐX SERIES heat exchanger line was created for customers requiring a product that combines high performance and safety in hazardous area.

Marine heat exchangers

The HPAM SERIES heat exchanger line has been developed for applications installed in an offshore marine environment. These products are ideal in extremely aggressive and corrosive environments. Special materials and treatments guarantee life cycles like those of the UNI EN ISO 12944 (C5) directives.

Combi Coolers for Compressors

Our experience in the field of compressors has allowed us to develop this range of combi coolers called CC which, due to their simple layout, are easy to adapt to multiple compressors of different powers.

Project-based heat exchangers

EMMEGI specialises in the design of heat exchangers to customer specifications. A customised project originates from the interface with the customers’ technical offices, from the analysis and collection of all the heat exchange, dimensional and regulatory specifications.

Accessories

In addition to the complete product, EMMEGI supplies a wide range of accessories:

  • Adjustable thermostats
  • Fixed temperature thermostats
  • Thermostatic valves
  • 3-way temperature control valves
  • Electronic variator

Hydraulic Oil Coolers – FAQs

What is the best way to cool hydraulic oil?

The best way to cool hydraulic oil is by using hydraulic oil coolers, which effectively manage the temperature of the oil to prevent overheating and maintain system efficiency. Air-cooled or water-cooled oil coolers are commonly used depending on the specific needs and environmental conditions.

How does a hydraulic oil cooler work?

A hydraulic oil cooler works by transferring the heat from the hydraulic oil to a cooling medium, typically air or water. The oil circulates through the cooler where it is exposed to cooling fins or plates that dissipate the heat, thus lowering the temperature of the oil before it returns to the hydraulic system.

Are oil coolers worth it?
Yes, oil coolers are worth it, especially for hydraulic systems in industrial or mobile applications where overheating can cause significant damage and downtime. Hydraulic oil coolers help maintain optimal operating temperatures, reduce wear and tear on components, and extend the life of the equipment.
What are the different types of hydraulic oil coolers?

The different types of hydraulic oil coolers include air-cooled oil coolers, water-cooled oil coolers, and specialized coolers like brazed plate heat exchangers and combination coolers. Each type has its own advantages and is suited to particular industrial environments and cooling requirements.

How do I choose a hydraulic oil cooler?

To choose a hydraulic oil cooler, consider factors such as the type of hydraulic system, the ambient environment, cooling capacity required, and space constraints. It’s also important to assess the cooler’s compatibility with the hydraulic fluid used and the expected thermal load of the system.

What is the best type of oil cooler?

The best type of oil cooler depends on your specific requirements. Air-cooled oil coolers are versatile and suitable for environments lacking water resources, making them easier to maintain. Water-cooled oil coolers provide more efficient cooling but require a reliable water source and are best for applications with high heat loads.
