COMPANY – Is EURODIFROID a French company<\/strong>?<\/summary>\n

Yes, our design and manufacturing site is located in Seiches-sur-le-Loir, near Angers (France).<\/p>\n<\/details>\n\n\n\n

COMPANY – Do you offer standard <\/strong>or custom-made<\/strong> equipment?<\/summary>\n

Both!
And that is precisely what makes us unique.<\/p>\n\n\n\n

We offer standard industrial chillers and air conditioners, so these units are available with relatively short delivery times (1-2 days at best).
Our teams can, of course, add options to these chillers to adapt them to your needs. Depending on the complexity, we can tell you the additional time required to prepare these components.
Furthermore, we design cooling solutions: this means our Engineering Department can be called upon to design a custom product tailored to your specifications. We can work on theoretical studies, prototyping, small production runs, or even larger-scale production (as our industrial equipment is highly modular).
Whatever your needs, please don’t hesitate to contact us: our sales and technical teams will guide you toward the most suitable solution (standard, with options, or custom).<\/p>\n<\/details>\n\n\n\n

COMPANY – Do you offer more environmentally friendly solutions<\/strong>?
(ecologically friendly refrigerant, low energy consumption)?<\/summary>\n

Yes, eco-design is an integral part of our expertise and our advisory role.<\/p>\n\n\n\n

We are regularly asked about this type of issue (for a new project or for updating an existing device) and have many levers to reduce the economic and ecological impact of your device during its design.<\/p>\n\n\n\n

Mechanical, refrigeration, hydraulic or electronic optimization\u2026 many avenues can be explored to reduce your operating costs and the environmental footprint of your refrigeration unit.<\/p>\n<\/details>\n\n\n\n

– Similarly, we are always happy to welcome clients to our premises (for business discussions, technical acceptance\/validation, project work, etc.), which allows us to share expertise and best practices;
– Furthermore, we regularly hire interns and apprentices to provide them with practical, hands-on knowledge of our various business lines.<\/p>\n\n\n\n

So please do not hesitate to contact us and submit your need for support.<\/p>\n<\/details>\n\n\n\n

SERVICE – Do you deliver everywhere<\/strong> (France, international)?<\/summary>\n

Yes: Located near Angers, France, we regularly ship our devices worldwide via various logistics providers.
Of course, regardless of the country of installation, we take great care to anticipate and ensure that the device arrives perfectly suited to its intended use (electrical adaptations according to the country’s standards, packaging adjustments if necessary, etc.).<\/p>\n<\/details>\n\n\n\n

TECHNICAL – What is floating HP<\/strong>?<\/summary>\n

Floating high pressure (HP) is an intelligent technique that adapts the condensing pressure to external conditions, improving energy efficiency and extending the lifespan of refrigeration equipment.<\/p>\n\n\n\n

This control strategy is widely used in refrigeration systems: instead of maintaining a fixed condensing pressure (for example, 14 bar, which corresponds to a condensing temperature of around 40\u00b0C), the high pressure is allowed to “float” and automatically adjust according to the external temperature or actual heat rejection conditions.<\/p>\n\n\n\n

The result: a significant reduction in electricity consumption<\/strong> (10 to 20% savings on average), less mechanical wear on the compressors, all operating automatically without manual adjustments.<\/p>\n<\/details>\n\n\n\n

TECHNICAL – Do your products comply with current European standards <\/strong>(CE, F-Gas, etc.)?<\/summary>\n

Yes, we are of course compliant with current standards and are here to advise you on these matters.
We regularly monitor this information and exchange information with our suppliers to benefit from even more specialized knowledge.
We provide you with all the relevant technical documents, allowing you to complete your compliance file.
(More information about air conditioning and cooling systems can be found on\u00a0AFCE<\/a>.)<\/p>\n<\/details>\n\n\n\n

TECHNICAL – What is glycol<\/strong>?<\/summary>\n

Glycol is a type of alcohol commonly used as a heat transfer fluid in heating, ventilation, air conditioning and refrigeration (HVAC-R) systems.<\/p>\n\n\n\n

There are two main types of glycol used in cooling systems:
– Ethylene glycol<\/strong> (EG): very effective from a thermal and fluidity point of view, but unfortunately quite toxic;
– Propylene glycol<\/strong> (PG): being more viscous, it is also slightly less effective. However, it is better suited to certain uses, such as in the food and beverage, pharmaceutical, etc. industries.<\/p>\n\n\n\n

Most often mixed with water (the glycol content of the mixture is then expressed as a percentage), glycol forms an antifreeze solution that circulates in the cooling system.<\/p>\n\n\n\n

Its main functions are:
– Lowering the freezing point<\/strong>: glycol prevents water from freezing in pipes at low temperatures, which could damage equipment (example: a 50% glycol solution can protect down to about -35\u00b0C);
– Raising the boiling point<\/strong>: it also allows the fluid to operate at higher temperatures without boiling, useful in certain industrial systems;
– Preventing corrosion:<\/strong> glycol solutions often contain corrosion inhibitors that protect metallic components (such as aluminum, copper, or steel) from rust;
– And finally, improve heat exchange<\/strong>: even though pure glycol has a lower heat capacity than water, it remains effective as a heat transfer fluid in demanding environments.
It is therefore naturally found in many “cooling” devices: industrial and commercial refrigeration units, chillers for cooling buildings or machines, process cooling systems (e.g., breweries, laboratories), etc.<\/p>\n<\/details>\n\n\n\n

TECHNICAL – What is a microchannel <\/strong>condenser?<\/summary>\n

Microchannels are a heat exchanger technology (for condensers or evaporators) where the refrigerant circulates through very small, parallel aluminum channels (often just a few millimeters in internal diameter).
The refrigerant is distributed across several aluminum microtubes, and the large exchange surface area (thanks to the multiple thin channels and external fins) allows for more efficient heat transfer.
Furthermore, aluminum, being lighter and 100% recyclable, also offers better thermal conductivity than copper.<\/p>\n\n\n\n

Advantages include: reduced refrigerant charge (30% to 40% on average), resulting in a smaller environmental footprint; improved energy efficiency (thanks to optimized heat exchange); and increased durability (due to better resistance to corrosion and impacts).
This is one of the technical solutions our engineers can offer to optimize your operating costs.<\/p>\n<\/details>\n\n\n\n

TECHNICAL – What is a skid <\/strong>(or hydraulic skid<\/strong>)?<\/summary>\n

A hydraulic skid is a prefabricated module that integrates all the hydraulic components necessary for the proper functioning of a cooling (or heating) system into a single chassis (the “skid”).
It typically includes (depending on the specific application): circulation pumps, valves (shut-off, regulating, and safety), buffer tanks (or reservoirs), bypasses, and an automated control system.
It is essentially a turnkey hydraulic power unit, ready to be connected to the existing piping network on-site.
Installation time is therefore significantly reduced, and this system also often offers greater flexibility, increased reliability, and easier maintenance.<\/p>\n\n\n\n

In short, this “mini hydraulic power unit” is often a very useful addition for managing hydraulic systems independently of the cooling function.<\/p>\n<\/details>\n\n\n\n

TECHNICAL – What is PID<\/strong>?<\/summary>\n

The P&ID (Piping & Instrumentation Diagram) is a diagram that describes the entire piping and instrumentation circuit of a system.
In a refrigeration circuit, you’ll find various components, represented by symbols, such as the compressor, evaporator, condenser, and expansion valve. Depending on the system, you might also find sensors, check valves, pumps, tanks, etc.
It’s therefore a crucial product design tool because it will guide component purchasing, assembly methods, and more.
And this document is yours! Once your equipment design is fully finalized and approved, we can provide you with this P&ID for your internal use.<\/p>\n<\/details>\n\n\n\n

TECHNICAL – What is GWP<\/strong>?<\/summary>\n

The Global Warming Potential (GWP) is the ratio of a gas’s warming potential to that of CO2, thus indicating its harmfulness in terms of the greenhouse effect.
Each refrigerant is assigned a GWP index, which allows for the assessment of its environmental impact.

Example <\/span>: the GWP of R410a is 2100 (i.e., 2100 times more harmful than CO2), while the GWP of R1234yf is only 4.<\/p>\n\n\n\n

Note that some fluids can be interchanged (with some more or less significant adaptations to the device).<\/p>\n\n\n\n
