A polyester enclosure is a fibreglass-reinforced polyester casing that protects electrical, electronic or measuring equipment installed outdoors or in harsh environments. It does not rust and does not conduct electricity. Its resistance to corrosion makes it suitable for marine, industrial and urban environments, as explained by Europoly.<\/a><\/p>\n\n

This page outlines the Europoly ranges of cabinets and enclosures, the most common applications and the factors to consider before making a choice.<\/p>\n\n

<\/div>\n\n

Why choose a polyester cupboard?<\/h2>\n\n
<\/div>\n\n

Corrosion and durability<\/h3>\n\n

Europoly states that its polyester cabinets offer excellent corrosion resistance in environments classified as C3 to C5 or CX in accordance with ISO 12944 Part 2, notably due to the absence of rust. By contrast, a metal cabinet must rely on a paint system compliant with ISO 12944<\/a> and a more rigorous maintenance regime to maintain its protection.<\/p>\n\n

<\/div>\n\n

Insulation and impact resistance<\/h3>\n\n

Polyester is an insulator: the casing does not conduct electricity. Europoly manufactures IP65 and IK10 polyester enclosures made from sandwich panels comprising polyester and polyurethane foam. The IK rating, as defined by IEC 62262, measures resistance to mechanical impact.<\/p>\n\n

<\/div>\n\n

Finish and appearance<\/h3>\n\n

A surface gel coat improves resistance to chemical and atmospheric attack. The colour, shape and architectural integration are specified in the client\u2019s specifications. The manufacturing<\/a> techniques and benefits of polyester<\/a> are detailed on the website.<\/p>\n\n

<\/div>\n\n

The Europoly ranges of cabinets and enclosures<\/h2>\n\n
<\/div>\n\n

Cabinet ranges: Europoly organises its products into ranges based on size, depth and intended use. Europoly<\/p>\n\n

<\/div>\n\n

Standard enclosures and cabinets<\/h3>\n\n

The Mini Euro<\/a> range comprises standard IP65 IK10 enclosures, ranging in size from 300 x 250 x 160 mm to 800 x 600 x 300 mm. Euro Medium offers modular IP55 or IP65 IK10 enclosures made from SMC, ranging from 500 x 500 x 300 mm to 1,250 x 2,000 x 500 mm, with over 224 sizes achievable by assembling panels.<\/p>\n\n

<\/div>\n\n

Large wardrobes<\/h3>\n\n

The Maxi Euro <\/a>range comprises large IP55 or IP65 IK10 cabinets, with a gel coat finish, measuring 1,900 mm in height and between 665 and 5,325 mm in width. The Euro 1500 range comprises medium-sized enclosures with deep dimensions, ranging from 920 x 720 x 250 mm to 1,500 x 2,000 x 700 mm, and featuring UV and graffiti resistance.<\/p>\n\n

<\/div>\n\n

Street cabinets<\/h3>\n\n

Euro Urbain<\/a> is a range of diamond-tipped, anti-poster and anti-graffiti lockers, rated IP44 or IP55 IK10, measuring from 920 x 720 x 300 mm to 1,500 x 3,200 x 700 mm, designed for use in public spaces.<\/p>\n\n

<\/div>\n\n

Instrumentation and cockpits<\/h3>\n\n

Euro Instrum <\/a>offers instrumentation enclosures for transmitters, manifolds and valves. Mega Euro offers IP55 or IP65 IK10 cabinets and shelters, measuring 2,400 x 2,000 mm in cross-section and ranging from 1,000 to 4,000 mm in depth, available in single- or double-skinned insulated versions.<\/p>\n\n

<\/div>\n\n

Custom made products<\/h3>\n\n

Bespoke solutions include<\/a>, in particular, emergency stop boxes, water supply boxes, battery enclosures, energy storage cabinets, FTTH cabinets and high-voltage cabinets. The cabinet customisation<\/a> page sets out the options in detail, whilst double-walled<\/a> cabinets cater to other requirements.<\/p>\n\n

<\/div>\n\n

Contexts in which the polyester cupboard is used<\/h2>\n\n
<\/div>\n\n

Telecoms and fibre optics<\/h3>\n\n

Fibre-optic and telecoms cabinets<\/a> are constantly exposed to the elements and impacts. A rust-proof polyester casing minimises the need for maintenance.<\/p>\n\n

<\/div>\n\n

Gas<\/h3>\n\n

A gas meter box contains the meter and a supply shut-off system. According to TotalEnergies, it remains accessible at all times to network technicians.<\/a> <\/p>\n\n

We set out the selection criteria here<\/a>.<\/p>\n\n

<\/div>\n\n

Counting<\/h3>\n\n

For a power-monitored connection ranging from 37 to 250 kVA, Enedis<\/a> requires that the individual main circuit breaker remain accessible to the network operator at all times. For equipment located in the public domain, the Enedis<\/a> guidance note on additional metering specifies an enclosure equivalent to IP 43 and IK 10. The article on the outdoor polyester meter cabinet sets out these requirements in detail.<\/p>\n\n

<\/div>\n\n

Construction site<\/h3>\n\n

According to 123elec<\/a>, single-phase power<\/a> (230 V) is used to power power tools, whilst three-phase power (400 V) is used for heavy-duty machinery, such as cranes or concrete mixers. The article on single-phase and three-phase site power boxes provides further details on how to choose the right one.<\/p>\n\n

<\/div>\n\n

Road safety<\/h3>\n\n

The emergency<\/a> stop post is an example of a bespoke polyester product that is exposed to the elements and vandalism.<\/p>\n\n

<\/div>\n\n

Solar energy<\/h3>\n\n

The photovoltaic cabinet<\/a> houses the equipment for an outdoor solar installation.<\/p>\n\n

<\/div>\n\n

Water and urban spaces<\/h3>\n\n

Water hydrants are made to measure. In urban areas, a guidance document<\/a> from a departmental architecture and heritage service recommends that the hydrant boxes be integrated into the surrounding architecture: they should be the same colour as neighbouring cladding and grouped together with other street furniture.<\/p>\n\n

<\/div>\n\n

Criteria for choosing a polyester cupboard<\/h2>\n\n
<\/div>\n\n

Environment and corrosion<\/h3>\n\n

IEC 60529 does not cover corrosion caused by saline or industrial atmospheres, nor does it cover ageing due to solar radiation. The site is characterised using the IEC 60721 series (Part 3, Section 4), and its corrosivity is characterised using ISO 9223 and ISO 12944 Part 2, as detailed by Europoly.<\/a><\/p>\n\n

<\/div>\n\n

IP and IK ratings<\/h3>\n\n

The IP rating measures protection against dust and water, whilst the IK rating measures impact resistance. Details of the different levels can be found on the IP\/IK protection rating page.<\/a> A high IP rating does not protect against internal condensation.<\/p>\n\n

<\/div>\n\n

Condensation and ventilation<\/h3>\n\n

Condensation occurs when the walls are colder than the dew point of the indoor air. The balance between airtightness and ventilation is discussed in the article \u2018Polyester cupboards: ventilation or airtightness\u2019.<\/a><\/p>\n\n

<\/div>\n\n

Dimensions, installation and fittings<\/h3>\n\n

The internal dimensions must be sufficient to accommodate the equipment, its cabling and access for maintenance. To compare a cabinet and an enclosure, see the page on industrial polyester electrical enclosures.<\/a><\/p>\n\n

<\/div>\n\n

Draw up the specifications<\/h3>\n\n

A detailed set of specifications helps to avoid repeated correspondence. It may include the following points:<\/p>\n\n

    \n
  1. the context of use and the site\u2019s corrosivity class;<\/li>\n\n\n\n
  2. the clear dimensions, including fittings and access points;<\/li>\n\n\n\n
  3. the required IP and IK ratings;<\/li>\n\n\n\n
  4. thermal management: ventilation, insulation and heating;<\/li>\n\n\n\n
  5. colour and finish, as specified by the client;<\/li>\n\n\n\n
  6. installation method: plinth-mounted, wall-mounted or pole-mounted;<\/li>\n\n\n\n
  7. internal electrical wiring, to be carried out by Polyelec<\/a> in conjunction with the control cabinet;<\/li>\n\n\n\n
  8. interior fittings, to be carried out by Gensollen<\/a> if required.<\/li>\n<\/ol>\n\n
    <\/div>\n\n

    From the kit to the complete project: Europoly, Gensollen and Polyelec<\/h2>\n\n

    <\/div>\n\n

    Frequently Asked Questions<\/h2>\n\n
    <\/div>\n\n
    What is the difference between a polyester cupboard and a metal cupboard?<\/strong>

    Polyester cabinets do not rust and do not conduct electricity. Metal cabinets must be coated with a paint system that complies with ISO 12944 and require a more rigorous maintenance regime. The full comparison can be found in the article \u2018Polyester cabinets or metal cabinets\u2019.<\/a><\/p> <\/div>

    What IP and IK ratings are required for a polyester cabinet?<\/strong>

    Europoly manufactures IP65 and IK10 polyester enclosures. Depending on the range, the ratings range from IP44 to IP65 and up to IK10. Further details can be found on the IP\/IK protection rating page.<\/a><\/p> <\/div>

    How can you minimise condensation in a polyester cabinet?<\/strong>

    Effective thermal management combines insulation, colour, site selection, controlled ventilation \u2013 and even heating \u2013 with a drainage plan. The article \u2018Polyester enclosures: ventilation or sealing<\/a>\u2019 sets out these options in detail.<\/p> <\/div>

    Polyester enclosures and ATEX zones: what are the requirements?<\/strong>

    The enclosure on its own is never ATEX-compliant by nature: compliance depends on the overall design, the protection strategy and the certification of the entire assembly, as Europoly<\/a> points out. Europoly enclosures meet the requirements for ATEX zones, without claiming compliance.<\/p> <\/div>

    What size polyester cupboard should I choose?<\/strong>

    From enclosures measuring 300 x 250 x 160 mm to cabinets 1,900 mm high and 5,325 mm wide, and on to enclosures measuring 2,400 x 2,000 mm, the ranges cover a wide spectrum. The internal dimensions must accommodate the equipment, its cabling and access for maintenance.<\/p> <\/div>

    Who is responsible for wiring the cabinet?<\/strong>

    Europoly manufactures the polyester enclosure. Polyelec<\/a>, a group company, carries out the internal electrical wiring and electrical integration. Gensollen<\/a> designs the interior fittings for the cabins and enclosures.<\/p> <\/div> <\/div>\n\n
