Frequently asked questions

Does Particulair deliver across the EU?

Yes. We deliver HARDO products to customers throughout the EU within the European customs territory. Scandinavia is our primary market, but we regularly handle orders from other EU countries. We do not deliver outside the European customs territory. Please contact us for details on lead times and freight costs for your project.

Can I request a quotation without knowing the exact product code?

Yes, absolutely. It is our job to help you specify the right product. Describe your installation, zone classification, and overall requirements, and we will provide a concrete proposal. You do not need to know HARDO product codes in advance.

Can Particulair assist with ATEX documentation for authorities?

We supply all available product documentation from HARDO and Grupa WOLFF, including ATEX certificates, IECEx certificates, EU declarations of conformity, user and installation instructions, and technical data sheets. For the ATEX risk assessment and Ex area classification itself, we recommend working with an accredited specialist, as this falls outside Particulair's scope of services.

What is the difference between ATEX and IECEx, and do I need both?

ATEX is the European directive (2014/34/EU) for equipment used in explosive atmospheres and is mandatory in the EU and EEA. IECEx is an international standard issued by the IEC, used primarily for installations outside Europe or for export projects requiring global certification. Many HARDO products are certified to both standards. Let us know where the equipment will be used, and we will advise on the relevant certification.

Does Particulair offer technical support after delivery?

Yes. We are available for technical advice even after delivery. If you have questions about installation, maintenance, or the operational limits of a product, please do not hesitate to contact us. For specialised questions, we can draw directly on Grupa WOLFF's technical expertise when needed.

Can HARDO products be delivered with special markings or customisation?

Certain HARDO products can be delivered with specific customisations, such as particular cable entry configurations, terminal layouts, or surface treatments. This is arranged directly with Grupa WOLFF and may affect lead times. Contact us and we will investigate the options for your specific requirement.

What are typical lead times for HARDO products?

HARDO products are primarily manufactured to order by Grupa WOLFF in Poland. Lead times typically range from 2 to 6 weeks depending on the product and quantity. We always confirm the expected lead time before you confirm an order, and we can help prioritise delivery if your project has a firm deadline.
