FNA vans are Class A (according to ATP) vans (refrigerated trucks) that are mechanically cooled and have standard insulation. FNA vans are designed for transporting goods that require temperatures between 0 and +6°C. Unlike lightly insulated vans, FNA vans have insulated floors, and the van's K-coefficient does not exceed 0.7 W/m²°C.

​

In most countries, FNA vans must be certified. In Estonia, certification is performed by ATP SERT OÜ, and the certificate is issued by the Road Administration. FNA vans are manufactured by Tarfurgo for the Estonian, Latvian, Norwegian, and Finnish markets, and the production of one van takes two weeks.
