OnatexHeat is designed and manufactured to comply with ATEX-directive – since 2005

Ontec Oy’s ATEX quality system and product manufacturing have once again passed the assessment.

OnatexHeat is a control system for trace heating for potentially explosive areas. It provides full product temperature control in industrial pipelines. The system can be used for trace heating control in both normal facilities, as well as potentially explosive atmospheres. As a manufacturer we are responsible that our products comply the safety requirements by removing ignition sources and minimizing the consequences of possible explosions.

ATEX, 2014/34/EU

The ATEX Directive 2014/34/EU covers equipment and protective systems intended for use in potentially explosive atmospheres. These equipment’s and systems must be manufactured to comply the requirements and conformity assessment procedures of the directive.

Potentially explosive atmosphere

Potentially explosive atmospheres can be caused by flammable gases, mists, vapours, or dust creating a mixture with air. These atmospheres are classified into different zones by the employer.

The classification given to a particular zone, and its size and location, depends on the likelihood of an explosive atmosphere occurring and its persistence if it does.

Potentially explosive atmospheres primarily occur when handling flammable liquids and gases, and dusts, in the processing industry and distribution substations, for example.

Compliance and classification of products

The classification of product category must be defined by the manufacturer based in its purpose of use. ATEX directive divides equipment into two groups based on where the equipment is used and these groups are divided into equipment categories.
In addition to product requirements, the Directive on ATEX equipment creates a number of obligations for the manufacturer of the product.

CE marking

The CE marking indicates that the manufacturer or authorised representative of the product guarantees that the product conforms to the essential requirements set out in the applicable EU directives and regulations.

In addition to the CE marking, products must also include other markings required by the Directive, such as traceability requirements, year of manufacture and the special marking for explosion protection, including the Ex-symbol and markings indicating the equipment’s group, equipment category and intended operating environment. Furthermore, they must also be marked with all information essential to their safe use.
