Grimwood Heating  has extended its IECEx certification to now include potentially explosive atmospheres containing hydrogen on its 1750-6S flameproof enclosure.

Electrical equipment for hazardous areas must comply with the requirements of AS/NZS 60079.0 and Grimwood Heating holds a number of IECEx Certificates of Conformity allowing users to meet these requirements.

Hydrogen has similar maximum explosive pressures to other commonly encountered gases, but the rate of explosive pressure growth with hydrogen is approximately seventeen and a half times greater than that of methane.

This means that equipment for use in areas where hydrogen may be encountered must be separately certified as complying with these special circumstances.

It is the responsibility of the occupier of premises to ensure that an experienced person determines the classification of a hazardous area and selects apparatus in accordance with the appropriate standard.

The design of electric heaters to operate in hazardous areas requires an in depth understanding of the process conditions to adequately model the heat transfer within the heater and to ensure compliance with the associated pressure vessel Standards.

The Grimwood Heating range of flanged immersion heaters for hazardous areas includes power ratings from a few kilowatts up to a megawatt, pressure ratings up to ANSI Class 2500 flanges and operating temperatures over 400°C.

High temperature heaters have the enclosure stood-off the flange, and can be fitted with radiation shields. With distributors in every state, Grimwood Heating IECEx certified hazardous area products are easily accessible for every industry requiring a quality solution to their application.
