Chalmit have recently completed a redesign project on the Sterling range of products, primarily on the Exn Zone 2 version but also on the industrial version.
These changes have been brought about by updates in the IEC 60079-15 standard covering equipment used in Zone 2 areas. Chalmit have also taken advantage of new developments in the design of high frequency ballasts. The following changes have been introduced into our Sterling II product range: Zone 2 Version 1. A new stronger enclosure (diffuser and body). 2. A new custom made high frequency ballast which meets the requirements of IEC 60079-15, without the need for secondary protection. Although not a requirement of the Zone 2 standard, this ballast also has EOL protection circuitry built in which complies with the Exe standard IEC 60079-7. Our original ballast in the Exn Sterling was an industrial HF ballast housed in an aluminium extrusion. 3. For the emergency version we have also introduced a new inverter. This inverter is encapsulated in resin and will be less susceptible to problems when installed in areas of high temperature.
Industrial Version 1. The same new enclosure introduced into the Zone 2 range. 2. A more robust industrial ballast with universal voltage from 110 to 254V. This will give better protection against high and low voltage fluctuations.
These changes have been introduced to bring the Sterling product range up to the very latest standards and also to improve the reliability of the product.
