When purchasing explosion-proof electric heaters, a frequently asked question is: why do products bearing the same Ex d ⅡC T6 Gb marking show obvious price differences? The difference usually lies not in shell thickness, but in details such as interlock protection, terminal chamber configuration, and flange type. The BDR-ExD-600 explosion-proof electric heater is designed with these procurement concerns in mind.
This model carries the explosion-proof marking Ex d ⅡC T6 Gb, and its flameproof enclosure is suitable for chemical, petrochemical, and other locations where flammable and explosive gases are present. The connecting flange can be selected as a round flange or a square flange according to the pipeline interface (square flange is indicated by adding F after the model number), facilitating on-site connection. The design pressure is 1.6MPa, the rated voltage can be selected as 220V or 380V, and the power is customized according to the user's operating conditions.
The terminal chamber is an independent flameproof cavity, in which a temperature controller can be installed to reduce the need for an external control cabinet. The cable entry of the chamber is equipped with a flameproof cable entry device, and the terminals are marked by phase sequence, making it easy for purchasers to verify electrical parameters.
When requesting a quotation, it is recommended to specify: medium type and flow rate, inlet and outlet flange specifications, voltage and power, whether in-chamber temperature control is required, and installation orientation. Finalizing the model after confirming the above parameters can reduce situations such as flange mismatch or control mode deviation after delivery. This product belongs to the heating category within the explosion-proof electrical apparatus series and can be optionally configured according to project requirements.
