Sigma Convectors are available in a number of cabinet styles to suit any building interior. Convectors can be specified as slope top, flat top, fully or semi-recessed. In addition, all styles are available as either above-floor mount or as floor-mounted units with either full inlet grille or with arched inlet. Cabinets match industry-standard dimensions in height and in length. All models are available as standard from 16" to 72" in length. Units may be ordered with virtually any combination of depth, height and length, upon request.
