The casing is manufactured from 1.2mm zintec steel sheet and will have a matt black powder paint finish to the inside face. Levelling bolts are fitted through the base of the casing to allow up to 20mm height adjustment if required.

A single module is 1200mm long producing 550 watts per unit. Where casings are required to form continuous runs we provide fixings so that several units can be joined together, along with ‘dummy’ sections to make up the exact length required. There are 20mm cable entry holes at each end allowing continuous feed of power supply to run through in the air intake chamber. Provision of earth continuity link between casings is also allowed for.

Where casings are supplied as individual units the grille and frame are factory fitted.

Heating elements are of steel hairpin construction and have steel fins bronze welded to the core, this construction offers excellent heat transfer and an even temperature along the active length, the elements have a 50mm cold zone at the connection end and are fitted into a wiring control box using gland nut and shake proof washers.

Within the casing there are two high temperature limit stats fitted to the splitter plate, which are fitted centrally in each half of the casing. In the event of the casing grille being partly covered by a carpet, clothing or similar preventing the air circulating through the casing thus causing the temperature to rise above the desired maximum, the heating will be switched off until the cause of the temperature rise has been investigated by a competent person and rectified, the stat can then be manually re-set by pressing the reset button “other types of stats can be employed if required”, there are safety shields fitted over the stats to prevent liquids which may be split into the casing coming directly into contact with the stat wiring terminals.

There is a wire safety mesh fitted over the entire heating chamber to prevent the ingress of items which may be dropped through the grille, the mesh is 96% free area which allows maximum air flow through the unit.

Above the mesh there is an aluminium grille frame into which a “70% free area” cross bladed flexible grille is fitted, both grille and frame have a durable silver satin anodised finish.
