Elstein BSI construction panels are infrared radiation areas, which can be equipped with the ceramic IR panel radiators HTS or HSR.

The ceramic infrared panel radiators are fixed to the MBO mounting sheets and surrounded with a housing of frame and capping sections.

All housing parts consist of stainless steel so that radiators with high power can be used, too.

The BSI construction panels are factory assembled so that the user only has to do the wiring, insert the BSI panel in a steel section frame to be made on site and connect the panel with the electricity mains.

Elstein BSI construction panels are available in dimensions from 125 x 250 mm to 1000 x 1500 mm and can be fitted with HTS radiators up to 800 W or rather with HSR radiators up to 1000 W.

Standard scope of delivery (variants available on request)

Ceramic infrared radiators HSR or HTS, T-HTS, fitted
Radiators can be chosen from the radiator power ratings 250 W, 400 W, 600 W and 800 W. The HSR radiators can be fitted also up to 1000 W. Mixed radiator wattages can also be fitted. One thermocouple radiator is provided for each construction panel equipped with HTS.

Frame sections with mounting fishplates and capping sections both made from stainless steel, fitted
These components are used to surround the ceramic infrared radiators fixed to the MBO mounting sheets and to hang the BSI construction panel into a steel section frame to be built on site.

AK bipolar terminal clamps, fitted and connected with radiator power leads
For the electrical wiring of the individual radiators in connection with heat resistant insulated nickel wires and connection of the thermocouple radiator with the heat resistant insulated thermo line.

Mounting units, enclosed, individual parts are not fitted
A mounting unit contains an angle section, up to 3 heat resistant flexible metal hoses with a length of 1m and screw fitting accessories. The hoses are used to hold the nickel wire and thermo line and to protect them from mechanical stress. The mounting units can be fixed to anywhere on the BSI frame section.

Wiring material (nickel wire, thermo line), enclosed
Nickel wire (2.5 mm², max. 500 °C, max. 11 A) is supplied for the electrical wiring of the ceramic infrared radiators. The thermo line (1 mm², max. 400 °C) is used to connect the thermocouple to the controller. The Elstein product range includes a compensating line (1 mm², max. 100 °C) for extending this connection outside the IR radiation area.

Further information and safety information are given in the technical explanations of this brochure. The BSI mounting instruction also includes safety information as well as further details about the installation and the electrical connection.
