Norske Backer heating flask type SIH-H/M/L-...Exd with 2'' pipe thread connection, is intended to be an affordable alternative. Therefore, the range of this type of heater has standardized voltages, heat output, insertion lengths and three surface efficiencies (W/cm²). The heater is designed for heating liquids and horizontal installation in tanks, vessels, flow-throughs or pipe systems.
The heater is available for 1/3×230, 3×380, 3×400, 3×440, 3×460, 3×480, 3×660 and 3×690 operating voltage.

| Electrical heat output, minimum - maximum | 1kW with 0.5kW increase to 6kW | |
| Insertion lengths | 200 to 410mm | |
| SIH-M-...Exd: | Surface effect elements | Max. 2.5W/cm² |
| Electrical heat output, minimum - maximum | 1kW, with 1kW increase to 6kW | |
| Insertion lengths | 300 to 1000mm | |
| SIH-L-...Exd: | Surface effect elements | Max. 0.9W/cm² |
| Electrical heat output, minimum - maximum | 750W and 1kW, with 0.5kW increase to 3kW | |
| Insertion lengths | 400mm to 1350mm |
| Media temperature | Max. 100 °C |
| Temperature class: | T4 |
| Ex protection junction box: | Ex d |
We assume that the customer has knowledge of the heat capacity (kJ/kgK) of the fluid in which the heating coil is used, so that the correct surface effect is selected. It is recommended to buy with Socket wrench SW75 and Open wrench SW90 for mounting the heating flask.
