These immersions heaters are the smallest with 3 heating elements and aluminum enclosure. There is not enough room inside for thermostat.
They do not have a built-in connection block.
They exist in:
- 6 standard power levels: 1kW – 1.5kW - 2kW - 3kW - 4kW - 6kW.
- 3 types of standard fittings: 1"1/4, 1"1/2 and M45x2
- 2 types of surface load density: 5W/cm² and 10W/cm². See technical introduction to optimize the surface load.
Heater tube material: 8mm dia. AISI 304 or Incolloy 800 (AISI 316; AISI 321; Incolloy 825 on request).
Fitting material: brass, swiveling on housing, brazed on tubes. (AISI 304 or AISI 316, TIG welded, or brazed, models are available on request). Supplied without gasket and without nut. See accessories below.
