product presentation

Main applications: Heating of liquids, hot water circuits, containers and buffer tanks. They provide significant power to heat liquids when the available depth is limited.

They exist in standard in 3 types of surface load density: 2W/cm², 5W/cm² and 10W/cm². The 2W / cm² load is recommended for heating viscous products such as oils and fats. (Others available on request). See the technical introduction to select the best surface load.

Many enclosures for these heaters are available in our catalogue N°11.

Heater tube material: 8mm dia. in AISI 304 or Incolloy 800 (AISI 316; AISI 321; Incolloy 825 on request). Fitting material: Brass, brazed on tubes. Supplied without gasket and without nut. See accessories below. These fittings have M4 threaded holes for connection box assembly
Thread: 2”1/2 BSPP (ISO 228); M77x2.

Thermowell: Dia. 7x8mm, using the same material than heating elements.

Heating elements connections: Stainless steel M4 screw terminals, nuts and washers Ground connection: M4 threaded hole
Not heating immersed zone: 60mm including the length inside the fitting.

Surface load: Standard 2W/cm², 5 W/cm² or 10 W/cm², others values on request.

Voltage: 230-240V single phase (110-115V and 380-400V on request)
Option: Set of 4 brass jumpers for star-triangle commutation in 3 phases or connection of 3 heating elements in parallel.
