Main applications: Heat transfer oil heating on oil filled radiators, and general water or liquids heating when the space available is reduced.

-3 surface load values: 2.5 W/cm², 5W/cm², 10W/cm². See technical introduction to optimize the surface load.

Heating tube material: Element diameter 10 mm, AISI 304 (AISI 316, AISI 321; Incolloy 800, 825 on request).

Insulation: Magnesia compressed by lamination guaranteeing good heat transfer and allows loads up to 20W / cm².

Fitting Material: Crimped 304 stainless steel, with gasket seat.

Thread: 1″ BSPP. This thread allows mounting on standardized central heating radiators. Other side of this fitting is a 1/2″ BSPP for enclosure mounting.

Connection (2 options):

– 1 mm², Silicone insulated wires, 300V, 300mm length, waterproof by silicone potting.

– 48 x 48 x 50mm plastic enclosure, PA66 black, PG11 cable gland output. Built in 3 x 2.5mm²  screws connection block.

Standard lengths (L1): 250, 380, 580,780, 980 mm.

Not immersed heating zone (L2): 50mm.

Thermostat non-heating zone (L3): 50mm.

Surface load: 2, 5W/cm² (oils), 5W/cm² (heat transfer oils, water without flow), 10W/cm² (circulating water). Other surface loads on request.

Voltage: 220-240V single phase.

Thermostat calibration temperatures:

50 ±5°C (122±9°F), 70 ±5°C (158±9°F), 90 ±5°C (194±9°F), 100 ±5°C (212±9°F), 110 ±5°C (230±9°F).

Options on request (MOQ may apply):

– Other calibration temperature, from 40°C to 150°C (104 to 302°F).

– Types without built-in thermostat.

– Lower tolerances on the calibration temperature.

– Different wire lengths.

– Tube length up to 1.8m (Maximum power 1700W in 230V for models with built in thermostat).

– Other thread.

– Other voltage.

– Built-in thermal cut-out , inside the threaded section (usual set point temperature 144°C) .
