Main applications
Liquid heating, hot water circuits, containers and buffer tanks.
These all stainless steel construction immersion heaters, are intended for scientific, medical, or corrosive environments. All welding are TIG, without brazing alloys. They are achievable in 304 or 316 stainless steel.
They exist in:
- 6 standard power levels: 1kW – 1.5kW - 2kW - 3kW - 4kW - 6kW.
- 2 types of fittings: 1"1/2 or 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: AISI 304 or AISI 316, TIG welded, swiveling on housing. Supplied without gasket and without nut. See accessories in the datasheet.
Thread: 1"1/2BSPP (ISO 228)
Temperature control: single pole or 3 pole thermostat, 30-90°C (85-195°F). Other temperature ranges in option.
Enclosure: 105 × 105 × 100mm, 304 or 316 stainless steel enclosure, 1mm wall thickness. Silicone gasket. Stainless steel cover screws, 2 internal earth terminals M4;
Ingress protection class: Water and dust: IP65; shock resistance: IK 10 (with metal cable glands and M25 metal plug).
Cable glands: M25, PA66. Nickel-plated brass or stainless steel on request.
Thermowell: in standard on thermowell in AISI304, dia.8 × 7mm, also for models supplied without thermostat.
Electrical connections: tubular heater terminals with stainless steel screw, nut and stainless steel washer. Switching straps on 3 phases models.
Models with thermostats have a 6 × 2.5mm² built-in connection block. Two M4 grounding terminals.
Support grid: 1 grid AISI 304 for lengths from 400 to 600mm, 2 grids above.
Not heating immersed zone: 50mm.
Surface load: standard 5W/cm² or 10W/cm², other values on request.
Voltage: 220-240V single phase or three phases 380-400V (Star connection with neutral)
Standard options:
- 230V single phase thermostat for power up to 3kW. 3 phases thermostat for 4kW and 6kW models.
Variants on request:
- External thermostat knob, with waterproof shaft gasket.
- 4-40°C (40-105°F), 0-60°C (32-140°F), or 30-110°C (86-230°F) thermostat.
- It is possible to deliver these devices with one or two pilot lights and a power cord.
