Extra short Immersion heaters with 182mm x 130mm x 224mm
aluminum-plastic of full aluminum enclosure, with 80mm offset. 2"1/2 and M77x2 fittings. With mechanical thermostat. With or without manual reset thermostat.
Power up to 9kw with built-in power relay. Coiled heating elements dia. 8 mm.
Types 9SWN
Main applications: Industrial liquid heating, hot water circuits, containers and buffer tanks. in applications where the heating elements immersed length must be as short as possible.
These heaters with aluminum enclosure are designed for industrial applications of medium power in three-phase, which require the use of contactor. They can receive one power relay, 3 poles 32A resistive. They exist only with thermostat temperature control. The enclosure lid may be transparent polycarbonate or aluminum. They are equipped with a device that allows adjusting the enclosure position after tightening of the fitting.
The enclosure has a 80mm offset to go throw thick thermal insulation.
-5 standard power levels: 1.5 kW; 3 kW; 4.5 kW; 6 kW; 9kW. On request, it is possible to reach 21kWby increasing the L length)
-2 types of standard fittings: 2"1/2; M77x2.
-2 types of surface load density: 5W/cm² and 10W/cm². See technical introduction to optimize the surface load.
Heater tube material: 3 heating elements, dia.10mm or 12mm, AISI 304 or Incolloy 800 (AISI 316; AISI 321; Incolloy 825 on request).
Fitting material: brass, swiveling on housing, brazed on tubes. Supplied without gasket and without nut. See accessories below.
Thread:2"1/2, or M77x2
Temperature control: Mechanical thermostat, temperature range 30-90°C (85-195°F). Other ranges available.
Enclosure: Extremely robust,die-cast aluminum, 3mm wall thickness. Silicone foam gasket. Stainless steel cover screws with locking nuts. Gray epoxy paint RAL7035. Protected against galvanic corrosion. Designed for outdoor installation, IP65 and IK10. It also includes:
- A fuse to protect internal circuits
- An illuminated on- off switch
-A pilot light for power supply and a pilot light for power output.
There is 2 models of cover:
- A PA66 cover with a polycarbonate transparent window allowing access to the settings. This window can be secured with seals. This case also includes a separate lid, with independent seals, providing access to electrical connections. In models with failsafe manual reset limiter, reset can be accessed after opening the window.
-An aluminum cover. This model provides access to settings only after removing the cover. It is convenient for industrial applications that do not request frequent changes in settings.
Cable glands:One M25, PA66, and one more hole for M25, closed by a plastic cap.
Thermowell: two thermowells in AISI304, dia.10 mm x 8.4mm .
Heating elements connections: terminals with stainless steel screw, nut and stainless steel washer.
Three-phase models are equipped with straps for switching to single-phase supply. This change must be made by the professional technical staff able to calculate and observe the maximum permissible rating on power relay.
Power supply connection: on built in connection block,6x10mm² for power connection and 2x2.5mm² for remote safety device or remote control
Not heating immersed zone: 50mm.
Surface load: Standard 5 W/cm² or 10 W/cm², others values on request.
Voltage: Single pole 230V or three phase 380-400V (Star connection with neutral).
Standard equipment:
- Thermostat with knob access under the lid
-Main power switch, with access under the lid
- Green and red pilot lights,, with access under the lid
- On models with manual reset: preset at 100°C (212°F). Reset access under the lid.
