Main applications
Liquid heating, hot water circuits, containers and buffer tanks.
These products have been engineered for precision liquid heating. The initial setting of the PID controller, however, is intended for a professional. The best results are obtained in stirred tanks.
They exist in:
- 5 standard power levels: 1kW; 1,5kW; 2kW; 3kW; 4kW
- 2 types of standard fittings: 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.
Thread: 1 “1/4 or 1 1/2" BSPP (ISO 228). Metric thread M45x2 available on request.
Temperature control:
- Electronic temperature controller with double digital display of temperature set point and measured value. This microprocessor controller uses Fuzzy Logic technology. It reaches a predetermined set point more quickly, with minimal overshoot during the disturbances related to the rise or external load.
It regulates with PID action, whose setting is simplified by the auto-tune function that automatically adjusts the parameters P, I and D (A clear User Manual is supplied). If the temperature sensor is broken, the output power is cut off and the error is displayed.
- Temperature display Accuracy: 0.2% of full scale.
- Temperature sensor: Pt100
- Display is configurable in degree or tenth of a degree.
- The two high or low alarm outputs can be set over the entire range of adjustment and have an adjustable differential.
Enclosure: Extremely robust, in thick PA66, designed for outdoor installation, IP65 and IK10. It also includes:
- A fuse to protect internal circuits.
- An illuminated on- off switch
- 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
- On the rear side is located an aluminum housing with cooling fins for a built in 25A SSR.
In models with failsafe manual reset limiter, reset can be accessed after opening the window.
Cable glands: Located on a removable mounting board, providing easier access for connections, fitted with one M25,
PA66, and one more hole for M25, closed by a plastic cap.
Thermowell: In standard, one thermowell in AISI304, dia. 10mm, 135mm length.
Electric connections:
- Built-in terminal block, with 5 terminals 6mm² and 5 terminals 2.5mm².
This terminal block is provided with a strap between terminals 1 and 2. By removing this strap, it is possible to connect an additional safety device, a remote control, or a timer.
- Auxiliary high alarm and low alarm contacts (3A 250V max.)
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 only.
Standard options:
Manual reset limiter, preset at: 60°C, 80°C, 100°C, 110°C, 130°C. (140°F, 176°F, 212°F, 230°F, 266°F)
