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).
