Description
MHI MC-GAXP-130-V Spiral Microheater For Vertical or Upside-down use Use.
For the “V” vertical modules the spiral is potted- held by FractalGlue™ (Alumina). Shown in the gallery pictures below the main picture.
1200-1250C (OD=2″) Maximum temperature of element in vertical configuration.
Ceramic Base and End Connectors Included.
Approximately 700 Watts [26V @ 27A (RMS)].
** Power reported under free radiating/ no-load condition with heater resting on provided ceramic plate.
Connectors comprise of One set of appropriately rated connecting clips and 5 to 8″ braided wire.
Note that the maximum current/power will be different (lower) if covered. Please do not exceed limits of current, voltage or element temperature.
For more information please visit our GAXP Spiral Microheaters page
For controls choose either
Feedback controls namely BPAN-O-PLUS and Transformer. For customers who do not have a 120V wall supply, a 220V to 120V transformer will be added at no extra cost.
or
Open Controls with no feedback i.e. the DC Power Supply and a TC Read
Please choose BPAN-O-PLUS-220 when more than 3 units of the 2″ Spirals are placed in series
Only the BPAN-O-PLUS 120T (120V) option should be chosen when a single 2″ unit is used. MHI will confirm the order with the correct panel so there is no need to be concerned if a wrong panel is chosen during the order.
For more information on the BPAN-O-PLUS controller please click to the Power and Temperature Control Panel Pages.
Alumina ceramic is rated to 1800C.
When checking out, the weight will be calculated with the control panel option.
The correct weight and shipping price will be shown in the final acknowledgement from MHI.
Note that the maximum temperature is at the center of the spiral region unless asymmetric power delivery is required
In the diagram in the specifications tab D1 and D2 are separated by 0.1″ T is 0.25″ and H is 2.5″. D1 is the OD.
For obtaining maximum temperature MHI controls are highly recommended. Large diameter GAXP® microheaters could develop some springiness from induced magnetic forces. Potting in ceramic paste is allowed as long as care is taken to factor-in the loss of any thermocouple response in the measured temperature. Note element temperature will be higher and maximum element temperature should not be exceeded. In the free radiation mode the power can be maximized.
The objective of the use for free radiating devices is to maximize the radiative POWER transfer from the heating elements. If the heating element is covered with insulation, the objective of the user changes to obtain a certain temperature inside the insulated region. The control of temperature inside a chamber, or power maximization in a free radiating mode can be made with MHI temperature and/or power controllers. When covered the power and current will be lower and the element temperature can be exceeded quickly if not monitored and controlled. For either objective, one cannot exceed the rated temperature or maximum current of the heating element. Power output will be lower in enclosed radiation mode with a temperature control feature as opposed to or in addition to the power control.

“We have used the heater, it is working well. Do you have calibration chart (Temperature v/s Voltage) for this MC170 microheater. ……………..Since we do not have temperature measuring tool for such a high temperature (1900C)…………..We are planing to order one more heater………………….”

Professor A. R., Academician, Ukraine
Several years ago we have bought in your company the front loading M18-40 furnace and two robust radiators and got much satisfaction working with them. Now, we believe, it is a very time to substitute heating elements in the furnace and to buy new radiators.
