All Robust-radiator modules are specified with the dimensions in the schematic below. Please read power in the respective tables below.
Why are they long lasting? MHI Robust Radiator is enclosed in a special RR Fractalin Ceramic which displays extraordinarily low expansion or distortion. This is the secret of its longevity. For A, B, C & D Dimensions See Diagram Below
High Uniformity G-Robust Radiators (GRR) for 1250°C/1300°C
Provided with Non-toxic Ceramic Enclosure GRR High Uniformity Robust Radiators may be used to approximately 1300°C. For temperatures higher than 1300°C for the Robust Radiator, please click on Robust Radiators. Please call for Dimensions of GRR. Dimensions are for heated chamber size. Please add about 1″ – 2″ thickness for ceramic shell. The following table provides dimensional guidance only for the heated zone. Use with DC or AC (50/60Hz).

** Plug-in voltage indicates closest IBPAN preference. The GRR unit-temperature, ampearage (current) or power, cannot be exceeded in any configuration of use. Configuration of use changes with end caps, load, flow placement of control thermocouple, and extent of insulation. Please check manual for maximum element temperature that cannot be exceeded.
Some Of Our Many Satisified Customers Using the Robust Radiator
M.O., National Laboratory “…the heating system that you helped me set up is working great!”
“…Robust Radiator is working perfect as a Crucible heater.”
L.C., Canada “We just received the elements… they look great.”
Dave J, Washington “I am very pleased with its performance. We feel it can be useful for a lot of our projects.”
Unlike fully finished furnaces, Robust Radiators™ are products that are typically components of a larger system. Please be fully conversant with the electrical and safety requirements during installation and use, including the use of connectors. Please call MHI at 513-772-0404 when in doubt. Contact MHI for custom solutions.
Inline Robust Radiator
Specifications (Inline is built to specification, minimum order may required)
MHI’s Inline Robust Radiators™ are versatile, high temperature heating devices that are capable of reaching temperatures of up to 1700°C. They can be used in a variety of environments and positions. The MHI Inline Robust Radiator™ is available with optional end caps to achieve maximum chamber temperatures and an optional stainless steel shell that adds to the connection accessibility. You can order by part number or inquire about special needs. MHI will be happy to provide a personalized recommendation that will fit your needs.
Inline modules come with standard ceramic sleeves.
Inline modules with metallic shells are also available
Live Customer Support by phone (513-772-0404) or email. . Typical single and Multi-zone configurations are shown below. Terminal connectors are shown for each-zone. End-caps and all other accessories available – see section on Robust Radiators.

Hemo-dialysis fluid heating
The JOULE (J) is a commonly used unit of energy. The BTU is also an unit of energy. Another typical unit for energy is KWhr (Kilo-Watt-Hour). 1kJ (KiloJoule) = 0.9485 BTU=0.0002778 kWhr
The Watt (W) is a unit for power i.e. the energy used (or supplied) per unit time. 1 J/s (Joule per second) = 1 W (Watt)
Power-Units Conversion 1kW (KiloWatt) = 3414 BTU/hr
How much energy and what kind of power will be suitable for your heating application? The estimators in the link above may be used to calculate the energy required for common processes. Then by choosing a time over which the energy will be used one can calculate the best power required from the heater.
