Robust Radiator™ - Radiant Heating Chamber

Stackable (Both Verticle and Horizontal Stacking is Allowed)

MHI's Robust Radiators™ are versatile, high temperature heating components that are capable of reaching temperatures of up to 1700°C. Unlike a high temperature furnace, Robust Radiators™ are more commonly used as components of a larger system.

Robust Radiator™ uses include zone heating, crucible heating, pipe heating or other applications requiring high temperatures and high versatility. Robust Radiators™ are available with optional end caps to achieve higher chamber temperatures above 1400°C.

Robust Radiators™ may be used in vertical or horizontal orientations, allowing for a diverse array of applications. An optional stainless steel shell adds highly accessible terminal connectors to the already robust design.

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.
