MHI URP Heating Panel Specifications
Product Overview
The MHI URP Heating Panel is a universal, scalable radiant heating panel designed for high-temperature furnace and thermal processing applications.
Each panel utilizes proprietary GAXP flat heating coils and Fractalin ceramic spacers, securely mounted on a thermal shock-resistant insulation slab. The panel is intended as a modular building block for furnace systems.
Important Safety Notice:
Furnace enclosures should only be designed and assembled by qualified personnel and with approval from a licensed electrician. These panels operate at high current and can reach extremely high temperatures.
Operating Characteristics
- Nominal Power per Panel: ~1.8 kW
- Maximum Coil Temperature: 1200°C–1400°C
- Recommended Maximum Coil Temperature: 1350°C
- Measured with a two-color optical pyrometer
- Orientation: Horizontal use only
- For vertical applications, select the URP-V Vertical Panel
- Two electrical terminals are located beneath the ceramic board (not shown).
Electrical Specifications

Four panels may be connected in series for a 220-240V plug-in configuration. Balanced series-parallel connections may be used (purple and red in the picture). All measurements are reported in the free radiating mode. 
For layout possibilities, please see diagram alongside.
L1 = 12″
L2 = 12″
L3 = 9.5″https://mhi-inc.com/contact-us-request-information-about-mhi-products-or-for-general-inquiries/
L4 = 10″
T= 1.125″ (thickness of thermal shock-resistant insulation slab below the heater coil).
Lu = 7″ (Terminal Length). The terminals protrude about 6″ from the bottom of the insulation board (on the other side of the heating face). Use may request shorter Lu with quantity purchase.
Options:
The connectors comprise clip-type connectors (used to connect the wire and solid terminal) and two wires. One set, when chosen from the options menu comprises two clips and two wires i.e one for each lead. The rating of the connectors is 35 amp wire carrying capacity. Dimension – 6″ wire.
If required to extend beyond the 6″ standard, please contact MHI, and we will happily accommodate the request as best as possible.
The weight will be calculated with the control panel option when checking out.
The correct weight and shipping price will be shown in the final acknowledgment from MHI.
