The Internal Radiant Infrared Modules with Fast Medium Wave Lamp in the MI-2500XL / MI-4500XL / MI-4000 models represent a professional evolution in the sector of infrared heaters for industrial processes , designed to be mechanically integrated inside operating machines, ensuring rapid, uniform and controlled heat transfer.
These modules are ideal for complex applications that require precision, operational continuity and maximum reliability such as IR tunnels, industrial ovens, professional dryers and high-performance drying systems .
The structure with interchangeable monoblock reflective body and the reflector in polished aluminium treated with electro-brightening and continuously polished Grado Specular Tex with very high reflective power allow for optimised heat diffusion.

Entirely made in Italy and hand-assembled, these infrared modules are equipped with a fast, medium-wave translucent quartz IR lamp , equipped with special high-temperature-resistant nickel/copper cables with Teflon insulation. The terminal block housed in a metal box protects the entire system and ensures electrical continuity even under harsh operating conditions.
All models have IP24 protection rating , a feature that allows safe use in controlled industrial environments.
These internal infrared modules feature optimized symmetrical diffusion with a high reflection coefficient. The standard optics are supplied with a diffusing focal length ( a concentrating optic is available upon request for high energy density applications).
The hot-dip galvanized sheet metal construction guarantees mechanical resistance and durability ( AISI 316 stainless steel is available upon request for highly corrosive environments). Each unit is designed, built, and assembled entirely in Italy and ROA certified according to Legislative Decree 81/08 and Directive 2006/25/EC .

These types of infrared waves have a greater heat diffusion capacity , ensuring uniform, intense, and comfortable heat distribution. This phenomenon is attributable to the wave's limited penetration into the air and maintains the heat even after switching off. Fast medium waves are the most widely used in industrial settings due to their better power/heat distribution ratio .
Medium wave quartz lamps can reach operating temperature in about 40 seconds . Furthermore, fast medium infrared waves emit very little visible light , and the bulb temperature can reach 500°C.
The design, construction, and manual assembly, performed entirely in Italy, ensure high-quality construction and control over every stage of production. This artisanal care makes the heaters reliable, high-performance, and suitable for intensive industrial use in continuous work cycles.
The Specular Tex® electro-polished aluminum reflector amplifies the lamp's radiant power, improving the quality of radiation and optimizing consumption . The surface with an extremely high reflection index allows for even heat distribution, reducing dispersion and increasing the effectiveness of heat treatment operations.
The optimized symmetric diffusion allows uniform irradiation across the entire work area, reducing thermal gradients and optimizing the quality of treatment on materials such as technopolymers, fabrics, metals, leathers, plastics and microgranules.
The standard diffusing optic is designed for most industrial uses.
The hot-dip galvanized sheet metal construction ( optional AISI 316 stainless steel available upon request ) ensures durability and protection against the chemical and environmental agents typical of the most demanding production environments. Entirely Italian assembly guarantees artisanal quality combined with high industrial standards.
