UHIR Series Unit Heater Overview
ZIRCO distributes INDEECO UHIR Series Unit Heaters as the official Canada representative. These versatile unit heaters offer a comprehensive range of options designed to meet the heating needs of diverse commercial and industrial environments. With 50 standard models available in capacities up to 50 kW, the UHIR provides powerful and reliable heating tailored to your specific space requirements.
Designed to operate efficiently at multiple voltages—208, 240, 277, and 480 VAC—in both single- and three-phase configurations, the UHIR delivers versatility and adaptability to suit various electrical systems and facility demands. The innovative draw-thru airflow design pulls air across the heating elements, ensuring cool element operation and even air distribution for extended element life.
Universal horizontal or vertical discharge mounting provides installation flexibility, while optional diffusers optimize airflow distribution for different mounting heights. Available in standard camel finish with six optional colors or unpainted galvanized steel for corrosion resistance, the UHIR Series integrates seamlessly into any facility aesthetic throughout Western Canada.
