AH-310i Diesel Infrared Heater by Rex Nordic

The AH-310i is a powerful 51,000 BTU diesel-infrared heater designed for larger spaces up to 55,000 cubic feet, making it ideal for warehouses, large workshops, construction sites, and industrial applications. This robust unit operates on renewable diesel (HVO) or standard diesel with a fuel consumption of 0.66 gallons per day during continuous heating, though the automatic thermostat typically reduces actual consumption significantly in real-world use, while its substantial 11.9 gallon fuel tank ensures extended operation for demanding applications.

Advanced smart controls set this heater apart, featuring WiFi connectivity and optional 4G network connection that allows remote operation through the dedicated Rex Nordic mobile app, available on both Android and iOS platforms. The intuitive soft-touch control panel with LED screen provides easy local operation.

Temperature management is precise and flexible, with automatic thermostat control adjustable from 32°F to 104°F, ensuring optimal comfort while maximizing fuel efficiency. Additional convenience features include a programmable stop timer up to 24 hours and an interval timer that cycles between 5-60 minutes of operation with 5-minute breaks.

Despite its substantial 51,000 BTU heating capacity, the AH-310i operates quietly at just 48 dB and requires minimal electrical power at only 80 watts. Measuring 37.4″ W x 12″ D x 39.8″ H and weighing 101 lbs, this heater combines professional-grade performance with practical portability for industrial environments.
