Product context
Overview
Airrex AH-300i is a diesel infrared heater for larger working areas, temporary spaces, and event support. It sits above the AH-200i in the launch range and is better suited to bigger covered spaces, event tents, workshops, halls, terraces, and warehouse areas.
The product uses infrared heat, so it is useful where direct warmth is needed in a defined area rather than relying only on warm air circulation. It can support temporary structures and operational spaces where the heating plan needs to account for doors, wind exposure, ventilation, and footfall.
Before quoting, Temporium should capture the dimensions of the space, approximate volume, fabric or wall type, openings, expected outside temperature, operating hours, fuel storage route, supervision plan, and whether the site requires certification or risk assessment documents.
Final UK pricing, stock, warranty route, packed weight, pallet requirement, and safety documents should be confirmed before order. For launch, keep this product quote-led until manufacturer documentation and delivery rules are complete.
