The Sealey ABI600 is an indirect fired kerosene and diesel space heater delivering 20kW (68,000Btu/hr) of clean, fume-free heat for workshops, warehouses, construction sites, marquees and events. Unlike direct heaters, this indirect fired model exhausts all combustion by-products through the top-mounted flue system, making it ideal for enclosed spaces with limited ventilation or where personnel are working. With a substantial 38-litre fuel tank providing up to 19 hours runtime and a 600m³/hr airflow, the ABI600 effectively heats areas up to 150-200m². The integrated thermostat control automatically maintains your desired ambient temperature by cycling the heater on and off, optimising fuel consumption whilst ensuring consistent warmth throughout your workspace. Built to professional standards, the unit features a stainless steel combustion chamber with fan cooling, Danfoss pump, and electronic flame control system for reliable operation. Safety is prioritised with a built-in flame sensor and automatic flame-out device that cuts fuel supply if the flame extinguishes or fuel runs out. The IPX4 rating provides splash protection, whilst large transport wheels and carry handle ensure easy repositioning around site. Compatible with optional ducting (ABI1000AK1) and flue systems with rain covers (ABI1000AK2/3/4) for enhanced versatility.
