Radiants / Heat Diffusers
Heat diffusers / radiants (lava rock) should critically provide even heat distribution across the grill, be self-cleaning and easy to remove. The familiar flavour produced by charcoal grilling comes from the juices of the food dripping onto the hot lava rock. Gas grills use several materials to produce the same effect.
White Lava Rock
White lava rock heats quickly and disperses the heat to the interior of the grill. Due to its smoother surface white lava rock collects less residue and produces fewer flare-ups. The uniform size ensures even heat distribution for better cooking performance. The stones can be cleaned by turning them over to burn off any residue.
Red Lava Rock
Red lava rock also heats quickly and disperses the heat to the interior of the grill. Red lava rock is more porous and allows grease to accumulate, however this lessens its efficiency and increases the possibility of flare-ups. Both types of lava rock should be replaced regularly, or turned over to expose a fresh surface.
The white and red lava can be packaged according to customers individual needs, the standard being 2 x 4.5kg bags per carton.
