When the external temperature outside the bin exceeds 140°F (60°C), an optional heat tube can be added to distance the electronics of a rotary unit away from a heat source. Heat tubes can also be used to extend the rotary beyond insulation on the outside of the bin. For top or side mounted applications with either the BMRX or MAXIMA+, heat tubes are available in 6", 8”, or 12” lengths in either aluminum or stainless steel.
