The Markel TAT Series Thermal Area Heaters are designed to heat small and mid-sized rooms up to 150F. This provides effective portable heating to areas infected with insects. It kills adult insects and will dehydrate larvae and eggs, making them unable to hatch. Although chemical sprays only target adult insects, they can be used before utilizing the TAT system in order to kill the adult insects.

The system is designed to bring the temperature up to 150F in one hour or less, if all preliminary requirements are met.

The TAT system may be used for water remediation, as well, in combination with adequate ventilation. Specific models for water remediation are also available.

Sizing the TAT System

Sizing formula for Markel TAT Series heaters: 50 Watts of heat per square foot of heated space or 50W/sq ft.
