Produkteinführung

This thermal aerosol generator heats a compatible aerosol liquid under controlled conditions, carries the vapor into a cooler region and forms a stable condensation aerosol. Independent temperature and carrier-flow controls allow output to be adjusted for demanding filter systems while maintaining repeatability. Insulated hot surfaces, over-temperature protection and a drainable stainless flow path support safer field use and straightforward maintenance.

Key Features

Controlled heating produces dense aerosol without relying solely on compressed-air atomization.

Separate temperature and carrier-flow settings provide repeatable output adjustment.

Fast thermal response reduces stabilization time after a new setpoint is selected.

Insulated housing and over-temperature shutdown protect operators and internal components.

Stainless liquid path supports cleaning and compatible test-liquid changeover.

High-output configuration suits large air-handling units and demanding filter banks.

Kunden Produktbedenken

Thermal aerosol generation requires stable heat transfer, safe handling and controlled output across changing filter-system demands.

Heating can degrade test liquid or change output if temperature drifts.Closed-loop temperature control and a defined operating range stabilize vaporization without unnecessary overheating.

Hot external surfaces present a handling risk during field testing.Thermal insulation, guarded surfaces and cool-touch handles separate the operator from the heated core.

Condensed residue may accumulate in the outlet after shutdown.A controlled purge and drainable stainless path clear residual vapor before storage.

Large concentration changes can overload downstream measurement equipment.Independent carrier-flow and temperature settings allow output to be increased gradually to the required challenge level.
