AOLQ technician checks fragrance output, oil-path leakage and control functions on a commercial scent diffuser.

Coverage Engineering And Atomization Control

Coverage planning: Start with usable floor area, ceiling height, room divisions, airflow direction and the daily operating schedule. Open lobbies and HVAC-connected zones require a different output strategy from enclosed rooms of the same size.

Atomization and control: Compare model-specific output range, oil consumption, timer or APP control, operating noise and adjustment steps. Confirm these figures from the selected model rather than applying one claim to the whole range.

Installation and service: Check power supply, placement or HVAC connection, refill access and routine atomizer cleaning before sample approval. The recommendation should balance coverage stability with practical maintenance.

Configure Coverage, Control And Installation

Send the usable floor area, ceiling height, room layout, airflow conditions and required operating hours. Identify whether the unit will be standalone, wall-mounted, floor-standing or connected to an HVAC system.

Confirm the preferred control method, acceptable noise, oil capacity, refill frequency and maintenance access. These details allow us to compare coverage and consumption instead of choosing only by machine appearance.

After the functional model and sample are approved, finalize housing color, logo position, labels, accessories and export packaging for the destination market.
