ستارة هوائية للطرد المركزي

ستارة هوائية بمروحة طرد مركزي لمداخل المباني والفتحات الأكبر.

Overview

The centrifugal air curtain uses a fan-driven discharge to form an air barrier at a building opening. The catalogue describes an external-rotor centrifugal fan arrangement with pressure capability suited to the selected entrance duty and, where specified, an air-heating section.

Heated versions transfer energy from a selected hot-water, steam or electric source into the discharge air. Coil construction is matched to the heat medium, so different thermal arrangements are not interchangeable without a proper equipment selection.

The cabinet can be coordinated with exposed or concealed installation and the intended interior finish. Door dimensions, available heat source, mounting conditions and the required airflow pattern determine the appropriate unit and its position.

PRODUCT DETAILS

Product Features

Centrifugal fan air delivery

The fan arrangement provides the pressure needed for the selected discharge duty. Airflow and pressure are coordinated with the entrance geometry and the resistance of the unit’s treatment sections.

Selected heating arrangement

The catalogue lists hot-water, steam and electric heating possibilities. The available utility, required thermal duty and installation constraints determine the appropriate version.

Heat-medium-matched coil

Copper-tube aluminium-fin or other specified heat-exchanger constructions are selected according to the heating medium and operating conditions. Coil selection is confirmed with the actual supply temperatures or steam duty.

Cabinet finish choices

Painted, electrostatically coated and brushed-stainless cabinet options are described within the range. The selected finish can be coordinated with the room appearance and exposure conditions.

Exposed or concealed installation

Different cabinet arrangements allow the air curtain to work with the entrance design. Clear inlet, discharge and service access remain necessary in either installation form.

Serviceable equipment assembly

Fan, heating and casing access should be maintained after installation. The location should also allow inspection of the selected water, steam or electrical connections.

Thermal columns identify alternative configurations. Electric-heating capacity is separate from fan power. The catalogue describes hot-water, steam and electric heating options; confirm heat source, coil materials, inlet conditions and installation clearances for the ordered model.

WHERE IT WORKS

التطبيقات

The catalogue identifies shopping centres, office buildings, hotels, restaurants, workshops and underground garages. Each opening has different exposure and airflow conditions, so equipment is selected against the actual use rather than the building category alone.

Confirm opening dimensions, mounting position, air duty and the available heat medium. Installation and controls should be coordinated with door use, occupant comfort and maintenance access.
