Dimplex is a trusted name in electric heating and home comfort, known for combining proven reliability with energy-efficient innovation across a wide range of residential and commercial solutions.
Overview
The Dimplex Air Curtain Warm Air 3 kW (AC3N) is a high-performance over-door heater purpose-built for commercial and small-entrance applications. Whether mounted above shop doors, office entrances, or similar apertures, it delivers a consistent curtain of warm air—promoting an inviting environment while reducing heat loss. Not intended for full-room heating, its core strength lies in localized, directional warmth that keeps doors “open for business” with comfort and efficiency.
Efficient, Warm Welcome
Strategically positioned above entrances, the AC3N creates a thermal barrier that encourages customer flow and comfort.
Modern, Curved Design
Its subtle curved styling complements contemporary interiors while ensuring unobtrusive integration above single doorways.
Versatile Heat Settings
Choose from Full Heat (3 kW), Half Heat (1.5 kW), or Fan Only modes to manage output and conserve energy.
Adjustable Airflow
A detachable mounting bracket enables wall or ceiling placement and adjustable airflow direction (horizontal/vertical) to suit different space layouts.
Compact and Durable Build
Crafted from pressed steel with a white powder-coated finish, the unit is IP21-rated for indoor use (protection against dripping water and solid objects).
Quiet Operation
With a noise level of approximately 50.5 dB(A), the AC3N maintains a low acoustic footprint—ideal for customer-facing environments.
