Introducing BN Thermic Commercial Air Curtains

Introducing the BN Thermic CA Air Curtain Range – The Perfect Mid-Range Solution

Choosing the right air curtain isn’t always straightforward. While compact overdoor heaters are ideal for small shops and cafés, larger commercial air curtains are often designed for department stores, shopping centres and other high-traffic buildings. But what if your project sits somewhere in between? That’s exactly why BN Thermic developed the CA Air Curtain range—a collection of high-performance air curtains that bridge the gap between lightweight overdoor heaters and larger industrial units. Designed specifically for medium-sized commercial premises, the CA range delivers greater air velocity than a traditional overdoor heater while operating significantly more quietly than many heavy-duty commercial air curtains.

Why Air Curtains Matter?

An air curtain creates an invisible barrier across an open doorway, helping to reduce the movement of cold air into a building during winter and limiting the escape of conditioned air throughout the year.

By separating indoor and outdoor environments, air curtains can help:

• Improve customer comfort near entrances.
• Reduce heating energy losses.
• Maintain more consistent indoor temperatures.
• Minimise draughts.
• Help prevent dust, insects and airborne contaminants entering a building.

For businesses with frequently used entrances, an air curtain is often one of the most effective ways to improve comfort without restricting customer access.

Bridging the Gap

For many years, BN Thermic has offered two distinct air curtain solutions. At one end of the range are compact overdoor heaters, ideally suited to smaller retail units, cafés and reception areas. At the other are high-capacity commercial air curtains designed for major retail developments, hotels, office buildings and other large premises. Increasingly, however, customers were asking for something in the middle. They wanted a unit capable of protecting wider entrances and delivering a stronger airflow than a conventional overdoor heater, but without the size, noise levels or specification of a heavy-duty industrial air curtain. The CA range has been developed to meet exactly this requirement.

A Model for Every Application

The CA range offers exceptional flexibility, making it easy to specify the right unit for almost any medium-sized commercial entrance.

The range includes 12 different models, with:

• Heat outputs from 3kW to 13.5kW
• Unit lengths from 600mm to 1.6 metres
• Optional integrated electronic thermostat
• Optional remote controller

Whether heating a single entrance or protecting a larger doorway, there’s a CA model to suit the application. The optional remote controller provides straightforward operation with:

• On/Off control
• High heat
• Low heat
• Fan-only mode for summer operation

The fan-only setting allows the air curtain to continue providing an effective air barrier during warmer months without adding heat to the building.

Ideal for Medium-Sized Commercial Buildings

The CA range is recommended for installation heights between 2.5 and 3.5 metres, making it an excellent choice for:

• Retail stores
• Restaurants
• Cafés
• Garden centres
• Reception areas
• Leisure facilities
• Schools
• Commercial offices

These applications benefit from the CA’s combination of effective doorway protection, quiet operation and flexible control options.

Looking After Larger Projects?

For projects requiring several air curtains, BN Thermic recommends considering the SystemX range. SystemX has been designed for multi-unit installations, allowing groups of compatible air curtains to be controlled from a single location using simple Cat 5 data cabling. This centralised approach offers several important advantages:

• Reduced installation time.
• Less control wiring.
• Simplified commissioning.
• Easier day-to-day operation.
• Consistent performance across multiple entrances.

It’s an ideal solution for larger retail premises, warehouses, office buildings and other commercial developments where several air curtains are required.

Find the Right Air Curtain for Your Project

Every commercial building has different heating and entrance protection requirements, which is why BN Thermic offers a wide range of air curtain solutions. The CA range fills an important gap in the market, providing a quieter, more refined alternative to industrial air curtains while delivering greater performance than conventional overdoor heaters. If you’re specifying heating for a retail unit, restaurant, office or other medium-sized commercial premises, the CA range could be the ideal solution. Our technical team is always happy to help you select the most appropriate air curtain for your application and advise on the best control options for your project.
