Berner International Door Heaters

Berner Door Heater

Heating loss has always been a problem when shipping and receiving doors are frequently opened and closed. The infiltration of cold air makes it difficult to maintain a comfortable working environment.

Berner Direct Gas Fired Door Heater’s are the economical solution to this problem. A duct axial fan directs a high velocity stream of heated air towards the door opening. The hot air mixes with the incoming cold air providing a warm comfortable environment.

The door heater is activated through a limit switch. When the door is opened there is a brief pre-purge and safety function check. The fan starts, directing a high velocity stream of hot air that heats the incoming cold air.

Engineered for versatility the door heater can be mounted at any angle between horizontal and vertical to satisfy most applications. All heaters are factory assembled and shipped ready for connection to electric power and natural gas supplies.

Berner Air Curtains – Commercial Entrance Air Doors


Berner Air Doors

Commercial Entrance Air Doors are becoming widely used in building entrances to reduce energy consumption and provide comfort. In the winter, they retain warm inside air and prevent the influx of cold air. They can also supply additional heat in the door area using optional electric, steam, or hot water heaters. In the summer, air doors keep hot humid air out and prevent the escape of air conditioning. The working principle of Commercial Entrance air doors is to provide the most effective air screen possible without blowing so hard that it is objectionable to people passing through.

Air doors are ideal for application on high-traffic doorways in commercial establishments such as stores, restaurants, and banks, and in public buildings such as hospitals, terminals, and schools. In many cases, where a vestibule was installed or planned to reduce the inflow of outside air, an air door is a better approach. This is particularly true for high-traffic entrances where both doors are frequently open at the same time, defeating the purpose of the vestibule. A continuously operating air door allows the vestibule to be dispensed with, resulting in large savings-both in initial cost and operating cost-and increasing the usable floor area.

In addition to providing comfort through the elimination of cold drafts and the addition of heat to door areas, Commercial Entrance air doors have many other benefits. For example, they can decrease door maintenance costs since doors need to be opened and closed less often. In restaurants, they stop uncomfortable cold drafts at customers’ feet. Many schools purchase air doors to save energy and find that as an additional benefit they keep floors dry and safe and hallways warm during winter months. In buildings with high ceilings, the air door recirculates the warm stratified air that rises to the ceiling.

Commercial Entrance air doors are quiet and compact and pay for themselves in a very short time. Most units may be used all year round, and are adjustable for seasonal conditions using a multi-speed motor.

Berner Air Curtains: A Viable Alternative to Vestibules

Berner Air Curtains: An Alternative to Vestibules

Not all buildings have room for vestibules. Not all owners want a vestibule, and there are spaces where a vestibule is just not practical or takes away from the design intent.

As part of our response to the Design and Construction Community asking for information and data to support using an air curtain in place of or along with a vestibule, we did two things:

  1. We researched air curtain (a.k.a. “air door”) effectiveness via both CFD modeling and physical testing,
  2. We went to AMCA (Air Movement & Control Association) and asked AMCA to do its own research on air curtain effectiveness on behalf of all the air curtain manufacturers.

Here is the Berner infographic summarizing the results. Please click on the link below to view the full size PDF version.
