Door Sentry Alarm For Cold Room Doors

When your business is investing in a temperature-controlled solution, having the perfect cold room door is essential to ensure your day-to-day processes run smoothly AND that your cold room maintains the temperatures required.

Cold room doors are not only vital access and egress points for your cold room or storage area, but they are also essential to maintaining the internal temperatures of your walk-in chiller or freezer.

Chiller and freezer cold room doors being left open for longer than necessary is a continual source of wasted energy. But, how can you combat this? With a Door Sentry alarm system.

Allowing your cold room door to remain open lets warm air enter your temperature-controlled room – meaning that your walk-in cold room now requires additional cooling (by the refrigeration unit working harder) to return to its required temperature.

If your external temperatures are high, then it will have a greater impact on your walk-in chiller or freezer cold room when your cold room door is open.

One way to prevent this from happening is with the help of a Door Sentry alarm system.

What Is A Door Sentry Alarm System?

A door sentry alarm system is an audible alarm for your chiller and freezer sliding or hinged cold room doors. The alarm will sound when your cold room door is left in the open position for periods of time – this audio message can be customised to your requirements, along with volume/time being adjusted to suit.

Once your cold room door has been closed, the inductive and infra-red sensors will alert the alarm to stop.

Excessive opening of your cold room doors can lead to a build-up of ice in your cold room and around the outside – reducing your cold room efficiency drastically and putting your products at risk, especially if they’re food products.

Benefits of a Door Sentry Alarm

There are various benefits to a door sentry alarm system. Some of these are outlined below:

• Good Cold Room Door Policy
  The alarm will prompt and remind your employees to ensure they are closing the cold room door regularly, hopefully instilling a memorable and good cold room door policy and routine. With its loud audio messages, your employees are certain to close the door as soon as possible.
• Energy Efficiency
  Testing has shown that implementing a Door Sentry Alarm can help save up to 17% of your walk-in chiller or walk-in freezer energy costs. Although not an immediate saving from the alarm system, the Door Sentry will in turn reduce your energy consumption levels because you are minimising the amount of time the door is open for – therefore reducing the amount of extra work your refrigeration unit will have to put in.
• Reduce Cold Room Maintenance and Call Outs
  Not only will the door sentry alarm reduce the amount of time your cold room door is open for, but it will also reduce the amount and frequency of maintenance issues and call outs you experience. This is because the less time your door is open for, the less of a chance it has to prompt ice build-up or cold room efficiency problems.
• Protect Product Quality
  You put your products and their quality at risk when your cold room door isn’t shut regularly or allows external air to combine with the temperature-controlled air. This could quickly become dangerous for your business, especially if you rely solely on your refrigerated products to make profits. Not only this, but certain foods must be kept at specific temperatures constantly. For example, dairy and meat products are high-risk foods, if not kept at the correct temperature it could lead to serious ill health. This is why it is imperative to close your cold room doors and keep your temperature maintained.

What Other Features Are There to a Door Sentry Alarm?

After successfully launching as a 230v wall-mounted form in 2014, over 2000 units have been retrofitted within two of the UKs leading supermarket groups, as part of their energy-saving initiatives.

As a direct result of the Door Sentry alarm’s success, there are now 24v options available!

The Door Sentry alarm system has a wall and panel mount, can play a range of different audio messages and has a tamperproof case and sensors. It also comes with a kit of installation parts, and the option to customise your input and outputs (EG: connecting the lighting circuit to switch the light off when the cold room door is closed).

Additionally, you can engineer the volume and times of your alarm system to make it bespoke to your business and requirements.

Fan Speed Optimiser

It has also been recommended to use the Door Sentry alarm in conjunction with the Fan Speed Optimiser. This is because the Fan Speed Optimiser has been specifically designed to reduce the amount of direct (and indirect) energy used by evaporator fan motors within chiller cold rooms and walk-in freezers.

The Fan Speed Optimiser has an average energy saving of 36%, and works by using the signal produced from the Door Sentry alarm to reduce the fan speed.

This not only makes it a more comfortable temperature when employees enter your cold room, but it can help to save more energy and reduce the amount of warm air entering your cold room.

The Door Sentry Alarm system is a beneficial energy-saving cold room door accompaniment that could lead to lasting savings when running your walk-in chillers and freezers – making it the perfect solution for all industries and requirements!
