ERP 2015 drives Air Curtain efficiency

Posted on March 13, 2018

As of January 2015 all air curtains and over door heaters must comply with the requirements of Erp 2015 in order to be sold in the European Union. This applies to products manufactured in the EU and products imported into any member state.
Erp 2015 sets an efficiency rating for all electric fans rated between 125 Watts and 500kWatts. It is more onerous than the requirements of the current Erp 2013 requirements and is part of the European Union’s drive to reduce its carbon footprint as agreed at the Kyoto protocol.
Thermoscreens have been able to achieve compliance with the requirements of Erp 2015 using AC fan decks. This is important for customers since it means that there is no increase in the cost of the air curtain. The alternative method of achieving Erp 2015 compliance is to fit EC fans. EC fans use DC motors which are controlled with an inverter. They are very efficient but cost twice as much as a conventional AC fan unit
Under the terms of the Erp directive manufacturers are allowed to use existing stocks of components and hence Thermoscreens will introduce Erp 2015 complaint fans and fan decks as a running change during the first quarter of 2015. The Erp 2015 compliant components will be identified as required by the terms of the legislation.
Spare fans and fan deck will also change to meet the requirements of the new standard and will be compatible with the current range of products

How Air Curtains Can Benefit Drive-Through Businesses

Posted on March 13, 2018

Air curtains have been used for many years in doorways to shops and restaurants, to provide a welcoming entrance to visitors. However, there has been some debate among contractors about whether air curtains need to be fitted above drive-through service windows. According to an article on Air Conditioning Heating and Refrigeration (ACHR) News, research shows that the benefits are highly significant, and that contractors and business owners alike should take these into account.
 
In the US, the Occupational Safety and Health Administration (OSHA) has listed all drive-through restaurant windows as a potential health hazard for IAQ (indoor air quality), affecting both the staff and customers inside the building. This is due to carbon monoxide and other vehicle emission pollutants entering the through the window – traces of which were found inside stores in Ohio.
 
Similarly, another health hazard for employees is the cold temperatures that staff operating the window can be exposed to. In the long term, this could cause further incidences of staff sickness, thus costing leaders unnecessary expense. Studies also show that a comfortable working environment can help to reduce high levels of staff turnover in the industry.
 
For these reasons, air curtains can provide the perfect solution. And with drive-through businesses booming in today's rapidly paced world, we could see more buildings incorporating this service.
 
Instalment of air curtain systems takes very little time and causes little disruption to usual business operations. The heating control element allows for greater comfort – for both staff and employees – whilst the stream of air filters emissions and pollutants from outside. Another benefit, researchers found, is that it eliminates fly and insect infiltration, thus improving sanitary conditions on the premises.

Air Curtains Help Make York Art Gallery More Energy Efficient

Posted on March 13, 2018

Towards the end of 2012, the York Art Gallery was closed in order for it to benefit from a multimillion-pound refurbishment. In addition to opening up a previously unused roof space, expanding into adjacent rooms and creating a new exhibition space to enlarge the size of the gallery by 60 per cent, the £8 million refurbishment works were also used as an opportunity to improve the building's energy efficiency. 

The use of thermography helped identify the largest areas of heat loss, and where the greatest areas of improvement could be made. The thermal image picked out several points where heat was escaping; the lintels above the windows and some of the windows themselves in the Art Store, compromised, older insulation in the roof space, and through the poorly-insulated flanges, joints and valves of the pipework on a recently installed boiler. 

The thermal survey also highlighted many other ways that energy efficiency improvements could be made. Simple measures such as replacing draft proofing at window installations was one suggestion, as was the introduction of air curtains to improve the energy efficiency and comfort of the building.

Using warm air curtains at the busy entrance doors to the gallery will help lower energy usage by creating a barrier of air that reduces the amount of heating lost through a frequently used door. 

"We will certainly be making the recommendation that a post-construction thermographic survey is carried out to demonstrate any improvements made," said Pete Thompson, Senior Engineer at consultancy firm Arup. 

The York Art Gallery is planned to reopen to the public in Easter 2015.

Top 8 Benefits of Commercial Air Curtains

Posted on March 13, 2018

A correctly installed and fully efficient air curtain can save any business a lot of money by reducing the amount of heat lost through open doors, but Thermoscreens products offer more than just that. Thermoscreens specialise in the design, manufacture and service of commercial air curtains across the UK and abroad. We pride ourselves on the quality of our product and the service we provide, so that our customers have total peace of mind and a reliable and efficient heat retaining system. Here are some of the best advantages a commercial air curtain can have to your business.

Reduces building running costs

An open door is inviting to customers, but it also invites unwanted cold air. Traditional heating systems in commercial units can be very inefficient, especially in large premises with open doors. An air curtain, from a specialist like Thermoscreens, can maximise the savings spent on heating by working in tandem with existing heating systems and reducing heat loss.  

Reduces strain on existing heating systems

With an efficient Thermoscreens air curtain the heat loss through doorways is drastically reduced. When the heat loss is reduced, the existing heating system can have a lot of unnecessary excess strain taken away. This could add up to less usage and increase the lifespan and functionality of your current heating system.  

Reduces CO2 emissions As your building increases in efficiency you will notice the associated benefits of Thermoscreens’ commercial air curtains. Using less energy to heat your building will reduce the amount of CO2 emissions produced; particularly important considering that, from 1st April 2018, all privately rented buildings will need to have an energy rating of E on an Energy Performance Certificate (EPC).  

Reduces Pollution

For units and business on busy roads or in industrial areas with potential air pollution, a commercial air curtain can keep harmful chemicals and smells away from your customers, staff and valuable products. Providing security and protection as well as air heat retention.  

Increases visibility

A closed glass door or doors with obstructions can pose a potential threat to staff and vulnerable customers. Hazards could result in expensive equipment being damaged or even lawsuits. Thermoscreens’ commercial air curtains provide a risk-free alternative with peace of mind that customers will appreciate.

 

‘Open door affect’

Almost any business owner or director will know that open doors tell customers that their business is open for business. An open door is an inviting gesture that has been proven to affect the amount of money customers spend when buying. Using a steady stream of air to form a protective barrier, air curtains block out cold weather, pollution, bad smells and insects leaving you with a warm and pleasant environment inside.  

Increasing customer comfort

Keeping customers happy is imperative to all businesses; cold premises can put customers off and could also affect the productiveness of your staff. Combining an air curtain with a friendly atmosphere and well laid out shop can attract the public within and keep them inside for longer than usual. An air curtain is an investment that will not only reduce your outgoing bills but also increase your incomings.  

Access for the disabled and trolleys

The disabled and customers with buggies or trolleys can find opening and closing doors difficult. Commercial air curtains can provide ease of access for members of the public with their open door capabilities.   With over 50 years in the industry, Thermoscreens is devoted to providing excellent air curtains at competitive prices.

Top tips for Air Curtain installation

Posted on March 13, 2018

Air curtains can help retail, commercial and industrial customers to save energy by reducing the amount of cold air that enters their building, while keeping the warm air inside.  To maximise the savings possible, air curtains need to be designed, sized, installed and controlled correctly.  Here Martin Phillips, marketing manager at Thermoscreens shares his technical tips for efficient air curtain installations.
 
1. Take the time to get it right
A poorly designed, selected or installed air curtain can actually consume more energy than if no air curtain was installed at all.  Take your time to get the spec right and you will ensure optimum performance and happy customers.
 
2. Air curtain vs space heater 
An air curtain isn’t designed to heat a room – it is designed to disrupt natural convection and reduce heat loss around frequently used entrances and doorways.  Although its air stream is warm (unless it’s an ambient/no heat model) and contributes to the heating around an entrance, air curtains actually work alongside a building’s heating system, rather than replace it.  Don’t confuse air curtains with over door heaters. Over door heaters are not designed to form a climate separation but merely to offer some local heating around the door way
 
3. Sizing up
When choosing which air curtain would be right for an application, it’s important to note that they should be specified on the size of the door, not the kW output.  Air curtains are generally available in 1m, 1.5m and 2m lengths and can be seamlessly joined together if needed.  
 
4. Perfectly positioned
Air curtains should be fitted horizontally over a door, or, if necessary, mounted vertically to the side.  They can be surface mounted or recessed, but must be installed inside the doorway, with the discharge airstream as close to the opening as possible.  They should be just wider than the opening with an overlap at both sides (or at the top if it is a vertical installation). 
 
5. Air stream success
It is really important to spend time getting the discharge air stream right; an air curtain won’t be effective if it has too little velocity or is too powerful.  The discharge air stream should be able to discharge air down to floor level  and across the entire width of the opening at a suitable air temperature and speed (2m/s at 30cm above the floor level is a good guide).  Don’t forget to factor in the characteristics of the building (height, orientation etc.) and the outdoor climate conditions (humidity, prevailing winds etc.) as well as the power requirements. 
 
6. Still not sure? Ask for advice
If you aren’t sure about how to set up an air curtain, there’s plenty of advice out there.  An engineering design procedure for calculating the supply air flow and thermal capacity of an air curtain is explained in the BSRIA Application Guide 2/97, Air Curtains – Commercial Applications.  Manufacturers should also be able to provide assistance.

7. Use an efficient heat source 
An air curtain’s warm air can come from various sources, including direct electric heating and low, medium or high temperature hot water.  Modern air curtains are designed to operate with 60/40 condensing boilers and heat pumps to increase their overall efficiency and deliver even greater savings to the customer.  The more efficient the heat source, the more efficient the air curtain.
 
8. In control
Many air curtains use manual controls which allow the user to change the settings for the flow and temperature of the air stream.  In our experience, these controls are very rarely adjusted by a customer so the settings will only be right some of the time, and wrong a lot of the time. To stop this waste of energy and money, automatic controls are now widely availablewhich allow the air curtains to operate at an optimum setting all of the time.
 
9. Whatever the weather
Weather compensation controls can further improve efficiency for a user.  These state of the art controls monitor the outdoor climate via a sensor and automatically adjust the air stream discharge temperature accordingly.  So a warmer temperature will be selected if it is cold outside, and vice versa. 
 
Along with the other members of the HEVAC air curtain industry group, Thermoscreens is committed to helping architects, consultants and installers to select the right products and fit them correctly.

Thermoscreens presents the all-new Compact 2

Posted on March 08, 2018

The latest Compact 2 Air Curtains C2 range takes all that the Compact Air Curtains - C Range has to offer with additional cutting edge technology, new features and style to meet the expectations of both the end user and installer.

With over 40 years as a leading air curtain specialist, Thermoscreens’ latest design comes with a uniquely designed surface mount casing, three choices of controls, lower noise levels, easy to install hanging system and easier access to internal components.

In addition to the uniquely designed casing, the visual profile of the Compact 2 is reduced and allows the air curtain to compliment the surroundings of any frequently used entrance. The Compact 2 doesn’t disrupt the architectural surroundings or the interior design of your space, it provides a discreet solution while providing essential heating support.

We have put a lot of thought and care into the design process to make sure that every angle and aspect has been thought about. Glass doors and windows in shop and restaurant fronts are the best platforms for promoting your business. A cumbersome and awkward air curtain heater can be an ugly distraction to your display, especially where a recessed air curtain option isn’t viable.

All sides have been designed to conceal any fixing details which leave a smooth back plate visible from the street side of the door, especially useful if the structure over the door is glass. The Compact 2 provides an appealing marketing space for a company logo or message to the public.

We continued the great design inside the Compact 2 commercial air curtain with innovative new air blades. The Compact 2 C2 range is equipped with Thermoscreens’ curved fan blades that slice through the air and push it forward with a greater efficiency. It has reduced noise levels by three decibels (dBa) to provide a more peaceful environment in areas such as restaurants and waiting areas where customers may be close to an open entrance.

The Compact 2 reinforces the idea that an air curtain should be discreet and unnoticed. Thermoscreens have moved the air inlet to make it quieter and look cleaner. Now that the air intake has been moved to the top of the unit, it pushes most of the noise upwards and away from customers and staff, reducing sound by a further two dBa.

The air inlet grille can also attract a large amount of pollutants and dust that can build up to make the air curtain look dirty. Our solution have moved the dirt and dust out of sight and so requires less cleaning and maintenance and making the entrance look cleaner.

The Compact 2 is also the installer’s choice of air curtain due to its easy install hanging system. The new design hinged panel provides quicker access to all of the internal components for speedy installation, low service and low maintenance costs.
