Airedale are proud to have products that comply with the Energy Technology List (ETL) criteria, a Government scheme that sets the performance criteria of highly energy efficient products.

98% of Energy Technology List (ETL) approved products in the ‘Packaged Chillers’ European Seasonal Energy Efficiency Ratio (ESEER) category, are Airedale products. The category features 226 Airedale products from two product ranges, The TurboChill™ and TurboChill™ FreeCool in both R134a and R1234ze refrigerants.

About the ETL

The ETL (or Energy Technology List) is a government managed list of energy efficient plant- and equipment-, such as boilers, electric motors, air conditioning and refrigeration -systems. It is part of the Enhanced Capital Allowance (ECA) tax scheme which means that a business can invest in energy-saving plant or machinery that might otherwise be too expensive.

The first year allowances let businesses set 100% of the cost of the assets against taxable profits in a single tax year. This means the company can write off the cost of the new plant or machinery against the organisation’s taxable profits in the financial year the purchase was made.

An ECA is claimed through a company’s income or corporation tax return in the same way as any other capital allowance. HM Revenue and Customs is responsible for the tax-related aspects of the ECA scheme.’

As a result of substantial overall energy cost increases in recent years, alongside increasingly stringent environmental legislation, there is continuing pressure on organisations to focus on reducing their energy consumption.

Buying energy efficient equipment results in reduced energy costs and a quicker payback period, which is a very attractive proposition. For many organisations, energy use can be the second highest cost, after employee salaries, and for energy intensive industries it can be the highest operational cost.

Unnecessarily high energy use does not just impact financially; it also results in excessive carbon emissions that add to business tax costs such as the CRC Energy Efficiency Scheme or the Climate Change Levy.

Mike Peachey Product Development Manager at Airedale

Airedale has had Chillers on the Energy Technology List in the past when the Energy Efficiency Ratio (EER) was used to differentiate one chiller’s energy efficiency from the next.

The EER was taken at one full load condition which might happen for only a small percentage of the year. The Carbon Trust laid out a threshold EER, and it was a one-shot efficiency point.

More recently, the test metric has moved from an Energy Efficiency Ratio (EER) to a European Seasonal Energy Efficiency Ratio (ESEER).

Mike Peachey, Product Development Manager at Airedale International believes the Carbon Trust is moving in the right direction by adopting the ESEER metric. He believes it will be a better metric to determine which products are truly more efficient over an annual cycle.

    “The new ESEER thresholds are a step in the right direction. With the EER threshold we compared the efficiency of products at an ambient temperature (35°C) which occurred for only a couple of hours per year, if at all, in certain areas of the UK. The current ESEER covers ambients down to 20°C, incorporates part load efficiencies and weightings more realistic of an annual cycle."

    "The true aim of the scheme is to reward end users who are using the most efficient products. When the new Ecodesign targets come into force in January 2018, particularly the metric SEPR (Seasonal Energy Performance Ratio). It is an opportunity to rationalise on which metrics are used. It is important to incorporate the lower ambients and even Free Cooling capabilities of products where applicable. After all in the UK, the most common ambient temperature is around 11°C.”

For Airedale, featuring products on the Energy Technology List acts as a large incentive for the customer, and differentiates an efficient product from an inefficient product.

The key thing about the ETL is that Airedale is the only manufacturer that has two full chiller ranges on the list. (The TurboChill™ and TurboChill™ FreeCool in both R134a and R1234ze refrigerants).

Airedale represents 98% of the products featured on the ETL under the ‘packaged chillers ESEER’ category.
Eligibility Criteria and Process

Packaged chillers must meet the ESEER thresholds defined by the Electrical Contractors' Association (ECA). These vary with product category.

Airedale is required to test two representative chillers from each product range in their laboratory, complying with BS EN 14511:2013 and BS EN 14825:2016.

All the test data supplied to the ECA is witnessed or verified by an independent body.
The empirical data is backed up with Airedale’s theoretical predictions for the two representative chillers and the remaining units from the range. All of the data is then cross checked by the technical team at the ECA before it makes it onto the ETL.
Two great benefits of purchasing products featured on the ETL are;

a) Businesses that purchase products listed on the ETL can claim an enhanced Capital Allowance [ECA] – a first year 100% accelerated capital allowance that delivers all available tax relief in 1 year. This is equivalent of 5.5 times the benefit of standard tax relief in the year of purchase.

b) Assurance in purchasing top performing products – typically the 10-25% most energy efficient products in the market.
