Commercial Dishwashers Coming to the ETL

In the fast-paced world of commercial kitchens, efficiency and sustainability are at the forefront of innovation and investment. As businesses continue to navigate the complexities of environmental responsibility, the Energy Technology List (ETL) emerges as a pivotal guide for organisations aiming to reduce their carbon footprint whilst enhancing operational efficiency. 

In an exciting development, commercial dishwashers are set to make their debut on the ETL, marking a significant stride towards furthering sustainable practices within the catering industry. This addition underscores the importance of integrating energy-efficient appliances into commercial settings, as dishwashers play a critical role in the daily operations of restaurants, cafes, and other catering establishments. In this blog post, we will explore the commercial dishwasher models being lined up to join the list, discuss the criteria and requirements of equipment and some of the brands that might be the first to benefit from a place on the ETL.

What Does the ETL Do? 

The Energy Technology List (ETL) serves as a robust tool in the UK’s environmental strategy to guide businesses towards making greener, more energy-efficient choices in their equipment and machinery. By testing and compiling a catalogue of products that meet strict standards, businesses are offered a reliable resource to make informed decisions on energy-conscious investments.

By showcasing a comprehensive range of products that meet stringent energy performance criteria, the ETL actively encourages the purchase of higher efficiency products, thus driving the market towards innovation and sustainable practices. It stands as an invaluable resource for companies committed to reducing their energy consumption and, subsequently, their carbon emissions. 

In a tangible financial incentive to bolster this green transition, the government’s Annual Investment Allowance (AIA) Scheme plays a critical role. Businesses that invest in products listed on the ETL can claim 100% tax relief on these purchases within the same tax year, providing a significant financial benefit and further incentivising the move towards energy-efficient technologies. 

This synergy between the ETL and the AIA Scheme showcases the government’s commitment to fostering a greener economy, helping businesses to contribute positively to the nation’s environmental targets while also reaping the rewards of reduced energy costs and improved operational efficiency.

 Catering Equipment on the ETL

The ETL previously comprised of energy efficient equipment and machinery including commercial refrigeration. Commercial combination ovens then joined the list in 2013, bringing this efficiency guide to the catering equipment sector. Commercial dishwashers are coming soon! Undercounter dishwashers and hood-type dishwashers will be the first to join and here we delve a little deeper.

Undercounter Dishwashers - Definition, Criteria & Requirements 

Definition:

Stationary rack machines where the front door is pulled down to open the cleaning compartment.

Criteria:

  • Used in lower volume operations
  • Installed under counters
  • Performs multiple short duration cycles approx. 1.5 - 3 minutes
  • Equipment has similar HxWxD dimensions
  • Completes a wash and rinse sequence in every cycle
  • Single tank machine
  • May also feature integrated water treatments to prevent limescale build-up within the machine in hard water areas
  • Glass washers are not eligible

Requirements:

Equipment must perform within these thresholds:

  • Energy consumption/cycle - 0.4 kWh
  • Water consumption/cycle - 3.4 L
  • Power ready to use mode - 0.4 kW
  • Cleaning performance - 90%
  • Must pass hygiene and sanitation standards

Hood Type Dishwashers - Definition, Criteria & Requirements 

Definition:

Stationary rack machines designed to hold standard professional dish racks. As the name 'hood-type' suggests, the compartment has a hood which is raised in a vertical motion to access and insert racks into the cleaning compartment. The hood is then pulled down to close the wash and rinse chamber.

Criteria: 

  • Used in small, medium and high volume operations
  • Performs multiple short duration cycles approx. 1 - 2 minutes
  • Tabling is placed at entry and exit of the machine so that racks can be passed through the wash chamber - hence also being known as pass through dishwashers
  • May have internal or external booster heaters to raise incoming water temperature to the required temperature for the final rinse
  • Single tank machine
  • May also feature integrated water treatments to prevent limescale build-up within the machine in hard water areas
  • May have heat recovery system which recovers heat from the previous cycle to preheat incoming water for the next cleaning cycle.

Requirements:

Equipment must perform within these thresholds:

  • Energy consumption/cycle - 0.6 kWh
  • Water consumption/cycle - 3 L
  • Power ready to use mode - 0.5 kW
  • Cleaning performance - 90%
  • Must pass hygiene and sanitation standards  

ETL reviews testing and accepted standards periodically to make sure only the most efficient equipment appears on the list.

What Brands Might We See On The ETL? 

There are a number of commercial dishwasher brands offering energy efficient features. Here we highlight just a few but could any of these be soon to appear on the ETL subject to strict testing?

Fagor

Fagor undercounter models such as the COP-504 B DD CI Concept+ boast reduced tank capacity for low water usage, and with an Effi-Rinse feature in the Advance and Concept+ ranges, optimal rinsing and disinfecting temperatures are guaranteed. Advance range models have an energy saving mode for added efficiency. The double skinned construction helps to maximise heat retention and promotes quieter operation.
