All products must meet our strict environmental criteria, alongside the wider issues of practical kitchen operation, food safety and hygiene. This includes:
- Minimal environmental impact
- Operating and whole life cost benefits
- Long service life
- Regulatory conformity/third party verification
- Refrigerant selection
- Value for money
- Food safety and hygiene
- Performance – build quality, reliability, safety
Selecting the right components is key to delivering our Greenlogic objectives.
Williams’ commitment to green refrigeration stretches back decades. In the 1980s we were the first manufacturer to develop CFC-free insulation.
We’ve pioneered a raft of greener technologies, ranging from energy-saving Smart Controllers to systems using eco-friendly refrigerants such as hydrocarbon.
Our products are 99% recyclable with the remaining 1% consists of condensate from compressors, which is treated by a third-party partner. Even our used oils go through a purification process that sees them refined and filtered, with the oil residues burnt in furnaces to make energy. Foam is shredded and bailed, which is also used to produce energy.
To ensure our products are amongst the most sustainable in today’s market means considering each and every component. Not just the contribution they make to the product’s overall energy efficiency but the impact they have on the environment, and ensuring they have been produced in a sustainable and ethical manner.
Our CoolSmart Controllers minimise the cabinet’s energy consumption through processes such as fan and heater pulsing, intelligent defrost and independent management of evaporator and condenser fans.
Our insulation delivers structural strength and superior thermal properties while minimising environmental impact, through low GWP (Global Warming Potential) and zero ODP (Ozone Depletion Potential).
Our low energy fans resist corrosion to maximise service life. Our coils are electro deposition dipped – an advanced high quality cathodic coating technology. This has a lower environmental impact due to a reduction in the amount of solvents used.
Our products also include a comprehensive choice of additional energy saving features and options such as self-closing doors, heavy duty gaskets, half doors and drawer packs.
Williams follow the AFE Group Ethical Trading Code and ensure compliance with it by our suppliers as well as every supplier being assessed and graded on the environmental management of their product and plant.
Williams first developed the use of natural hydrocarbon refrigerant back in 2007 and began exclusively introducing greener refrigerants for much of its ranges, including reach-in models and modular products, in 2013. Now, we use natural refrigerants as standard for all our range of food storage cabinets.
Hydrocarbon refrigerant reduces energy consumption due to its excellent thermodynamic properties. It also almost eliminates the environmental impact due to its low GWP and zero ODP. Our low energy compressors, specifically designed for use in hydrocarbon units are all VDE approved as they fall below the 150g threshold for hydrocarbon equipment - significantly meaning that our products can be installed in any location irrespective of room size.
