Undercounter glasswashers & dishwashers

What is the difference between a Standard and a DUO warewasher?

Standard Undercounter glass and dishwashers are incredibly easy to use, simple to clean and deliver excellent wash results. They come as standard with built in chemical pumps, double skinned door, gravity drain (optional drain pump), simple two button controls, easily removable basket guides, wash arms, filters and an energy saving standby mode.

Duo Undercounter glass and dishwashers have all these standard features plus an LCD display, Water Board (WRAS) compliant air gap, double skinned cabinet and door, built-in rinse booster pump and drain pump, stainless steel filters & optional integral water softeners.

Do I need a drain pump or gravity drain?

Unless ordered with a drain pump, the entry level (Standard) machines will come with a gravity drain meaning that the waste from the machine outlet is being carried out purely via gravity. This is fine when the machine is elevated (e.g. on a stand), or if the drainage point is below the machine’s waste outlet.

A drain pump is required when the waste water has to travel higher than the machines waste outlet.

Do I need a Water Softener?

The majority of the UK is a hard water area which can lead to a build-up of limescale in the machine and its heating elements. This can shorten the machine’s life, affect its performance and cleaning results. A water softener prevents this by reducing the hardness of the water before entering the machine.

Chemicals - Do I need automatic dosing?

Our range of products all feature integral detergent dosing systems. These are carefully calibrated to match our chemical specification and your wash conditions. By calibrating the output of detergent and rinse aid, we are able to give you the best and most cost-efficient results.

What is WRAS and why is it important?

WRAS Approval is the accepted way to demonstrate compliance with the Water Supply (Water Fittings) Regulations & Scottish Byelaws.

Duo machines are fully compliant and feature a ‘Type A’ air gap, meaning that there is a physical air gap which completely prevents the water from entering and contaminating the mains water supply. Standard machines have a lesser ‘Type B’ certification which means the machine contains backflow prevention devices complying with EN 61770.

What electrical connection will I need? (13A single phase, 30A single phase or 13A 3phase)

The majority of our machines have optional electrical connections. To get the best heating and recovery performance from our machines we always recommend the highest connection where possible (13A 3phase, or 30A single phase).

We do offer a 3-pin (13A single phase) connection on all our undercounter machines for convenience; however please note for 500mm basket machines the overall rack performance and heating times of the machines on this lower supply will be considerably reduced – if it must go on this connection we recommend a hot fill to minimise the amount of heating performance required (water supply must be below 60°C).

Which machine will I need to handle our footfall?

There are various factors to consider when choosing a glass or dishwasher, but most importantly, determining what needs to be washed at peak times, on the busiest day of the week, is crucial to sizing the correct machine. Once this is understood, this can be converted into the required dishwasher racks per hour. Get this right, and the heart of the warewash system will make the overall design flow and work.

If you are unsure of what model to choose, please contact us and we can help you choose the right machine for your requirements.

Pass through dishwashers

Pass through dishwashers are suitable for when there is a high volume of covers and items being returned to the wash up area. These normally have a 1.5 or 3 minute wash cycle (40/20 racks per hour). Working in conjunction with inlet and outlet tabling, these machines can be designed to work inline or as a corner operation.

It is highly important to consider the entire wash system – what items (plates, crockery, cutlery, pans) and the way they are returned to the wash up area (pre-sorted or not) when deciding on a pass through dishwasher, to make sure that you have an area that is operating to maximum efficiency and not bottle-necking during busy periods.

Rack machines

Rack machines have a capacity of anything from 100 to 300 racks per hour. These machines are designed for volume catering which means the return and set down area is extra critical, as is the space for pre-sorting prior to washing. Any design defects at this stage will cause chaos.

In the staff canteen sector (business and industry), many rack type machines are fed by conveyors. It’s the conveyors which determine “the pace” of the entire wash system within the dishwash area.
