Day: 26 February 2021 In our experience, the best architects and contractors have the ability to look at all the design aspects of a new project, taking into account every challenge they may face and uncovering every possibility open to them. Nevertheless, when the new build or refurbishment includes an on-premise laundry, even the most seasoned building experts need and benefit from our specialist advice…which this commercial laundry planning guide aims to provide. Location Ideally, the laundry should be situated on the ground floor of a build, to facilitate easy laundry equipment access and to alleviate structure-borne vibration which could cause damage. The chosen site should consist of at least one external wall to receive dryer exhaust ducts and air inlet panels without the need for expensive and troublesome fan assisted systems. Natural light is always preferred to provide laundry staff with pleasant working conditions. However part of the external wall should be window free so tall dryers or stack towers do not obscure natural light. For infection control, always plan the laundry away from the kitchen, ensuring that food and soiled linen do not share the same corridor.). Flooring Where possible the laundry floor should be a solid concrete ground floor slab – even if the rest of the ground floor is suspended PCC beams. Timber floors should be avoided, and underfloor heating must be omitted from the area where heavy duty washing machines will be installed. An insulation layer between the structural floor and the screed must be omitted from the area to receive the washing machines – under-screed DPMs should be avoided. Where PCC floors or block and beam floors are unavoidable, your appointed structural engineer must be consulted. In most cases a concrete plinth will need to be cast on top of the structural floor (not the screed) to receive holding down bolts. Layout The laundry room should have a ‘soiled/in’ door and a ‘clean/out’ door. Regardless of dimensions, the room should be designed with 1/3 of the space available for the ‘wet’ side and 2/3 for the ‘dry’ side – each with sorting and storage area. A fire exit on the external wall should be included, which could also satisfy the machine access requirement, should machines may need to be swapped or upgraded after the completion of the build. Machines Commercial or industrial grade equipment is a must in on-premise laundries – both for practical and regulatory reasons. Using our vast experience and insights built up over decades of listening to our care customers, we have developed a full and varied range of WRAS-approved, washing machines, energy efficient tumble dryers with a unique S.A.F.E (Sensor Activated Fire Extinguishing) system, ironers, finishing equipment and detergents – as well as our ground-breaking OTEX ozone disinfection system which enables commercial settings to be HTM01-04 or HACCP compliant from the outset and minimise a site’s carbon footprint in the long-term. Our ever-growing portfolio means always have the right equipment solution for any client need – and our planning team have the direct resource required to feed equipment into all types of project following the scoping and design stages of a build. Utilities A foul drainage SVP or stub stack (min. 100mm diameter) should be situated in the ‘wet’ side of the laundry. The portion of external wall to receive the dryer ducts and air inlet panels should be in the ‘dry’ side. As a rule of thumb each washer and ironer will be three phase, generally around 32 amps per phase. Dryers tend to be single phase 13 amp if gas heated or three phase if electric heated. Hot and cold water supplies which supply up to 24 litres per minute at 1.5 bar minimum are required under normal circumstances. JLA washers are fitted with a built in type `A` air gap, which means dedicated water services and back flow prevention devices are no longer required. Exhaust outlets and inlets For dryers… A tumble dryer operates as a forced draught unit. That is to say that the fan inside the dryer actually draws air out of the room and into the dryer. The air is then passed over the heat source (gas, electric or steam coil) and into the drum to dry the linen, therefore being forced outside via the exhaust duct. This is why the exhaust duct and the air inlet panel into the room are always the same size irrespective of the type of heating the dryer uses. The duct size and air inlet panel size increases in proportion to the size and number of the dryers in the laundry. JLA can provide exact details and sizes of these once the specific dryer types and quantities have been agreed. The dryer outlet to atmosphere (even for gas dryers) is completely harmless, albeit unpleasant and musty in odour. The duct can be vented out at any point, high or low, where the odour is least likely to cause offence (away from open windows and the air inlet panel). It is often believed that the exhaust from a gas dryer is harmful due to the presence of combustion gases. Whilst this is technically correct, because the dryer is a forced draught unit the air passed over the heat source has diluted the combustion gasses to the point where they account for less than 2% of the total volume of the exhausted air and are therefore harmless. For boilers… The discharge or flue from a boiler is different to an exhaust duct from a dryer in that its content is made up entirely of combustion by-products such as carbon dioxide. The flue must always be terminated at high level out of harm’s way and must always travel in a vertical direction – 45 degree bends may be employed to adjust its route, but never 90 degree bends.

When visiting food processing sites to talk about the many laundry solutions we offer here at JLA, almost without exception the person we meet is keen to hear all about the alternatives to outsourcing laundry – and the majority are open to installing an on-premise laundry (OPL) in order to cut costs. However, even though the potential for savings is huge, many mistakenly assume that the move to OPL will be risky and fraught with hassle. At face value, it’s perfectly natural to err on the side of caution and air concerns about transitioning from one way of working to another – after all, every penny counts and every minute matters in the food industry. Indeed, one or two of the common misconceptions listed here may be niggling away at you as you weigh up the possibility of laundering on-site. But by addressing your likely concerns, we hope to reassure you that on-premise laundering is, without doubt, in your best interests. “Doing everything myself? Sounds expensive…and difficult!” It really isn’t…especially when the alternative is to continue using a commercial laundry whose prices will continue to rise and rise over the next decade. By outsourcing you are paying thousands of pounds more than you need to each year by committing to substantial clothing stocks, hidden supplementary charges and unexpected price rises. All that disappears when you take control of your own laundry, and you’ll benefit from reduced clothing stocks, transparent pricing and lower processing costs, while escaping harsh penalties or surprise charges. “What about the hassle of HACCP?” We have our own technicians and chemists who can advise you on the best practices, and we work closely with experts from the industry who can help you form a plan of action and assist in the actual development of fit-for-purpose HACCP documentation. With JLA OTEX Ozone Disinfection technology you have access to immediate verification to prove that your wash has been disinfected, with either a printed receipt, helping you to complete your HACCP/ISO documentation quickly and easily. “I don’t know what equipment I need” Not a problem. We can specify any laundry of any size in any setting. In the main, there are two types to consider, and we have the washers, dryers, barrier systems and disinfection innovations to help you get the best out of one or both. The ancillary laundry An ancillary laundry will allow you to process all the items your linen provider won’t touch – items that can potentially be damaged by traditional thermal disinfection. These include specialist clothing materials, microfibre cloths and mop heads, slash guards and your drivers’ & engineers’ clothing. The full on-premise laundry This will give you a full laundry facility for 5 to 5,000 employees in both low risk and hi-care production units. A full laundry facility will disinfect as well as clean, and will ensure you meet strict compliance regulations in the process. “But what if it breaks down?” Simple, just call our emergency call-out line and one of our engineers will be with you inside 8-working hours as part of your Total Care agreement – 7 days a week. If you opt to purchase machines outright, we can provide equally quick response with a standalone service package. “I don’t have the staff to operate a laundry.” You do if you redeploy the employees who are currently counting in and out, collecting laundry from locker rooms, waiting for deliveries and storing all the spare sets of workwear you need. Plus, if you manage your laundry by trusting someone else to do it…can you be sure that they’ll meet your expectations? Once laundry leaves your site, it’s open to a number of risks – and the third party could fail to reach guidelines that must be adhered to in order to comply with BRC best practice. 9 out of 10 customers we’ve helped to install an OPL have needed no extra staff to run it. “I don’t have the space.” Strangely enough, when we explain to companies just how much we could save them, space is no longer an issue. You’ll be surprised by the amount of space needed, and in reducing the clothes stock ‘PAR’ needed you can simply use areas of your business that would otherwise be used for storing spare workwear. Our approach is to simply get the best out of the square footage you have, rather than reinventing the wheel. JLA planners and designers will gladly discuss all the options open to you, and will never over-sell or under-spec. If you need a small machine to take care of occasional ancillary laundry, that’s all we’ll recommend. Equally if you need a full high-hygiene facility, we have the expertise, machines and experience to make sure you have everything you need.
