    1. Are You Concentrating Yet?

    Welcome to our latest blog series covering the subject of chemicals and dosing. A hot topic in

    the trade press, the six-part series will discuss the most important issues surrounding the

    chemical dosing landscape.

    Chemical Dosing: A Brief Overview

    Chemical dosing systems, whether manual dispensing pumps or electronic dosing units, have

    been around for 30 years or so. The core premise of both is the same – the use of equipment

    to enable the end user to accurately dose or dilute a chemical concentrate at the point of use,

    to give a ready to use cleaning or disinfecting solution.

    Active ingredients make up a very small percentage of the composition of ready-to-use

    cleaning products – the rest being water. In the past, this meant that large multi-site

    organisations were spending a significant proportion of their cleaning expenditure on ‘buying

    water’. With water being a readily available and cheap commodity in most developed

    countries, the solution lay in pushing up the concentration of active ingredients. This is what

    RP Adam has done over the last decade or more by manufacturing and marketing

    concentrated chemicals.

    Over the last 15 years, great strides have been made by the major dosing equipment

    manufacturers. Dosing systems are now simpler to use, easier to install by technicians and

    more reliable in terms of lifespan and accuracy of dilution control.

    It used to be that only the larger global corporations could afford to supply free-on-loan

    equipment and resource with adequate engineering services. This is no longer the case.

    Today, the provision of dosing equipment and associated engineering services is much more

    accessible and more affordable to a wider spectrum of businesses.

    Customer Expectations

    The above has been a positive and progressive trend for both supplier and customer, and has

    put economy in use higher up the agenda.

    Many customers now expect chemical dosing stations as part of their cleaning package.

    Suppliers can sometimes find managing these expectations a difficult task, especially if the

    user’s financial contribution (spend) is not in line with the investment required by the supplier

    to supply, install and service the equipment on an ongoing basis. We will look at this subject

    in greater detail in future posts within this series.

    Topics Covered

    Key topics to be examined will include:

    1. The types of cleaning & disinfection concentrate available and how they need to be

    designed properly to make controlled dilution work to maximum effect i.e. in terms of

    lowest in use costs and effectiveness of the cleaning and disinfection solutions.

    2. The types of manual dosing equipment available including chemical to water types

    and water/chemical mixing stations; the things to consider when choosing the right

    type of system.

    3. Electronic dosing equipment for dish and glass washing, liquid laundry and drain

    dosing applications.

    4. The importance of effective engineering capability to a) respond to machine

    breakdowns, b) maintain/replace equipment parts within a wider preventative

    maintenance programme, and c) have the capability to roll out national multi-site

    contracts efficiently and on time.

    5. How suppliers assess the commercial viability of providing free-on-loan dosing

    equipment and avoid some of the pitfalls when costing out contract investment.

    Doing It Right

    We believe, to do it properly, supplier businesses should expect to invest up to a double digit

    percentage of their turnover in the provision of free-on-loan equipment and professional

    engineering services each year.

    Clearly, this will vary between business types and the sectors they are active in, but there are

    no short cuts – you either commit and resource properly or you don’t. It is critical, therefore,

    that there is a solid business model supporting investment in their clients’ operations.

    All parties (supplier, distributor and end user customer) need to be clear on who is investing

    in what and who benefits from such investment. The supplier and the distributor hopefully

    receive a longer-term supply commitment, with the customer gaining the in-use cost and

    lower wastage benefits of dilution control.

    Chemical Dosing at RP Adam

    RP Adam invests heavily in time and money to help research and develop new dosing

    equipment technology, collaborating with leading equipment manufacturers to assist them in

    bringing new innovations to market. We are frequently asked to participate in Q&A sessions

    when the concepts are at design stage and take part in soft launches to ensure these systems

    are fit for purpose in a real and demanding working environment.

    It is in our interest to ensure that these system innovations can handle the rigours of the

    modern cleaning world. Likewise, equipment manufacturers have a high regard for our

    concentrated products and use them for upper limit chemical compatibility tests to check that

    the dispenser components can handle high chemical concentrations and will not corrode over

    Stephen Woolmer, CEO of UK based Brightwell Dispensers Ltd says:

    “As equipment manufacturers we are under pressure to expand our expertise, product and

    service offering in line with emerging customer needs. For decades, RP Adam has collaborated

    with Brightwell Dispensers to develop some of the most innovative, reliable and accurate

    dosing systems on the market today. Our focus has been to deliver cleaning professionals a

    safe, precise and economic chemical management system for a multitude of applications such

    as catering, laundry and housekeeping. With a combined experience of nearly 200 years, our

    family business shares a vision to offer our customers first class service, support and innovative

    2. The Key Benefits of Using Concentrates

    In part two of our six-part series we examine the stand-out benefits of using a controlled

    chemical dispensing system and chemical concentrates and wonder why more businesses are

    not realising these.

    The cleaning industry has a reputation for being quite innovative, but it is the translation of

    these benefits into the B2B commercial sphere where we find some resistance from the end

    user; despite compelling evidence that using concentrates and chemical dosing systems can

    immediately deliver real businesses benefit in many areas.

    There are four key reasons to embrace concentrates and chemical dosing:

    1. To reduce the amount of packaging waste and to control chemical consumption

    thereby improving a business’s environmental profile and reduce its carbon footprint.

    2. To ensure the accuracy of disinfectant solutions so that critical food-contact

    equipment and surfaces are disinfected to meet industry standards. Similarly, for

    health care and washroom surfaces where there is a potential for cross contamination.

    3. To be able to control cleaning costs in a disciplined way rather than rely on end user

    free-hand pouring or continued use of expensive and environmentally unsound

    readyto-use pre-packed cleaning products.

    4. To reduce the risk to users of accidental contact with potentially hazardous chemical

    products and thereby improve the safety profile of your business. http
