    A dispenser like no other…

    SafeLink MPD is DEMA’s newest innovation in housekeeping dispensing. MPD is the multi-product and multi-dilution dispenser designed for use with SafeLink closed loop bottle inserts. MPD engages and dispenses one product at a time and is designed for simple, fast and safe changeover from one product to the next. Chemical connects and disconnects to the SafeLink dock with one simple fast step. Simply push the bottle in and it automatically engages. When you’re done filling your bottle or bucket, the chemical is easy to remove and SafeLink closed loop inserts keep concentrate chemical away from you.

    SafeLink MPD is designed with a dilution dial for in dispenser chemical metering or a non-dial system for in bottle chemical metering. MPD dial is designed to use practically every product you could ever need. The dilution dial has up to 9 positions with 2 dilutions at every position for up to 18 different dilutions. Standard dial offerings are a 3 position, 6 position and 9 position to handle any chemical offering. And of course MPD has all the user features you have come to expect from a DEMA dispenser. Two proportioners and fill ports provide easy bottle filling and convenient bucket filling. The bottle filling has 1 handed activation and the bucket has an optional remote “gas pump” activation. The bottle fill tube is designed to minimize foam and the drip tray in incredibly functional with an optional drain hole and tube.

    MPD is versatile, easily accepting bottles anywhere between ½ gallon to 5 liters in size; it’s perfect for any chemical program. Customization is a breeze; MPD is available with multiple color options to match any brand strategy. Stop by the booth and see the most innovative dispenser in the market today.

    Choosing the right Housekeeping solution for your customer’s requirement

    Your housekeeping dispensing offering should be made based on a few key factors. The most critical components in making the right decision are the customer’s needs, equipment cost and your chemical packaging. If you keep these top of mind, answer and ask a few questions, you will make the right decision for your business and your customer.

    Customer’s needs should be evaluated from the owner or supervisors as well as the worker’s point of view. Management may have security concerns that require locking dispensers, or their focus may be about training and want the easiest to use solution for their employees. Whatever their needs and concerns, make sure you ask what’s most important. The simplest questions to answer are:

    • “What chemicals do you need? “
    • “What are your primary applications?”
    • “How many products are used in spray bottles or hand buckets?”
    • “What products are needed for bucket and/or equipment filling?”
    • “Do you need the ability to spray-on products?”
    • “Do you move the same product around and fill at different locations (portability)?”

    Single product and 2-5 product systems that use dedicated fill ports offer the most simplicity for the worker. Dedicated bottle or bucket fill tubes and dedicated activation points require few decisions to make the right chemical choice. Selector valve systems provide up to 4 products for each bottle or bucket fill port by using a dial to select between the products. Selector valve systems do add some complexity however if you label the unit well and train the employees thoroughly, it can be the preferred system of the end user.

    Locking dispensers can increase safety and security. Knowing how many products and the dimensions of your chemical containers will make sure you make the best decision. DEMA offers multiple modular locking enclosures for ½ gal (2L) and 1 gal (5L) containers that can be set-up as 1-5 or more product locking systems. We also offer single enclosures for 4 products (both ½ gal and 1 gal) and single enclosures for 1 product gal containers.

    Balancing the cost of dispensers to chemical usage is always a critical factor. Two cases of chemical per chemical location will typically more than cover the cost of the dispenser. In general, single or dedicated systems without locking enclosures and basic wire racks (or no racks) are the most cost effective for 1-2 products. Selector valve dial systems are more cost effective for 3+ products. Basic wire racks are the most economical solution for mounting chemical on the wall. And plastic locking enclosures are a lower cost than stainless.

    New Out of Product Sensors

    DEMA’s most recent “out of product” sensor uses a unique conductivity sensing design. The sensor recognizes the presence of liquid media using conductivity but without direct exposed metal tips or probes. Instead the design uses conductive plastic which has been engineered into the body of the sensor. This design offers good chemical compatibility, thus eliminating issues with traditional metal tip conductivity sensing.

    As with previous DEMA sensors these sensors can be installed directly on the inlet side of the pump using “push on” fittings or barb connections. The sensors can be electrically connected to a Titan or Nitro ware wash system without any further programming or setup required. Additionally, DEMA offers a Low Level Module that will accommodate the new sensors as well. The Low Level Module can be coupled with an Atlas or V-Line laundry system or be a standalone module for laundry, dairy, and other industrial applications.

    Sensor and Low Level Module Kits

    • DEMA P/N – 84.65.64 – 3/8” Barb fitting at each end
    • DEMA P/N – 84.65.65 – 3/8” Push-on fitting ready at each end, includes 2pcs of a 3/8” x 3/8” Push-on coupling fittings – Ready for Atlas and V-Line applications (laundry).
    • DEMA P/N – 84.65.66 – 3/8” Push-on fitting ready at each end, includes 2pcs of a 3/8” x 1/4” Push-on coupling fittings – Ready for Titan and Nitro applications (ware wash)
    • DEMA P/N – 84.65.67 – 3/8” Push-on fitting ready at each end.
    • DEMA P/N – 84.65.48 – Low Level Alarm Module (standalone)

    Tech Corner: Differences between Injectors and Proportioners

    It’s not uncommon to find people using the terms “Injectors” and “Proportioners” interchangeably, however, that’s not correct. To clear up some of the common confusion, we’ve broken down the difference between the two below.

    Injectors and proportioners are similar in the fact that they both use the venturi effect to create vacuum. The venturi effect is: “Water flowing through a nozzle with the stream of water going across a port that will draw in air or chemical into the water stream.” The difference, however, is that injectors are installed in line with the water source and proportioners are installed at the end of the water source.

    Injectors are tricky to size because of back pressure. To properly size an injector you have to have the pressure of your water line the injector is going to be in and the flow rate at the end of the line your injector is in. An injector has to have a small amount of back pressure to prime. If you have too much restriction at the end of your line, the injector will not draw because the back pressure is too great. This occurs mostly when there is some kind of nozzle attached to the discharge. Also if there is no back pressure at all the injector cannot prime.

    Just remember when sizing an injector get the water source pressure and the flow rate of the discharge. If there are multiple nozzles on the output, measure the flow rate of each nozzle and add that up to get your total flow rate in GPM (gallons per minute). Never size an injector by the size of the pipe you are installing it into.

    As mentioned previously, Proportioners use the venturi effect as well. With the proportioner located at the end of the water source, this is typically used to fill quart bottles or buckets. At DEMA, we use a 1 GPM proportioner to fill bottles and 4 GPM proportioner to fill bucket. The proportioner controls the flow rate of the water source. As the proportioner is at the end of the water source, back pressure does not have an effect on the proportioner.

    Have questions about injectors, proportioners, or anything else related to chemical dispensing? Contact your Regional Sales Manager or call our Technical Service department at 1-800-325-3362.

    Tech Corner

    Lets go into a commercial kitchen to discuss proper location for unit installations. The most critical step in any installation is location, location, location. Location will be based on what type of unit you are installing such as electronic warewash, sink or drain dispensers.

    Electronic warewash dispensers require electricity regardless if it comes from the dish machine or a wall outlet. Find a location that you have access to electricity, a flat surface, and make sure it is it is far enough from the machine where it will not be exposed to steam.

    Sink dispensers require water to operate. Locate a flat surface with the access to water, and the ability to use the unit without causing disruption to the workflow in the kitchen. Another very important consideration is the location of the chemical to the dispenser. The chemical must be below the dispenser. If the chemical is located above the dispenser, it will create a siphon and the chemical will continue the flow out of the unit even if the unit is off.

    Hand pumps are similar to the sink dispenser in the respect that the chemical must be below pump. It will also create a siphon and continue to discharge chemical when the unit is not in use. Also worth remembering, a hand pump will stick out from the, so mount accordingly as not to get in the way of hanging pots, pans and other equipment.

    Drain dispensers require a tube to go down into the drain. Find a flat surface close to the drain that is not in a high foot traffic area. You don’t want someone to trip on the discharge hose and get hurt or damage the unit itself.

    Another consideration is whether you want to use a battery operated unit or an electric unit. That can make an impact on which type of unit you purchase and the location of the installation. If you have any questions about surveying for installations, contact DEMA Technical Services or your Regional Manager.
