According to its website HJ Weir Engineering Co Ltd is “one of the world’s largest manufacturers of flatwork finishing equipment.” It adds that it is known as the ‘originators of flatwork handling technology’ and that it has been “providing separating, feeding, ironing, folding and stacking solutions globally for over 55 years… our many years of experience coupled with innovative design and one of the most advanced yet simple control system makes us an unrivalled leader for the industrial and commercial laundry sector.”
HJ Weir is the UK and Ireland dealer for Milnor’s product range. According to Ross Weir, managing director, Milnor has been producing washers for over 70 years “and has earned the reputation of supplying some of the most robust and efficient products on the market today.”
In terms of large washer-extractors HJ Weir is promoting “the very popular MWF range” that can be supplied in sizes from 27kg – 125kg. All MWF models come with the latest MilTouch Control which utilises resistive touchscreen technology and full VGA resolution; Weir says that the screen has a clear and informative display which shows current machine status information including total formula time and time elapsed; “and with complete programming flexibility, formulas can be developed on a computer, saved to USB external memory, and uploaded with a touch of the screen… with intuitive fault diagnosis and relevant troubleshooting suggestions, the MilTouch control streamlines employee training and eliminates operator guesswork.”
A new feature for 2020 is a weighing option – a weigh cell with electronic flow meter. This option, says Weir, “ensures that the machine processes goods efficiently with every single wash.” He says the weigh cell works by capturing the weight of the goods loaded in the machine. Once loaded, the algorithm in the controller calculates the correct proportion of water to goods based on weight. The electronic flowmeter then ensures that the right amount of water is delivered to the machine based on the weight of the load. Likewise, Weir says that wash chemistry is adjusted to correspond to the weight of the load in the machine – “this means loads that are smaller than the machine’s maximum capacity are washed in the correct amount of water and wash chemistry.”
A standard feature on the Milnor range is what the company calls RinSave which allows for the basket to reach a precise G-force that ‘slings’ the wash liquor (including water, chemistry, and soil) out of the load after a wash step. “This,” asserts Weir, “will save up to two rinses per load and fill/rinse time.” Another development that Milnor totes is bigger cylinder perforations that, Weir says, “provide better wash quality by promoting excellent interchange of the goods with water and chemistry, better rinsing by allowing rinse water to freely interact with the goods, and better extraction by allowing water to escape from goods easily and quickly.” He adds that a tall rib construction and precise cylinder speeds combine to “provide excellent MAF – Mechanical Action Factor.” On top of this, Weir says that spacious wash cylinders provide more room for lift and drop action and for goods to open and absorb wash and rinse water “ensuring goods get clean the first time, reducing time-consuming and costly rewashes.”
Milnor also has built in what it says is a “dynamically tuned suspension feature” which Weir describes as “a cutting-edge design that employs a unique, two-point suspension system.” In describing it, he says that its centre of mass is located where an imbalance would occur. A smooth coil suspension system, constructed of engineered fabric and rubber layered coils, provide low natural frequencies and vibration is isolated, “delivering smooth operation and performance.” According to Weir, “dynamic forces are evenly applied for minimum vibration, which provides smooth extraction, less wear and tear, and longer machine life.” Allied to this, tapered roller bearings have a large contact area which spread forces; the front and rear bearings are fixed in the same housing, preventing damaging misalignment, and a pressed-on basket means it does not need to be replaced when a bearing change becomes necessary.
Weir concludes by saying that “every Milnor design model is tested for a minimum of 1,000 consecutive hours in a high-extract, out-of-balance state – ensuring your machine is tough and will stand up to years of use.”
As an aside, for backup to its customers, HJ Weir says that it carries an inventory of over 15,000 spare parts at its manufacturing facility in Chepstow in South Wales. Says Weir: “By using genuine spare parts, we are able to maintain excellent operational capability of equipment after repair or maintenance and help reduce our customer’s maintenance costs.” He adds that 80 per cent of the held spares are available to be supplied on 24-hour express delivery with established couriers.
