Introduction to HL2024 Constant Flow Solutions HL2024 technology and its added value. HL2024 inside - improves water systems and (thermostatic) mixer taps HL2024 Flow Regulators are the heart of any HL2024 product. HL2024 products ensure a constant flow regardless of pressure changes and temperature changes. They are extremely accurate and durable. Built-in into a range of HL2024 products, they serve nearly every situation where constant flow is desired, whether the objective is to save water and energy, to stabilize small or large water systems or to improve the performance of thermostatic mixer taps. HL2024 pressure independent flow regulation flow bar (dyn) This graph shows the constant flow performance of HL2024 products. What makes HL2024 stand out compared to other flow regulators is that it keeps the flow accurately constant at both increasing dynamic pressure and, importantly so, at decreasing dynamic pressure. Both are mandatory for certified pressure independence according to the applicable functional Kiwa requirement for pressure independence BRL-K635/03. Kiwa Netherlands Kiwa Netherlands is the leading authority for the certification of pressure independent flow regulators (and non-pressure independent flow restrictors). Kiwa Netherlands has been running a complete and operational certification scheme for flow regulators for the past 15 years and earned worldwide respect for its technical expertise and for its global auditing and certifying services. HL2024 WORKS - delivers its promise: constant flow A simple idea in a complex product: HL2024 Flow Regulators continuously balance their internal position in order to let the optimal amount of water through at all times. Not too much, not too little. Exactly right. Increasing water pressure reduces the opening, so less water gets through. Decreasing pressure opens the valve again towards its original position. As such, HL2024 permanently reacts to the amount of pressure and to pressure differences in the system. The result is a constant amount of water. This ensures the comfortable use of water while saving water and energy and adds to the stability of water systems. HL2024 WORKS BETTER - better design and materials HL2024 is accurate and reliable thanks to the design and the special materials used. Custom manufactured steel (Sandvik, Sweden), a high-performance synthetic material and a patented design ensure that HL2024 works better than others. HL2024 is the only flow regulator in the market that is certified according to the applicable Kiwa standard for pressure independence. HL2024 KEEPS WORKING - 10 year warranty Unlike common rubber- or silicon-based flow regulators in the market, HL2024 is made of steel and strong synthetic materials to ensure the products strength, flexibility and durability. Rubber and silicon are not as strong, not as accurate and age relatively fast. Its functionality deteriorates faster. HL2024 is designed to keep working for 10 years. Save water - save energy - accurately quantify water and energy savings - optimize water systems - decrease system maintenance - increase system efficiency - accurately and easily determine peak demand - domestic use - professional use - no waste - comfortable and balanced use of water - always the same amount of water - durability 2017 HGP International, the Netherlands www.hl2024.com info@hl2024.com last update: 28 May 2017 En 3 / 22
Important facts about HL2024 About HL2024 technology. Why HL2024 is the world s best working constant flow regulator HL2024 is the first successful marriage between high-performance synthetic material and custom made spring steel in a constant flow product. We found that this unique marriage is the only way to ensure high accuracy and long lasting performance. The specially designed injection moulding process ensures internal product dimensions, exact to thousands of a millimetre. This is vital to the correct functioning of the product. The high-performance synthetic material that holds the spring steel element in HL2024 Flow Regulators is not commonly used in sanitary products or flow regulation products. The material needs to meet more challenging criteria that we found in this particular material: high durability, enough flexibility, high temperature tolerance and high rigidity. Sandvik Sweden custom manufactures the special spring steel with a tolerance of less than 4 thousands of a millimetre. HL2024 Constant Flow Regulators are manufactured in the Netherlands. The manufacturing process takes place under supervision of Kiwa Netherlands and is regularly audited in order to ensure constant quality. Kiwa s opinion: The products are assessed according to the BRL-K635 assessment criteria Flow limiters and meet Kiwa s high requirements both in terms of the product as well as their manufacturing process. It has become evident to us that the HL2024 products have been developed considering the user and are therefore extremely user-friendly. Kiwa Netherlands Kiwa Netherlands is the leading authority for the certification of pressure independent flow regulators (and non-pressure independent flow restrictors). Kiwa Netherlands has been running a complete and operational certification scheme for flow regulators for the past 15 years and earned worldwide respect for its technical expertise and for its global auditing and certifying services. Although HL2024 Flow Regulators look simple, the technology within the HL2024 product line is complex. The products deliver a constant flow that changes little over a broad pressure range. The deviation from the standard flow is the smallest we have ever registered. All in all, these are products that the manufacturers and distributors can be rightfully proud of. 2017 HGP International, the Netherlands www.hl2024.com info@hl2024.com last update: 28 May 2017 En 4 / 22

HL2024 Pressure Independent Flow Regulators The only flow regulator certified for pressure independence in the world. The balancing valve is shaped from high precision manufactured spring steel. It is flexible yet strong and makes up half of the flow regulating principle of HL2024. The steel is custom-manufactured to an extreme precision of thousands of millimetres. The mechanism of the balancing valve and the housing instantly reacts on pressure differences, resulting in a constant flow. The second inseparable part of HL2024 is the housing, made of a high grade engineering plastic that ensures continuous and precise operation. The housing is injection moulded to the lowest possible tolerances. This moulding process is continuously being monitored and fine-tuned if necessary. This guarantees continuity of quality and performance. Two custom designed strainers protect and hold the HL2024 Flow Regulating mechanism. Larger openings at the bottom strainer ensure that no particles can accumulate inside: most particles stay on top. Particles that do come in, also come out. In production, samples are continuously and extensively tested to ensure pressure independence and quality consistency of the products.
