As process-related trace heating, a KLETTI **adhesive technology heating hose** ensures a homogeneous temperature profile from the pre-melting system to the application nozzle. The system is specifically designed to maintain the predefined viscosity window precisely in the liquid state and to reliably prevent thermal shocks or temperature drops. This precise temperature control consistently prevents the adhesive from prematurely degrading or solidifying inside the line. Deposits on the inner walls of the hose are prevented, downstream application systems remain protected against blockages caused by cured residues, and maintenance-related downtimes during shift changes are minimized. --- An overview of our range of hotmelt hose solutions. ----------------------------------------------------- Here you will find our preconfigured system solutions for the **transport of hotmelt adhesives**. - **Splash-proof hotmelt hose (IP65), dustproof and washable** - **Highly impermeable hotmelt hose for hand guns** - **Reliable hotmelt hose with replaceable material hose** - **Silicone-free, flexible heating hose for automation technology** [Request your individually manufactured heating hose now](https://www.kletti-gmbh.de/kontakt/) Frequently asked questions about our heating hoses for adhesive systems (FAQs). You ask. We answer. ----------------------------------------------------------------------------------------------------- ### Which common adhesive systems and application systems are KLETTI hotmelt hoses compatible with? Our heating hoses are characterized by a high degree of compatibility. Since we configure existing hose systems and their mechanical and electrical connections precisely, **KLETTI hotmelt hoses** fit **almost any existing adhesive system** on the market – including as a precisely fitting and cost-effective replacement solution for systems from global market leaders such as Nordson, Meier or Robatech. Compatibility is primarily based on the **precisely fitting connection interface**. We convey almost all common hotmelt adhesives. If your system uses a highly specific, chemically very aggressive specialty adhesive, we will check this in advance. In the event of incompatibility, we will rule out compatibility and, if desired, develop a **custom-made heating hose**. ### Can KLETTI heating hoses heat the adhesive inside the hose? No. Our **heating hoses** are designed solely as **trace heating**. This means that the hotmelt material must already be fed into the heating hose in a liquid and correctly temperature-controlled state. The hose's process-related function is to maintain this temperature precisely over the entire distance to the application point in order to prevent cooling and solidification. Active heating of cold, solid material inside the hose does not take place. ### How flexible and temperature-resistant are the heating hoses in sub-zero temperatures or under high dynamic loads? Thanks to our high level of vertical integration, we are not bound by rigid standards. Especially in highly dynamic applications, such as **use on multi-axis industrial robots**, where hoses are exposed to extreme mechanical loads due to constant movement, we take special design precautions. This drastically increases service life compared with static lines. We adapt the ***hotmelt*** **hose** to your ambient conditions and the technical data of the adhesive used (e.g. electrical connection, operating pressure, low-pressure or high-pressure applications). For example, if you need a **silicone-free heating hose** that remains absolutely flexible during dynamic robot movements in winter operation, we precisely tailor the materials accordingly. We also vary the thermal output individually. Through specialized heating conductor winding, we can configure heating hoses without difficulty so that they are designed for continuous operation at 200 °C instead of the usual 160 °C. We also manufacture every **hotmelt hose** precisely to the length you require. ### What advantage does a hotmelt hose with a replaceable inner core offer during ongoing operation? In adhesive technology, thermal overload, extreme adhesive residues or mechanical damage inside the hose can cause bonding or defects. With a standard heating hose, the entire costly system, including the heating conductor, sensors and insulation, would have to be replaced in this case. With **our version with a replaceable inner core**, you only replace the inner material hose. Although the initial purchase of this system is somewhat more expensive, the investment quickly pays off. Kletti will provide you with a **like-new hose promptly, saving you considerable replacement part costs in the long term** and **minimizing the downtime** of your production system. The matching inner cores are always available from us as separate accessories. --- ![](https://miyagi-kan.toujou.website/_assets/processed/11kSKxzVyBA8tfsRx2UUgVKzWveFbT0Ve243oJ5Yif4/q:85/w:433/h:289/fn:Y3NtX1Blb3BsZV9QQ19hMzRlOWNjN2E0:t/cb:c0a8e9855c0f282bfb74e02cc86d7fac5803fbd4/bG9jYWw6L2ZpbGVhZG1pbi9CaWxkZXIvQmlsZGVyX1RlYW1fdW5kX1VudGVybmVobWVuL1Blb3BsZV9QQy5wbmc) ### **Does your industrial system have special requirements regarding pressure, temperature and geometry?** Whether you need an extremely short custom hose for confined installation spaces, are looking for a special connector fitting for an older system model, or need to implement a specific temperature profile for highly viscous specialty adhesives: We develop and manufacture your individual custom solution.
