Hoses are used in the most diverse areas of the agricultural industry. The requirement: Long service life during seasonal work supporting continuous loads is an important characteristic for the operator . Ease of  handling is an additional benefit that our hoses can offer. That means: The product properties of the hoses must be adapted to the application, because:  Especially during intensive work phases, such as sowing and harvesting, farmers must rely on the continuous functionality of their machines and attachments.

Essential hose properties for the agricultural sector

Hose properties such as flexibility, microbe -, UV- and ozone-resistance are crucial for use within agriculture and at the same time determine the service life of the hose. During the sowing and harvesting periods in spring and autumn, a temperature drop can occur, so the property of the cold flexibility of a hose is very important. At the same time, the user has to rely on the hose operating at high temperatures during summer. The range of high-quality NORRES hoses includes high-performance hose solutions made of Pre-PUR^® and flexible PVC, whose properties are specially adapted for use in agriculture.

Flexible Quality – Soft-PVC Hoses

The portfolio of soft PVC hoses with particular suitability for the agriculture sector includes the NORPLAST^® PVC 379 GREEN SUPERELASTIC and the NORPLAST^® PVC 389 SUPERELASTIC / SUPERELASTIC PLUS. Both types of hoses are very resistant to alkalis, acids and chemicals - making them ideal for distributing insecticides and fertilizers. The NORPLAST^® PVC 389 SUPERELASTIC has a life-prolonging abrasion protection thanks to an external abrasion protection via external helix, which saves floor space, prolongs service life makes it easy to use. Both hose types are made of high-quality and cold-flexible soft PVC and are smooth inside. In addition to fertilizer and insecticide distribution, these hoses are also ideal for irrigation or transportation purposes. The embedded in the wall plastic spiral allows an outstanding lifetime and has proven itself in demanding applications.

High mechanical stability – Pre-PUR^®

An alternative to soft PVC is the patented premium polyurethane (Pre-PUR^®) used by NORRES. Thus, for example, the AIRDUC^® PUR 351 FOOD and the AIRDUC^® PUR 355 FOOD have increased abrasion resistance and high mechanical stability. Properties that ensure that the service life of a hose increases significantly. Due to the premium polyurethane Pre-PUR^®, the hoses do have a very good low temperature flexibility. Hose types, such as the AIRDUC^® PUR 355 FOOD and AIRDUC^® PUR 351 FOOD have an outstanding interior smoothness and are thus optimized for flow.. The advantage for agricultural machinery: The transported goods are transported gently. The AIRDUC^® PUR 355 AS is recommended for the pneumatic transport of cereals or for the promotion of seeds and fertilizers, since here too the abrasion resistance and thus a long service life play an important role. The AIRDUC^® PUR 355 AS is also suitable for the pneumatic transport of combustible dusts and bulk solids in accordance with TRGS 727 and ATEX 2014/34 / EU.  

NORRES hoses made of Pre-PUR^® and flexible PVC with particular suitability for the agricultural sector offer, due to their properties, a long and reliable service life and safety during operation. They are especially suitable for a high throughput of abrasive substances and even at high flow speeds.
