MARINE System – Ventilation Duct & Equipment

ABOUT COMPANY ALNOR® Ventilation Systems Ltd. started its business activity in the year 1994 as the manufacturer of spiral ducts. The young and dynamic team quickly ensured the position of the leading manufacturer of round ducts in Poland to the company. In the year 2004, the company moved to the modern facility in Wola Mrokowska nearby Warsaw, owing to which the assortment was extended to include the rectangular duct systems and a number of ventilation accessories. The dynamic organisation, the excellent working conditions, the modern machine park and innovative enterprises cause ALNOR to be...

ROUND DUCT AND FITTINGS COST-EFFECTIVE VENTILATION Considering how high the cost of air processing can be and how rapidly markets are growing, ventilation systems are supposed to meet high requirements. It is necessary, therefore, that ducting systems be airtight enough to keep running costs at reasonable levels. To address this issue, Alnor Ventilation Systems Ltd. has developed a new comprehensive SPIRAL® system. AIRTIGHT DUCTING SYSTEM SPIRAL® is a well-proven system of spirally wound quick-connect ducts and fittings with factoryinstalled EPDM rubber gasket. The gasket ensures a tight and...

KEY ADVANTAGE The gasket adheres closely and tightly to the duct wall. BENEFITS OF USE • Quick and easy installation • Factory-installed gasket, with no loose components,ensuring proper adherence to the duct after joining. • With fittings fixed tightly, no risk of leakage. • Environmentally friendly, no need for silicones, which contain toxic solvents that may penetrate the duct. • Installable in any weather conditions. • Resistant to temperatures from -30˚C to +100˚C • Supports negative pressures of up to 3000Pa • Supports overpressures of up to 5000Pa • Internal and external production control....

For ventilation systems that need to be resistant to high temperatures, the SPIRAL® system can be delivered with silicone gasket that supports continuous temperatures from -70˚C to +150˚C and temporary temperatures from -90˚C to +200˚C. SPIRAL® system round ducts and fittings have the hygiene certificates: a) HK/B/1652/03/2007 for those made of aluminium sheet b) HK/B/1652/01/2007 for those made of galvanised or stainless steel sheet SPIRAL® system round ducts and fittings with gaskets are certified by SITAC for tightness class D – certificate No. 0103/07 All SPIRAL® system components are tested...

PRE-INSULATED DUCTS AND FITTINGS IZOL®system INTRODUCTION We would like to introduce our offer for IZOL®system preinsulated ducts and fittings. Pre-insulated ducts and fittings, designed for both indoor and outdoor applications are called IZOL®system. IZOL®system consists of inner and outer galvanised wall, and insulated with mineral wool. Nominal dimension of diameter 100 -500 mm always defines inner ducts diameters and fittings diameters. Insulation Two type of isolation are used: • 10 insulation – nominal insulation thickness is 10 mm, strictly corresponds to inner and outer SPIRAL®system...

min. - max. diameter Ødnom min - Ødnom max [mm] 157 Above tolerances are standard dimensions for IZOL®system and ensure complete closure of the air flow. Diameters made of thinner sheet are provided with external corrugation: t = + 0,2 mm. Ød is up to standard PN-EN-1506:2001 min. - max. średnica Ødnom min - Ødnom max [mm]

INNER AND OUTER DIAMETER OF DUCTS AND FITTINGS AIRTIGHT DUCTING SYSTEM Inner ducts and fittings of pre-insulated IZOL® system are the SPIRAL® system. SPIRAL® is a well-proven system of spirally wound quick-connect ducts and fittings with factory- installed EPDM rubber gasket. The gasket ensures a tight and permanent connection between SPIRAL® system components. The system is available in a full range of sizes, from 080 to the largest The SPIRAL system meets the requirements of tightness class D (certificate No. 0103/07) as defined The high quality and efficient, factory-in stalled rubber gaskets...

PRE-INSULATED DUCTS AND FITTINGS IZOL®safe-system INTRODUCTION We would like to introduce our offer for IZOL®safe-system pre-insulated ducts and fittings. Pre-insulated ducts and fittings, designed for both indoor and outdoor applications are called IZOL®safe-system. IZOL®safe-system consists of inner and outer galvanised wall, and air in the middle. The distance between inner and outer walls is maintained by means of special spacer. Nominal dimension of diameter 100 - 250 mm always defines inner ducts diameters and fittings diameters. Insulation Two types of insulation are used: • mineral wool...
