Given the high costs of air treatment and a boom in the HVAC sector, ventilation systems must satisfy very stringent requirements. As a result, it is essential to ensure that duct connections are sufficiently leak-proof to keep the costs of operation at economically viable levels. To tackle this problem successfully, ALNOR Systemy Wentylacji Sp. z o.o. has developed a new end-to-end SPIRAL®system.
The SPIRAL®system is a proven system of quick-coupled spiral ducts and fittings provided with factory-installed EPDM gaskets. The gaskets provide leak-proof and durable joints between SPIRAL®system components. The system components are available in a full range of diameters from Ø80 to Ø1250 mm. SPIRAL system meets the requirements of PN-EN 12237 for air tightness class D (Certificate no. 0103/07).
The high-quality of workmanship and factory-installed rubber gaskets enable easy and quick assembly of ventilation ductwork. Ductwork based on SPIRAL®system components guarantees long and leak-proof service life and requires no additional sealants.
An aesthetic finish which is particularly important for exposed systems.
