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.
Application advantages
-
Quick and easy installation.
-
The gaskets are factory-installed without play to ensure their proper seating when connections are made.
-
This allows accurate mounting of fittings without the risk of breaching the seal or air leaks.
-
An environment-friendly Installation method which requires no silicones containing toxic solvents that could evaporate into the ductwork.
-
The system can be installed in all weather conditions.
-
Temperature resistance: -30˚ to +100˚C.
-
Maximum operating vacuum: up to 3000 Pa.
-
Maximum operating pressure: up to 5000 Pa.
-
Internal and external manufacturing control.
-
An aesthetic finish which is particularly important for exposed systems.
