Overview
The CR Duct System offers a complete, pre-insulated system for heating, ventilation and air-conditioning.
CR Ducts and CR Bends consist mainly of glass, sand, and soda. CR Ducts and CR Bends both possess patented aluminum CR Foil on inner and outer surfaces, which provides a condensation barrier. The CR Duct System is built to the standard dimensions of the European ventilation market.
CR Ducts are standardly mounted round but, through use of the CR Transformer, can be made rectangular when necessary.
Applications
The CR Duct System can only be used for indoor installations.
CR products are not to be used for kitchen exhaust.
Local rules and regulations are to be recognized when installing any CR products. When calculating pressure drops, please use tables and diagrams for corresponding sheet metal products. CR products will be slightly lower.
Certifications
The CR Duct System has been certified through SP Certification, the Swedish governing body for CE certification and accreditation. The matrix above represents tests and certifications that have been passed and awarded by SP Certification.
