How to deal with low temperature environment for spiral duct fan
Spiral duct fan in the lower temperature environment, is bound to be affected to a certain extent, so how should we deal with this situation? The first is to do a good job in keeping warm, choose insulation materials, but the selection of insulation materials is also required, the following spiral duct manufacturers will tell you how to choose.
Second, the specification of thermal insulation materials should meet the requirements of the air duct system, not only that, but also meet the design requirements of air duct. Thermal insulation materials should have product quality certificate and other certificates.
Through the insulation material, to effectively protect the air duct, so that its use in winter will not be damaged. For the clean air duct, the refractory closed cell rubber plastic sponge insulation material is generally selected, and the non combustible aluminum foil glass wool board is used for the smoke exhaust duct. These two materials are widely used, and the heat preservation performance is also better.
Before wrapping the spiral air duct with thermal insulation materials, the thickness of the glue should be uniform, and there should be no glue flowing. When the thermal insulation materials are paved, the bonding can be effectively guaranteed, and the bonding is tight, and there will be no hollowing, and there will be no air duct exposed outside.
