The silicate fireproof board composite air duct has the characteristics of non-combustible A grade, the air duct itself has a certain sound absorption effect, high compressive strength, corrosion resistance, good tightness and long service life, etc.

There are many benefits to doing insulation. First of all, heat preservation literally means maintaining temperature. This temperature does not only refer to heat, but also cold air. Insulation can reduce energy loss, save energy and protect the environment, and can also isolate air. Isolating the air prevents oxidation, which increases the life of the duct.

The phenolic composite air duct has good thermal insulation, which can greatly reduce the heat dissipation loss of the air conditioner, which reduces the equipment capacity of the central air conditioning system.

Pre-insulated duct cutting machine
VENTECH has China top advanced Pre-inulsated duct cutting machine.VDCM cutting machine is special for PIR/Phenolic duct sheet cutting. It can process duct sheet includes Kingspan, P3, etc. Machine design and highligh:

1. Installation problem of air duct support and hanger
Problem analysis:
(1) The length of the main and main pipes in the ventilation pipe installation system exceeds 20m, and there is no fixed point to prevent swinging;
(2) The leakage length of the screw of the support and hanger is inconsistent.

1. Thin steel plate
Sheet steel is the main material for the manufacture of ventilation ducts and components. Plain sheet and galvanized steel are commonly used. Its specifications are expressed as short side, long side and thickness. The thickness of commonly used thin plates is 0.5×4mm, and the specifications are 900mm×1800mm and 1000mm×2000mm.

This post deals with ducted air conditioning. Below we will discuss the main points to consider when choosing the appropriate ducted air conditioning. We present the best ducted air conditioners.

The application of thermal insulation materials in the construction industry is customarily divided into two categories: inorganic matter (divided into board, block, slurry or fiber according to shape) and organic matter (including thermosetting and thermoplastic).

1. Before installation, ensure that the basic engineering has been completed
The installation of the air duct must be carried out after the completion of these basic projects; the appearance quality inspection should be carried out before installation, and the dust on the inner and outer surfaces and the sundries in the pipe should be removed.

△ Metal air duct installation requirements
(1) Air duct extension and hoisting. First of all, according to the specific conditions of the site, select two reliable hanging points on the beam and column, then hang the chain or pulley, and bind the air duct firmly with hemp rope. When lifting, when the air duct is 200~300mm above the ground, stop hoisting, carefully check the stress point of the chain or pulley and the rope binding the air duct, whether the rope buckle is firm, and whether the ce

We are living in a world where adverse climatic change has resulted to extremely high levels of global warming. These effects have not spared the mankind, animals, fish, plants, and non-living things.
