1. The shrinkage of the PP-R pipe must be less than 3% when it is hot-melted, and the installation must meet the technical requirements of the manufacturer;
2. The pipes must be casing through the wall, De25 and De32 use PUC70 casing; De40, De50 and De63 use PUC110 casing; De75 and De90 use PUC133 casing;

he installation position of the air conditioner host should be convenient for maintenance, and it will not affect its use function, especially pay attention to heat dissipation. In the case of multiple hosts in the computer room, all the host computers must take over the direction and the operating surface in the same direction;

1. Confirm that the on-site civil structure has been completed and that there is no large amount of water used for construction.
2. Confirm that the professional construction of pipes, electrical, fire protection, etc. above the air duct is basically completed, so as to avoid a large number of cross-operations from damaging the thermal insulation.

The biggest difference between the inner insulation air duct and the outer insulation is that the insulation and the air duct are designed together to save the time of doing insulation separately. The construction period can be reduced. It is more suitable for engineering projects with high construction period requirements. It can effectively shorten the construction period and save time.

We see a lot of air ducts with a layer of insulation on the exterior. Why do we need insulation? In fact, there are many benefits to heat preservation. First of all, heat preservation literally means maintaining temperature. This temperature not only refers to heat, but also air conditioning. In particular, the air ducts connected to the central air conditioner (which can generally be seen in large supermarkets) must be insulated.

Fabric-based ducting has more to do with air distribution rather than acting as an air-conditioning conduit, fabric duct can make the distribution of air to be more even due to its base material, polyesther.

Ducts are conduits used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air in the particular area or building. Ducts also deliver ventilation air as part of the supply air. Air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort. Ventilation ducting is use in a wide variety of setting including industrial, high rise building, car park basement, kitchen, warehouse and etc

A few years ago, central air conditioning and fresh air systems were only high-end home improvement options in some villa areas, but now they have become the choice for many families, especially in northern cities.

On Jan 14th, 2022. Our machinery sales department went to our factory in Yingde, Guangdong, China. Wish everyone that is reading this passage would come and join us on the tour in the future. We will show you our hospitality, and professionalism of over 15 years HVAC manufacturing experience.

This year's Spring Festival holiday in China is from January 31 to February 6, and workers at VENTECH factory have a few days off. Our sales department and administration department will be on a public holiday with the country starting tomorrow.

Now there are many ventilation duct materials on the market, so how should we choose?
