1.Rubber-plastic sponge insulation process
① First, wipe the surface of the air duct clean, wipe off the dust and accumulated water on the surface and let it dry;
② Cut the insulation material according to the size of the air duct, and cut the material according to the regulations of pressing the long side to the short side;

The concept of ventilation systems consists of ventilation ducts and all the components and equipment necessary for their function. They consist of all the components through which the air circulates, such as ventilation pipes, accessories, ventilation shafts and ducts, mufflers, fans, air conditioning devices, fire dampers and other closing devices against the transmission of fire and smoke and closing devices against smoke transmission (smoke dampers) as well as their connections, fixings, ins

1.Selection principles and precautions
First of all, the flow rate and pump head of the highest operating condition must be satisfied, and the working state point of the water pump should be in the high efficiency range. The flow and head of the pump should have a margin of 10-20%.

Using a pre-insulated duct CNC cutting machine will definitely improve your duct making efficiency. A pre-insulated duct CNC cutting machine is a computerized cutting machine that cuts fast and accurately.

1. Unable to connect: Because the air duct cannot be connected, it has many advantages such as tight connection joints, good quality of joints, light weight of joints, material saving, simple construction process, saving man-hours, easy to achieve full mechanization, automatic construction, low construction cost and many other advantages, so it has been widely promoted.

1.Cooling water circulation system
The outlet temperature of the cooling water of the condenser can generally reach above 37°C. The high-temperature water is cooled by the cooling tower to the inlet water temperature required for cooling the condenser of the chiller, and then sent to the chiller for recycling through the cooling water pump.

HVAC systems (or heating, ventilation and air conditioning systems) are responsible for heating, cooling or circulating air in all types of buildings, both residential and industrial. These systems usually have a considerable network of ducts to transport and distribute the air, so it is essential that these are well insulated for everything to work properly.

Using a pre-insulated duct CNC cutting machine will definitely improve your duct making efficiency. A pre-insulated duct CNC cutting machine is a computerized cutting machine that cuts fast and accurately.

This method is formed by improving the rubber and plastic insulation of traditional galvanized steel air ducts. The core is to improve the cutting method of rubber and plastic insulation boards. The four sides of the air duct are cut from the whole board, and the four corners are cut and connected at 45° to ensure that the The four sides of the insulation layer are at right angles to reduce the bonding seam.

1. Temperature Controller

The temperature controller is used for the control or protection of the unit. When the temperature reaches the set value, the switch automatically cuts off (or turns on) the circuit. In our products, the temperature control is often used, and the temperature of the water tank is used to control the start and stop of the unit. There are also some like antifreeze that require the use of a temperature controller.

As has been seen, in a distribution of ducts you can find some accessories that are part of it and condition its behavior. There are both for circular, oval or rectangular ducts.

Using a pre-insulated duct CNC cutting machine will definitely improve your duct making efficiency. A pre-insulated duct CNC cutting machine is a computerized cutting machine that cuts fast and accurately.
