nail-free and glue-free waterproof structure patented technology

Mcwell Patented technology

The "nail-free and glue-free waterproof structure" patented technology completely eliminates leakage hazard.

Industry factory owners have long suffered from the following problems

Real Industry Case 1:

A person in charge of Suning at relevant matter is furious about the automatic opening vent produced by a certain factory that had been put into use for over two years. He said: "Water leaks from this batch of electric lighting smoke ventilators frequently, which affect normal usage. This problem could't be fundamentally even after repeated maintenance. The dilemma was, either remove and replace them at a great cost, or keep them in place at the great cost of constant annoyance and operation interruption".

Real Industry Case 2:

DFSK used smoke vent skylights from another brand for its phase one factory building. After usage for half a year, it was discovered that there was frequent water leakage in the building. Through careful investigation, automatic smoke vent windows was identified as the source of the problem, but after the problem still could not be addressed even after performing numerous maintenance. Since the problem often delayed production, DFSK had no choice but to remove the troublesome ventilators and replaced them with Mcwell's smoke ventilation system with "nail-free and glue-free waterproof structure".

Why are electric smoke ventilators prone to leakage?

Structure of traditional electric smoke ventilator

Structure of traditional electric smoke ventilator

The traditional electric smoke ventilator is generally composed of four pieces of independent broken bridge aluminum profile and solar panels.

Rainwater seeps into the room through the corner gaps of the window sash.

Rainwater seeps into the room through the corner gaps of the window sash.

The gaps at the corners formed by the four pieces of aluminum profile (referred to as corner gaps) are exposed to natural elements outdoors but connected indoors. water will inevitably enter the room through the "corner gaps"

Waterproof method of traditional electric smoke ventilator

The traditional method adopted by smoke vent manufacturers is to use gel-like substances such as silica gel to seal the inside of the "corner gaps" where rainwater is unavoidable, so as prevent rainwater from entering the room through the gap.

Why is there a water leakage hazard in the silicone bonding gap?

1
As a chemical material,gel-like substances such as silica gel are prone to aging and cracking.
2
The components sealed with gel-like substances will shift and displace, expand with heat and contract with cold, leading to cracks in the gel
3
The gel-like substance is applied manually, and the quality of application is not consistent because of human factors such as varying technical level and sense of responsibility of the workers.
Gel-like material ages and cracks easily, leading to water leakage hazard, but unfortunately they are not repaired just as easily. Repeated leakage and maintenance of the ventilator affect normal production and operation, and the impacts eventually pile up to a serious burden for the owners. This is why ventilators are removed and replaced in many facilities across various industry even with the substantial costs and troubles involved.

How to fundamentally resolves the hazard of water leakage from
electric lighting smoke ventilator?

PATENTED PRODUCT

Patented Product

The "nail-free and glue-free waterproof structure" patented technology ensures reliable and long-lasting waterproof performance of natural ventilator, and fundamentally resolves the hazard of leakage common in the natural ventilator industry.

INTEGRATED STRUCTURE

Integrated Structure

The window sash and window body of the smoke ventilator with "nail-free and glue-free waterproof structure " do not require any silica gel, self-tapping nails, drilling or rivets; and are all integrated holistically into the waterproof structure.

xxxx

No Leakage Hazard

Let the inner aluminum of the broken bridge aluminum become a whole structure, the window sash profile no longer connects the indoor and outdoor, the indoor and outdoor are separated by the integral flooding plate, and the rainwater entering the window sash is discharged outside through the integral waterproof plate, which fundamentally resolves the hazard of water leakage from smoke vent.

Maintenance cost

The hazard of water leakage exists but this problem cannot be fundamentally resolved even after repeated maintenance. Such kinds of ventilators not only have short service life, but their poor performance affects normal production on rainy or snowy days, and often have to be removed and replaced at substantial costs and troubles.
