Miyawaki QH / QAG Q-Plus Jacket Thermal Insulation Cover
Manufacture: MIYAWAKI Inc.
Model: QH / QAG
Features
Customized manufacturing available
No matter how complex, this product can be manufactured in any shape to fit the device or component for thermal insulation.
Top class insulation performance
Uses material with extremely low heat conductivity.
Depending on the materials used, the safe operating temperature can reach a maximum of 1000℃ (1832°F).
With a material suitable for the application and manufacturing using three-dimensional forming, there are no gaps for heat to leak out of and this results in top class insulation.
Environmentally friendly design with simple attachment and detachment
With a structure that uses hook-and-loop fasteners and other such things, this product can be attached and detached by anyone, and can be used repeatedly.
The QAG model is made from high-quality material that can be used long term in harsh conditions both indoors and outdoors.
High water-repellent properties
The aerogel type (QAG model) has high water-repellent properties.
Typical applications
Perfect for thermal insulation on all elements of any steam system, including lines, valves, boilers, and steam traps.
