Nitigura Jacket
Products
What is "Nitigura Jackets"?
They are thermal insulation covers that are removable and prevent energy loss and heat transfer from high-temperature equipment.
Nitigura jackets are used for heat insulation, thermal insulation, and heat shielding for valves, boilers, injection molding machines, and other equipment that consume large amounts of energy. Just applying our Nitigura jackets to your epuipment reduces the heat transfer and bring you great benefits in electricity and fuel bills.
- Energy Saving
- Safety Improvement
Conserve enegy by preventing heat transfer from pipes and valves!
The reasons of the choosing
-
From raw material to finished product
We handle everything from material selection to equipment measurements, sewing, and installation.
We also use our own heat-resistant insulation jacket products, dust-proofing, and waterproofing to meet various temperature ranges from low to high temperatures.
Temperture Ranges and Material Options
The materials used in Nitigura jackets can be selected for various temperature ranges from low to high temperatures according to the purpose of use and application.
No Binder, Adhesive or Phenolic Resin Used
