From materials to finished products, all within one company
Unlike conventional heat exchanger manufacturers that rely on externally sourced gaskets, VISER leverages more than 20 years of rubber compounding expertise to design and manufacture gaskets in-house.
This vertical integration strengthens quality control from material formulation to finished products, ensuring reliable and consistent thermal management performance.

The Strength of Vertical Integration
Reduced Gasket Lead Times
Integrated production from materials to finished products
- Compound design, vulcanization molding, post-processing, and finished-product inspection are all performed at a single site.
- An in-house production system that minimizes reliance on outside processes, curbing lead-time variability and securing supply stability.
One Accountable Quality System
A single, unified quality accountability system
- A single quality-management system covers everything from raw material properties to finished-product inspection.
- When an issue arises, root-cause analysis through improvement is completed in-house for a swift response.
Materials Engineered for Your Application
Materials developed to customer specifications
- In-house development of dedicated compounds optimized for chemical resistance, temperature, and other operating conditions.
- In-house R&D capability extending to specialty materials for extreme conditions such as high temperature and high pressure.
R&D Center Overview
The VISER R&D Center is an integrated research organization that carries out both rubber compounding R&D and heat exchanger performance improvement simultaneously
from material development to finished-product verification, all under one roof.
Rubber Compounding R&D
- Developing new EPDM/NBR/HNBR compounds
- Researching improved heat, chemical, and pressure resistance
Gasket Design Optimization
- Designing Clip-on/Glue-on structures
- Developing aramid-reinforced EPDM for high-temperature, high-pressure steam
Heat Exchanger Performance Verification
- Testing heat-transfer efficiency (LMTD) and pressure rating (28 bar)
- Accumulating performance data to support AHRI LLHE certification
