Kingflex
Premium elastomeric closed-cell foam and industrial thermal barriers designed for chilled water systems and cryogenic environments.
Global energy dynamics, HVAC efficiency demands, and modern condensation mitigation parameters.
In modern industrial and district heating/cooling systems, chilled water systems operating between 4.5°C and 7°C are critical. Effective insulation prevents atmospheric thermal gain and safeguards HVAC infrastructures against moisture-driven degradation.
If the surface temperature of chilled water pipelines falls below the surrounding ambient dew point, moisture condenses. This invites mold growth, compromises structural finishes, and causes Corrosion Under Insulation (CUI).
Determining target chilled water insulation thickness relies on relative humidity, ambient dry-bulb temperature, and thermal conductivity. Calculating this accurately saves millions in energy losses over plant lifespans.
Unrivaled production scale, raw material vertical integration, and world-class testing infrastructure.
Located in the green-building materials center of Dacheng, China, Kingflex Insulation Co., Ltd. integrates research and development, manufacturing, and direct sales. By sourcing raw materials locally, utilizing automated foaming lines, and employing strict quality assurance, Kingflex provides reliable, cost-effective insulation systems worldwide.
Reference thickness guidelines to control condensation on cold pipelines (Operating fluid at 5°C, based on NBR/PVC closed-cell foam).
| Pipe Size (Nominal Diameter) | Mild Conditions (27°C, 50% RH) | Normal Conditions (30°C, 75% RH) | Severe Humid Conditions (32°C, 85%+ RH) |
|---|---|---|---|
| DN15 to DN32 (1/2" to 1-1/4") | 9 mm | 19 mm | 25 mm |
| DN40 to DN80 (1-1/2" to 3") | 13 mm | 25 mm | 32 mm |
| DN100 to DN150 (4" to 6") | 19 mm | 32 mm | 40 mm |
| DN200 to DN300 (8" to 12") | 25 mm | 38 mm | 50 mm |
| Flat Surfaces / Large Ducts | 25 mm | 40 mm | 50 mm |
*Note: The table is a general calculation guideline. Severe environments like tropical zones or underground plants require custom calculations using Kingflex technical support software.

The industry is transitioning toward healthier, low-VOC green buildings. Materials must meet strict fire protection standards (such as BS 476 Part 7 Class 1, ASTM E84, and UL94) while retaining low thermal conductivity over time. Additionally, integrated vapor barriers and self-adhesive pre-formed systems are growing in popularity to lower installation costs.
Engineered products verified by international standards agencies.
Our insulation materials pass testing by global authorities, including BS 476, CE, REACH, ROHS, UL94, and ASTM. Each batch is traceable back to the production run, ensuring consistent quality for your projects.
