Cold & Cryogenic Insulation – Cryogel® Z

Introduction to Cold & Cryogenic Insulation – Cryogel® Z

Aspen Aerogel’s Cryogel® Z is an exceptional insulation for cryogenic and sub-ambient applications in the oil and gas processing industry and other industrial appliances. Cryogel® Z flexible blankets feature unique silica aerogel with a factory-applied vapour barrier. It has the lowest k-value of any widely used cryogenic insulation material, reducing thickness by 50% to 80% compared to other available cryogenic insulations.

Features of Cryogel® Z

  • Delivers maximum thermal protection in the range of -270⁰C to 90⁰C.
  • Factory-applied vapour barrier to resist water vapour and moisture from penetrating through the insulation and freeze at cryogenic temperatures.
  • Easy to wrap and insulate practically any equipment.
  • Extremely low thermal conductivity (k-value) reduces heat gain and liquid boil-off.
  • Minimal weight and thin profile reduce insulation thickness by 50% - 80% compared to other cryogenic insulations.

Applications of Cryogel® Z

Cryogel® Z is ideal for all industries, such as Oil & Gas Processing Industry for

  • LNG
  • LPG
  • Ethylene
  • Ammonia
  • Refineries and others

Liquification Processes for

  • Nitrogen
  • Hydrogen
  • Oxygen
  • CO2 and others

Piping, Equipment and Systems such as

  • Cryogenic Piping & Pipelines
  • Cryogenic Storage & Vessels
  • Chilled Water Systems
  • Distillation Towers
  • Regasification Systems
  • Cold Evaporators and others

Key Benefits

EXCELLENT THERMAL PERFORMANCE

Extremely low thermal conductivity (k-value) promotes five times better thermal performance compared to other insulation products for improved efficiency and energy savings.

LONG TERM INSULATION SOLUTION AND ASSET PROTECTION

Cryogel® Z hydrophobic nature and additional vapour barrier prevents Corrosion Under Insulation (CUI), minimizing the requirement for equipment inspection and maintenance.

THIN PROFILE

Equal thermal resistance with minimal thickness is ideal in a space-constrained environment.

ZERO PERMEABILITY TO WATER VAPOUR

Factory-laminated vapour retarder provides moisture protection, prevents damage from condensation and enhances process control to any insulation system operating at cryogenic temperatures.

QUICK AND EASY APPLICATION

Readily available in blanket forms that is easily cut and shaped to fit all equipment and pipings.

SHIPPING AND WAREHOUSING SAVINGS

Material volume savings, minimal site storage, and simplified logistics.

FIRE RESISTANT

Offers protections against cold splash, pool fire, and jet fire

ENVIRONMENTALLY SAFE

Landfill disposable, shot-free, with no respirable fiber content.
