Avasarala enjoys a unique distinction of having achieved space quality certification process for its processes and components with successful establishment of critical heat pipes for satellites. The products have found its way into satellites and a continued long term commitment from our clients testifies to the customer confidence. Avasarala supplies critical machinery for the space launch programs and other critical equipment. Avasarala has been actively associated with Space Sector since 1998 and has worked on a variety of critical and technologically challenging projects.   Products Heat pipes. Wave Guides. Mechanisms. Heat pipes Heat pipes typically provide a quick mechanism to transport heat from the spacecraft electronics and instruments to its radiators. These are two phase heat transfer devices circulating a working fluid such as ammonia that evaporates and condenses to transport heat. Heat pipes provide a highly energy efficient means to transport hundreds of watts of thermal energy across several metres. Heat pipes can be embedded within a honeycomb panel and bonded to the inner surface of the face sheets to achieve highly efficient heat removal. Surface mountable heat pipes with flanges attach to heat pipe panels to transfer heat from internal equipment to external radiator panels. The heat pipes have been successfully supplied for various satellite programs such as GSAT-3 (Edusat), INSAT-4A, INSAT-4B, INSAT – 4CR, CARTOSAT-2A, CHANDRAYAAN, EADS – EUTELSAT – W2M, AVANTI HYLAS, GSAT-4, OCEANSAT-2, RISAT, GSAT-5, GSAT-5/3E, GSAT-8, ASTROSAT, GSAT-12, SS LORAL, ETC., Supply of Space quality heat pipes of different cross-section & configuration for various Space Programmes.       Wave Guides & Mechanisms: Avasarala offers critical space grade Al section waveguides with critical dimensioning, shapes, with dip brazed flanges and silver plated internals.
