Ship launching airbags are to be constructed of a cylindrical body and two conical heads (one at each end). Ship launching airbags with lots of advantages, such as easy to operate, time saving, saving investment safety, etc.
Major Strengths of Ship Launching Airbags:
High level of safety: Equipped with a reliable safety valve, our airbags can stand the maximum pressure up to 4 times that of the operating pressure.
Good air tightness: Pressure decreases less than 10% for a period of 24 hours.
Long lifespan: It is guaranteed that our airbags can sustain their designed operating pressure for 3 years.

Aluminum plate&bar coolers feature a wide variety of thermally efficient internal and external fin patterns. Fins are laid between aluminum braze sheets and fitted with header and face bars. The assembled unit is placed into one of our modern brazing furnaces where precise control of time and temperature produces a unified core. Manifolds designed to meet each customer's particular piping requirements are welded into place to complete the cooler. We can also supply cores when manifolds already exist or must be fitted in the field.
These strong, compact, light-weight coolers are ideal for both on- and off- highway markets. We can also supply the complete cooling package consisting of a combination of coolers, fan guard and motor.
From small individual coolers to large complex engine cooling systems, Better-Tech can design and manufacture the heat transfer solution that's right for you. Our engineering team is continually developing additional fin geometries to improve heat transfer efficiency so we can meet or exceed your expectations.
