Liquid Thermal shock test chamber
Three Zone Thermal Shock Test Chamber
Thermal Shock Test Chamber
Liquid Thermal Shock Test Chamber,Cold and hot impact machine can be used to test material structure or composite material, in an instant by extremely high temperature and extremely low temperature continuous environment can endure degree, in order to in the shortest time test commits any heat bilges cold shrink caused by the chemical changes or physical damage. Applicable objects including metal, plastic, rubber, electronics, pv, solar... And other materials, the products can be used as a basis of improving or reference.
Significant reductions in fluid usage make liquid thermal shock affordable
Purchasing a liquid thermal shock chamber needs close consideration of the long term operating costs. The specialized liquids used can easily evaporate, causing the loss of thousands of dollars of fluid per year, if not properly contained. Liquid-to-liquid thermal shock testing is typically conducted to apply very strong, repetitive thermal stress to test pieces. It can model a product's ability to withstand thermally-induced size changes, crack resistance, hermetic integrity, and changes in electrical properties. This form of testing provides a very rapid temperature shock recovery of conditions, and it can significantly reduce testing time by requiring shorter soaks and less cycles. The liquid thermal shock chambers have been built to meet the demanding test req uirements, which has become a defacto industrial standard for semiconductor devices.
Tunnel oven/conveyor oven
Precision Vacuum Oven
Electrically heated tunnel oven
GRANDE electric heated tunnel ovens are based on a mature and time-tested system with a 10 year proven record of reliable round the clock production.The design is flexible and energy efficient and is built for decades of continuous use.The ovens are suitable for variety of products,ranging from buns to bread,cakes,moon-cakes and pastries.The tunnel ovens are manufactured in two basic versions,depending on the desired temperature range:Normal temperature up to 250??(482�F�) or high temperature up to 500??(935�F�).
Features & Benefits
Energy saving technology
GRANDE tunnel ovens are built with super insulating material that ensures that very limited heat escapes from the ovens resulting in the exterior being relatively cool.The exterior is made of stainless steel and our ovens are known throughout the world of their advance technology and energy efficiency.
Heating
The tunnel ovens are heated by the tube elements with double heating spirals.They are specially made for each oven to maximize the heat control and reliability of the elements.On average,we use 12 elements per meter of oven.The elements,placed on the top of the oven chamber and below the belt,are easily accessed from the side.
Turbo Zone
From some products,especially when baking with tins,the use of air circulation from turbo fans in combination with radiant heat is suitable.In such cases the oven is equipped with turbo zones.In a mesh belt oven,the hot air is forced through the belt and in a solid steel belt oven the hot air is blown horizontally along the zone.Turbo zones allow for the baking time to be reduced and lower temperatures used.With the adjustable fan speed the optimal turbo effect can be reached.
Steam system
In ovens equipped with a steam system the first part of the oven contains steam spread boxes made out of the highest grade of stainless steel.Valves with indicators are used to adjust the proper flow of steam.
Oven Control System
The PLC touchscreen is designed to be easy to use and give the best possible overview and control.Apart from temperature regulation and oven control,the touchscreen also comes standard with recipe handling,alarms,log function and Internet connectivity.
Belt Driving System
A frequency converter controls the speed of the driver motor,and the robust belt driving system provides optimal reliability and exact baking time.Long ovens and ovens for heavy products are fitted with double drive system,each with its own motor.
Belt conveyor ovens
The lowest cost and most common type of conveyor oven,belt conveyor ovens are extremely versatile and best suited for relatively light loads.In addition to standard wire mesh belts,Teflon coated fiberglass reinforced belts are also available for temperatures up to 500??(935�F�).These belts are non-marring and therefore well suited for handling coatings or finished products.
