You have finally established that the lab requires a brand-new furnace. There are various points that one must look into when buying a brand new electrical resistance heated furnace. This post gives you a guide to purchase the appropriate furnace for your use. Here are elements of great importance that needs to be prioritized. First you need to make up your mind on what is going to be the running temperature that is going to be made use of frequently. It is obviously possible to get a furnace that can span a broad temperature range mostly for purposes of a laboratory but then aspects of price must be considered. One should research further and the user might accept that a lot of their processes need just a certain maximum temperature, that is more economical and practical.
It is important that you have the clarification between kiln and furnace. These terms are capable of being used in interchangeable manner in a wide sense. To be more particular the term kiln is made use of in ceramics and cement field while the word furnace is utilized in general heating, metallurgical applications and metal characterization. Therefore, on the basis of the industry the work furnace or kiln might mean a similar unit.
The furnace size matters. When buying a brand-new laboratory furnace one is supposed to prioritize if there is a possibility of expansion taking place in the future. A furnace might be ordered with particular working dimension for present projects however future plans might need a larger unit. Having in mind time frame, cost restrictions, it is wise to take into consideration purchasing a large unit during the first purchase that you make. It can happen that upon doubling the volume of working the cost might increase in a drastic manner or might be not as much as you can never be so sure unless a person obtains a price quote. In case upcoming future projects require a higher unit of temperature than a number of things need to be evaluated. The cost that comes with a temperature increase a bigger size unit as a result of the insulation need and also one is supposed to take into account the current normal running temperature parameters that regards to maintenance issues temperature uniformity and consistency in comparison to a higher unit of temperature.
Furnaces are made to run using a uniformity and high efficiency at the operating temperature that is specified. It is once again not a wise decision to buy a furnace that uses high temperature when in actual sense you require a low temperature one as this is going to bring about an operational issue with process control. Furnace geometry should be looked into. A box unit is best when it comes to loading samples in an operation batch and at the same time a tube unit is best for a progressive application like material characterization or gas conditioning testing that happens inside a process tube.
