Heating&cooling time has been reduced by 60 to 75%(compared toourconventional products) and a silicon free type ovenforproductionlines that support multi power sources is addedtotheline-up. 
- Time for heating and coolingoftheproduct has been improved by 50% or more comparedtoourconventional products and the objective is toreduceproductiontakt time.
- Time for attainingthehighesttemperature has been reduced by up to 1/3 (at noload,compared toour conventional products) and time fordecreasingtemperature inthe bath, by 50% (at no load, compared toourconventionalproducts). Work efficiency can begreatlyimproved.
- The damper willautomaticallyopenwhen operation finishes, which requires notroublesomemanualoperation. Also, the optional 10-step variable fancontrolfunctionallows you to set to any wind amount youwant.
- A silicon-free eco oven withitsdoorpacking of Viton® fluoroelastomer. (DNG610V/810V)
- This product supportsmultipowersources. It can be operated simply by connecting to 200to240Vpower source.
- Four-foldoverheatpreventivefunctions (automatic overheat prevention, heaterroomoverheatprevention, overheat prevention in the bath,andtemperature fuse)assure the optimal safety. The productalsofacilitates the selfdiagnostic function, the alarmhistorymonitoring function, the keylock function and anover-currentelectric leakage breaker.
- Abundantfunctions(externalcommunication that supports RS485/FORWARD,external alarm,time-up,output on the logger) allow upgrading of thesystemaccording tothe specific application.
