Year of construction: 2020, condition: new, 7 "Touch Panel The large color touch panel looks aesthetically and is comfortable and intuitive to use. You will set all important parameters on it. Memory of 20 programs with 10 events It is possible to save up to 20 programs and activate up to 10 consecutive time-temperature events arranged in the heating curve. This is especially needed for more demanding processes. Information on gas / oil consumption The consumption is calculated based on the burner settings. This feature will allow you to estimate the cost of a given cycle, plan consumption and check personnel. Dual-channel recorder of USB cycle parameters Each furnace is equipped with a recorder that records all firing parameters, including two temperature channels - like in an airplane black box, on a USB flash drive. The system also enables the analysis of monthly / daily statements, including media consumption and performance. Each start of heating, opening the door, can be recreated, a few years back. Such a dedicated option is not offered by any manufacturer. It is a system developed from scratch by our programmers Automatic smoke exhaust chimney The chimney can be programmed to open a few minutes before the end of the firing in order to smoke the chamber. It can be remotely controlled from the panel, it does not need to be done mechanically as in most structures. Minute forecast until the end The cycle has started, how long will it end? calculating the heating dynamics, we will count it and show on the display how much longer it will take. To open it, just pull the door. The lock has adjustable pressure of the door, to close it just push it, the lock will catch the door and automatically pull it back. In order to minimize the effect of heating the hall when opening the door, a hood is installed above the door to remove some of the heat to other places. The MTS system was created to provide a real reading of the temperature of the furnace chamber. Standard measurement is based on one temperature measurement which is often wrong.MTS is a system of many sensors located in the outermost places of the chamber. The multi-zone heating system ensures a firing quality that has been so far unique. Each normal oven has only one heating zone and only one temperature measurement! Bwjdsfz U Tqopfx Albsn The multi zone heat system supports up to 8 independent heating zones in one oven. Each heating zone has as many as 3 temperature sensors! When there are temperature differences between zones, they are automatically equalized! The system helps to combat the problem when elements of different material thicknesses enter the furnace.
