Depending on the needs of each laboratory, it is possible to choose the most suitable furnace in order to optimize the energy expenditure in accordance to the casting rings quantity that is usually preheated.
The range begins with the HP-25 (2,5 litres capacity), an adequate option for reduce production A laboratories.
It continues with the HP-50 (5 litres capacity), adequate for medium level production.
The HP-100, with 10 litres muffle volume represents the highest capacity model, recommended for high production laboratories.
HP family muffle chassis is entirely made of stainless steel, heat degradation resistant material and easy to clean. It also has an excellent finish.
The muffle is made in ceramic material with healers wrapped along the upper, lower and on both sides. This way, there is a uniform interior distribution of temperatures. The exterior sides of the muffle are thermally insulated by zirconium silicate, probably the best thermal insulator used in industrial processes.
Gas flow inside this has been carefully studied. There is an air inlet at the door and a ventilation pipe at the back, both with calibrated sections. This way air inside the muffle is renovated without reducing thermal efficiency of the oven for producing temperature differences.
A practical socket allows the synchronised operation of the oven together with an extraction unit. Automatic disconnection can also be programmed between "I59 C and 8509 C. When temperature is over 8509 C, the control automatically disconnects the power supply.
Magnetic closing system is easy simple. A safety sensor detects door opening, and disconnects heaters while it is opened.
The Smoke Extractor R-030125 is an interesting attachment to the HP Preheating Furnaces. Installing this device, you succeed in getting rid of furnace gases generated in the in a continuous and smooth way. It is completely made of stainless steel and its installation is easy.
If it is connected lo the MESTRA HP furnaces socket, the extractor ranges from 759 to 850% as programmed by the user. If it is connected lo another socket it runs continuously.
