High temp oven XHT model

 

PERFORMANCES:
The high temperature ovens are easy to use, having both functional and practical equipments, at very reasonable prices compared with furnaces.
All high temperature ovens are strongly ventilated for the accuracy and homogeneity of temperature in the volume.
Low thermal mass insulation materials and strong power rating have been used to achieve rapid heating.
    Why choose our XHT high temperature ovens ?
  • Rapid heating-up to 500°C
  • Temperature fluctuation: less than ±0,2°C
  • Temperature spatial variation: less than ±2,5°C at 200°C
They are suitable for a large number of applications: burning, degassing, pre-heating, hardening, hot air sterilization, tests... in many branches of laboratory and industry.

 

 
Our XF Vacuum ovens are used for any laboratory or industrial application.
These vacuum ovens enable heat sensitive materials to be dried at low temperature.
More stable samples can be dried at higher temperature up to 200°C or 300/400°C as an option.



A performance and maximum temperature only on our XF ovens:
■Primary vacuum
■Secondary vacuum
■Heating up to 200°C (300/400°C in option).
■Final vacuum of 10-6 mBar, depending on the vacuum pump used.
■Temperature time fluctuation: less than ±0,2°C.
 
HEATING QUALITY:
The tubular heating elements are sheathed, made of stainless steel, and ideally placed in the air blow. No-wear switching (solid state relay) is used for activating and desactivating the heating elements.
But our heating speed is not only done by our heating element. It is also achieved by our insulation. If the oven is well insulated, heat will be kept inside the chamber. Our quality of heating will reduce a lot the energy cost!

TEMPERATURE CONTROL & SAFETY:
Temperature sensor is a J thermocouple. The temperature is controlled by a precise microprocessor-based controller that provides a high accuracy and prevents the set temperature from being exceeded. The controller digitally displays continuously the set and actual values of temperature. An independant second electronic controller, with a second thermocouple, has an adjustable upper limit, giving a class 3.1 protection.

 
  • INTERNAL FAN FOR AIR CIRCULATION:
    All ovens are fan circulated. The air flow speeds up the heating time and also events the temperature distributionwithin the oven. The centrifugal blower is located at the top of the oven, shielded from the workspace by a stainless steel baffle.
    Air is draw into the fan from the top in the centre of the oven and passes over the temperature sensor and the sheathed heater elements.
    The heated air is distributed in the bottom of the oven through the whole width and then re-circulated by the fan.


    EXHAUST AIR, FRESH AIR SUPPLY:
    Through access vent, fresh air is provided and pre-heated before entering the chamber.
    A 60 or 80 mm diameter exhaust vent is provided with an adjustable valve to control the exhaust air flow.

 

 
EQUIPMENT:
Fixed shelving for convenient loading / unloading.
1 shelf is supplied for XHT075 and 2 for the other models.
A 20mm diameter access port with fiber cork is fitted as standard in the left-hand wall of the oven.
A wide range of factory-fitted options and accessories to meet your exact requirements...
