Construction: The ovens are available in five sizes ranging from 75 to 686 liters. They feature an inner casing made of corrosion and heat-resistant stainless steel, and an outer casing of sheet steel with a stoved epoxy paint finish. The design includes no contact between the inner and outer casings, optimized insulation with 150 mm thick glass fiber, and a special gasket for efficient operation and thermal stability. The door is hinged on the right and secured with a robust two-point fastener.
Heating: The ovens use stainless steel sheathed tubular heating elements activated by a solid-state relay for wear-free switching.
Internal Fan for Air Circulation: All models include fan circulation to speed up heating and ensure even temperature distribution. The centrifugal blower is located at the top, shielded by a stainless steel baffle, and recirculates heated air throughout the
oven.
Exhaust Air and Fresh Air Supply: Fresh air is pre-heated before entering the chamber through an access vent. An adjustable valve controls the exhaust air flow through a 60 or 80 mm diameter vent, depending on the model.
Temperature Control and Safety: Temperature is monitored by a J thermocouple and controlled by a microprocessor-based controller for high accuracy. A second electronic controller provides additional safety with an adjustable upper limit.
Equipment: The ovens come with fixed shelving for easy loading and unloading, with one shelf for the XHT075 model and two for others. A 20 mm diameter access port is standard on the left-hand wall.
Applications: Suitable for burning, degassing, pre-heating, hardening, hot air sterilization, and various industrial tests.
Performance: The ovens can reach temperatures up to 500°C with a fluctuation of less than ±0.2°C and spatial variation of less than ±2.5°C at 200°C.
Technical Specifications: The document provides detailed dimensions, ventilation, shelving, and electrical supply information for each oven model. Options include additional safety thermostats, digital timers, and various accessories.
Factory Options: Customizations such as stainless steel casing, special colors, additional thermocouples, and air extractors are available.
