1400°C 1500°C 1600°C RHF Chamber Furnaces

This comprehensive range is available at 1400, 1500 and 1600°C with four popular capacities of 2.9, 7.8, 14.8 and 35 lites (1600°C version has a maximum capacity of 37.5 litres). Powerful silicon carbide heating elements provide fast heat up rates, typically 40 minutes to 1400°C depending on the model.

Silicon carbide heating elements are ideally suited to the rigorous firing cycles often required in laboratory furnaces. These elements withstand the stresses of intermittent operation and give long life at elevated temperatures. Furnaces using these elements are designed with excess power to ensure that aging is easily corrected and heating performance is maintained. The average life of the elements may be several years, depending on operating temperatures and conditions. They are easy to replace when either hot or cold and require only the removal of the furnace back panel (the RHF 16/37 requires the removal of two side panels).

Two types of insulation are used: Hard wearing refractory brick around the doorway and in the floor to give resistance to abrasion and spillage. Lightweight ceramic fibre is used in all other areas to ensure energy efficiency and fast heating/cooling. The RHF 16/37 is insulated totally by hard wearing refractory brick.

A parallel opening door allows full and easy access to the chamber and keeps the hot face insulation away from the operator during loading/unloading.
