Laboratory Chamber Furnace - CWF ATMOSPHERE RETORTS FOR CWF FURNACES

A retort can be used for various heat treating processes requiring a controlled inert or reactive atmosphere, e. g. to prevent oxidisation or to enhance surface hardness. The A105 retort, which incorporates a silicone rubber seal, can achieve low oxygen levels. Manufactured in either NiCr alloy (Inconel) with a maximum operating temperature of 1100 °C or 314 grade stainless steel with a maximum operating temperature of 1050 °C.

The A105 retort is sealed by a removable front opening insulated door fitted with a silicone rubber seal. Gas inlet and outlet connections are easily accessible at the front. Oxygen levels down to 30 ppm are achievable. A105 retorts for CWF furnaces are fitted with a 3 mm thermocouple gland through the centre of the door. The retort and furnace must be ordered together as the furnace is modified to allow it to be used with, and without, the retort. The A105 retort can be used in combination with the laboratory gas safety system for safe use with hydrogen.

Please note
- Heat up rate is measured to 100°C below max, using an empty chamber
- Holding power is measured at continuous operating temperature
- Maximum power and heat up times based on a 240V supply
- The uniform volume is smaller than the total chamber volume
