PKRC gastight chamber furnace with retort up to 950 / 1100 °C

The better PKR. With internal atmosphere circulation for precise temperature distribution

For this furnace, the same applies as for PKR—a precisely defined protective atmosphere protecting the surface of the charge from unwanted changes, relatively low gas consumption, a variant with argon, nitrogen, or forming gas, and so on. However, the PKRC furnaces also have even better temperature distribution than PKR furnaces thanks to internal atmosphere circulation.

For the PKRC furnaces, you can also pay extra for a retort made from of type Inconel material that can handle a temperature 150 °C higher than a stainless steel retort can. We can also adapt PKRC furnaces to nitriding furnaces at your request.

Subject to technical changes.

Note: After our experience with previous applications, we know that the service life for a standard retort (an internal gastight vessel) used for a maximum temperature of 950 °C is low (it depends on its endurance period for the temperature, but is roughly on the order of hundreds of hours). If you wish to operate a plant regularly at a temperature of around 950 °C, then we recommend equipping it with a retort made from of type Inconel material.

Standard equipment

Ht205 controller (30 programs of 15 steps each)
heating coils wound on ceramic tubes outside the working area of the furnace
door sealing
manually controlled ventilation and suction flaps for cooling outside of the retort
manual door opening to the side
limit unit
automatically controlled protective atmosphere inlet for one gas type (without vacuum pump)
vacuum pressure gauge for vacuum control in the retort
vacuum pump connection inlet
G½” adapter for connecting cooling collar rubber hose
thermistor for temperature control flange, signalling the presence of coolant in the retort collar
overpressure valve at the retort gas input point with pressure 4-6 mbar
ammeters to check the status of the heating elements (number depends on the number of stages involved in heating)
type ‘K’ thermocouple
contactless solid state relays for silent operation
limit end-switch for safe opening of the furnace

Optional accessories available at additional cost

spare retort of refractory steel
vacuum pump for extraction of the atmosphere + necessary controlled forced cooling
charge thermocouple and Ht40 temperature display unit
controlled forced cooling (according to input cooling curve)
three-channel digital temperature recorder
optimization of the temperature field to meet DIN 17052-1 ΔT20 °C norms in the inner useable furnace (in empty furnace at Tmax)
calibration of the measurement loop
EIA-485 or LAN interface
HtMonit EV set (contains software + interface)

Atypical accessories:

retort made of Inconel material and cst propeller of fan
other gas services based on customer specifications (more gas, more flow, etc ...)
atypical stand
