  • Maximum temperature: 1200ºC
  • Maximum continuous temperature: 1150ºC
  • The chamber is manufactured from a 98% Alumina material and is supported by lightweight low thermal mass ceramic brick.
  • The bricks are machined to carry spiral elements of Kanthal A1 material.
  • The chamber is equipped with a chimney for the removal of any undesirable gaseous contaminants.
  • For ashing applications, preheated air can be passed through the chamber and extracted through a large stainless-steel chimney. (Optional extra)
  • The removable “hot box” is mounted in a lightweight steel cabinet designed to use convected air to provide a cool outer skin.
  • In the interests of the operator, the door moves on a parallel link system and an internal spring counter balance system ensures ease of movement.
  • The entire cabinet is subjected to a seven-stage zinc phosphate anti-corrosion treatment and then a durable epoxy powder coat is applied.
  • Standard instrumentation consists of a digital set, digital indicate, dual display P.I.D. temperature controller with power limiting facility and the capacity to auto tune P.I.D values to the characteristics of your process.
  • This in turn signals a solid state, zero voltage-switching relay, causing minimal interference with other electronic equipment.
  • Platinum rhodium thermocouples.
  • A completely independent over temperature circuit protects the unit from over firing.
  • The unit is supplied in manual reset, which allows the unit to be operated unattended.
