Laboratory Furnaces Carbolite RWF seriesThese furnaces are designed for light to medium duty where rapid thermal response is a primary requirement. The powerful free radiating coiled wire elements are situated in the sides and top of the work chamber which is constructed from rigidised low thermal mass insulation.
A hard, dust-free ceramic hearth provides a robust base for the furnace charge and the combination of low thermal mass insulation and high power heating elements gives a very rapid heatup rate from ambient to 1100°C in as little as 10 minutes. Rapid cooling can be induced by opening the furnace door during cool down. Servicing is facilitated by the removable instrument panel and easy access to element modules and thermocouples through the rear of the casing.
A vertical counterbalanced door mechanism keeps the hot door insulation away from the operator when the door is opened. The control module is situated below the door and provides a variety of control options depending on the model chosen. All versions have digital display of temperature and a choice may be made between a simple PID controller or more sophisticated proqrammable controllers.
The standard control module options are:

Tube Furnaces CarboliteTube furnaces are ideal for gas analysis, materials testing, ceramic firing, continuous strip heating and thermocouple calibrations In these furnaces the resistance wire heating elements are wound directly onto an impervious ceramic tube, providing fast response rates. The work space is the maximum possible, with the thermocouple sited outside the work tube close to the element. A Eurotherm 91 PID digital controller is fitted to all furnaces; this controller simultaneously displays both preset and actual temperatures.
A choice of 900°. 1000° and 1200°C versions is available.

Economy Furnaces Carbolite ELF series 1000°CEconomy laboratory muffle furnaces with one-piece moulded ceramic fibre chamber and venting chimney. The heating elements are positioned in the sides and top of the vacuum-formed chamber, giving excellent heat distribution. A hard ceramic hearth tile is available as an accessory.
Temperature control options are either a CAL8000 analogue proportional controller with LED bar display or a Eurotherm 91 digital controller with full PID action and digital temperature display of both preset and actual values. Both svstems emPlov a tvPe K thermocouPle (NiCr/Ni/AI).
The furnaces have a short heat-up time and the low thermal mass insulation and double skin construction with air convection provides a low outer skin temperature. A safety switch disconnects the power when the door is opened .
