Cryogenic accessories
Heater, heater wires and cables from CryoCon
Heaters are needed to actively control a temperature inside a cryostat. They work best in combination with the temperature controller from CryoCon. To contact heaters and sensors in a low temperature environment, it is important to use special materials suitable for these temperatures. Good electrical conductivity paired with poor thermal conductivity materials are here the materials of choice, like phosphor-bronze.

Cartridge heaters CC-3039-001 & CC-3039-002
The cartridge heaters are available in 50 and 25 Ohm versions to match the heater outputs of all of Cryo-con’s temperature controllers. The Nickel-chromium resistance element assures even, efficient heat distribution. Efficient Magnesium oxide insulation is Silicon free allowing use in high vacuum systems.
Wire heaters CC-4039-011 & CC-4039-012
Wire heaters are a length of insulated Nichrome wire with crimped copper connectors on each end. Crimped contacts are used because of the difficulty in connecting to Nichrome. A heater is fabricated by wrapping the wire around a cylinder, being careful to heat-sink the wire over its entire length. Stycast epoxy is often used to provide a good thermal attach, especially at the ends of the wire. The wire is often folded over in the middle and wrapped bifilar style so that a strong magnetic field is not created when current flows. Wire heaters are available in 50 Ohm and 25 Ohm versions.
Nichrome heater wire CC- 3039-006
Single-strand Nichrome heater wire is recommended for the fabrication of heaters in cryogenic environments.
- AWG 32 (0.203 mm)
- 80% Nickel, 20% Chromium
