Diffusion Pump Heaters

Replacement diffusion pump heaters for all major manufacturers. Diff-Therm Platen Heaters provide 20% more heat than OEM heaters. Flat, smooth platen surface assures uniform, efficient heat transfer. DIP performance provides process improvements with higher throughput. Our one piece design (instead of the 3 piece OEM design) provides easier and faster installation.

Pump Heater Brands/Types of Heaters

Varian or Agilent - Diff-Therm Platen Heaters

Edwards Vacuum - Diff-Therm Platen Heaters

Leybold Vacuum- Watt-Flex Cartridge Heaters

CVC - Diff-Therm Platen Heaters

Veeco - Diff-Therm Platen Heaters

Cooke Vacuum - Diff-Therm Platen Heaters

Diff-Therm Accessories

High-Temperature Manganese Nickel Conductor Wire (1000°F Max)- Recommended as lead wires for connections to header terminals for high-temperature areas. Use with ceramic bead insulators below.

Ceramic Bead Insulators- Can Withstand temperatures to 2000°F

High-Temperature Nickel Ring Terminals (Stak-On type)- Good for connections in high-temperature areas.

Diff-Tranz High-Temperature Heat Transfer Compound for Temperatures to 1250°F (675°C) - A good idea for use with Ring heaters. Also good for mounting Platen heaters when contact between the heater and pump boiler plate is poor. Not recommended for cartridge heaters.

High-Temperature (850°F/450°C max) Insulated "A" Nickel Conductor Wire

One-Piece Assembly Simplifies Installation

Our platen heaters are one piece instead of 3 pieces (conventional tubular/crush plate design). Alignment and fit is never an issue

Leybold Diffusion Pump Heater
Watt-Flex® Cartridge Heaters 

Watt-Flex®  Cartridge Heaters are direct replacements for Leybold Vacuum Diffusion Pump Heaters.

The split sheath heater of the Watt-Flex is easily inserted into the heater tube at the base of the Leybold pump and can be provided with or without the mounting bracket used to secure the heater in place. When energized, the heater legs expand to make snug contact with the bore for maximum heat transfer. When de-energized, the heater contracts for easy removal. This eliminates the chance of having to drill out the heater, saving time and energy.
