Source: Dalton Electric Heating Co., Inc.Single piece assembly platen heaters that are manufactured from high-quality tubular heating elements are swaged under 50 tons of pressure into a grey iron casting. The unique swaged assembly increases the performance of the heater and is available as a direct original equipment manufacturer (OEM) replacement for several leading vacuum diffusion pump brands including CVC Products, Cooke Vacuum, Edwards High Vacuum, Leybold, Torr Scientific, Varian/NRC and Veeco.

Dalton Electric Heating Company produces a wide range of direct replacement diffusion pump heaters for leading vacuum pump brands. Their Diff-Therm Platen Heaters outperform other OEMs as they provide for better heat transfer rates and exhibit a longer heater life. Increased performance is realized due to the following benefits:

• Under "full power," their heaters produce 20 percent more heat than other OEM heaters.
• The platen heater has a flat, smooth surface to assure uniform, efficient heat transfer rates.
• The increased power and ideal surface conditions increase pump throughout supporting higher vacuum system processing rates.

Their replacement heaters provide increased dielectric density and uniform heat distribution that increases pump throughput. The simple one-piece assembly design also facilitates heater installation.
