|For over thirty years, Process Technology has been the leading manufacturer of electric immersion heaters, heating and cooling coils, controls, instantaneous heaters, liquid level controls, over-temperature protection systems and accessories. Our product line is among the most comprehensive and diverse available, with both standard and custom configurations to suit your specific application.Product Features and Benefits:SUPERIOR CHEMICAL RESISTANCE: Inert to most aqueous acid, alkaline, anodizing and pickling solutions up to 212°F (100°C).
RUGGED CONSTRUCTION: Heavy wall fluoropolymer (PTFE) covered stainless steel element reduces permeation and eliminates the need for gas purge systems. Guaranteed 100% pinhole free.
OUTSTANDING PERFORMANCE: Low watt density design (10 watts/square inch, 1.5w/cm2) for long service life.
EVEN HEATING: Flat, low profile bottom design for even heating and varying liquid levels. (This configuration not recommended for electroless chemistry.)
CORROSION RESISTANT HEAD: Vapor tight, flame retardant polypropylene terminal enclosure with 3-foot (.9m) flexible PVC liquid tight conduit.
