Used in

Common applications for CRYDOM
Industrial heating — Crydom 53TP series SSRs control resistive heating elements in furnaces and ovens, with zero-voltage switching to reduce electrical noise.
Plastics machinery — Dual Crydom SSRs (e.g., CC4850W2V) manage barrel heater bands and mold temperature controllers, providing independent control of multiple zones.
Packaging equipment — Panel-mounted Crydom SSRs switch motors and solenoids in high-speed packaging lines, offering long life and resistance to vibration.
Lighting control — Crydom triac-output SSRs (e.g., 21R940) dim or switch industrial lighting circuits, with finger-safe terminals for operator safety.
HVAC systems — Crydom SSRs regulate compressors and electric heaters in commercial HVAC units, with AC input compatibility for direct control from thermostats.
Water treatment — Crydom SSRs switch pumps and valves in water treatment plants, with SCR output for inductive load control and heat sink options for high ambient temperatures.
