Are your heaters cleanroom compatible?
Yes. Nor-Cal’s closed-cell silicone heater jackets have a 150°C breakdown half-life of 25 years, and are class-100 cleanroom compatible.
Are your heaters UL listed?
Nor-Cal Heater controllers are UL listed and CSA approved. Our Gasline heaters are UL Listed, and our standard thermal jackets are fitted with UL-listed connectors. Custom jackets for specific agency compliance (CE, NEC-427, etc.) are also available.
Can I use my existing controller with your heater jackets?
Yes. Nor-Cal heater Jackets integrate with standard controllers.
Can I wash heater jackets?
Jackets must be unplugged from heater supply and cool, before being wiped-down with damp cloths. Jackets must be fully dried before re-installing. Do not immerse jackets in water or cleaning solutions.
Do your heaters heat the valve plate?
Nor-Cal’s heaters do not directly heat the throttle plate in butterfly or gate valves, but thermal transfer through the valve will keep the plate warm as well.
Does Nor-Cal make custom-designed heater jackets?
Yes. Nor-Cal can help you design a heating system for your application. In addition, our trimmable jackets allow for up to 1 inch (25mm) to be trimmed to meet your specific requirements and ensure 100% line coverage.
How long does it take for heaters to stabilize?
The time required for stabilization depends on three factors:
The thermal conductivity and of the material being heated (Aluminum, Stainless, etc.)
The amount of material to be heated
The energy consumed by the process gasses and the ambient room temperature
For example, a large Stainless foreline running a cool process in a cool room will take longer to heat than a short Aluminum elbow running a hot process in a heated room.
What is the accuracy of your heater controllers?
Nor-Cal PID Thermal controllers can maintain a +/- 2°C setpoint temperature. They are remotely configurable for setpoint, temperature ramp, over/under temperature alarm, and system performance through RS232 or RS485 serial communication.
What is the hottest / biggest / smallest / heater you provide?
Nor-Cal provides closed-cell silicone heater jackets for applications up to 200° C. Clothbound, fiberglass insulated options are available for applications up to 400° C.
What types of products can Nor-Cal heat with thermal jackets?
Nor-Cal has standard jackets for tubing, flanges, valves, elbows, forelines, Y-joints, conical reducers, ball valves, and gate valves. Some Nor-Cal valves have integrated heaters, and passive jackets are used for insulation.
What voltages can I run heaters from? (Alternate question: What is required to run heaters?)
Heaters are standard at 120V and 240V, and are interconnectable up to a 10-Amp or 1200 Watt circuit.
When do I need a heater?
You need a heater if process gasses condense on cool system components. Keeping system components heated keeps condensable particles from depositing in your system until they can be properly removed by a particulate trap.
