If our stock units do not meet your application needs,
Watlow can manufacture RAYMAX heaters to your special
requirements. For made-to-order heaters, specify the
following:
Heated width and length. Three-phase panels must have
width divisible by three.
Total wattage of each panel.
Exact voltage and phase. A five percent variation in
voltage at the oven will cause a 10 percent variation
in power.
Zoning. Indicate dimensions and wattage of each zone.
Mounting legs or mounting studs, if desired. For studs,
give number and location, or indicate standard location.
Terminal location if non-standard.
Terminal box or wire raceway, if required.
Supplying a drawing with an order or request for quotation
can be very helpful in clarifying design information.
