How to Order
To order your stock RAYMAX heater, specify:
• RAYMAX 1120
• Quantity
• Watlow code number (from Watlow Heater's Catalog)
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.
