Nozzle band heaters were designed as an economical mica band heater in nozzle and narrow width size. The intent was to create ready stock to be supplied to the customers without any loss of time and can be made at a reasonable price. They can also be made in various sizes according to the customer's specification and requirement. They have been tested over time thoroughly and have proved to be a very good performer.

SPECIFICATIONS:

• Cost effective performance via light gauge and shell design.
• Protection from short circuit and increased safety via high temperature insulated electrical leads.
• Effective heating up to 800° F provided by Mica insulation and NiChrome heating elements with 31 to 46 watt per square inch.

DESCRIPTION

These Heaters are designed primarily as economical mica band heaters in nozzle and narrow width sizes. The idea is to make available from ready stock so that customers get the supply without loss of time and these can be made available at fairly low prices. Other sizes can be made available on request. These heaters have been thoroughly tested over the period of time and have proven to give a good performance.

FITTING INSTRUCTIONS

• No air gaps should be present between nozzle and heaters.
• Too loose heaters should never be used.
• The clamping screws need tightening up after initial heating up period.
• The plastic material on the heater surface should be removed by increasing the temperature to the melting point of the material and not by drying or hammering.

*Kerone recommends watt density under 55 w / in2 for normal plastic processing.

For normal plastic processing Kerone recommends Watt Densities under 55 W/ in²
