DS Heaters' strip heaters, often considered component heaters, are a simple way of using surface area to transfer heat effectively. A fairly inexpensive way of heating surfaces or small areas, strip heaters are an excellent solution to meet any budget. If strip heaters are used as a radiant heater, they can have fins to maximize surface area and heat transfer to the air.

Construction

DS Heaters' Mica Strip Heaters are constructed by winding a nickel-chrome resistance ribbon around mica insulation and encapsulating it in a stainless steel sheath. They are available in an extensive variety of sizes and shapes, with options for holes, notches, and cut-outs. A range of threaded terminals, wire lead options, and terminal boxes provide great flexibility for field wiring. These heaters are ideal for plastic processing applications and for any application where heat is required on a flat or curved surface.

FEATURES

•

Heat up time is fast to provide a quick response to control input

•

The flat inner resistance ribbon generates a broad area of overall heat to put the heat source close to the work

•

Quality assembled winding and spacing of ribbon ensures maximum heat transfer and heater longevity

•

The Mica insulation also withstands high voltage temperatures, resist moisture, and remain immune to most chemicals

Termination Options

Standard Fiberglass Leads Termination

This Mica Strip heater has Fiberglass Leads that exit through outside surface.

Metal Braided Fiberglass Leads

This Mica Strip heater is designed with Metal Braid leads that exit through outside surface

High Temperature Quick Disconnect Plug

This provides the simplest and fastest way to apply power to band heaters. This assembly eliminates all live exposed terminals and electrical wiring that can be a potential hazard to employees or machines. Can be provided on heater length of 40 mm or more. Recommended for heater capacity up to 2.5KW.

Horizontal Post Terminals

This Mica Strip has Post terminals at the same end across the width. The Post Terminals are protected with Ceramic Cap.

Vertical Post Terminals

The Post terminals are in the same line of this strip heater run length ways. The Post Terminals are protected with Ceramic Cap.

CERAMIC BAND HEATERS

Ceramic Band Heaters are very flexible and can be made in large widths and one-piece construction for easy installation, eliminating heat losses between narrow bands and sharply reducing labor costs in installation.
Before installation & during operation, the surface of the barrel and ceramic band heater must be clean and free from all contaminants that might liquefy under heat and find their way into the heater elements, carbonizing and becoming conductive. The smallest amount of contamination can cause electrical shorts creating heater failure.
Tighten the Allen bolt until the serrated edges become firmly in direct contact with the barrel to get uniform contact. Do not over-tighten to the point where serrated edges begin to collapse and thrust outwards. Unlike all other types of band heaters, Ceramic Band Heaters work on conduction and radiation principles and do not require the same clamping force.
To prevent overheating and heater failure, adequate temperature controllers should be installed. Thermocouples must be kept free of contaminants and checked for good responses to temperature changes. A bad thermocouple can destroy an entire heating zone.
Keep all electrical connections properly protected to avoid accidents.
Never perform any type of service on heaters without disconnecting all electrical power.
Incorrect wiring is a common cause of heater burn-out.
Qualified personnel should do the electrical wiring of heaters.
