Copper Pipe Band Heater BRASS BAND NOZZLE HEATER SANGI ELECTRIC

SANGI ELECTRIC Brass Band / Nozzle Heater

SANGI ELECTRIC Brass Band / Nozzle Heater is an electric heater designed to wrap around brass tubes, providing heat to the outer surface of cylindrical parts. It is suitable for installation near nozzles and components of plastic injection machines as well as localized heating in industrial machinery.

This type of heater works on the principle of converting electrical energy into heat through resistive elements, transferring heat through the heater structure to the surface of the installed part, allowing targeted heating under appropriate temperature control systems.

When selecting a brass band heater, one should consider the outer diameter of the workpiece, installation area width, power requirements, voltage, and operating temperature to ensure proper adhesion to surfaces and efficient heat transfer.

Note: The confirmed catalog verifies the type of product and application for Brass Band / Nozzle Heater; however, there is no specific numerical data available for wattage, voltage, maximum temperature, and standard size of this brass item. Therefore, details must be verified before ordering.

Principle of Operation of Brass Band / Nozzle Heater

The brass band heater operates by utilizing electrical resistance elements that generate heat when supplied with electric power. The heat is then transferred through the heater to the surface of the workpiece it contacts.

Adequate heat transfer depends on the tightness of the heater's fit against the pipe or nozzle surface, contact area size, wattage, and temperature control during operation.

The heater should be clamped tightly to the workpiece as per manufacturer specifications and checked periodically for secure mounting. Loose installation may result in poor heat transfer and overheating of the heater.

Usage with Plastic Injection Molding Machine

A plastic injection molding machine uses a heating system to control the temperature of plastic during production. The band heater can be used as a heating component at the nozzle or other parts designed for this type of heater installation.

The selection of heater size must consider the actual installation position, as plastic injection molding parts may have different diameters and mounting areas.

The desired temperature depends on the type of plastic and production process requirements; therefore, it is advisable to use heaters in conjunction with appropriate temperature control systems and temperature sensors.

Usage with Tubes and Cylindrical Parts

In addition to injection molding applications, Band / Nozzle heaters can be adapted for cylindrical parts or tube systems requiring external heating when properly selected and designed to suit the medium inside the tubes and operating conditions.

For oil or liquid transfer systems, maximum temperature, safety of the medium, and installation compliance with system requirements must be considered. It should not be assumed that all types of heaters are suitable for every type of fluid.

Selecting Heater Size (Heater Dimensions)

Critical information for selecting Brass Band / Nozzle Heaters includes the outer diameter of the tube or nozzle and the width of the area requiring heating.

Required Dimension	Description
Inner Diameter (ID)	The inner diameter of the heater that must match the outer size of the part.
Band Width	The width of the heater along the tube axis.
Clamping Arrangement	The clamping and mounting device position arrangement.
Terminal Position	The terminal or wire exit position.
Installation Clearance	A clearance for installation and heater replacement.

Use drawings or measure the actual part size, especially when ordering to replace existing heaters in machinery.

Electrical Power and Voltage (Wattage and Voltage)

The electrical power of the heater should be proportional to the system's thermal load and the heating surface area. Watt density on the heater surface must also be considered to avoid abnormally high temperature accumulation.

The voltage must match the actual operating electrical system, and it is advisable to check manufacturer specifications before connecting the electricity.

Do not use a heater with different voltage or wattage without engineering suitability verification.

Temperature Control

The use of band heaters should include a temperature control system, such as a Temperature Controller, along with an appropriate temperature sensor. Choose the power switch device to match the current capacity of the heater.

In high-risk applications from abnormal overheating, install a separate overheat protection system outside the normal control circuit to prevent damage to machinery and workpieces.
