Industrial Drum Heaters

Nicropad Industrial Drum Heating Systems are engineered for efficient, uniform, and controlled heating of viscous and temperature-sensitive materials stored in standard industrial drums. By applying heat directly to the drum surface, these systems facilitate faster melting, improve material flow, and help maintain the required process temperature with reduced heat loss.

Nicropad offers two primary drum-heating solutions: Metallic Drum Heaters for robust, high-capacity applications and Flexible Drum Heating Pads for lightweight, adaptable surface heating.

1. Metallic Drum Heaters

Nicropad Metallic Drum Heaters are designed for reliable and uniform heating of standard industrial drums. The heater consists of two equal semi-cylindrical sections, connected by hinges on one side and provided with a secure locking arrangement on the opposite side. This construction allows convenient loading and removal of drums while ensuring effective heat transfer during operation.

Construction & Mobility

The standard metallic drum heater is manufactured with a 3 mm thick mild-steel (MS) inner sheath and a 1 mm thick MS outer sheath, providing a durable and rigid construction suitable for industrial environments.

Heavy-duty castor wheels can be provided for convenient movement of the heater to the required operating location.

Heating System

The standard heating arrangement incorporates six flexible heating pads, with three heating elements installed in each half of the heater. The elements are strategically positioned to provide uniform heat distribution across the inner sheath and, consequently, the drum surface.

Approximately 75 mm thick thermal insulation is provided between the inner and outer sheaths to minimize heat loss to the surrounding atmosphere, improve energy efficiency, and maintain a comparatively lower outer-surface temperature.

Depending on the application and required operating temperature, alternative heating technologies such as tubular heating elements or mineral-insulated (MI) heating cables can also be incorporated.

Both vertical and horizontal drum-heater configurations can be supplied to suit specific process requirements.

Power Rating

The standard configuration consists of six heaters rated at 750 W each, providing a total heating capacity of 4.5 kW. The system can be suitably configured for connection to a three-phase electrical supply.

Higher heating capacities can be provided depending on the application, with configurations available up to 9 kW.

For applications requiring faster heat-up and improved temperature uniformity, an optional 1 kW base heater can also be incorporated.

Temperature Control System

For accurate and reliable temperature regulation, the drum heater can be supplied with a suitable electrical control panel incorporating a digital temperature indicator-cum-controller and PT100 temperature sensor.

The control panel can either be supplied as a separate control unit or conveniently mounted directly on the drum heater, depending on installation and operating requirements.

1. Flexible Drum Heating Pads

Nicropad Flexible Drum Heating Pads provide a lightweight, versatile, and energy-efficient solution for heating drums containing viscous, semi-solid, or temperature-sensitive materials. The pads are designed to wrap closely around the drum surface, providing direct and uniform heat transfer.

Construction

The heating elements are manufactured using high-quality nichrome resistance wire and suitable insulating and protective materials. Depending on the operating temperature and site conditions, the heating pads can be manufactured using:

• Fibreglass cloth
• PTFE (Teflon)-coated fibreglass cloth
• Silicone-coated fibreglass cloth

The heating element is suitably insulated with fibreglass yarn or an equivalent high-temperature insulating material.

Efficient & Uniform Heating

The highly flexible construction enables the heating pad to conform closely to the drum surface, minimizing air gaps and ensuring efficient heat transfer. Uniform distribution of the heating elements helps provide consistent heating across the drum circumference.

The heater is backed with approximately 40 mm thick thermal insulation to minimize heat loss to the atmosphere and improve overall energy efficiency.

Flexible Configurations

Depending on the required heating capacity and process conditions, a single heating pad or multiple heating pads can be installed on each drum.

Nicropad Flexible Drum Heating Pads are available in different wattages, sizes, and configurations to suit specific heating requirements. Temperature regulation can be achieved through an integrated thermostat, digital temperature controller, or dedicated control panel.
