Heaters

Panel Space Heaters / Enclosure Heaters

We manufacture heaters in different ratings and sizes for enclosures, panels, cabinets & switchboards.

The heaters have the following characteristics:

• Insulation level: 2 KV for 1 min.
• Standard power tolerance : ± 3%

Construction:

• Body made of anodized heat sink grade extruded aluminium.
• High quality Kanthal resistance material is used as heating element.
• Mica is used for optimum insulation.
• Resistance element and insulation are held tight in between extruded aluminium body and squeezed.

Advantages:

• Close tolerance of electrical rating.
• Quick and uniform heating.
• Fast dissipation of heat into air.
• Withstands much higher degree of mechanical shock and vibration.
• Very good insulation resistance even in extreme humid conditions.
• Elevated body for easy passage of heat directly to air, without heating panel body.
