ProTemp S 300W

The JBL ProTemp S 300W is a high-power heater designed to stabilize water temperatures in large aquariums up to 400 liters. Thanks to its 300W output, a heavy-duty protective plastic grid, and 2mm thick quartz safety glass, it ensures rapid and efficient heating even in larger volumes.

Key Features

• Guard Grid: Plastic safety cage prevents fish from touching the hot heating element directly.
• High Capacity: Designed for massive aquariums up to 400 liters, fresh or marine.
• Dry-Run Protection: Automatically shuts off if removed from water or exposed to air.
• 2mm Quartz Glass: Excellent thermal and physical resistance to withstand heavy in-tank stress.
