Brewmaker Heating Tray for fermenter

The top face of this tray is 28.5cm square, which is perfect to take a 5-gallon container, and it is tough enough to take the weight without sagging! 

It is strongly made from flame retarded injection moulded polycarbonate, is splash resistant and being rated at 25 Watts is powerful enough to raise the temperature by about 5C whilst still remaining economical to run.
