Grant heated circulators are ideal for use with Grant stainless steel and plastic tanks. With the addition of a clamp (T-Clamp) they can also be attached to virtually any vertical sided tank with a maximum wall thickness of 35mm for rectangular tanks, 30mm for circular tanks (300mm diameter), and a capacity of up to 50 litres. Minimum and maximum temperatures achievable are dependent on the tank insulation and minimum operating temperature depends on the accessory cooling device.
