The direct injection Scepter tank heater is uniquely designed so that steam can be directly injected into water tanks to heat water-compatible products.
The tank heater also has a powerful stirring action that keeps any particulates or solids suspended. The whole process of heating water in a Scepter tank heater is vibration free, quiet and fully efficient.
This unique stirring action of a Scepter tank heater also produces a uniform temperature in the tank’s entire water content, which in turn, allows accurate and precise thermostatic control.
The Scepter tank heater is made from pure stainless steel (type 316 ) and are available in pipe sizes ranging from one inch to ten inches, which are also mountable on a tank from any position – below, above or with a side-port configuration.
For the steam to pass through, these are also available with threaded pipe connections, with pipe sizes ranging from one inch to three inches.
When the Scepter tank heater is inserted into a particular tank, the exiting steam’s momentum draws the liquid into the module’s perimeter that surrounds the steam inlet.
The steam and water get divided as also mixed by all existing mixing elements in each hole of the module, exiting as a full set of co-rotating vortexes.
These again give rise to numerous impingement mixing zones at the mixing module’s exit to produce complete steam as also the product that needs heating. The additional advantage is that it’s all done in a quiet and low-vibration environment without any additional air supply. Impressive!
The average Scepter tank heater comes with RFSO flanged connections in all sizes and weighs 150 lb. Every unit has a special module through a pipe with a diameter of about 2/3 the size of Equalizer’s external diameter. There is no water hammer.
As compared to traditional steam spargers, known for their banging and violent vibrations, the Scepter tank heater is a welcome change as it eliminates the banging and vibrations completely. This has been successfully used in a tanks with a volume of 37,140 US gallons; temperature range of 43 deg. F to 122 deg. F; a steam source of 65 psi, saturated; heating time of two hours and a steam flow rate of 10,000 #/hr.
Another successful implementation has been done in a rectangular water tank to heat water in less than half an hour to enhance the production speed.
