Rectangular tanks may be used as compound melters or as dipping tanks for wax, plastic tooling coating or potting material. The most common uses include cleaning, degreasing, or dip coating of machined parts and tools with wax, ethyl-cellulose compound or other rust preventing material.
Custom Built
Sta-Warm rectangular compound melting tanks are adaptable to countless industrial melting and dipping applications because each tank is custom built to basic size and shape requirements established by the user.
Sta-Warm basic construction and heating application is sufficiently flexible to accommodate itself to extra-ordinary shapes and sizes as required. For instance, a 1,000 gal. tank of “T” shape with sloping bottom has been built and is being used successfully for dipping the liners of household refrigerators. Long, lean proportions or short, square, deep shapes can be made to suit the general design of particular parts to be dipped. Temperature ranges to suit heat requirements of various compounds can be engineered as required, as can various types of outlets, valves, dipping baskets, plungers for displacing materials, lids, partitions, etc.
Applications
Sta-Warm rectangular tanks may be used as compound melters or as dipping tanks. Probably the most common uses include cleaning, degreasing, or dip coating of machined parts and tools with wax, ethyl-cellulose compound or other rust preventing material.
Designed with 36 heating circuits cemented to within 3” of top of sidewalls. Heat density; 3 watts per sq. in. of tank wall and bottom surface area. A 1” wheel type gate valve for draining contents was located inside of the heating chamber to avoid freezing in the valve. Built with hinged, insulated lid and with perforated partition for melting cold material separately from dipping chamber. A disconnect switch was included.
Basic Construction
To produce a ruggedly constructed tank that will withstand many years of steady use, a welded steel inner tank plus sheet steel housing and internally welded angle iron legs of desirable length are usually supplied. The most common type of drain outlet is a 1” heated gate valve. Entire sidewall and bottom area of each tank is heavily protected with heat insulating material.
Heating Arrangement
The secret of Sta-Warm’s uniform, low-wattage heat is found in the design of multiple heating circuits which blanket sidewall and bottom areas of the inner tank. Many feet of specially wound resistance wire, arranged in as many circuits as necessary to provide heating zones, are cemented to the tank. High wattage spotty heat is eliminated and so is the tendency to carbonize or burn the tank contents.
The broad distribution of Sta-Warm heat results in low average heat densities of approximately 3 to 6 watts per square inch, increasing the operating efficiency of the unit.
Heat Controls
Various type of heat controls are supplied according to the requirements of a particular installation. Standard spread normally 50°F - 550°F. Special timers, temperature limit, programming and zone controls are available. Along with digital controls.
Voltages
Units may be wired to operate on any practical voltage below 550 volts.
Special Equipment and Accessories
The design features of Sta-Warm Rectangular Tanks can be adapted in may ways to meet operating requirement.
One popular accessory often supplied is a dipping basket of expanded metal. Tanks may have a vertical divider screen, or be built in two sections, so recently added cold material will melt without interfering with the dipping area.
Various styles of electrically heated (or unheated) draw off and drain valves can be installed. Or, electrically heated rigid pipe can be supplied for conveying melted material from one tank to another
or to point of use.
Hinged lids or loose covers, with or without insulation, are available.
Tanks may be built on legs of various lengths, or without legs for bench use. Legs may be equipped with large roller casters to make the tank semi-portable.
Sta-Warm builds a special line of rectangular tanks that are particularly adapted to melting ethyl-cellulose and thermo-plastic compounds.
Quotations and Prices
Sta-Warm rectangular tanks are custom built and prices are based on capacity and voltage of each particular tank. Electrically heated industrial ovens for drying or baking can be designed for your
particular requirement.
