  • High and low speed agitation
  • Standard sizes 5-1000 gal.
  • Electrically heated valve
  • Teflon coating available
  • Multiple circuit, blanket type heating
  • Voltages, phases, frequencies to suit
  • Custom built tanks to your specifications


For melting or heating pitch, asphalt, paraffin, waxes, plastics, oil, chemicals, deionized water, and a wide variety of other compounds.

Heating Element

The famous Sta-Warm “Even Heat” multiple circuit, blanket type element is uniformly applied to the entire bottom area and up the sidewalls to approximately 75% of the wall height. Even heat is distributed at a low watt density (approximately 5 watts per square inch maximum) eliminating the danger of “hot” spots.


Available voltages are 120, 208, 240, 480 or 550, single or three phase, 50 or 60 cycle. Other voltages or frequencies to order.


Inner tanks and housings are made of electrically welded mild steel. On special order, the inner tank can be fabricated of stainless steel. A split cover is supplied with lift handles. Glass blanket or expanded perlite is used as thermal insulation to reduce heat loss.

Solid state relays, contactors, control transformers, etc., when required, are mounted in a gasketed enclosure.


Electronic controls closely control the wall temperature. Each tank and control is operated a minimum of 12 hours continuously during calibration test, insuring the purchaser, of highest quality and trouble-free operation. Standard temperature range is 60 - 550 F. Digital temperature controls can be custom calibrated to meet your specific application needs.


The standard outlet supplied is an electrically heated and thermostatically controlled wheel type gate valve. It is externally mounted for accessibility. All iron or stainless steel valves are available, if required, as well as quick opening gate valves or needle dispensing valves. Valves have internal thermostats that are factory set to your specific application needs.
