The Universal Solvent Heater from Cast Aluminum Solutions
(CAS) has been designed and tested to perform at the highest
levels when heating volatile, low-flashpoint solvents.

The USH features efficient low-watt-density heating elements
cast into an aluminum body that also contains two helical-coiled
stainless steel tubes; a small cooling tube for water (to reduce
solvent temps below flashpoint), and a larger solvent tube
(passivated & electro-polished). Solvents are sequestered in this
tube, never contacting the heating elements, which prevents
contamination and reduces the risk of explosion.

Three J-Type thermocouples sense solvent inlet, outlet and
heater core temperatures. A snap-action high limit switch pro
vides safe shutdown of the unit. The electrical enclosure is ex­plosion proof (NEMA 7). To protect it from corrosion, the body
is T

eflon® coated. This is the ultimate solvent heating device.
