Aries Solvent Heater

Aries Solvent Heater


The Aries Solvent Heater safely heats thermally-sensitive fluids such as Isopropyl Alcohol (IPA) and EKC photoresist remover. This heater is ideal for both single-pass and recirculating applications where process temperature, fluid cleanliness and safety are all critical. Furthermore, Aries is an ETL-Listed product, and is UL-823 certified as explosion-proof, dust-ignition proof, and dust-tight, suitable for use in hazardous locations where flammable gases and liquids are present. Several optional controller packages are also available for the Aries on customer request.


The solvent heater incorporates design features for effective and safe heating to UL standards. For instance, the insulated housing is explosion-proof, dust ignition-proof, and dust tight.  High-pot material epoxy embeds the lead wires, and the heater core comes in a sealed 304 stainless steel enclosure. Furthermore, the ground fault circuit integrator serves as a quick safety switch to prevent too much power into the heater. Finally, the independent fluid path permits the heater to heat flammable fluids.


This heater features a 316L stainless steel coiled tube for wetted surfaces. A durable stainless steel fluid path that is independent of the heater element allows the Aries to effectively heat flammable fluids. Hermetically-sealed electrical and control connections, with thermocouples for process and over-temperature, ensure safe operation.


The design of the heater includes a cooling flow path, removing residual heat when the process is complete. This ensures that when fluid is not needed, process flow temperature is reduced; protecting both the heater and the operator.


Heateflex can custom build Aries heaters to meet specific customer requirements. Various optional controller packages are also available upon request. Models range from 2.5 to 9.0 kW, dependent on various voltages. Operating temperature is 203º F (95º C), and operating pressure is 60 psi at 95º C.
