Liquid and Gas Heating Components for Medical Devices

Nearly all fluid heating instruments from CAS feature isolated flow-paths, a design feature with distinct cleanliness advantages. Heated fluids are sequestered in a high-purity flow-tube (medical-grade PFA / PTFE or electropolished stainless steel), never contacting the heating element or any other heater constituent.

CAS can be relied upon to design and manufacture high-purity heated components for the most critical applications, including dialysis. Virtually all our designs include isolated flow-paths, meaning the liquid or gas being heated never contacts the heating element or any other component within the heater.

Medical Device Heaters For Immunoassay Analyzers From Cast Aluminum Solutions

Immunoassay and blood gas analyzers represent appropriate matches for the small medical device heaters CAS manufactures. Different applications require distinct material choices and heater formats. CAS Engineers work directly with customers to ensure integration of the most appropriate materials, components, and manufacturing approaches.

PFA Tube Medical Device Heater Cast Aluminum Solutions

Our unique PUR-X design is available in several sizes for deployment in an array of gas or liquid warming applications. The high-purity medical-grade PFA flow-tube is removable and replaceable. For in-cabinet applications, this no-enclosure option is a very compact option. Waterproof terminal enclosures are available for units mounted for exposure. Heater bodies may be Teflon or epoxy coated.

Medical Device Heater For Blood Cast Aluminum Solutions

This miniature in-line heater features a replaceable cartridge heater and helical coiled 1/8” OD seamless stainless steel electropolished flow-tube. Isolated in the SST tube, heated media has zero contact with the heating element: an important contamination prevention feature. The cast-in design also offers very efficient heat transfer, and built-in temperature sensors facilitate easy integration with most standard controls.

A variety of high-purity nonporous polymer tubes are available for integration with CAS heater designs. Chemistries include PFA, PTFE, TPE and ETFE, with outside diameters as small as 1/8” (3.175 mm) and temperature capabilities to 275°F (135°C). Components may be certified to FDA, USP, or EU purity standards.

For devices utilizing seamless stainless steel flow-tubes, materials can be certified to ASTM A270 or ASME BPE specifications. These electropolished wetted surfaces can achieve roughness averages as low as 7 μin Ra (.17780 μm). As a final cleaning process, IDs may be passivated to appropriate ASTM specifications.

Liquid Oxygen Vaporization Heater For Medical Gas Cast Aluminum Solutions

CAS offers high-purity oxygen and air heating solutions for liquid oxygen vaporization (oxygen concentrators), on-site gas generation, and point-of-use station outlets. Small nebulizer-mounted heaters can also be manufactured for specialty inhalers.

Group 1 011

For applications with relatively high flow volumes, our PUR-X 2000 and PUR-X 1000 inline heaters may be recommended (max. power to 7.9 kW and 4.5 kW respectively). Standard features include removable and replaceable 3/8” (9.5 mm) OD high-purity PFA flow-tubes, and easily-cleaned Teflon®-coated heater bodies.

Drug Manufacturing and Biopharmaceutical Processing Heaters

Our CAST-X Circulation Heaters offer the same high-purity “isolated flow-path” design featured in our medical device heaters, but with the increased flow and power ceilings required by high-throughput applications such as medicine manufacturing and blood additive processing.
