Umax® Shell & Tube

The extreme hardness, high theoretical density, excellent strength properties, and absence of free silicon make Umax advanced ceramic inherently corrosion and erosion proof. It is the preferred material choice for processes involving mixed acids, bromine, hydrofluoric acid, free halogens, caustic, and other very aggressive reducing or oxidizing environments.

• Umax® advanced ceramic is inherently corrosion and erosion-proof. All Umax® tubing carries with it a two year unconditional guarantee against corrosion and erosion.
• If required, the tubes can easily be replaced in the field using common tools.
• Extremely resistant to fouling.
• 100% resistant to thermal shock and erosion damage throughout its operating range.
• Designed and tested per ASME SEC VIII Div 1, TEMA, ANSI, ASTM, and stringent in-house standards.

Cubic Block

Impervite® is a composite material consisting of a graphite substrate impregnated using a proprietary phenolic impregnation process. Impervite is ideally suited for processing mixed acids, sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, waste acids, and chlorinated hydrocarbons. It has excellent machining, physical, and thermal properties.

CG Thermal Impervite® cubic block heat exchangers offer many of the same features as our heavy duty cylindrical block heat exchangers and are fabricated using the same high quality impervious graphite, but typically at a lower investment cost.

• Maximum heat transfer area in minimum envelope size
• High thermal efficiency, even with low temperature approach and temperature cross
• Single piece, monolithic Impervite® cubic element
• All the metal components can be supplied with a full ASME SEC VIII Div 1 code stamp
• Design allows easy access to both the service and process side of the unit, making them easy to clean and maintain

Multi-Blox™ Cylindrical

Impervite® is a composite material consisting of a graphite substrate impregnated using a proprietary phenolic impregnation process. Impervite is ideally suited for processing mixed acids, sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, waste acids, and chlorinated hydrocarbons. It has excellent machining, physical, and thermal properties.

• Our cylindrical units utilize some of the longest monolithic blocks available, greatly reducing the number of required sealing gaskets.
• Maximum heat transfer area in minimum envelope size.
• Designed and tested per ASME SEC VIII Div 1, TEMA, ANSI, ASTM, and stringent in-house standards.
• Design allows complete access to both process and service side of the unit.
• Design pressures up to 150 psig (10.34 barg) at 340 Deg F (171 Deg C).
• Excellent resistance to thermal shock, water/steam hammer and other mechanical abuses.

Impervite® is a composite material consisting of a graphite substrate impregnated using a proprietary phenolic impregnation process. Impervite is ideally suited for processing mixed acids, sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, waste acids, and chlorinated hydrocarbons. It has excellent machining, physical, and thermal properties.

• Designed and tested per ASME SEC VIII Div 1, TEMA, ANSI, ASTM, and stringent in-house standards.
• Large cross-sectional process flow areas for low pressure drop and/or high fouling applications.
• Up to 100 psig (6.89 barg) and 340 Deg F (171 Deg C) operating conditions.
• Exceptional fatigue resistance.
• High thermal efficiency.
• Tube diameter options include 7/8” (22 mm) and 1.50” (38 mm) inside diameter.
• Heat transfer areas range from 8 ft² (.74 M²) to 15,500 ft² (1,448 M²).
