DirectConnect Heat Transfer Systems

Medium Voltage Heat Transfer Systems 
Chromalox DirectConnect heat transfer systems utilizing medium voltage technology drastically reduce installation, operation, and maintenance costs for large heating demands. Medium voltage systems are engineered to provide precise process temperature control and are designed to operate for many years in service at voltages up to 7200 V. As with traditional low voltage systems, DirectConnect heat transfer systems are custom designed specifically to operate with organic and synthetic heat transfer oils, water, and water/glycol mixtures.

Common applications include:

• Jacketed tank heating of mixers, kettles, and storage tanks
• Roll heating of embossers, coaters, laminators, and calendars 
• Press heating of platens, belt, and laminating presses as well as compression molding|
• Reactor temperature control
• Process heat exchangers

Chromalox Technology
Over a century of product development and application experience are delivered in each product we manufacture. Chromalox in-house engineering and fabrication capability allows for an endless possibility of design. DirectConnect medium voltage heating technology is the culmination of our history. Our design innovations, testing, and independent certifications ensure unmatched quality of design with every unit. Electric heating provides the best option for heat transfer systems because of its overall efficiency, zero emissions, precise temperature control, and ability to supply exactly what is demanded by the process. Now, these advantages can be leveraged into much larger indirect process heating demands due to the DirectConnect medium voltage technology.
