Medium Voltage Process Heaters
Chromalox DirectConnect Process Heaters utilizing medium voltage technology drastically reduce installation, operation, and maintenance costs for large process 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 immersion and circulation heaters can be adapted to suit virtually any liquid or gas application.
Applications
Common applications include crude oil, natural gas, steam, heat transfer oil, hydraulic fluid, acidic solutions, potable and clean water, glycol solutions, hydrocarbons, industrial gases, hydrogen, oxygen, and superheated air. However, Chromalox has heated thousands and thousands of unique mixtures, solutions, and gas compositions over the years. Nobody has more experience.
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 process heating 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 process heating demands due to the DirectConnect medium voltage technology.
