DirectConnect Boilers

Medium Voltage Boilers

Chromalox DirectConnect boilers utilizing medium voltage technology drastically reduce installation, operation, and maintenance costs for large steam boiler applications. Medium voltage systems are engineered to provide precise steam control and are designed to operate for many years in service at voltages up to 7200 V. For the first time in history, the benefits of electric metal sheath element steam boilers are merged with the advantages of medium voltage operation to enable much larger boiler capacity.

Unlike large capacity electrode boilers, which have a tendency to be difficult to operate, maintain, and repair, Chromalox DirectConnect medium voltage boilers are as robust and reliable as their low voltage counterparts. You can count on long-lasting, tough, and reliable metal sheathed heating elements that are much more resilient with process variation, questionable water quality, and power fluctuations. Combined those advantages with an electric boiler's variability, efficiency (even at 10:1 turndown ratios), zero emissions, and point-of-use capability, a DirectConnect medium voltage boiler from Chromalox is a fantastic steam solution for every industry.

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 steam boilers because of all of the advantages mentioned above. Now, these advantages can be leveraged into much larger steam demands due to the DirectConnect medium voltage technology.
