DirectConnect Process Heaters

Chromalox® DirectConnect™ process heaters utilize medium-voltage technology to
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 7,200 V.
As with traditional low-voltage systems, DirectConnect immersion and circulation heaters
can be adapted to suit virtually any liquid or gas application. 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.

DirectConnect Boilers

DirectConnect™ boilers merge the benefits of electric metal-sheathed-element steam
boilers 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. They are marked by long-lasting,
tough, and reliable metal-sheathed heating elements that are much more resilient with
process variation, varying water quality, and power fluctuations. Combining those
advantages with an electric boiler's variability, 99% efficiency (even at high turn-downs),
zero emissions, and point-of-use capability, a DirectConnect medium-voltage boiler
from Chromalox is a fantastic steam solution for every industry.

DirectConnect Heat Transfer Systems

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

DirectConnect Control Panels

Chromalox® DirectConnect™ control systems allow for a traditional contactor on/off
control scheme for medium-voltage process heaters, but is also able to provide full, 100
percent SCR power control at true medium voltage rated for continual operation. In
addition, a hybrid approach is available that enables contactor control for the base
load with an SCR trim option. This enables tight temperature control while managing
costs. Finally, and most important, is our patent-pending auto dry-out feature that enables
the DirectConnect process heating system to dry out the elements in place.
