Self-Regulating Heat Trace Cable

Self-regulating heat trace cable for ordinary and hazardous environments prevents pipe freezing
and maintains process temperatures. Constructed of a semiconductive polymer extruded
between parallel buss wires, the self-regulating cable adjusts its output to independently respond
to temperatures along its length. This heat trace cable can be single-layer overlapped. It is
flexible and can be cut to length in the field. Self-regulating cable can be used in Division 1 and
Division 2 hazardous areas.

. Circuit lengths: Up to 750 ft (280 m)
. Process maintenance temperature: Up to 302°F (150°C) Power ratings: 3, 5, 8, 10, 15, and 20
W/ft (10, 16, 26, 32, 48, and 65 W/m)
. Voltages: 120 and 208 to 277 V

Constant-Wattage Heat Trace Cable

Constant-wattage heat trace cable provides process temperature maintenance and freeze
protection. Its rugged construction can tolerate exposure temperatures to 392°F (200°C).
Fluoropolymer jackets are available for corrosive environments. Constant-wattage cable is
flexible, can be cut to length in the field, and can be used in Division 2 hazardous areas.

. Circuit lengths: Up to 780 ft (238 m) Process maintenance temperature: Up to 350°F (175°C)
. Power ratings: 4, 8, and 12 W/ft (13, 26, and 39 W/m)
. Voltages: 120, 208 to 277, and 480 V

Mineral-Insulated Heat Trace Cable

Mineral-insulated heat trace cable is suitable for the most demanding heat trace applications. Its
INCOLOY* sheath resists damage, is fire- resistant, and provides a reliable electrical ground.
Chromalox mineral-insulated cable can be used in Division 1 and Division 2 hazardous areas.
Circuit lengths: Up to 1,000 ft (305 m)

. Process maintenance temperature: Up to 1,100°F (593°C)
. Power ratings: 5 to 50 Wit (16 to 162 W/m) Voltages: 120 to 600 V

Commercial Freeze Protection Heat Trace Cable

Chromalox commercial freeze protection heat trace cable is ideal for keeping metal and plastic
pipes warm in commercial construction, institutional buildings, and some industrial freeze
protection applications. It is constructed of a self-regulating polymer core that varies its output
along its entire length, saving energy and eliminating hot spots along the pipe. Parallel
construction makes it easier to install than zone or series types of cable since it can be cut to
length at ary point on the pipe. It can be single-overlapped without overheating the cable.

. Maximum circuit length: 660 ft (200 m)
. Power ratings: 3, 5, and 8 W/ft (10, 16, and 26 W/m)
. Voltages: 120 and 208 to 277 V

Hazardous-Area Heat Trace Cable

Chromalox HSRL and HSRM self-regulating heat trace cable provide safe, reliable heat tracing
for freeze protection of pipes, valves, tanks, and similar applications. Constructed of industrial
grade 16 AWG buss wire with a tinned copper braid and fluoropolymer overjacket
ensures operating integrity in Division 1 hazardous environments.

. Maximum maintenance temperature rating: 150°F (65°C) and 302°F (150°C)
. Maximum exposure temperature: 185°F (85°C) and 420°F (215°C)

Series Resistance Long-Line Heat Trace Cable

Chromalox SLL heat trace cable provides safe, reliable process temperature maintenance and
freeze protection of pipes, valves, tanks, and similar applications with circuit lengths up to 7,500
ft (2,286 m). Constructed of industrial-grade 16, 14, 12, or 10 AWG buss wire with metal braid
and fluoropolymer overjacketing, SLL heat trace cable ensures operating integrity in most
hostile industrial environments. The 450°F (232°C) maximum exposure temperature rating
allows steam cleaning of process equipment with up to 300 psig steam.

. Maximum circuit lengths: Up to 7,500 ft (2,286 m)
. Power ratings: Up to 12 W/ft (39 W/m)
. Voltages: 120 to 600 V

Hot Water Maintenance Heat Trace Cable

Hot water temperature maintenance systems are designed to provide commercial buildings with
immediate hot water at the tap without the use of a recirculation system, thus saving on
unnecessary water waste. Systems are designed for maintaining desired nominal maintenance
temperatures various temperatures used in showers, baths, kitchen, and laundry facilities. HWM
cables replace heat lost through the thermal insulation on hot water supply piping to maintain
the water at desired nominal temperatures without the need for costly insulated recirculation
lines, pumps, and balancing valves. Chromalox offers a myriad of control solutions for these
applications from pipe-mounted single-point systems to multi-point distributed systems.

. Circuit lengths: Up to 800 ft (244 m)
. Power ratings: 5 and 10 W/ft (16 and 32 W/m)
. Voltages: 120 and 208 to 277 V
