Chromalox® announces a new line of WeatherTRACE heat trace control panels with flexible power distribution, ground fault protection, circuit alarms, line sensing, and ambient sensing controls.

The WeatherTRACE Sentinel Monitoring option offers alarms that indicate a ground fault or overload condition and identifies which circuit is at fault via a display on the front enunciator panel. This new capability reduces troubleshooting time and provides better indication of potential problems on the line. Sentinel Monitoring also offers a re-ring feature. Re-ring allows the WeatherTRACE to communicate additional alarm conditions in the system by momentarily clearing and resetting the alarm output contact. The customers' monitoring devices, such as a PLC or DCS, can interpret this condition as an additional alarm occurring.

The WeatherTRACE system incorporates an enclosure, circuit breakers, panel boards, monitoring, and GFI breakers to reduce onsite assembly, labor, and wiring time by consolidating multiple functions in one box. These panels meet UL and cUL approvals, always include detailed documentation, comply with NEC ground fault requirements, and are produced in an ISO9001:2000 manufacturing facility. The panels are NEMA 4, single-door, wall-mount enclosures for indoor and outdoor applications. Standard models are available in 12, 18, 20, 30 and 42 position panel boards with 100 and 225 amp bus ratings in single and three-phase configurations. Branch circuits are available in 20, 25, 30 and 40 amp single-pole and two-pole configurations with 30mA ground-fault equipment protection.

Stainless steel enclosures and built-in heaters are available as options for harsh environments. Type Z purge pressurization systems are also available for Class 1 Division 2 applications. Freeze Protection Ambient Sensing Series – FPAS The FPAS series controls groups of heat trace circuits with an external controller/thermostat. This system may be operated in two modes; automatically with the external controller, or in manual override via the Hand/Off/Auto selector switch.

Freeze Protection Line Sensing Series – FPLS The FPLS series controls heat trace lines with individual line sensing controls. Multiple sensors can be used to control individual circuits based on application and amperage.

Freeze Protection Ambient Sensing Monitor Series – FPASM The FPASM series controls groups of heat trace circuits with an external controller/thermostat. This system continually monitors the supply voltage to each heat trace circuit. Loss of voltage or a ground fault condition will trigger an automatic alarm condition.

Freeze Protection Line Sensing Monitor Series - FPLSM The FPLSM series controls heat trace lines with individual line sensing controls. Multiple sensors can be used to control individual circuits. An annunciator panel will identify the faulted zone and ring the alarm.

ProSonix DIRECT STEAM INJECTION ... HOW IT WORKS...

The PSX Direct Steam Injection heater uses a unique method of steam injection,
via Internal Steam Modulation, which offers a precise method of steam control
through a variable area, choked flow, steam injector.

Steam is accelerated though the steam injector into the steam condensing
chamber, where it is thoroughly mixed with the liquid to achieve rapid energy
transfer.

The steam injector controls the mass flow of steam so that is can precisely meter
the amount that is required for heating control.

PITTSBURGH — December 8, 2004 — Chromalox®, the world's largest manufacturer of industrial heat and control products, introduces the OEM Custom Control Platform (model CCP). It allows an OEM customer to quickly configure a custom temperature controller (up to 4 loops) complete with timers to meet specific application needs. The idea behind this platform is to simplify the development of custom controls, thereby reducing excessive lead times. This results in reduced costs and faster response to market for OEM customers.

The platform uses a set of pre-designed modules for input, output and control. The idea behind the platform is to use these modules to minimize the time to develop a custom control product. For prototypes, the modules are available as plug-in boards that can be mixed and matched for the application. When the functional design is approved, these modules can be quickly repackaged into a single board solution at a competitive price. All the modules are designed and technically supported by the Chromalox Engineering Department.

The basic operational capabilities of the Chromalox OEM Custom Controller/Timer include support for a variety of temperature sensor types and temperature control over one or two channels, Hi/Low temperature alarming, basic timer functions, and either one or two numeric displays capable of showing time in hours and minutes.

PITTSBURGH — May 25, 2004 — Chromalox®, the world's largest manufacturer of industrial heat and control products, is proud to announce that it has successfully obtained UL Listing for heating cables specific to Fire Protection System Piping. Recent changes in many city fire codes have required that heating cables used for freeze protection of fire protection system piping carry a special UL Listing specific to Fire Protection System Piping. Chromalox has obtained this UL Listing for the following models of heat trace cables: SRL-C, SRL-CR, SRL-CT, SRM/E-C, SRM/E-CT, SRF-C, and SRF-CR.

Chromalox self-regulating heating cables provide safe, reliable heat tracing for freeze protection of pipes, valves, tanks and similar applications. They are energy efficient and easy to install. Field splices can be performed quickly and easily with no wasted cold sections. In addition, the heating cable can be single overlapped without burnout. These cables are ideal for heating metal and plastic pipes typically used in commercial construction, institutional buildings, and industrial freeze protection applications, as well as for freeze protection of Fire Protection System Piping.

Chromalox self-regulating heat trace cables utilize a special semiconductive polymer core matrix bonded to the conductors, which minimizes the risk of an over-temperature condition. This also increases the cables' power efficiency because the core's electrical resistance varies inversely with temperature, consuming less power when less heat is required.
