Duraline has a new range of modular distribution systems for electrical resistance preheat and heat treating welding applications.

Duraline has a new range of modular distribution systems for electrical resistance preheat and heat treating welding applications.

These economical and efficient systems offer the flexibility of a range of solutions, which includes: US Navy three- and four-wire systems with percentage timer; commercial percentage systems (mini-systems for preheat); thermostatically controlled Factory Mutual (FM) systems; and commercial system "A" (CBI) and commercial system "B" (JBB) thermostatically controlled Factory Mutual (FM) systems.

The US Navy three- and four-wire system configurations are not variable from the Bureau of Ships standard.

All components in these systems, including the control unit, are watertight for maximum safety, with waterproof-shielded connections.

Distribution blocks are neoprene rubber with mating plugs moulded to 600V heavy-duty cables.

The Duraline Mini-System is a line-voltage resistance heating system ideally suited for applications like preheating plates, spheres, vessels and other weldments having a fairly regular shape or a radius greater than 300mm.

It is designed so that all cable sizes take maximum advantage of their current carrying capabilities.

The thermostatically controlled FM systems, also known as the Duraline Smart Heaters, are the first electrical resistance heaters with independent thermostatic control.

Completely FM-approved, these systems reduce energy costs (by more than 30%) and man-hours by automatically monitoring and controlling the temperature at each weldment.

Input cables may be furnished up to 30m long on the six-outlet distribution block, and up to 15m long on the four-outlet main panel.

Duraline's latest addition to these systems is an optional panel mount receptacle, model 30FR4X, which provides additional flexibility and convenience.

Both the CBI and JBB type commercial systems allow the use of 1.8m thermostatically controlled heaters by incorporating a primary spider in place of the 3B20-6SR FM distribution block.

Accordingly, the system may be configured for most heaters using either the primary spider or the six-outlet distribution block.
