MOUNTING

WARNING: Hazard of Electric Shock. Disconnect all power before installing heater.

Note: These heaters are designed for wall or ceiling mounting only. Other modes of mounting voids factory warranty.

1.Height above floor

A.In areas where ceiling height is more than 12 feet, recom- mended mounting height is approximately 10 feet to under- side of heater.

B.For ceiling heights of 12 feet or less, maximum mounting height is determined by use of ceiling mounting brackets offered for these heaters. Minimum spacing to ceiling is 3” (see Figure 2).

C.In either case, minimum mounting height is 7 feet from floor to bottom of heater. (See Figures 1 and 2.)

2.Spacing to adjacent walls

A.Rear of case to back wall 4-7/8” minimum (see Figure 2).

B.Side of case to side wall 6” minimum (see Figure 2).

3.If two or more units are operated in the same enclosed space, their discharges should be directed to aid in development of mass air movement for uniform heat dispersal.

4.Controlling thermostats to individual heaters should be mounted at shoulder height on inside walls or columns.

UB-752D, UB-502D specifications

The Chromalox UB-502D and UB-752D are advanced electronic temperature control units designed for precise temperature management in various industrial applications. These units excel in providing reliable and efficient heating solutions, making them suitable for diverse environments such as manufacturing facilities, laboratories, and testing centers.

One of the standout features of the UB-502D and UB-752D is their dual-output capability, rendering them capable of controlling two separate heating zones independently. This is particularly advantageous in processes requiring different temperature settings, allowing for greater flexibility and efficiency in operations. Each unit is equipped with a digital display and user-friendly interface, facilitating easy navigation and real-time monitoring of temperature settings.

The UB-502D and UB-752D utilize advanced PID (Proportional-Integral-Derivative) control technology. This sophisticated control algorithm continuously adjusts the heating output, ensuring temperatures remain stable and within the desired range. This level of precision enhances process reliability and contributes to improved product quality, which is essential in industries where temperature control is critical.

Both models incorporate a wide temperature control range, making them suitable for various applications. The UB-502D can regulate temperatures up to 500°F, while the UB-752D extends this capability to 750°F, catering to high-temperature requirements. This versatility allows them to accommodate a range of heating applications, from material processing to equipment heating.

Another significant aspect is the robust construction of these units, designed to withstand harsh industrial conditions. The durable housing not only ensures longevity but also contributes to safety, safeguarding against potential hazards associated with overheating or equipment failures. Moreover, the units are designed with built-in safety features like over-temperature protection and alarms, providing an extra layer of security in operational settings.

The Chromalox UB-502D and UB-752D also offer options for remote monitoring and control, allowing operators to manage temperature settings from a distance. This connectivity is increasingly important in modern industrial environments where real-time data and remote access can enhance operational efficiency and responsiveness.

In conclusion, the Chromalox UB-502D and UB-752D are state-of-the-art electronic temperature control units that combine precision, flexibility, and safety. Their advanced technologies, robust design, and user-friendly interfaces make them indispensable tools for any industrial application requiring reliable temperature management. Whether for manufacturing processes or laboratory experiments, these units set a standard for performance and efficiency in temperature control solutions.
