6-6 Replacing the Process Heater

Our dehumidifying dryers use Calrod-type heater elements mounted in a heater tube located in the top rear of the cabinet. The wattage of the heater varies with model, voltage, temperature range, etc., but the replacement procedure is the same.

If the process heater is mounted to the hopper, contact the manufacturer for the appropriate replacement procedure.

WARNING!

Disconnect and lock out power before you replace heater elements!

Use the following procedure to replace the process heater:

1.Remove the bolts securing the process heater access cover.

2.Sketch the heater wiring configuration so you can properly re-wire the heater.

3.Remove the wires to the heater plate assembly being removed or replaced.

4.Remove the bolts securing the heater plate assembly, and slide out the assembly.

5.Remove the heater from the mounting plate by removing the large brass nuts and washers.

6.Re-install the heater and heater plate assemblies in reverse order. Install new heater gaskets and securely tighten all fasteners.

Caution! Heater loops should not touch each other. “Hot Spots” lead to premature heater failure!

7.Reinstall the wires based on the sketch you made earlier.

8.Secure the heater access cover.

SDA 150-380, 90-225 CFM specifications

The Sterling 90-225 CFM and SDA 150-380 series represent cutting-edge advancements in air compressor technology, designed for a wide range of industrial applications. Known for their reliability, efficiency, and superior performance, these units are essential tools for professionals seeking high-quality compressed air solutions.

One of the standout features of the Sterling 90-225 CFM series is its impressive flow rate. With a capacity range of 90 to 225 cubic feet per minute, these compressors offer ample airflow to power pneumatic tools and equipment while maintaining optimal pressure levels. The durability of the components used in the construction of this series ensures that it can withstand the rigors of heavy-duty operations while minimizing downtime.

The SDA 150-380 series further enhances this approach with its higher capacity range, accommodating between 150 to 380 CFM. This variant is particularly suitable for larger facilities and demanding applications where sustained airflow is essential. Both series are designed to adapt to various pressure requirements, making them versatile solutions for different industries, including manufacturing, construction, and automotive sectors.

A key technology featured in both series is the use of energy-efficient motors, which significantly reduce operational costs. These motors are designed to deliver high torque at low speeds, ensuring smooth operation and less wear on the compressor. Furthermore, the incorporation of advanced control systems allows for real-time monitoring and adjustments to optimize performance, ensuring that the compressors operate within desired parameters continuously.

Noise reduction is another critical aspect of both the Sterling and SDA series. Innovatively engineered with sound-attenuating materials, these compressors operate at lower decibel levels, providing a more pleasant working environment. This focus on user comfort doesn’t sacrifice performance, as the units are built to achieve maximum efficiency even at reduced noise levels.

The ease of maintenance is another important characteristic. Both models are equipped with user-friendly access points for essential components, simplifying routine checks and servicing procedures. This results in less downtime and improved reliability across the operational lifespan of the compressors.

In conclusion, the Sterling 90-225 CFM and SDA 150-380 series compressors set a benchmark in the industry, offering a blend of performance, efficiency, and user-friendly features that cater to various industrial needs. Their robust construction, advanced technology, and focus on user comfort make them ideal choices for businesses seeking to enhance productivity and reduce operational costs.
