Chapter 3: Installation

3-1 Positioning Your Dryer

The dehumidifying dryer system was designed to be wheeled into place. The entire assembly is mounted on a rugged, compact frame and is equipped with sturdy, 4” (10 cm) heavy-duty casters, two locking and two swivel.

Caution! Use caution and observe safety rules when placing your dryer!

3-2 Making Electrical Connections

;Fulfill all national, state, and local safety and electrical code requirements.

;Connections should be made by a qualified electrician.

;Make sure all electrical connections are tight.

;Connect main power to the dryer at the disconnect or terminals in the upper right corner of the control enclosure.

;Install a fused disconnect with a lockout feature in the power main leading to the dryer.

;The power drop must include a ground wire.

WARNING! Proper grounding of the main power line is critical!

3-3 Connecting Compressed Air

Connect compressed air to the dryer before operation.

Caution! Excessive air pressure damages the neoprene components of the air distribution valve.

Connect the air supply, using a ¼” NPT fitting, to a clean, dry, lightly lubricated source of 80 psi (551 kPa/5.51 bars) compressed air. A pressure gauge and regulator are recommended components of your plant air supply.

The compressed air indicator switch prevents the dryer from starting without an 80 psi (551 kPa/5.51 bars) air supply. If the air supply drops to below 60 psi (413 kPa/ 4.13bars) during operation, the dryer shuts down until at least 80 psi (551 kPa/5.51 bars) is restored.

3-4 Checking for Proper Blower Rotation

Three-Phase Models

The blower rotates properly when air flows from the delivery outlet and a vacuum is felt on the blower inlet.

Caution! In three-phase models, incorrect phasing of power leads can cause backward rotation of blower motors and CONTAMINATION OF THE DESICCANT! Always check blower rotation before putting material in the drying hopper!

If the three-phase blower rotates improperly, reverse any two wires at the fused disconnect outside the dryer or at the disconnect/terminal in the control enclosure. This assures that the blower rotates in the proper direction.

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.
