Advanced HVAC Temperature Control

Components of a Zoned Damper System

From the standard furnace to the thermostats and dampers, each piece plays its part in creating a harmonious climate. It’s like a well-conducted orchestra, and we know every note.

Importance of Pressure Relief

Pressure relief isn’t just a safety valve; it’s the art of balance in your HVAC system. Here’s how we strike that balance:

  1. Over-sizing of Ductwork: Think of it as giving your system room to breathe, ensuring smooth airflow.
  2. Bypass Damper: This is your system’s safety net, redirecting air when needed and keeping everything in check.
  3. Controlled Pressure Relief (CPR) Method: The CPR method is like having a tailored suit for your HVAC. It’s designed to fit just right, eliminating the need for a bypass damper and keeping things efficient.

Maximizing Comfort and Minimizing Cost

By fine-tuning your system with our advanced temperature control solutions, we make sure you’re comfortable without breaking the bank. It’s not just about technology; it’s about smart, human-centered design. 

That’s our promise to you.

Dampers can be made of carbon steel, stainless steel, aluminum, fiberglass and more. The material selection depends on the application requirements, such as temperature, pressure, and corrosiveness of the environment.

Dampers come in various designs, including butterfly dampers, louver dampers, corrosive duty dampers, and rotary dampers. The design selection depends on the specific application and the required level of control.

The selection of dampers depends on various factors, including the temperature, pressure, and corrosiveness of the environment, the flow rate, and the type of media being handled. It’s essential to consider these factors when selecting the appropriate damper for a specific application.

When designing dampers, engineers must consider factors such as the operating conditions, the required level of control, the size and weight of the damper, and the potential for vibration or noise.

Pneumatic Controls and Sensors

Our pneumatic controls and sensors are the eyes and ears of your system, always alert and responsive.

Manual actuation involves manually operating the damper by turning a handle or lever. Manual actuation is simple and affordable but may be challenging for larger or hard-to-reach dampers.

Pneumatic actuation uses compressed air to operate the damper via a pneumatic actuator. Pneumatic actuation is relatively quick, precise, and suitable for many industrial applications. However, it requires an air supply and may be vulnerable to leaks.

Electric actuation uses an electric motor to operate the damper via an electric actuator. Electric actuation is precise, efficient, and ideal for automation and precise control. However, it can be costly and requires an electrical supply.

Hydraulic actuation uses hydraulic fluid to operate the damper via a hydraulic actuator. Hydraulic actuation provides high force and is ideal for large dampers or those requiring precise control. However, it can be costly, require maintenance, and may be prone to leaks.

Each damper actuation method has its strengths and weaknesses. Manual actuation is simple and affordable, pneumatic actuation is relatively quick and precise, electric actuation is efficient and ideal for automation, and hydraulic actuation provides high force and is ideal for large dampers. 

The choice of the appropriate actuation method depends on various factors, such as the level of control required, damper size, and available power sources. Speak with a qualified engineer to find out which is the best industrial damper for your application.


Organizations like OSHA, ASHRAE, and the National Fire Protection Association set industry standards and regulations for dampers. They provide guidelines for design, materials, testing, and installation, ensuring the safe and efficient operation of industrial processes.
Compliance with industry standards and regulations is vital for protecting personnel, equipment, and the environment. Non-compliance can result in accidents, injuries, environmental harm, and serious consequences for businesses and employees.
OSHA establishes guidelines for dampers in the workplace, covering design, installation, maintenance, and employee training. These rules emphasize safety and compliance with industry standards to reduce the risk of accidents.
