Greenheck Innovation


Greenheck’s remote balancing dampers are ideal for applications where tight spaces make it difficult to access and manually adjust the damper and balance airflow. Instead of using a traditional mechanical cable which is prone to binding, Greenheck’s remote balancing dampers use a standard RJ11 cable that is run to a phone jack-style plug. Greenheck’s EZ Balance smart controller can then be plugged into the jack to regulate the damper’s blade position and balance the system.


The EZ Balance Remote System


Two models of Greenheck remote balancing dampers can be specified. Model RDB-10 is a single blade rectangular balancing damper with a 9-volt actuator kit. Model RBDR-50 is a round balancing damper with a factory mounted 9-volt actuator. Accessories including cable and mounting plates are also available.

Greenheck offers the most AMCA-licensed dampers in the industry and is the worldwide leader in manufacturing and distributing air movement and control equipment.

Find The Temperature With Cricket Chirps


Did you know? You can tell the temperature by counting the chirps of a cricket! Here’s the formula.

How To Tell The Temperature With Cricket Chirps

In Fahrenheit

To convert cricket chirps to degrees Fahrenheit, count the number of chirps in 14 seconds, then add 40 to get the temperature.

Example: 30 chirps + 40 = 70°F

In Celsius

To convert cricket chirps to degrees Celsius, count the number of chirps in 25 seconds, divide by 3, then add 4 to get the temperature.

Example: (48 chirps divided by 3) + 4 = 20°C

Why do crickets chirp?

Chirping is a cricket’s way of communicating. Male crickets use chirping to attract females, scare off other males, or warn of danger. Contrary to popular belief, crickets do not use their legs to chirp! In fact, crickets produce the iconic sound by rubbing the edges of their wings together.
