Fog Machine Chillers — An Ultimate Guide

Fog machine chillers are devices used to cool down the hot fog produced by fog machines, resulting in a denser and longer-lasting fog effect. These chillers are designed to enhance the performance of fog machines by cooling the fog before it is released into the environment.

By passing the fog through a chamber filled with ice or by using frozen water bottles, the temperature of the fog is lowered, causing it to stay closer to the ground and creating a thick, low-lying fog effect.

Fog machine chillers are widely used in various applications such as stage productions, haunted houses, special events, and live performances to create an atmospheric and visually appealing ambiance.

How Does Fog Machine Chillers Work

When fog is produced by a fog machine, it is initially hot and tends to rise upwards. To create a chilling effect and make the fog stay low to the ground, fog machine chillers are used. These chillers consist of a container filled with ice, into which the fog is pumped.

As the fog enters the container at the top, it encounters the cold ice and sinks down, cooling the fog in the process. This cold fog then emerges from the bottom of the container, staying close to the ground.

By utilizing the principle that cold air sinks, fog machine chillers effectively create a dense, low-lying fog effect that adds ambiance and atmosphere to various events and performances.

Tools Used:

  • Drill
  • Screwdriver
  • Scissors
  • Saw (hacksaw, jig saw, bandsaw, etc.)
  • Tape measure
  • Black marker
  • Hot glue gun

Step 1: The Container and Plumbing

Start by selecting a plastic storage bin or similar container with a lid. Drill a circular hole at the bottom of each end, matching the diameter of the PVC pipe you will use. Alternatively, you can carefully cut the hole with a razor blade. Create pilot holes roughly halfway up the container and secure screws and washers on each hole from the outside using silicone or glue for an airtight seal. Optionally, add a drain plug near the bottom for easy ice melt disposal.

Step 2: Assembling the Plumbing

Slide a piece of PVC pipe through one of the holes, attach a 90-degree adapter, and connect the second piece of pipe. Cut the pipe at a mark just below the container’s top, using a saw suitable for cutting plastic. Use small half-inch rings with slits as clamps to hold the pipes together. Dab hot glue to secure the connections, ensuring they stay airtight.

Step 3: Incorporating Chicken Wire

Cut a piece of chicken wire larger than the container’s top. Bend and shape it into a “bowl” as you push it into the container. Lay a second piece of chicken wire over the first, providing added strength and preventing ice from falling through the holes. Create a small hole for the PVC pipe. Hook the chicken wire onto the screws from step one, which allows for easy removal if needed.

Step 4: Finishing Touches

Apply foam or cloth around the container’s top edge using hot glue to improve the chiller’s airtightness. Spray paint the entire setup with black paint for a sleek appearance. Customize and decorate further to suit your event or Halloween haunt.
