Dive Platform — Add-On Detail

A sturdy, low-profile platform designed to provide a clean, stable base for your soft-shell hyperbaric chamber. Ideal for home, clinic, or wellness-office use, this platform helps elevate the chamber off the floor while creating a more polished and professional setup. Built with durability and daily use in mind, it offers reliable support, improved presentation, and easier access around the chamber area.

Chamber Silencer, 2-Hole — Add-On Detail

This patented silencer (US Patent #9,664,202 B2) is designed to be used exclusively with Summit to Sea Shallow Dive, Dive, Grand Dive, Dive Vertical, and Grand Dive Pro chambers. An ideal solution for any hyperbaric application where a calm, quiet environment matters, it uses proven hyperbaric principles to absorb external noise generated by pumps — so the experience inside the chamber stays comfortably quiet. Small and compact, it is built with the same high-quality materials found in all Summit to Sea portable mild hyperbaric chambers.

Common uses include:

  • Silencing compressors
  • Reducing pump-related vibration

Chamber Cooler — Add-On Detail

This cooler, designed by Cool Hyperbarics, is unique to the hyperbaric cooling industry. It utilizes a heat exchange technology based on the zero-pressure differential principle, which prevents the reheating of cooled air as it enters the chamber. The present invention accomplishes this by arranging an air compressing unit, an air cooling unit, and an air discharging hose so that a flow of output warm air from the hyperbaric chamber can be recycled and converted into a flow of input cold air.
