Comfort Zone® is ideal for warming towels, blankets or robes with no plastic or metal components. It is used by EMTs to assist in raising the body temperature of patients who are in shock or hypothermic. It helps with elderly patients who may have difficulty maintaining body temperature. Veterinarians also find it useful to soothe and calm animals both before and after surgery. The advantages that Comfort Zone® has over traditional electric blankets is that it is not susceptible to the “hot spots” that wired heating blankets can develop nor does it present the electrical hazards that wired heating blankets do.

Comfort Zone® is approved by Underwriters Laboratories (UL) under the United States and Canadian standards for indoor appliances.

The warming plates are controlled by a thermostat that regulates the heat between 155°F and 185°F (68°C to 85°C). Once heated, the plates are hot to the touch. The unit should not be left where a child or incapacitated person can be in contact with the plates while the unit is on. In addition to the thermostatically controlled heat, controls in both plates will disable the unit if the thermostats should fail.

The moisture comes from articles being warmed and does not affect the operation of the unit nor does it present a safety hazard. With the unit off, wipe any accumulated moisture up with a dry cloth.

Comfort Zone® may be returned for any reason within 30 days of purchase and is warranted to be free of defects in workmanship or materials for one year. Details of both the return policy and warranty are here.

If the unit is cold, it may take up to 20 minutes to warm two blankets, towels, or robes. A unit that has just completed warming an item will heat the next item in about 10 minutes. These times can vary based on the cloth or material used and the outside environment.

The unit is well insulated and will retain heat for up to 30 minutes even after it is turned off.

The unit operates between 155°F and 185°F. Blankets, towels, and robes that are placed in the unit will range in temperature from 110°F and 155°F after the full warm-up period.

Any unadorned blanket, towel or robe that is made of cotton, polyester or a blend of the two fibers may be used in Comfort Zone®. Items that have buttons, zippers, or other plastic or metal components should never be used in Comfort Zone®.

The unit should be turned off and allowed to cool. The plates can be wiped down with a cloth dampened with water or alcohol. Allow to dry completely before returning to use.

It is not safe to warm any fluids, including serum or IV fluids, in Comfort Zone®, for human use. The unit should only be used to warm unadorned textile products.

The unit is designed to accommodate extended usage. However, it does consume power while on, so it should be turned off if it will not be used for several hours. This will also extend the life of the unit as it will reduce the number of times that the thermostat cycles on and off.

That is a pressure relief valve that is incorporated into the Hardigg Storm Case and assures that that there is no build-up of either negative or positive air pressure while the case is in use.
