GS Series Improvement - Tank Insulation Material
|
TB: 22-09
Date: December 16th, 2022
Product Lines Affected: GS Series
|
Condair’s continuous process of reporting and reviewing of product feedback is integral to our corporate value of being a reliable manufacturer. As part of this process, we have just released an improvement regarding GS Series gas-fired humidifier tank insulation material. Please review the information below.
|
GS tank insulation material degradation, and separation from the tank surface, was reported at three European sites. The insulation (shown in Figure 1 below) is not meant to be a consumable part and is designed to withstand regular operating conditions of the equipment throughout its entire life cycle. Tank insulation is located on the entire surface of the boiling tank as well as the tank clean-out door(s).

|
An improvement to the insulation material has been introduced to meet our customer’s and Condair’s own quality expectation. The existing foam insulation has been replaced with a new UL approved elastomeric insulation material that has improved material properties, specifically in terms of heat resistance.
|
The product improvement has taken effect in production on Dec 9, 2022, and affects the tank insulation installed on all GS Series Indoor and Outdoor (OC) units.
|
In the interim, the new insulation material will be provided in a grey colour as shown in figure 2 below. It is intended that the new material will return to the original black coloring later in 2023.

There have been no complaints of issues with products in the field in North America, and no product recall has been issued. The main goal of the material change is for continuous product improvement. If you determine that you have issue with tank insulation degradation or separation from the tank surface, please contact na.warranty@condair.com.
