Whenever workers are exposed to chemicals or contaminants on the job, safety showers must deliver water that has the right drenching temperature. ANSI Z358.1 (2014) recommends safety shower and eyewash drench liquid between 60° F and 100°F (inclusive). Water tanks used to feed safety showers and eyewashes that sit in hot summer sun may contain water that is too warm to be safely used for emergency showers and eyewashes.
Alpine Technical Services (ATS) has a solution for this. They supply Water Chillers for tank-fed safety showers and eyewashes which are operated in air temperature or where solar exposure is high enough to raise the temperature of the water in the tank to over 100° F. These Water Chillers , meet all regulations for Class 1 Division 1 and 2 areas, ATEX Zones 1 and 2 Flameproof Areas and Non-Flameproof Areas. They are ideal to increase the usefulness of tank-fed safety showers/eyewashes in sites that have no water supply, interrupted water supply or low water pressure. These Water Chillers guarantee compliant water temperatures, when properly installed and used as designed.
This type of Water Chiller utilizes a method of cooling water that has been found to be the most effective way to quickly reduce water temperature. This is essential for ensuring that the shower remains in use and that production on site is not hampered due to the shower being full of hot water and therefore unusable. When fitted to a 1500-liter tank shower, this Water Chiller guarantees that water can be flushed for 15 minutes from both the shower and eyewash simultaneously at no higher than 100° F, as recommended by the ANSI Z358.1 ( 2014) International Standard. The Water Chiller does not reduce the flow rate of the water.
These Water Chillers are ideal for any environment with air temperatures from 41° F to >120° F. Alpine Technical Services, the exclusive distributor for Showers and Eyebaths Services, provides both specs and pricing for this Water Chiller on their website, www.AlpineTech.us.
Effective Water Chillers are highly recommended in areas of high ambient temperature or where solar heat gain can cause water in tank-fed safety shower/eyewash units to reach temperatures about 100° F.
