Ice Machines

Ice machines are devices used to freeze water to make ice. Under certain conditions, the ice machines may support the growth of microbial pathogens, such as Legionella. Typically, this happens when small numbers of microorganisms in the potable water that feeds the ice machine grow inside the ice machine and contaminate the ice. Frequently, ice samples test positive for Legionella even when all other samples from the same potable water system are “non-detect”. Legionella bacteria from ice machines has been linked to outbreaks of Legionnaires’ disease.

Services

We collect samples from ice machines as part of our standard protocol for collecting samples from potable water systems for Legionella testing, consistent with New York State Department of Health guidance.
We offer a filtration-as-a-service program for ice machines. For an annual subscription fee, we install and maintain filters on ice machines. Typical scheduled filter replacement is every 6 months.
- To block bacteria, we use in-line or terminal point-of-use (POU) filters that are FDA cleared (510-K, Class II) and certified to ASTM Standard F838, Standard Test Method for Determining Bacterial Retention of Membrane Filters Utilized for Liquid Filtration.
- To block bacteria, viruses and endotoxins, we use in-line filters that are FDA cleared (510-K, Class II) and certified to AAMI TIR34: 2014 Water for the Reprocessing of Medical Devices.
