By Luke Wonnell If you’re like me then you remember learning in High School chemistry or pre-req college courses that water has 3 states: solid, liquid and gas right? Water becomes solid ice below 32⁰F, exists as a liquid between 33⁰F and 212⁰F and starts to boil off to a gas at 212⁰F. While these […]
Modern HVAC design often employs a wide selection of metals which are used in system components and transmission lines. New construction specifications require protection for systems comprised of steel, copper, bronze, stainless steel, galvanized and even aluminum. In most cases, multiple metals are usually present in any given system. In addition, some component suppliers specify/demand […]
Cooling tower overflow is a subtle, yet costly problem which often goes unnoticed. The challenge is more pronounced during colder weather when heat rejection and evaporation requirements tend to be lower. The primary purpose of the cooling tower is to reduce water consumption. Overflow obviously defeats this purpose by robbing those savings. The problem can […]

Notification and Communication Strategies For the last part of our MPP series we will talk about the communications requirement of RCNY 8-03. This component requires a management program & plan to identify how results from cooling tower related activities will be received by different team members, and ultimately notification given to the department of health […]
Start-up and Shutdown Procedures For the next section of our MPP series we will talk about the Start-Up and Shutdown procedures that must be included in an MPP. As this is considered a very important element of the Maintenance Program & Plan the Department of Health has broken these requirements into its own statute of […]
In addition to corrosion, deposit, and general fouling prevention, responsible cooling water treatment must now also involve disease prevention. An increasingly important tool for augmenting the chemical water treatment program is filtration. While cooling water filters come in many designs, a properly selected filter offers two primary benefits: Particulate Removal – Suspended solids that are not properly […]
Corrective Action As part of an MPP it is required to denote how corrective action will be carried out as per DOH requirements shown in tables 8-1 and 8-2 of RCNY Chapter 8. The following items are categories that need to be monitored and have corrective action taken if necessary. Bacteria dip slides that come […]
Many large commercial and healthcare facilities are designed with multiple chillers that get their condenser water from a single large tower water system. During the summer months, when the comfort cooling demand is high, there is a regular flow of tower water through all of the chillers. The tower system is treated with a corrosion […]
Winter is fast approaching. It is a well-documented, but often misunderstood fact that water system damage can and does occur when systems are NOT IN OPERATION. The default belief is that problems only need to be controlled while a system is under flow and transferring heat. Not true. Some would argue that PM treatment is […]
