3-9 Water Reservoir

The standard water reservoir is rotationally molded polyethylene with a removable lid. The tank is fully insulated to assist maintaining fluid temperature. All portable chillers shipped during the fall, winter, or spring, or those units that are shipped from stock are flushed at the factory with a water/ethylene glycol solution to prevent piping components prone to retaining water from freezing. During startup and when additional solution is required, refer to the ethylene glycol and propylene glycol curves in Figure 11: Ethylene Glycol and Propylene Glycol Curves on page 30. Add a pre-mixed solution of industrial quality (not automotive), inhibited ethylene glycol or propylene glycol and water to provide freeze protection to a temperature 20ºF (11ºC) below the normal chiller operating temperature set point.

Glycol and/or water, with an inhibitor, should be used to protect the materials (copper, steel, stainless steel, and bronze) in the system from corrosion. If you intend to use straight water, we strongly advise a minimum leaving water temperature of 45ºF (7ºC) or contact the service department.

Warning! Operating the chiller setpoint below 45°F (7°C) without the proper amount of glycol for freeze protection could result in a damaged evaporator. ACS Group does not warrant the freeze up of the evaporator under any circumstances.

The following glycol products are available:

Caution! Do not connect make-up water directly to the chilled water reservoir unless you have an approved automatic water make-up system installed.

Caution! Do not pressurize tank. Supply and return connections must be trapped and vented to allow vertical risers to drain into tank. Do not overfill system. Allow enough free space in tank for vertical piping to drain.

If your application has chilled water or process piping above the chiller, trap and vent the supply and return lines to allow vertical piping to drain into tank.

Note: In applications where the process or process piping is above the reservoir, take steps to prevent over pressurization of the reservoir. This condition can occur on system shutdown when the water in the system drains into the reservoir. To prevent this, a vacuum breaker should be installed at the high point of the “To Process” and “From Process” lines.
