WHAT IS THE

PORTABLE

CHILLER?

The Conair Series 1 Portable Chillers provide self-contained sources of chilled water and are available in either water- or air-cooled models, ranging in sizes from 3.5 Hp to 40 Hp (approximate capacities of 3.5 tons of refrigeration to 40 tons of refrigeration). Pump selections are available to match most process flow and pressure requirements.

The normal temperature range of discharge chilled water is 20 °F to 70 °F. For applications requiring 40 °F and lower mix glycol with the water to the correct percentage.

The Air-cooled Portable Chiller A1 Models and Water-cooled Portable Chiller W1 Models are designed to provide chilled water for industrial applications requiring 24-hour-a-day per- formance. Units are totally self-contained for easy, economical installation. All parts wetted by the process are non-ferrous.

To operate, simply connect the power source, process piping and fill with water or ethylene or propylene glycol (but not automotive antifreeze).

These chillers are ideal for machine-side cooling to maintain process temperatures in an injection molding machine or extruder and wherever you need a small, moveable cooling unit. Nominal capacities range from 1.44 to 14.68 tons for the water-cooled models and from 1.18 to 10.95 tons for the air- cooled models. Capacities are based on standard pump sizes and delivering 50 °F water.

Operation of these units differ only in the medium used to remove heat from the refrigerant in the condensers. Water- cooled models use 85 °F (29 °C) or lower cooling water from a tower, well, or city service; air-cooled models use 95 °F (35 °C) maximum ambient air.

Choose water-cooled portable chillers where tower water or another inexpensive water source is available. Choose air- cooled models for maximum portability of the unit. Water- cooled models are equipped with brazed plate or tube-in-tube condensers. Air-cooled models use aluminum-fin, copper-tube condensers.

All standard voltages are available.
