Economical compressed air cooling
EXAIR's new digital ETC (Electronic Temperature Control) Cabinet Cooler System, available from Good Hand UK, keeps electrical enclosures cool while minimising compressed air use. The ETC can accurately maintain a constant temperature that is slightly under the maximum rating of the electronics, permitting just enough cooling for the electronics without going so cold as to waste compressed air.
The ETC incorporates solid-state circuitry that detects the slightest change in temperature. A digital readout LED displays the temperature of the electrical enclosure, then displays the user setting when the 'push to set' button is pressed. When the setting is exceeded, the Cabinet Cooler circulates -6°C air through the electrical enclosure to prevent a high temperature malfunction.
ETC models for 120V AC or 240V AC are available. The control has a strong polycarbonate plastic housing with sealed membrane push button control that is suitable for use in NEMA 4, 4X and 12 environments. The Cabinet Cooler installs in minutes through a standard electrical knockout. All systems include a filter/regulator to ensure that no moisture passes to the inside of the electrical enclosure.
