Acro Plus
WESTIRE ACRO SERIES
Engineered for today’s demanding applications

Accuracy
The AcRo Plus photocell utilises a filtered silicon based ambient light sensor and microprocessor control. This accurate combination provides the best energy savings and reliable operation.
Longevity
Engineered in the EU with a 15 year design life and manufactured in-house using only high quality name brand components, the AcRo series photocells are renowned in the industry for their unparalleled quality and reliability.
We pay more attention than any other photocell designer to the sky’s blue and red zones to ensure negligible sensitivity to infra-red and ultra-violet radiation.
