Humidity control is an important aspect of any climate control system. Therefore, humidity sensors must be both accurate and dependable. BAPI’s humidity sensors are prescreened for accuracy, eliminating ﬁeld calibration.The Outside Air Units are also extremely dependable, featuring four of the most watertight enclosures available today.
The Weather Tight (EU) enclosure is made from a ﬂame-retardant polymer with an IP66 rating. The cast aluminum Weatherproof (WP) enclosure carries a NEMA 3R, while the BAPI-Box (BB) and BAPI-Box 2 (BB2) are made of UV-resistant polycarbonate and carry an IP66 rating.
All Outside Air Units have etched Teﬂon leadwires and are built to withstand high humidity and condensation and perform under real world conditions. This is especially important in an Outside Air Unit which can be
exposed to rain, snow and large temperature swings.
