Dwyer RHPLC-2N1F Wall Mount Humidity/Temperature Transmitter

03 Month 06, 2026

Maintaining thermal comfort according to ASHRAE 55 standards requires not only appropriate temperatures but also strict control of relative humidity. Excessively high humidity causes mold and reduces sweat evaporation, while low humidity causes dry skin and electronic static. For the central controller (DDC/BMS) to calculate air enthalpy and appropriately adjust cooling valves, the Dwyer RHPLC-2N1F wall-mount sensor is an indispensable signal transmission tool.

Dwyer V8-WP Weatherproof Vane Flow Switch

03 Month 06, 2026

During the operation of a water-cooled Chiller system, the worst-case scenario occurs when the cooling water pump or primary chilled water pump suddenly stops, but the compressor assembly continues to run. When this happens, the evaporating refrigerant quickly depletes the thermal energy of the stagnant water in the evaporator barrel, causing localized freezing. The volumetric expansion of ice will completely rupture the internal copper tubes, causing catastrophic damage. The V8-WP flow switch by Dwyer serves as a critical safety "gatekeeper," providing an interlock to instantly prevent this disaster.

Dwyer PFT-IAN-B111-S Paddlewheel Flow Tracker

02 Month 06, 2026

In the operation of water-cooled central air conditioning networks, controlling flow parameters (GPM or m3/h) in chilled water and cooling water pipelines is a mandatory input requirement. This data enables the Building Management System (BMS) to accurately calculate the thermal energy (BTU) being consumed and issue variable frequency drive commands to secondary pumps. The PFT-IAN-B111-S flow velocity sensor by Dwyer, utilizing paddlewheel technology, perfectly addresses the need for real-time measurement with exceptionally low error margins.
