SEMCO LLC introduced the NEUTON–Multiple Zone, a chilled beam pump module (CCBPM) capable of controlling active chilled beams in up to five small rooms in office buildings, hospitals, schools or other commercial buildings. The NEUTON–Multiple Zone consists of modified onboard software, combination temperature/humidity monitoring sensors, and thermostatically-controlled hydronic valves for up to five zones, and an original NEUTON CCBPM.
Taco has added a new Multi-Volt Zone Sentry zone valve for use in hydronic heating and other HVAC systems such as those with fan coils and air handlers. The new mechanical valve allows one actuator to accept input voltages between 120 and 277VAC 50/60HZ.
Taco’s newest Zone Sentry Zone Valve – with an inverted flare – is suited for retrofit and new construction work. According to the company, the zone valves improve the overall performance of any hydronic system that uses a zone valve. Taco’s zone valve line uses microcircuit-based logic to control a gear-driven electronic actuator that drives a ball valve-based body design.
The new JS Series BACnet thermostat from Jackson Systems combines the power of a space-mounted equipment controller with built-in temperature and humidity. The thermostats include a wide range of factory supplied programs for the following applications: two-pipe and four-pipe fan coil units, roof top units, heat pump units and packaged and split unitary systems.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
