Tranquility TRW vertical-stack hybrid heat-pump systems can heat or cool, with loop temperatures from 85˚F to 125˚F. A compressor-based cooling cycle uses EarthPure HFC-410A refrigerant. The hydronic heating cycle uses loop water for quiet, dependable heat. When units in the building are cooling and heating, the heat rejected in the loop by units in cooling mode becomes "free" heat for units in heating mode. Unit- or remote-mounted controls are available.
Three models have been added to the Triple-Flex line of high-efficiency condensing flexible-watertube boilers. The TF 150, TF 200, and TF 250 offer inputs from 1,500 to 2,500 mbh, with sub-30-ppm nitrogen oxide, utilizing a hybrid metal-fiber burner. The boilers have a minimum thermal efficiency of 90 percent in worst-case operating conditions, such as 160˚F return water and 180˚F supply water at 100-percent firing load. Efficiencies of up to 99 percent are achievable with lower return-water temperatures, such as those found in new buildings.

Designed to perform control and energy strategies for building-automation systems, ePIV pressure-independent control valves maintain flow regardless of pressure fluctuation. The valves directly measure flow by combining a magnetic flow meter with two-way control to offer regulation, balance, and shutoff. Flow readings are reported back to the controller.
Suitable for most air-conditioning, ventilation, and critical applications, RadiCal impellers feature an aerodynamically optimized hybrid construction that provides a continuous flow of air, increasing the aerodynamic efficiency of a fan. Compared with conventional alternating-current fans, the impellers consume 50-percent less energy and ensure 50-percent noise reduction. Compact, the impellers can be integrated into tight spaces.
Flue-draft and CO safety monitor
EBC 35 draft controls with carbon-monoxide (CO) monitors help safeguard boiler facilities. An integrated proven draft-switch function ensures the control will lock out boilers within an adjustable time period if sufficient draft cannot be maintained. The CO transmitter's liquid-crystal display monitors CO levels on location. The units' sensors have a minimum two-year life span.

Air-Conditioning, Heating and Refrigeration Institute-certified, light-commercial heat-recovery units from Fantech are powered by energy-efficient ebm-papst motors that provide 250 to 1,105 cfm at 0.4-in. w.g. Reversible door panels provide access to cores, filters, motors, and drain pans. Aluminum heat-exchanger cores are engineered to maximize heat transfer while allowing effective evacuation of condensate. Plates are hemmed and sealed to prevent cross-contamination.
For new and replacement installations, as well as additions and retrofits, the TempTracker Mod+Hybrid control is capable of integrating all Raypak and most other major boiler platforms. With an optional BACnet building-management-system link, stage-fire, modulation, condensing, and non-condensing boilers can be mixed. The hybrid-control concept helps users stay within budget guidelines while maintaining the benefits of condensing designs.
Pump Revit files
Taco has produced individual Revit files for more than 860 product models within 24 separate product groups. These include pumps, circulators, heat exchangers, buffer and expansion tanks, air dirt separators, and valves. Another three product groups, involving more than 50 products, remain to be completed and should be available within the first quarter of 2011. Taco was the first HVAC pump manufacturer to release Revit files.
An economizer system for commercial boiler and water-heater systems, the IPVB-ECO consists of an inline power venter and an integrated economizer unit with stainless-steel tubes in a compact design. The system can operate in condensing or non-condensing mode. Able to be installed vertically or horizontally, seven standard sizes can achieve energy savings of up to 5 percent.

High-pressure condensate return
Engineered to reduce energy use by collecting high-temperature condensate and safely pumping it back to a steam boiler without flash loss, high-pressure condensate returns increase the efficiency of production equipment by ensuring condensate is properly drained out of processes and returned to boilers.
CoreSense compressor electronics enhance compressor and system performance by sensing and interpreting electrical and mechanical information within a compressor to provide advanced capabilities, such as system diagnostics, protection, and communication. The electronics can help improve system performance and reliability and reduce costly callbacks.
